And it's BACK AGAIN!!!! by screamin_conure on 2011/10/19 22:47:56 I know your car has a few miles on it, so if that EGR valve is original, it's probably time for a change. Just a tip: When I did mine last year, I found the job was made MUCH easier by just going ahead and pulling the fuel rails up as if you were going to swap injectors. The very back of the fuel rails on an LT1 get in the way of accessing the two bolts that hold the EGR in place. You'll be able to get the one closest to you off, but that second one that sits lower is a bitch with the rails in place. It sounds like a lot of extra work, but the time and frustration you'll save trying to get at that second bolt will be worth it. Just remove the rails and carefully lay them back on the windshield. The EGR will be a piece of cake to get to now. |
