Thread: Lower Intake Gaskets

Felpro Part No. MS98014T........Also do the thermostat,it's $5 and it has to come out anyways

Thermostat gasket? I replaced my thermostat about a month ago. I didnt see an existing gasket so I didnt put one in also.. Unless that Rubber O ring is considered the gasket.

No I didn't mean the gasket I just meant the thermostat, but if you already did it then nevermind.

You don't need a gasket...just the rubber O-Ring.

Hold up.. Erich..why does the T stat have to come out for LIM gaskets? I never take it out, it's extra work for no reason.

I've seen the Fel Pro gaskets and prefer the GM aluminum gaskets. Both should work fine, just a personal preference.

Coolant elbows
Teflon paste (LIM bolts)
Brake cleaner (gasket surfaces)
Gasket scrapers
Ultra copper RTV (LIM corners)
TB gasket
TB cleaner (You gotta clean it)
SC to LIM gasket (aka listed as plenum gasket)

You're right it doesn't HAVE to, but there's not really a reason not to do it at that time if it hasn't been done before.

Ain't broke, don't need to be replaced...it's a few extra minutes.

I bet if I skipped mine it would have gotten stuck open the next day
