Reply to "Grey Smoke During Deceleration"

IF you have too much crankcase pressure it will push oil past the seals on the crank.

The seals can only hold about 15psi max.

If you only smoke under that condition you created and not all of the time, you do not have an issue.

I already suggested that your rings still aren't 100% sealed. This is a symptom. You need to put mileage on the car, not just idle it.

It needs to go through cycles of acceleration, deceleration, hot starts, cold starts, etc.

Depending on the rings that are in there and how tight the pistons are to the walls also affects oil blow by.

A certain degree of it will always be there.
