You've got that the wrong way round Rich Gems engine uses a Silicone Sealant on a Steel Sump and the Thor engine with Alloy Sump uses a Rubberised Gasket.Rich998a said:the later model P38 uses a sealant but the earlier one uses a gasket.
I think you will find this improves things. I could never really get my GEMS pan sealed up for long. My Bosch model has never really leaked more than a drop or two if sitting in the same spot for a week. What a shocking concept, make the pan out of the same material as the block and then install a gasket :lol:Col said:
