Les, Do you have vented covers? If not the crankcase pressure
can cause gaskets to leak. I use old style cork gaskets with a light coat
of weatherstrip between the gasket and valve cover. I put the weatherstrip on
lightly and install the gasket and valve cover with light bolt tension to allow
the sealant to set. Then tighten only as tight as it takes for a seal. I'm sure
the newer gasket material is better, but I can get a good seal with this method.

Subject: [Chevelle-list] VALVE
COVERS
DOES ANYONE HAVE A SUGGESTION FOR A CURE FOR
LEAKING VALVE COVERS. I HAVE A 70 SS 396 CHEVELLE WITH THE OEM CHROME VALVE
COVERS AND CAN NOT KEEP THEM FROM LEAKING AROUND THE EDGES. I HAVE BEEN VERY
CAREFUL NOT TO OVER TIGHTEN THEM SO AS NOT TO BEND LIP. IS THERE A
PREFERRED BRAND/TYPE OF GASKET OR SHOULD I TRY A SEALANT. IF A SEALANT IS BEST
SHOULD IT GO ON HEAD SIDE OR VALVE COVER SIDE OF GASKET OR NOT US A GASKET AT
ALL WITH SEALANT. POSSIBLE STUPID QUESTION BUT ANY SUGGESTIONS WOULD BE
APPRECIATED. THANKS, LES.
