72 Dart 360 PVC valve issues
If the car had been sitting for a long time, then you need to reseat the rings.
They get carboned up and don't push out to the cylinder walls to seal like they are supposed to. 1 pint of seafoam in the oil take it out and run it, then let the car sit for a week so the sea foam can do it's job loosening up the rings.
Then fire it up, warm it up and then change out the oil and filter using 5w 30 (thin is key), then take it out and run it good to heat it up for about an hour. Then change out the oil and filter again and go back to your regular oil 10w 30 and rings should start sealing better by now and problems go away.
If you really want to attach the carbon around the rings, pull all the plugs and put 1 oz of seafoam in each cylinder and let it sit for a week. Your oil will turn paint black after doing this. Then go though the routine above changing out to the thin oil etc....
Have saved many an engine by doing this and have gotten them to burn clean by cleaning the carbon from the rings with seafoam, then they are able to expand out again and wear into the cylinder walls again to make a good seal. Diesel engine too, no more smoke out the exhaust.
Here is proof this works, this truck sat in a pasture for 6 years outside, has 96,000 miles on it. When it first started up it smoked... pretty bad. Did the seafoam down the spark plug holes and let it set, multiple oil changes back to back over a 2 week period.
Running nice and strong now and no more smoke out the tailpipe, rings are seated again. Proof's in the pudding.
Yes it's my custom built ignition.
If your PCV is rattling, back down your timing and it will take car of that too. Ask me how I know.....
