Hello, I was wondering if anyone would be able to tell me the factory EGR valve ID number or which size (number) washer should be used when installing a replacement EGR valve? The engine is the Oldsmobile 307 VIN "Y" and the car is a 1985 Oldsmobile Toronado Caliente. The original EGR valve is not available and there is no documentation as to what is suppose to be used, if anything. Thanks in advance for your help!
