I am in the middle of a clutch job and noticed the bell housing had a little to much oil on it and in it for my liking. The clutch was not wet, but worn on the outside pretty well and enough to cause slippage.
Looking at the oil pan and behind the intake rear seal, they both were wet with oil, so I decided to replace both oil pan and intake with new gaskets, while the drive train was out of the car.
I have a FELPRO 1 piece for the oil pan, and the old 4 part intake set for the top end.
The car did burn some oil at times and a bit smokey when at idle, so I had decided to just redo the intake during the off driving season, then the clutch slipped so here I am.
Anyway, today I pulled the top end off and noticed that the INTAKE gaskets all had RTV applied end to end. I know the front and back rubber seals get that treatment and are a classic leak point on these small blocks, but never have I seen RTV on everything. I have always applied the intake side gaskets dry.
I am thinking that over time and heat cycles that RTV begins to break down and allow seepage to occur thus allowing oil to be pulled into the cylinders. Not a large amount, but enough to burn some oil to cause it to smoke from BOTH side pipes.
When I bought the car in 2009, it had been rebuilt with only 500 miles on the motor so guess it was done this way in the build.
BTW I got a Mcleod performance clutch kit, new flywheel,and associated other parts and some New Foose Nitrous R/T chrome wheels.
