I Still Hate My Tractor II

[The Fred]

Sold 1100, returned 110?? I think that'd be around 10%!!

Nice work, BTW.

11 were returned defective, not 110, MYbad.

I'll check the wastegate again but I had initially checked it with a Mityvac vacuum/pressure pump and the gate opened at 7 psi. I have no reason to believe the boost is any higher.

I have to check for combustion gasses in the radiator with a sniffer still haven't done that.

The oil in the rad looks so clean I hope it is simply a bad cooler. The turbo is only oil cooled no engine coolant passage there either.

This Saturday's job, Fred

You say the oil in the rad is clean like fresh.
Is the crank case oil also clean like out of the can?
If not how could the oil present in the rad have come from the crank case?

How much oil are we talking about?

 

[The Fred]

Maybe 1/4 cup. Oil is lighter than coolant so it all finds it's way out into the overflow tank.
I keep my engine oil clean.

And no pressure feed past/through the head gasket for the rock train.

Bummer.

i should have looked a little closer for coolant lines in and out of the turbo in the pictures you posted

Glad to hear that the Kubota is making respectable and acceptable power for you now :thumbsup:, hopefully the fix isn't a big deal


the sniffer test next should eliminate any combustion cross over contamination to radiator- but if it shows no gasses are found then i guess the question remains -where is the oil from? - can the oil present in the radiator be tested (compared) against the crankcase oil to determine if they are even the same oil?

Hi Fred.

Hey nobody said "I told you so" yet.......just sayin.

Fred, I have a sweet 5.3 aluminum engine sitting in the corner with 5K miles on it maybe that would work.

We didn't have to, we just waited for you to say it. I'm pulling for you to find an easy fix. I'm more or less just thinking out loud here but if you never went over 7 psi of boost, I just don't see how you could have hurt anything.

Operative word here is, "yet".

It's disappointing that the tractor was putting out the power you wanted and now this. Hoping it is a simple fix.
