I'm Awesome
I'm going to be doing intake gaskets and some other work on my 1993 4.3 this coming weekend, but I'm wondering if I have the correct intake gaskets. I went with Felpro's but the rear coolant port is blocked off on them and on my truck the heater gets fed from the rear crossover passage in the intake, so I don't see how the heater will work with these gaskets. I just spend a good half hour up at my local NAPA after work today and they come up with the same exact gaskets as I did from Rock Auto. They did find that 1991 trucks used gaskets that have those rear ports open so I do have a pair of them coming just in case I need them. But I figured I'd ask the brain trust on here if anyone knows which style I need? The only oddball thing with my truck is that it was spec'd with California emissions when it was built so I have found a few odd things on it, such as even though it's a 93 it uses a heated 3 wire O2 sensor instead of the 49 state 1 wire style and also has an all electronic EGR valve instead of the 4 state vacuum operated one. So I'm not sure if that would make a difference for the intake gaskets too. I'm just trying to make sure I have all parts on hand so that I can get this job done.
