Marv 983 #1 Posted March 1, 2013 Do you use gasket sealer on oil pans? Marv Share this post Link to post Share on other sites
rmaynard 16,350 #2 Posted March 1, 2013 (edited) When you are dealing with a cast iron block and oil pan with machined contact surfaces, if both surfaces are properly cleaned, the gasket is of a good quality, and the bolts are torqued to the proper specs, there should be no need for any sealant.

MalMac 1,332 #3 Posted March 1, 2013 I second what rmaynard said. Making sure the two mating surfaces are super clean goes a long way in making sure you get a good seal. You just got to watch the quality of gasket you get there is some real junk out there. Share this post Link to post Share on other sites
Kelly 1,033 #4 Posted March 1, 2013 I've had issues with gaskets weeping, not a real leak just wet and looks bad on a clean restore, so I have been painting some of my paper gaskets, let it dry 90% of the way then install it has stopped that problem, I think it's just from the gaskets being cheaper and soaking up the oil.

VinsRJ 723 #5 Posted March 1, 2013 (edited) I use sealer all of the gaskets... just a hint of it... never-a-leak or a weep. Edited March 1, 2013 by VinsRJ Share this post Link to post Share on other sites
Marv 983 #6 Posted March 2, 2013 I am working on a Kohler K532 The block is cast iron but the pan is aluminum. Wonder if the dissimilar metal makes a difference. The service manual of course never recommends sealer. I don'd want to pull the engine again so I want to do it right. Marvin Share this post Link to post Share on other sites
