Brand new owner of a '74 2.0L with the original D-Jet in place. Until now I've built and raced Type I based VW Beetles, so I'm on a bit of an accelerated learning curve.

I purchased the car with the understanding it probably needed a top end rebuild. When you drove it it would leave a cloud behind it like none I've ever seen. Oil was litterally dripping out of the tail pipe. Yes, drops of oil.

Once I got it home I found that the crankcase was insanely over filled. Oil was half way up the dip stick. This gave me hope of avoiding a top end rebuild. I drained and correctly refilled the oil, cleaned about 3 quarts of muck off the bottom of the car, and set the timing as best I could without verifying TDC.

Now it doesn't smoke at all when cold, but still smokes moderatley while driving. It does NOT smoke on decel. There are a few other interesting observations.

1. It doesn't idle well when warm, yet idles very nicely when cold.
2. The plugs are black with carbon, but not wet with oil. The carbon build up is somewhat chunky and all 4 plugs are the same.
3. Power is good on the car, but that's a bit subjective as this is my first and only 914 and I'm use to a 160HP '66 Bug.

I'm planning on replacing the PCV valve and checking other routine maintenance things. Any other ideas on the smoke other than a top end rebuild?

Thanks.
