I changed the radiator 18months ago and the rear main leak appeared 4 weeks ago. The Coolant leak was found 3 weeks ago. The heads were pressure checked and checked for cracks by both the shop and myself. Needless to say they passed. I could have the radiator checked but for the price of the...

Well it took me 50 miles of driving to get the problem to reoccur today. Would bypassing the oil cooler be a good idea with that amount of driving? Also I would have to reflush the oil again to get all the new sludge out and hopefully all the moisture comes out with it or else I may get false...

I have coolant leaking into the crank case some how on my m1009. Its not the head gasket like I thought since I replaced them and had the heads rebuilt. This is really frustrating because it was a lot of work and money. Basically here is what was happening before and again now. So at first...

which direction? I've been going clock wise at the torsional dampener using a 15/16 socket and ratchet.

So basically I have the heads off my truck and I want to scrape the deposits off the pistons before I put it back together. I'm wondering if there will be any issues with the lifters if I hand crank the engine to move the pistons. Also I was wondering if the lifters would need to be reprimed...

Well the injectors and injection pump on the truck are new but it has always had a bit of a hard warm start problem. I put in some crappy wellman 070 glow plugs and the problem got worse. I replaced them with AC 60G's and the starting problem whent away. only wierd unexplanable thing is how can...

I am wondering if there is a better glow plug temp sensor out there than the stock one. It's also called a coolant temp sensor in the TM. Reason I ask is because I have the common problem where I try to restart my truck after its been sitting for 15-45 minutes and have trouble getting it to...

Thanks Well I guess I know what to get now. they are $70 or so for a set from o'rileys. Too bad I spent $68 on these ones. I guess I have a set of extra plugs now to go in the random parts box. lol Also I was wondering are the glow plugs on a timer or do they shut off once the temp sensor...

I just bought some diesel RX plugs that are garbage. they bearly get hot enough to start the engine at 50*f. They replaced some AC 13G's that were over 2 years old and still did a better job starting the truck than the new ones I bought. I am looking to replace them but I want to get it right...

I am using the stanadyne additive. it dosnt seem to help out much

Ok makes sense I'm also at 3000ft altitude this winter vs 50ft last year

I havent noticed a big difference with the hubs locked. I'm just hopeing it just the cold thats affecting the engine. It had occured to me to maybe replace or at least retime the injection pump. the scribe marks are alined perfectly but is it possible for the mechanism to slip internally?

I have a m1009 that is getting crappy fuel economy. I've had it for 2 winters but this winter I'm in montana and its colder. I usually just drive from home to work about 7miles but on the weekends I'll drie allover town and put about 20-40 miles on the truck all day. Its been in the high 20's...

well to address a few things I replaced the ball joints with MOOG ones that have ZERK fitings about 10 mos ago because the origional spicers were shot I also alinged my front end and havent experienced any abnormal tire wear untill now. In addition after I alinged the wheels and adjusted my...

So I had my hubs locked while driving my truck in 2H for about 1000 miles while driving from montana to seattle and back over the last week and when I got home I noticed the outermost tread of either tire is now worn unevenly compaired to the innermost tread. What is the reason for this? I didnt...

I have a 1986 m1009 that has 104,000 miles on it. The last time I know the glowplugs were changed was about 3 or 4 years ago around 70,000 miles. The truck has been converted to 12v and professionally rewired by the last owner. The resitor bank was removed. the starter is a 12v and the drivers...

so when I first start it and it sounds crappier and louder as it idles and when I drive it it's high idleing? I took a look at the screw on the fast idle solinoid today when I started it it didnt move. I tried pulling and pushing on it to see if it was supposed to move or what would happen...

How can I tell if my truck fast idles? I'm not sure if mine even dose. If it dose I cant hear a difference in the rpm's from the 625 low to the 800 high. I know this only happens when the engine is cold and even then I cant tell any difference.

got mine on ebay for $2700 right after I got back from iraq. as far as ebay goes look at thier reviews. They guy had 100+ auctions over a few years with no negative feedbacks so that made me feel better about getting stright answers to my questions. And I asked a lot of questions. The truck is...

well to give you guys an idea. I will start to notice this problem after the truck has sat for only half an hour after reaching operating temperature. like when I go out to eat dinner and come back out to start the truck it will take sometimes 3-5 seconds of cranking to start it. could it be...
