91 c1500 2 wheel drive 350 mileage 215535
need to find out which orifice washer to use when you don't have the o.E. Part number to go by.
the staff at the parts store that I bought the new egr valve at could not help me to find the right orifice washer. The paper work that came with the egr valve did not have the washer number from the old egr on the selection chart. Not even sure the egr I took off was the correct egr valve for this truck. Not sure if it is a good idea to use same washer number for new egr.
have the same problem?
