Hi All,

Do all the different versions of the 8V71 use the same oil pan gasket?

Thank you,
Bob

Depends on what style of pan you have.
Some are called, some are sent, some just got up and went.

Which ever gasket you get I would avoid the cork type. I have never had any luck with them. Leaks eventually. Go for the heavy gray paper type.

Thanks, I ordered one from Luke.

I thought the cork type was for use on the pans with raised ridges punched into the flat that the gasket contacts. We've never had issue with cork or heavy grey paper type but the pan has ridges.

The secret to cork is not overtightening and do it even,Luke will send him a cork gasket the paper gasket works good on the adapter above the oil pan

Cork works fine if no oil film. Only use gasket sealer on one side. Other side against clean, not oily, and dry. Lacquer thinner works great to remove any oil film. Better than solvent, because it dries faster.

That's probably why never an issue with cork here. Torqued to minimum range in 3 steps only after totally dry installation - no oily residues nor gasket compound. After a few hundred miles of run under load I retorqued  again. Good to go leak free for long time...
