View Full Version : PCV smokin, coolant N oil

So what would you assume if your PCV breather mod was smoking?

There is coolant in the oil

What all could let coolant into the oil?
1) head gasket
2) upper / lower intakes & TB gasket
3) front (timing) cover gasket
What else?

Only one of the above is the head gaskets. I am thinking of a cracked head if not that. Hope that helps.

Mine did the same thing. It smoked out of my vented catch can & I found coolant in the oil. I tore the motor apart and among other things it was blown out rings & a cracked cylinder wall. I know that doesn't make you feel any better. Best of luck to ya!!

yeah only think that would let coolant get in the oil would be head gaskets, cracked heads, or cracked block. The intake doesn't have any coolant running through it and front cover doesn't either

Also coolant in the oil isn't good the the bearings at all. I hope it wasn't like that for too long.
