Oh yeah, be easy on starting fluid, it likes to soften the carbon in the ring land area and will cause the compression rings to stick after the carbon gets hard again. The result is no compression and the fix is a re-ring

In the "conversations", you stated that the fuel pressure is "fine". What does "fine" equate to in a measurement? That is an important measurement. Start with basics, Check the timing, if that's gtg, make sure the fuel shut off that was removed is being pulled up to the proper distance, if too...

Older C series engines were prone to cracking in a few places, injector bore to valve, between valves, spring seat area and between the liners. If you get a newer casting head as a replacement, the head cracking issues will be no more. Look between the liners for cracks. If there are cracks...

I second the oil temp. Brake pressure is a good thing too, my Dad had an old GMC that had a brake pressure gauge.

Post 71, Don't know if he noticed, but he took very good pics of the failure. 5 and 6 cylinder exhaust seats dropped. When they drop, they break up into little squares/rectangles. The pieces will migrate back into the intake and get into other cylinders and the air compressor, remember, it...

Just enough to take the squared off edge and split it on the same end, the radius allows it to slip into the tappet easier and the split you make allows the dowel to be pushed into the pushrod area of the tappet, it is a shade under .500. You need to pull the fuel pump gear, time the engine and...

Cam is easy. Go to the local hardware store, get 12, 1/2 in od pine dowels. radius one end and then use a hacksaw to make a split in-line with the dowel. Forgot, you also need rubber bands. remove the push rods, drop the dowels into the pushrod hole split/radius end first, use a bit of force to...

^^ No, don't do that. That screen is not a filter like one would think, it is there for one reason, ONLY to catch pieces parts from a pump failure from getting into the injectors and taking them out too/ It is not something that needs service on regular intervals. If there is debris in it, there...

I have seen an ENGINE run backwards. When was the last time you saw your engine run, forward, backward, at all?? :shrugs: Just poking you with a stick!!

It came out of an International......I would stay away from low flow cooling. Not just a simple matter of changing radiators. LFC engines were notorious for being chronic overheaters.

Just something to throw out there, I don't think a standard air ride seat will fit in the cab and give you a comfortable position to drive it, especially if you are 6' tall or a larger guy. 2.5 and 5 ton trucks had air seats, you should check to see if Eastern has one they could install from a FMV.

4L3785 still looks good! I miss that truck. Good to see that it is still making trips to the dirt. It worked very well.

Ok, so far this is what I have found...3908750 is the piston the above esn starts out with. it does supersede a few times and there is a service bulletin regarding the changes...it is nla on QSOL, but I most likely have it in print from back in the day. All other numbers except 3929161 are...

post an engine serial number and I will post that info.

Just a heads up, the 3929161 is not the same as any of the other p/ns listed. shoot me your esn and I can see if that number is a current one for your engine. I would hold off on installing them.

Seal away!!

When you put the lift pump into the system, did you go directly to the pump or thru the entire system? Easy checks first, get a clear line and go directly from a clean bucket of fuel directly to the pump, it's ok to run for a bit with unfiltered fuel. If the pump sucks the fuel into the pump and...

In some industrial and marine applications, supply fuel location is higher than the engine. If there is 250-300 gallons of fuel in the tank, how much pressure is on the inlet of the pump? Pittsburgh Diesel has been using a high output pump to force feed PT pumps for ages. To the above post, did...

While I would LOVE to, right now, laying on my back nursing a sprained SI joint. It would be great to see everyone, Aint seen 100dollarman in ages it seems. Didn't even do the pyro gig, had to cancel.
