E-6 front cover gasket or silicone?

Recommended Posts

I'm replacing the front cover on our 88 R model, and the original cover had a gasket. My parts man says I should use silicone or expect leaks. Any thoughts?

I'm old school and still use gasket shellac, (Indian Head). I only use silicone if the surface is imperfect; however I like the gray Permatex, (high torque) under a rigid bolted cover like that.

Never have worked on that late of E6 I'm aware of however.

If it has a stamped steel timing cover use a gasket. If it has a cast aluminum cover silicone. Being a 1988 I would assume  it is a four valve with a cast cover.

Use 3M weather strip adhesive on the steel stamp covers to keep the gasket from squirting out. Glue it, let it set up for a spell before installing covers, no comebacks with that stuff.

Cast... don’t  use any sealant. If the cast has a cut relief (in ribbon land) make sure there is no oil and completely dry during installation.
