Ever try to buy and install an EGR valve for the 2.8? What's with all the sets of numbers you're supposed to cross-reference? (That is supposed to be on top of your original EGR) The EGR on my 86 GT is not original and has no number on top. So, I simply picked the more commonly ordered one and ordered it through Rock Auto. The AC Delco p/n is 214-1415. Is this the correct one?
My second question is that inside the box there is a whole bag of numbered "orifice holed" washers. You're supposed to pick the correct one based on the supposed number on top of your EGR valve and then "peen" it to the small hole in the bottom of the EGR valve.
Can someone help? What EGR and orifice washer did you use on your 2.8?
Note: If it matters my engine is actually an 88 cause the water pump bolts are Allen head. Oh, and I also just installed a Calif "OE" certified cat.
