5.7l TBI valve seal replacement

[Keepinitoldskool]

i usually go with the standard stock replacement intake ones and for the exhaust i do the high temp ones, every set of tbi heads ive pulled apart regardless of stock or rebuilt the stock or stock replacement valve seasl are either throtoughly melted, completely destroed or just plain out not there anymore

So should I be looking for nitrile ones?

As Im looking to order these im not seeing my motor as a application. Are all sbc valave seals the same pre vortecs?

 

[TylerZ281500]

i believe so, theyve worked on everything ive used em on before, 882/113/416/083/tbi heads ive all done with those unless ive missed something but the engines are still going strong not burning anything.

Ok thanks. I will see if I can order them tonight.

Ordered a set of the ss72877 and a set of intake seals into a local autozone and picked them up today. Looking to install them tomorrow provided weather is nice.

Anyone have any tips for getting the keepers off? Spring compressors just keeps pulling the bottom of the spring up and not letting tension off the keepers.

I've heard if you use a socket and put it on the top of the spring then tap it a few times it helps.

Yeah I tried that too. I finally found a method that works, its just difficult to get tne compressor to stay on. It doesnt fit very well.

Worse than I thought. There was no sign of a exhaust valve seal on cylinder 1.
