I did a search and couldn't find a pic for the arv on a 85 300d. From what I read I don't think all 300's had them, but I read that all 85's do. Can someone please me in the right direction so I can disable it. Curious to see the difference with the egr and arv disconnected.

If you have one, it is nestled right on the turbo........and it has a vacuum hose that is connected to it.

Don't confuse this with the wastegate which has a larger fuel hose attached to it and it typically located beneath the turbo.
