I would like to share something with every one. I was chasing codes on my 1994 S10 Blazer vin w 4.3 vortec pouring over wiring and replacing one part after another, nothing happened but me getting raging mad. So I went out and bout a wrecked vehicle for parts. I had decided to swap engines, I made sure the on im putting runs, and it does so like a kitten.
So i started to pull out the ening im going to replce, and decided to pull off both intakes... I found some one had re used the old head gaskets, lower intake gaskets and didnt even bother putting on any valve cover gaskets. Even though i dont know who did this to save your self some, time and maybe even money please do not re-use any old gasket doing so usually results in labor intensive repair and possibly ruining a good engine. th bad thing no one should ever have to type or say that.....
