Need to get a one way check valve on the driver side tube but no stores have what I need. What's the part number that u used and do u have pics of how and where u installed it?

Thanks

My '00 has a check valve on the driver side valve cover from the factory. Maybe try looking it up for a 99-02 truck or see if you can find the valve cover from one.

I guess it's a PCV valve that also functions as a check valve and fits in the stock spot on the driver side valve cover. I guess the stock PCV valve will still let a small amount of air through the opposite direction.

Or you can run the stock PCV valve with an inline check valve. I don't know where to get one though. A search on here or LS1tech would probably help.

auto zone sells inline pcv valve that works as a check valve. they are usually around the air filters.

Just go to the GM dealer and get part number 20861501. It's part of a recall so they stock it and it fits perfect!

Any benefit to using this one rather than something than some generic one at Autozone?
