Same here. It made me a little nervous that the intense site listed a paper gasket and the rubber seal and then i took my stock one out and there was no paper gasket to be found. No leaks here either without using the paper gasket, you should be fine.

That'* good to know.

Mine has the gasket and all my other cars have always had the paper gasket. Finally, an improvement that works!

Ok I got it changed out and apparently there was NO gasket on the the housing, so I didn't put one on.

Just in case though, I bought a gasket if I ever need one. NAPA # C-31349.

My 98 has a gasket, my 02 does not. The parts store will not have a listing for a gasket for the later model but the earlier gasket works fine on the later engines.

IIRC sometime around 99 they quit using a gasket for the tstat housing. Just the o-ring around the tstat was enough to seal it I guess. I've also never used a gasket on any L36/L67 cars and have had no problems with leaks if its properly torqued.
