OK, final update and here is what I did. Drained old oil, put in a gallon of diesel, ran the engine for three minutes. Drained the diesel and replaced with used oil from my wife's car. Ran for 3 minutes and then drained. Put in new 30 wt. Also cleaned the breather cap and pcv valve. Let it sit for 2 hours and started it up. Had 40 psi at idle. Let it run 10 minutes and pressure dropped to 32 at idle. Will build up to just under 40 at higher rpm. Blowby was much improved. I'm satisfied for now if I don't run it hard things will be ok for a while. Now it's on to the body. Thanks everybody for your input.
