I have white smoke blowing from my rocker cover breathers and out my exhaust. The car was running fairly good, would rev fine but would quite idle. We checked compression - results were good even compression on drivers side bank and NO compression on passenger side. The motor was supercharged last time it was driven, which has caused this whole problem.

so why have I got white smoke out both my tapper covers and exhaust?

HI there,

I would be checking why there is no comp in 4 cylinders first, do a wet & dry test see if its rings or valves start here.

We tried dry and wet tests and neither registered any comp on passenger side bank.

Hi there,

Well either all the valves are faulty, or you have blown out 4 pistons, a leak down test will tell you where the comp is going.
