grumpyvette Posted March 18, 2004 Share Posted March 18, 2004 you might also keep in mind that alot of guys (mostly the older guys that refuse to read labels )use sealants and gasket sealers that are WRONG for the applications they use them for, EXAMPLE that yellow slime (3M Weatherstrip Adhesive(item#51135). Ive also heard it refered to as "gorillia snot". that yellow contact glue like sealant is used by many guys to install valve cover gaskets, and oil pan seals/gaskets, well it was NEVER meant to be in direct constant contact with hot oil and while it will work with most mineral base oil in that application I can tell you from seeing many examples that some synthetic oils slowly desolve it over several months time , since it was never designed for that application ,you can,t blame the product! but Ive seen numerous cases where engines leaked constantly after several months once synthetic oil was used in engines using it as a gasket glue. just for your info 3M makes a better Weatherstrip Adhesive (black) #08011, part no. 051135, "a black-colored, high-strength adhesive for adhering rubber weatherstripping and gaskets to doors, windshields, trunklids, windows, and lights." btw while we are on the subject some sealants leach by-products into the oil that cause the O2 sensors on EFI engines to fail, look for the SENSOR SAFE sealants Excellent resistance to hot oil. Non corrosive to metal. Oxygen sensor safe. or http://www.k2distributing.com/pages/chemicals-seal.html Quote Link to comment Share on other sites More sharing options...
