Just had the clutch replaced in my 88 GT. Replaced flywheel, pressure plate clutch, release bearing and rear main seal. Mechanic followed the recommendation (Fiero Store) to not use a gasket on the cam cover and instead used the Black silicone. After all was assembled and fired up, it leaked engine oil like a sieve. Our thoughts are that the Black silicone sealant did not do its' job and should have used a gasket. Any thoughts anyone?
