simple tpi assembly question

hey all,

I have had my tpi assembly put together for almost a whole week (yaay me ). now i need to tear it back down due to crap injectors. do i really need to order new gaskets (large diameter) or can i get away with using them again? maybe a little of that high tack stuff to help the seal?

Thanks,

Thunder

I agree. Get new gaskets. I did the same thing with mine. If I remember, Advanced sells an entire set of Felpro gaskets for around $40. Also make sure you check and carefully cut out any areas with excess material. It could restrict air flow and we all hate that. Good luck.

Re: simple tpi assembly question

damn. thats a freakin bummer. i gasket matched the damn things... guess i learned my lesson. test the injectors FIRST.

does anyone have an easy way to open the gaskets up?? i have a felpro set, and i have an edlebrock set, both of which are metal impregnated. this of course makes them a bitch to modify. a dremel sanding wheel just gets chewed/cut up, and using a deburring tool just jerks it out of your hand. my ports are all opened up to 1.75, which requires alot of modification to the standard gaskets

Re: simple tpi assembly question

Maybe try the carbide dremel tool. It's made of metal and looks similar to a roto-zip bit. It won't get clogged up or beat up like the sanding ones. I haven't used it on a metal impregnated gasket but I have used them on solid metal and they work great. Should go through a gasket like a hot knife through butter. Good luck.

Re: simple tpi assembly question

not with the edelbrock runners... they are larger and hold the fuel rail much tighter than the stock runners. if you have a trick to do this, please hook me up... that would make my life suck much less right now

I just used the drill and a 6 inch "light rust and paint remover pad" combined with a sharp scrapper, removes the old gasket material off the runners pretty quick and then it's on to polishing the runners....good luck
