First post here, I hope its ok to ask a question. I have a 97 3500 and I'm getting some vapor and a few drips of antifreeze out of the blow by tube. It only appears when it warms up after the thermostat opens. The bottom of the oil cap and visually the oil both look clean. The pickup was all stock up to about 1000 miles ago. I ground the fuel plate and did 4k governor springs. When I redid the head i out in 5x.011 injectors. It only has 135k miles on it now.
I just replaced the head gasket thinking this was the problem. I had the head checked out, surfaced and gone through. Used new stock head bolts torqued to 130 ft lbs and a thicker gasket.
Kind of stumped I'm wondering, would it be a crack somewhere in the block or could a bad oil cooler cause this. The motor runs smooth with no missing and isnt down on power.
