Oh I’m definitely holding on to it, I’ll probably find a n/a down the road and build up a spare with the turbo parts- Heavy foot

Unusual coolant in oil/oil in coolant issue
Damn sounds like I ended up with a lemon, a rebuild is more or less out of the question at the moment, I don’t have any local shops I would be able to have the block and heads checked out at and the cost would probably be more than I want to pay for this motor, I suppose I’ll start looking for...- Heavy foot

Unusual coolant in oil/oil in coolant issue

Unusual coolant in oil/oil in coolant issue
Today I pressure tested again, checked all the exterior cooling system with soapy water and found no leaks.

Unusual coolant in oil/oil in coolant issue
Thanks guys I’m hoping it’s not a head gasket but I’m sure I’ll find out soon enough, I’ll try the constant air test tomorrow and see what I find, I’ve already gone over most of the cooling system with soapy water but I didn’t have a ton of time today, maybe I’ll find something tomorrow- Heavy foot

Unusual coolant in oil/oil in coolant issue
Hello oil burners, this is my first post and I want to start out with thanking everyone on this forum for all the guidance I have used in the past on here, it really is a great resource for these old diesels and it’s saved my a$$ a few times. I have a 94 turbo 7.3 idi that had a fluid mixing...- Heavy foot
