Is there a "special" marine oil pan gasket i need for my 509 cid engine project or will a one piece fel-pro 1884R from summit for about $35 do the trick? Will i need to add any additional sealant and if so, what kind and where? Thanks, Dave

I buy mine from Summit or Jeg's. Use a bit of silicone around the whole thing, both sides, to fill any gaps. Oil pan leaks suck because you have to pull the engine to fix them.

do you just buy the regular one piece $35 fel-pro? what kind of sealant do you use? Thanks

Fel-pro or Mr Gasket

I wouldn't use a one piece felpro pan gasket (your talking about the blue rubber one if I'm thinking correctly) on a mk4 block as they tend to push out and leak(I tried using one and it was squeesing out while I was torqing it down,others I know have tried them on sbc circle track motors and they always leak. Use a good old fashioned pan gasket,seal the front and back with a little great stuff,sides use a shellac or permatex and if your using a aftermarket pan that doesn't fit block perfect use the great stuff on whole gasket. As a added touch,locktight your pan bolts and use new lock washers on them or use studs,marine engines seem to vibrate bolts out,Smitty
