I've got a 2003 z71 Tahoe that I got the hair brained idea to cut apart with 100k miles on the clock. Dropped in a 4bt Cummins with a built 4l80e trans and stand alone controller. Now it's compound turbo charged.. has a Hummer H2 rear and 4.10 gears.

Not sure on hours. It's an '01 and has been abused for sure. The tractor has been apart for sure based on the gobs of rtv everywhere. The previous owner had it for a while and it never had gauges hooked up in the time he had it. The wiring is all hacked up and some "repairs" that have been...

I have not adjusted the oil pressure. Oil pressure was read with both a cheap mechanical gauge and my OTC test gauges to verify. After 5 hours of running, its still puff puff puffing with each firing of the cylinder and this is on a fresh oil change. It's definitely blow-by as it does have...

Well... I took a few days off work to get some stuff done around the property. I beat the guts out of this little tractor and it's still going. Lol. After being ran hard all day, hot low idle oil pressure was ~3psi. At speed, it comes up to the mid 20s. Blow-by is substantial but no...

I agree with the hg statement... just listed it as a possibility. Unlikely... but a possibility none the less. Issue isn't with bearings (although it needs them).. but with as much blow by as it has... it likely needs liners.. for sure needs rings and ive heard of instances of rings being...

Excess crankcase pressure could certainly be caused by a head gasket failing to an oil return passage in the head. Combustion pressure would be vented to the pan creating pressure. But after running it for a good bit, I don't think its head gasket related. The bottom end of this engine is...

So... thoughts on parts direct from china?

So... not to offend any of the distributors on the site... but has anyone imported parts for their tractors direct using Ali or similar outfits? At this point, I can't swing buying a short block kit from a US distributor. I am however not in a rush... so shipping times don't bother me...

I think I'm going to go on and put a head gasket in it which will give me the opertunity to check the liners and head. I got the oil pressure gauge hooked up last night and that resulted in a bit of sadness. Lol Cold idle oil pressure is only ~10-15psi. Oil pressure comes up with rpm to a...

A little update... I've noticed an odd issue. After starting the tractor and letting it run for any length of time.. no matter if its 30 seconds or 30 minutes... when I shut it down, the cooling system gurgles. After the engine comes to a stop... a few seconds go by and then it sounds...

I've already printed out a few of their diagrams. A good resource for sure. I'm sure this engine is on the loose side. Once I get a few things buttoned up, I'll put it through its paces and see how oil consumption is. It doesn't appear to be burning any oil at the moment but we'll see once...

Got home and looked at things a bit closer. It definitely has some blow by. The breather puffs with the firing of cylinders. No exhaust haze and throttle response/power seems fine... so I believe I'm going to recirculate the breather back to the intake and not stress about it. Might go...

Looks to be a Y385. Has a canister on the right side of the block as you describe and it hazes pretty heavily out of the open port on the bottom. It also has a line from the oil fill cap back to the intake. That line could be bent or plugged. Haven't looked into much on it yet. I just know...

Hey alls.. So I just picked up an older Jinma 254 from a neighbor. He used it all the time for basic dirt moving, etc. but had picked up an 8n Ford to restore. Now that he has the 8n up and running, he put this one up for sale. I checked it out.. no major leaks.. no odd noises...
