Stubborn Sealant

Like brake cleaner or mineral spirits, gasket/sealant remover is a poisonous chemical and the proper protection (gloves, eye protection, and a respirator) should be worn when using these chemicals. Mask or protect any areas that may be damaged, such as painted areas or the lifter valley where a caustic chemical can get into the oiling system and break down the lubricant causing ring or bearing failure later on. Let the sealant remover sit for the necessary period of time and try to remove the stuck-on sealant... Photo: Ryan King, 2005.
