The rescuer becomes the rescuee (M35A2 issues)

Texas is getting rain this year. Some of us have gotten 20 inches just this month when we normally get around 4 or 5 inches for May. The ground is saturated and any thing that falls now is going to run off on the surface. We got more than 3 inches in about an hour here yesterday afternoon.


I made it home from a flag retirement ceremony at the American Legion in the M1009 just fine. Colton made it home from a band competition in RED just fine as well. We were warm and dry waiting out the storm. Then we find out his girlfriend who was at the same competition still wasn't back from Austin.

The state finals were held outside of Austin. Colton competed early and his group came back to the school. They left Austin just as tornado warnings, floods and sever storms hit. Those like his girlfriend who still had to compete were shoved into shelters, let out, back into shelters, competed, sheltered and finally started out for home.

When it came time for her to drive herself home from the school, she was leary. Flash flooding and road closures everywhere, several creeks to cross and very heavy rain fall. Colton offered to go get her at the school in the Whistler and drive her home in it. I figured going along would be a good idea. Off to the school we whistled once I called her mom and let her know what was going on.

Once there we decided that her and Colton would follow me in her vehicle. That way I could clear the road of any obstructions, test out any water crossings and generally be a guide.

I actually had a chance to use the defroster which worked great (Thanks Warthog, I picked it up from you 6 years ago and this is the first time it was actually needed.) It also made the cab very hot. My normal driving style is front glass open and windows up. I had to have all glass closed due to the rain so the side vents got popped open which never happens.

Leaving the school with them following, the engine missed a bit and wouldn't pull more than around 2,200 rpm. Even though I had just put in new filters a few months ago and had clean diesel in the tank, I just thought "filters" and kept driving. It idled fine when stopped at lights in town. Once out on the open road again, it pulled fine until I noticed the cab was full of exhaust smoke.

That was new. I just thought maybe the replacement J pipe from a few years ago was leaking and closed the passenger side vent. Continue the mission. Then it filled up again with smoke. I closed the drivers side vent and it went away. Something was wrong but I kept going. Get her home was my mission. 5 miles out of town we came to the first creek crossing. The bridge was just above water and the approaches on both sides were ok. However, a field next to the creek was draining across the road. I slowed down, saw buckled road under the water, but no sink holes and the water wasn't that high. I went on through and they followed without issue. Getting back up to speed from that slow down just wasn't happening. I had no power or rpm's. The temp gauge was actually bouncing a little right at 195° or at least what I think is the thermostat temp. Another new issue. "Head Gaskets" entered my thinking.

I pulled over to drain the 3 filters with the engine running on 3 clicks of the hand throttle. The idle dropped with each drain opening, but it never picked up after closing them and only clean fuel came out. I made it another mile before the engine just sputtered and died.

I got off the road and went to draining the filters again. A fast look around showed no other leaks or issues on the outside. About that time a guy in a D2500 showed up, said he was VFD and asked if we needed help. I said we were fine but asked about the road conditions to her house. He said they were ok and offered to escort her the rest of her drive. He did that and the girlfriend made it home safe and dry.

Now if only Colton and I could do the same. My fuel gauge said a bit less than 1/2 tank. My gauge stick said we had over 6 inches in the tank. I drained the filters, got it to fire up cranking with wide open throttle and we were rolling home. We got maybe 1/2 mile. Repeat and another 1/2 mile. We had 12 miles to go and there weren't very many more places I knew I could pull over at coming up. I wasn't sure about the batteries and starter surviving either.

I had to make the call. Jennifer took the call with more humor than I was expecting. She started toward us in my M1009 with tools and fuel. Colton and I got it fired up again and just running on the 3 clicks made it almost a mile to an intersection with lots of room for us to sit on pavement and out of the mud.

We did the filters again, but I had lost hope in that excersize. I was thinking fuel pick up line hole or something in the tank by now. The guy that escorted the girlfriend home came back by to say she was home safe. Another VFD guy from that area stopped and we talked awhile. Incredible lightning show to the East and amazing sunset to the West. It was a good spot to be stopped at.

We made up a plan while waiting. Add 5 gallons of fuel and start driving slow. I would drive as long as it would run at 25-30 mph. If it stopped again, he would continue home with Jennifer in the M1009. Returning in the M715 to drag me home. The Gasser had no brake pedal last week when I got in it and I haven't traced that down yet.

We added fuel, coaxed it to life and it ran all the way home. I never took it over 1,500 rpm and had to keep 2 clicks of the hand throttle for it to idle.

It was late, I was soaked and was just glad to be home. Now I have to figure out the problem. Besides pulling the pump to inspect the lines, looking at the J pipe and checking the coolant level. I am really kind of lost on what else to do. Which is why I am going to finish typing this and then go looking through the manuals.

