I never used a breather cap. I have no oil on the intercooler fins.
Never had oil in the throttle body. I ran stock level for the oil also.

 

What are you doing with that intake off????Damn..that looks super-clean!!Almost new if I didn't know better.

 

The extreme of detailing

 

Oh, I forgot. 15K miles

 

I just had the recall performed on my '99 and asked to see the original I/C. It DID have a film of oil all over it. 3 days later I put a breather on my truck. Oh, my truck had about 16,500 miles on it at the time of the I/C swap.

 

alright, im confused about this whole oil thing? i have a new 01, what should i be looking for, and how can i prevent it from happening?
