At idle I'm getting grey smoke out of tail pipe. What would cause this?

Replaced it less than 6000 miles ago

Just because you replaced it doesn't mean it's not faulty, clogged or stuck. Or has the incorrect spring tension. Is the pipe oily between the valve and Manifold? If you remove the pipe and plug it to prevent vacuum leak, does the smoke stop?

Have not tried that. Will though and report back. Thanks.

Did you use the correct PCV valve? Many PCV valves appear outwardly identical, but they are not interchangeable.

I would also suggest wet & dry compression tests.

Tried the pcv valve delete. Still getting the smoke.

Grab the SQ series Service Manuals from the FAQ thread for the specs. Then with a fully charged battery, open throttle, all plugs removed and preferably a warm engine...crank away.

You can Google the procedure for video details if needed. Or if conducting a leak-down test instead the details surrounding the procedure.
