EGR valve for a 1980 D 50

[Goskate000]

Mine has a secondary bypass is there anyway I can use one from the later models without it and run the vacuum line to another location?

[Salteen]

just cut it out it'll run so much better. and weber swap it.

[Salteen]

there is also a adapter plate you can use as well but honestly just stick a cap on it or put a bolt in the hose or a screw or a nail if you're that anal about the factory equipment stuff

[Goskate000]

I have to pass ca emissions. It usually passes easy I just want a new one

Check ebay and visually compare what vendors have on offer - be warned, some of the prices are 'optimistic'

there is one on Ebay for the 2.4, but it may not work and doesn't look like the dual vacuum one you need for California...

I may have one off a 79' somewhere in my parts I saved. its worth noting that the EGR valves are weird on these trucks in that there are two different size mounting patterns that look identical in pictures when looking for a gasket but they are different sizes, I went to buy a gasket for my 87' 2.6l and the gasket looked identical on the screen but when I got the gasket it was shrunken down in size so I had to use a different gasket possibly from an older truck but I can't say for sure now

No way if you do I will deffinately buy it! And mine the passages in the egr are eaten away like something sat in there like seafoam and chewed the metal

the 2.0 EGR is smaller than the 2.6 EGR - that may be the issue with the different gaskets.
