Is there any way to stip the oil leak from the rear seal ? YES i have ad a mechanic take it appart clean and replace the seal ! So just Tighten the nuts ?? I plan removing the front cove for the third time and attempt to stop the leak .Ive used TAD gaskets really no difference. This time im using Plumbers goop , Im told apply both cleaned surfaces and let it 3/4 dry and mate the two surfaces and hand tighten the nuts . Next day start the tighting pattern . I know a friend that used this method and he has no leaks ! Am i expecting to much for my perkins to be on the same page as Me ? Im going cruising next year so i need to start now chipping down my list !
