Oil Pan sealant and gasket Merc 450 slc
HI All
I currently busy with an overhaul. I have removed the oil pan and cleaned it, However the original gasket is intact and stuck solid to the oil pan. I have purchased a new gasket. Now, do I remove the old gasket , which may be very time consuming. Or could I just use some RTV sealant on the old gasket stuck to the oil pan and install. or (this sounds silly) could I just place the new gasket onto the old gasket , using the RTV sealant in between and install. any thoughts ? c |

I would remove the gasket to install the new one WITHOUT sealer. I'd use a gasket remover or aggressive paint stripper to soften it up and a low speed wire wheel to actually remove it without damaging the sealing surface.

Use Permatex "Aviation Form a Gasket" with the gasket.

Quote:
It is indeed very tedious but not as tedious as continuous oil leaks or worse still having to to the job again. Do not put a gasket on a gasket with extra goo - you are wasting your time and probably moving the leak to another place (think about crankshaft seals) ############## Get some gasket remover - usually spray on stuff in a can. Works a charm. Use a plastic scraper on aluminium alloy parts. ############## If you are worried about leaks or corrosion between ferrous and non ferrous parts consider a gasket dressing such as Hylomar
