Oil drenched air filter.

[CucvFML]

85 m1009 25k miles daily driver. Lately its been throwing clouds of smoke during any acceleration, and my air filter is covered with oil. Any ideas on what the problem might be?

Check the hoses and connections on the CDR valve.

I don't suppose you know of a source for them?

Autozone... oriley.... napa....a civy part. you will have to go in to the Stant (sp?) book. It will NOT list it under trucks. I think i found it under olds diesels.... but get the buyers guide and look its in there! like 15 bucks tops.

The CDR valve is most likely clogged or damaged preventing the spring and diaphragm from working properly. It will dump excessive blow by gases and oil into the intake. It can be cleaned or replaced. Replacing it is a better option.

Ok, thanks. I was under the impression that it was NOT the same as the civy version, as I've read posts here where the civy one is just a cap, not a breather, due to emission controls, etc.

you are correct the trucks are listed with a cap... thats why i said look for it in the book or under olds... i think.... the replacement is there...

There is really no need to replace the cap. It can be cleaned with degreaser spray and water or brakecleen. After cleaning, shake the cap, if it rattles it's good to go, if not then clean it again. Let it dry naturally after cleaning.
