then my guess is on the gasket between the filter head and the block. You should be able to see an oil line trickling down to the filter. Hate to think what they charged you guys, but id have it back in their shop demanding a fix!
Take that hose off next time. Your going to push your seals out.
other then that i cant see how a vac leak would cause that code. I would ask the 1J guys.
im surprised the dealership even did the machine work and what not.
make sure the oil cooler lines arent leaking and that the relief spring bolt is tight!
how are you pressurizing the crank case (and head) from a boost leak test?. im guessing you left the pcv hose attached to the intake and stuck the tester on.
you can use a socket extension with a small level to keep the drill strait. No way your going to talk me into removing the head to helicoil... now if its already off...
When the stock size helicoils pulled out on a few holes i unraveled the helicoil from the other 5 holes. None of them...
seems it was flirting with a full blown bhg then! Sucks to hear the PO lacked the attention to detail the 7m needs. Seems to be the usual case for alot of car.
good luck with it man!
