Default EGR Fuel Rail Valve Question

Will any series I, II, III, EGR valves fit a Vin "C" ?

Is the Schrader valve on the fuel rail replacable and if so will a regular tire valve stem work?

Thanks

No, series I up to '94 got a digital EGR 94+ got a linear

IIRC The schrader valve is actually part of the fuel rail. I guess if you're really motivated you could find a way to replace it but a new fuel rail would probably be easier. Its also larger than a tire valve.

There was a brief period (think 1992) where the "L" engine had no EGR. "C" engines all have the triple solenoid "digital" EGR. The AC-Delco part number is 214-5004 and there were 262 car models that used it through 1995 (for a comple list go to http://198.208.187.182/internet/VehiclePartFits.jsp and enter the part number).

As to the schrader valve, the cap is an integral part of the seal and the proper one has an o-ring in the top. The one on our 88 "C" is smaller than on the 90.

Padgett is right.. the LN3 [88-91] got the three solenoid EGR valve. The LG3 [87-early88] had a manual EGR valve.. that I really don't understand how it worked.. but I know it wasn't electronic. The schrader valve is not going to be replaceable on the fuel rail.. I really don't know how you could even break one!

The schrader valve leaked (seeped may be the word for it) after I removed my fuel pressure gauge. Have you ever had a valve stem leak on your tire? I thought it might be replacable.

Thanks

Had the valve on a V-6 Fiero seep slightly after removing the guage. With the proper cap on it didn't.
