With the engine running,Take the PCV Valve out of it's hole, and put your thumb over the end of the valve. it should click & you should feel it pull. if not, clean the tube where it enters the Carb. If white smoke comes out of the valve cover while it's running, the compression rings are worn, and an overhaul is needed.

I commend you on having a still running 79 Fairmont!
Must be a neat experience to drive one of those in 2011. :smoke:

did it start these symptoms suddenly?

You can drill a small hole in "cap" of the dipstick, and the tube, and get a spring to keep the dipstick from coming out, thereby keeping more oil in the block....If that turns out to be the problem.

Check the PCV system even unto the plate under the carb which may be filled with crud.
Also, check your rubber fuel lines throughout the car to make sure the modern ethanol included fuels aren't eating them up.

The base plates on the 70's/80's cars were very bad about getting blocked with crud. I'd start looking at all the vacuum lines and the PCV lines on that thing and be ready to replace them all. There's a lot of vacuum assisted emission and stuff on that engine. Or there was from the factory.

Yeah, but like Andy says -- it's a driving miracle the thing survives! It will make a sweet ride and you will most likely be the only kid on the block with one! Let us know it's coming along...
