Aftermarket throttle body gaskets garbage?

[forcefed86]

First off. what is the point of the passages in the rear of the TB if they are blocked off by the gasket?


Just got back from the parts store. I was expecting to see gaskets like these...

They tell me they don't carry the forward gasket. Only the base. Guy pulls them out and they look like cardboard and have none of the nice looking sealant going around the passages on the pic above.

They also cover up half the ISC passages on the lower back side of the TB. Should I trim the gasket?

I hate RTV with a passion. Just spend an hour cleaning it all off from previous owner. Is it necessary to use some sort of sealant again?

I can just cut my own FWD gasket I suppose.



Thanks

So the gasket in the picture is what they showed you or what you had on before?

You've done a good job of confusing me!

By "passages in the rear of the throttle body" I assume you're talking about the area the little raised holes cover? If so, they come from the inside of the throttle body and lead to the nipples on the top.

Then please try and explain your problem again, maybe using pictures if you can.

They will be fine. Those passages don't go through, I dunno what that gasket is doing with the stuff on it. All the passages go to inside the bore of the throttle body. All the gaskets I've used have been the cardboard-ish style.