I had every confidence in the Whistler to get me anywhere I wanted in just about any conditions when I started out. I know there are a lot of readers who could be in the same rising water situation I was in last night with the same basic vehicle. Check things over a second time before you go. You don't want to end up making the call like I did. Or being part of the wrong side of a rescue situation.

I have some friends in Houston and Austin and they said they have had lots of rain!!
I am from Austin and have seen it rain hard, but never like this I guess.

Glad everyone made it home. We were an island on Saturday. One crossing I might have tried in the deuce since even if I couldn't make it the area was wide open and could never get more than a few feet deep and I could sit there for days without worrying about getting swamped. The other crossing was over 5' under fast moving water so not even a consideration. I've been waiting for a call for help and hope I can accomodate if needed.

I, too, think of my M35 as reliable. When do you need that, if not in a situation like yours. If the truck doesn't perform, one feels a bit abandoned.

Ultimately, it is not the truck's fault. It's a machine and sometimes it will fail.

It still is not a good feeling. I hope the defect is something simple and easy to fix.

Yesterday was the most intense rain and wind I have been through since I weathered hurricanes in Corpus Christi. 6.5" of rain at my house with 60-70mph winds. My house is on high ground, and no wind damage, so all is well here. Haven't been out to the farm yet to check on damage there. That's high ground too.

Others around here have not fared so well.

Cheers

Good possibility that the pickup screen is full of spooge! I'd certainly start there were it my truck.

Tim, you are a great story teller! I always enjoy your posts! And I'm sure Colton's girlfriend (and her mom) are very happy that you stood ready to help.

In this case, I'm sorry to hear about the mechanical issues but very glad everyone made it home safely! I have no doubt you will diagnose the problem and soon find renewed confidence in your truck. Keep us posted when you determine the cause.

Kenny probably nailed the cause. It pushes pressure just fine with the pump on and engine off for filter bleeding. Yet won't keep the engine going at any sensible rpm. Until it sits a while as I did waiting for Jennifer last night. I also never heard any splashing or other sounds associated with fuel coming out of the line inside the tank. I haven't yet made sense of how adding fuel helps the problem which leads me back to a possible leak on the line inside the tank though.

I hope I didn't convey in any anyway that I blame the truck. It is my truck, has been for almost 7 years and totally my fault. I honestly don't think I have ever pulled that pump out either so it really does come down to me not checking. Be it crud on the intake or a bad clamp or a pin hole in the metal line.

Rory, watching the tv weather I kept thinking about you and your surrounding friends. You guys were in the 10 ring a long time yesterday afternoon. I'm glad all seems to be well.

Mark, put the body plugs in and drive the Goat!

This is one thing that still amazes me. People here (on steel soldiers) will get a 40 year (+) old truck and just change some filters and expect it to run forever. The very first thing I did after getting my great running truck home was to tear down the whole fuel system and rebuild it. Tank cleaned, check. New fuel pump and hose, check. New fuel lines (stainless steel PTFE ) check. New filters (spin-on) , check. Go through injection pump and buy spare Hydraulic Head, check. Check all injection lines and injectors and buy New spare injectors, check. Then I started to run it. Now I know the fuel system is new and will last a long time. I'm rebuilding the brakes now, even though they worked just fine and the air-pacs where in great shape. Now I know the brakes will be OK. I will be rebuilding the transmission later this summer and then I will know that it is OK. People here need to get proactive on the maintenance of there trucks. At work we have regularly scheduled maintenance done on our buses. The injectors are changed out every 50,000 miles. The transmissions are given an inspection and fluid changed out and samples sent out for analysis every 6 months. The engines are inspected every 6,000 miles with oil and filters changed out and samples sent out for analysis. The list goes on and on what is inspected and changed out regularly. The military also did this just read the TM's. Now I know that everyone here cannot afford to change out parts on a regular basis. They need to wait until they fail, but inspections are free ! You can drain the fuel in your tank and check for rust and while your in there check the fuel pump and hose. You can change out your filters on a regular basis. You can inspect the oil level of your transmission and transfer-case and differentials. You can inspect your brakes and fluid level. If more people did this there would be 70% less posts about "why did my truck just die ?" . I know I'm ranting, but this simple thing (inspections) can save your bacon in a "the world is coming to an end as we know it" scenario. Like what is happening in Texas right now. OK, rant over. We now return you to your regularly scheduled programming.

Rusty, I agree, but it seems to me like the stuff that usually takes a truck down is stuff you can't see on inspections. I guess that's the reason for going through everything and changing certain parts such as injectors every so often.

With as much trouble as there seems to be with fuel systems, I think I will leave a pressure gauge on mine permanently...

