Default TPI runner gaskets

TPI runner gaskets, do you guys install them dry, or with gasket adhesive, or anything special? I'm talking about the upper and lower gaskets on the runners.

Grease film.

You try to get a good seal by over-torqueing, and you're gonna' strip hole in that 20 year old aluminum.

Vacuum leaks on L98 are a plague.

I heard of using wheel bearing grease to prevent vacumme leaks. Just spread grease all over the gaskets and mating surfaces, and bolt it back together.. I figured gasket adhesive would work as well.

my motor with 100,000 miles, I already spent 10 hours scraping gaskets, and I did gouge the aluminum more than once, that's why I'm concerned about vacumme leaks.....

any problems with installing them dry ????

In the future,get 6+ inch bench grinder...put a good wire wheel on one end and use that to clean the gaskets off your parts.It wont gouge the metal like a hand held scraper can.

That bench grinder will work real well on the intake manifold - runner surface

for now I'll use a single edge razor blade.

I'm sure there's no problems right after install, putting gaskets in with a thin film of grease, and I think you'll better accommodate the 'flex' that L98 has in its components, and thereby retain the 'seal'.

Suggest you use Fel Pro gaskets and put 'em in dry. The Fel Pro runner gaskets have some positioning pins built into the gaskets that really help align the parts during assembly.

Scotch Brite disk on a drill will knock off old gasket material without hurting the metal in a flash. Replace them dry.
