Blue smoke out exhaust after cam swap Just did a cam swap in my lt1 with new pushrods, rockers, springs, valve seals etc. The car ran fine for the first couple hours but now it's blowing blue smoke out of the exhaust at all times and it's cutting out pretty bad while driving. Can anyone help??
I've heard it could be valve seals or oil leaking into the intake?

Rechecked a few valve seals and they seem to be fine...pulled 2 plugs out each side of the motor and they all look the same with oil on them. Compression is 160 in cyl 1, 185 in cyl 3, and almost 190 in cyl 4...it smokes pretty bad in about 200miles I ran it from full til the low oil light came on. Would new valve seals cause the rings to go bad after about 60 miles? Or do you think the intake is sucking in oil somewhere?

Ooooh boy. I sandblasted the intake manifold while it was off, and I just changed the PCV valve. There was some sand on the end of the old pcv..............
