I would think 20w50 would tend to help with the issues described, not make it worse. You must have some other stuff going on.

Sorry, was first post in the morning and confused with another guy using a e-carb.

That is what I thought as well and I think I went to the 20W50 as my though has always been that thicker is better but I'm not sold on that.

With the remnants of Lee here right now, the car will not be moving for a day or two.

Like I said, typically when you have blowby with oil pushing up through the PCV and crank case vent, it's a ring sealing issue. Not always, but typically. A leak down will give you a better idea.

If that's the case, it's really not a minor rebuild either. Short block will have to come apart. At a minimum a hone and re-ring will be needed and when I have them down that far it's steam rolls into just doing the whole engine and gets expensive quickly. If it has a bunch of miles I almost always find cylinders out of round, an overbore needed, new pistons.........you get the idea.

Very good advice here, my car did the same only smoked under heavy accel, ended up with a re-ring and a hone............and a few other things, adds up quick..............running good now.

Was finally able to put some time into the car.

Oil is now 10W30 and the cooling system is functioning like it should.

I put in a new PCV valve (just in case) and added the Restore. I know it takes a while to work so no report on that, yet.

The car was leaking oil under hard acceleration and I narrowed it down to the oil filter leaking so I was able to get under there and tighten it a bit more; it is not leaking now.

Now, under hard acceleration, the dip stick is popping out just enough to spew oil on the headers and head. So, that speaks to the issue that everyone has mentioned here already about the rings or valve stem o-rings.

I'm going to drive it a bit to see if the Restore does anything and hope I did not waste my money.

Poor valve stem O rings will not make for the condition of pushing the dip stick out, your barking up the wrong tree with that one.

That's crank case pressure pushing the dipstick out and usually a bad sign that ring seal has gone away.
