My 86 Z28 was seized when I tried to start it tonite (it has not been run for two days)When I opened the hood I noticed gas on the intake manifold. After taking off the air cleaner I could see gas dripping from the secondaries. I pulled the dipstick and the oil is mixed with gas. I assume that the engine is hydrolocked. So guys, what happened? and what do I do about it? I recently swapped the motor in from my 79 Blazer and have had no problems so far. The motor is a 350. Edelbrock Performer intake model 3701 (emmission legal)with a Holley 4160 600cfm carb. This same setup ran in the Blazer for two years with no problem, so I assume I did something wrong when I put it in the Z.
