Blue Smoke Rollin

[djg]

I am no expert, but......., the vent hooked up to the muffler seems like it could pressurize the crankcase, not siphon it. That's where turbochargers get their power from, exhaust pressure. Perhaps this modification and the vented oil cap were a former owner's attempt to deal with excessive crankcase pressure from ring blowby. Please let us know how it runs after you remedy these two items.

With 4,000 hrs recorded and then more time after not being recorded, it could very well need an overhaul depending on how it had been maintained. Hope cleaning out the vent caps and disconnecting the tube to the exhaust will help.

Good luck with it.

Is the 5050 you bought for 6200 from the junk yard place? As mentioned with that many hours it sounds like it needs an overhaul...and a lot of tlc.

That would be a big 10-4 on the junkyard. Have made several unhappy trips back to them for "warranty issues". Little by little am working out the bugs. We lowered the oil back to just below max to see if it fills back up (hydr or fuel entering crankcase), cleaned out the breather on the crank case (black gunk and oil poured out), disconnected that hose (now we have to plug up the one on the exhaust), and checked for leaks around the exhaust manifold. It definately appears as if the gaskets are bad...we are ordering a new set and want to check the injectors. It really appears it is running very rich. Still have blue smoke coming from the exhaust, but Im hoping its just some leftover oil from the overfill. This is definately going to be a challenge, but I still believe that in the end, we will have a pretty good tractor. (polly anna, I know) Thank heavens we have someone who is really willing to help us tear into it (thank heavens for rain right now) They did tell me at the junk yard, this time, that apparently before they got it, the owners had pulled the motor and replaced some things...what I don't know...since according to them he has since passed away (I've got ocean front property in Arizona for sale too) Anyhow...if anybody has any other suggestions for us..given what I've described that we have found and done...I greatly appreciate it. Your suggestions give me starting places for problem elimination.
Thanks again

Depending on where and how it is connected to the exhaust it could have pressure or vacuum going to the crankcase.
A turbocharger get very little of it's drive from exhaust pressure, it is primarily driven by exhaust heat. Work's kind of like holding the pinwheel over a candle and it spins like crazy.
