Need help LT1 problem
I have a 94 LT1 motor that has coolant vapor escaping from the passenger side oil filler tube when the motor is hot. There doesn't appear to be any water in the oil as indicated by clean oil on the dipstick. Is this a pinhole leak in the head gasket? Are there any tests that would help define tha problem? Any help would be appreciated

I would check your PCV system to make sure it is not clogged. It might not be "coolant vapors", but blowby due to a clogged PCV system. Also your rings might be worn out. A leakdown test of your cyls would answer if the rings are shot or not.
