As I was throwing out the old oil pan gasket, I noticed that the seal had silicone on both sides of the mating surfaces. The oil pan seal is a 1 piece silicone seal that had multiple ridges on the side that mated to the block so I thought that it didn't require any sealant. ??
Should I have??
Thanks in advance
Yes you thought right. I am a firm believer that most gaskets are designed to be installed dry as possible. I have had thousands of gskt experiments and I have found that silicone creates a slick surface allowing the gskt not to adhere to its mating surface. When installing a gasket, unless the surface is pitted or un even, a dry gsket should seal, also take into account that some tight corners may be more difficult to seal such as where cyl heads or intake corners meet. I hope this info has helped!
