Reply to "Grey Smoke During Deceleration"

I have the intake off again and everything looks perfect.  It does not look like oil is getting past the intake manifold gaskets on this go around.  I called Wilkinson and he is thinking there was too much crankcase pressure during the hard deceleration test and it pushed oil up cylinder walls into the combustion chambers.  The cylinders with the lowest compression are on the driver side and that is where the smoke appeared.  He suggested doing the same deceleration test with the PCV valve disconnected.  I get a new set of gaskets tomorrow and plan to test again on Monday as the silicon will be cured by then.

Jack, I pulled the retainer for the lifters and found they had drilled four holes likely to help oil find its way down from the valley.  The two holes without arrows are for the bolts.  I will continue with this setup for time being.
