I've had nothing but luck ordering through lmctruck. I'm actually getting a list together to order some stuff for my new truck.

Yep sounds like its leaking. I don't know if there is a rebuild kit or now. I have always just replaced them.

I also agree with the stealth plate. I had a wire actually break in two and was almost impossible to solder back together.

I agree also to check your vent. Speedy sleeves are pretty easy. Put a little Loctite on the inside and find something to help hammer it onto the yoke.

Like said before the fans are only needed in slow speed/stop and go driving. I have also seen many times that electric fans can't meet the demand needed by a towing diesel truck. On my 01 that I just bought the mechanical fan went out so the guy had an electric fan out of a grand Cherokee that he rigged in there. I don't really think it pulls much air but I havn't tried it. If you wanna test is the fan is pulling air, I was always told to stick a dollar bill in front of the intercooler and if it holds it up, its pulling enough air. Just my two cents.

I know this is a long shot but hook a ground to the thermocouple and see if that helps, might be loosing a ground in your wiring.

I should of used better grammar and said I have never seen a vp without a support bracket that runs from the vp down to the block. I have never seen a gasket behind the bracket where it mounts to the block but when I was doing research on the tappet cover I kept coming across people saying there is one. So when I do the tappet cover I'm going to do a how to and take pictures.

Every vp44 I have ever done has the bracket. They might have forgotten to put it on if your vp was replaced

I have a theory on what was going on here. The connector tube o-ring seals out air from getting into your fuel system. So if you have a bad one it lets air bleed back your fuel. You cannot measure air molucles(sp) so you can have an air leak but no fuel leak. Usually if you have a bad connector tube o-ring it will be hard starts cold and start normal when the engine is warm. I would have to look at he injectors to see if there is actually fuel return going past the connector tube but Im thinking that the o-ring on the injector blocks the return fuel.

I have the same exact oil leak as you described. I ordered a tappet gasket today and gonna replace every gasket i can find on the drivers side of the engine. I have even read there is a gasket where the vp44 back bracket mounts to the block. But, i have never seen it in the 40+ vp44s i have done. Im also gonna add some dye to my oil before i start so i can do some looking while im tearing everything off to get to the cover.

Been watching this site for years, havn't been on many forums lately since I had to sell my 06 megacab. Just picked me up my third cummins (other one was a 02) its a 2001 sport, auto. I sure did miss the diesel. If you guys have any technical questions, I'm a former Dodge/cummins tech and spent many of years under the hood of 2nd/3rd gen trucks. I still do some side work, which keeps me busy.