I would be willing to bet that Barrman has more mechanical experience and treats his vehicles better than 95% of the people on here. He teaches auto mechanics for a living so stumping him is not easy. Before you go ranting about someone not knowing how to care for their vehicle or knowing what to do with it when it breaks down in an emergency I suggest you get to know the person vesus just jumping on an internet thread to bash them. Save that for the folks asking about where to get a CUCV key.

And you think the military, with all of thier maintenance, oil sampling, etc, never has a mechanical breakdown? Why are there so many military tow bars around?

Tim has put a little more time in his trucks than the average idjit. He has done a stellar resto on his m35 gasser. I've been to his place and he has one heck of a collection.

As an MV newbie, I find discussions like this very helpful. I want to understand what can go wrong, how to prevent it, diagnose it, fix it, and prepare for it. I've learned a great deal about how to maintain my truck, what I need in my tool box, my skill set, and in my spare parts kit. I look forward to hearing the resolution on this one.
:popcorn:

This thread inspired me to order new socks for my truck, and to make plans to pull my tank and inspect the innards.

Some boats have a separate fuel polishing system designed to remove any crud from the tanks. They have an unfiltered fuel pickup (no sock) so it will suck up any crud, a pump that can handle the crud, and a filter or centrifuge to remove it. Sometimes the fuel pickup is at a low point in the tank specifically designed to gather any crud. Sometimes the return line is intentionally run at high pressure with the last few inches of hose flexible, so it sprays fuel around vigorously and stirs up any crud so the filter can remove it.

I have a number of filters, separators, centrifuges, high and low pressure pumps kicking around from old fuel polishing projects. I've not yet decided how/whether to use this on my MV. My goal is reliability and ease of maintenance, so I don't want to add unnecessary complexity.

If I had a vehicle with big tanks that spent a lot of time idle, I'd certainly consider a fuel polishing system. I'd put it on a timer to run a few hours a week, so the fuel would always be clean and ready to go. I think of the fuel polishing system in the same category as the trickle charger I leave on the battery of a seldom-driven vehicle. It keeps the truck healthy an ready to drive.

My deuce sat for years, 10 or 15, with the tank FULL of diesel. It wasn't very cruddy. Dry desert and tank being full doesn't give room for rust to form.

Some interesting comments. Thanks for the support those that offered it.

Most of my post on any website are written to help others that might encounter the same issue some time down the road. I don't make post just so I can see my name on the computer screen. I also write in what I think is a self defacing or very humble style. Just so I won't come across as pushing myself or some agenda.

Now, on this particular problem, I could have just fixed the issue and never posted a thing. Nobody would ever know it was all self induced by me running WMO for a few years when fuel was up around $5.00 per gallon. Instead I am going to finish the story. No matter how it makes me look. A little back ground might be needed though.

Warthog bought my M35A2 WW from GL in May of 2008. He got it to his storage area along with 3 other M35A2 trucks. Sermis bought two of them and Boxcar bought the last truck. We went together to bring them all back in October of 2008. We took 150 gallons of Sermis collected waste motor oil. The two trucks pulling got topped off and my truck got mostly full as well before we left OKC.

I had a drum of WMO at the house already so as I used up fuel the next few months, WMO got filtered and pumped in. Depending on use and the price of fuel over the next 6 years, WMO and or diesel were run through the truck. Last summer I drained the tank of everything. Added 10 gallons of diesel, ran it 40 miles or so and then drained that mixture out of the tank. 40 gallons of clean diesel were added. Looking in the fill cap, the diesel and the tank looked clean. This was the first time since 2008 that I know the truck was running on just diesel.

Coming home from the Texas Rally back in March Colton was driving the Whistler. It had less than 1/2 tank of fuel when we left College station and it died on him at a stop light half way home. We were blocking traffic with that truck and my M715 with a trailer attached. So, I didn't check anything. We added 10 gallons of diesel and it fired right up. I wasn't driving the truck and didn't know what it indicating when it stopped running. I just figured he was playing with 4th to 5th shifts following me and used up way more fuel that I estimated he would need for that trip. It wouldn't idle after that. We changed all 3 fuel filters and cleaned out the cans. Perfect idle, right to 2750 governor check rpm and all was good going down the road. Problem fixed.

100 miles of driving between then and two days ago. I had no reason to think anything was lurking to bite me in the back side. Yet it was. I pulled the pump last night and found a mess. I cleaned it all up and now it idles great and revs great. I didn't have time to test drive last night but will today if the storm on radar doesn't hit. I was too covered in goo to take an after picture. But, the before picture is pretty telling what WMO in the tank can do over several years.

I have another good fuel tank and might swap that onto the truck. First I am going to run the current fuel supply down pretty low, drain it, remove the pump, clean it if needed and then go from there.
