When you say pressure appears high, what happens when you remove the cap? Oil spitting out, the sound of z "heavy breathing"?
You say PCV is fine, I gather it shows suction when removed while the engine is running. So put it back.
With the engine idling, remove the oil cap and block off the opening with yout hand. Do you feel pressure then, or suction? Or neither? I think I would expect either neither, or slight ****. In which case, all is good.

Oil light comes on under deceleration.oil levels are fine


I would guess your oil pump is going out causing it to loose oil pressure. If you continue to drive your car in this condition it will most likely ruin the engine. If it is not your oil pump it is something else causing you to loose oil pressure and I would have it looked at soon.

00 ford focus wagon a/c & engine smoke problem


Engine smoke problem-- Automatic, chk transmodulator. If oil in vacuum line, modulator is defective. Engine sucking up trans fluid. 10.00 fix . good indicator is smoking at cruising speed or deceleration.
Bad rings smoke under acceleration and bad valve guides smoke on deceleration. poor crankcase ventilation (pcv valve) will cause engine leaks and oil blowing out of dipstick. Good Luck

Oil pressure high when engine cold. but fine when engine is warm


It is normal for oil pressure to be higher when the oil is cold. As the oil heats up, it will thin out. Since your oil pump is driven faster with the acceleration of the engine, your pressure will also increase. On a engine up to full temp, your oil pressure will probably be around 20 psi and maybe up to 60 at full load. But on a cold engine, you may see 60 psi at idle. I dont know if your high oil pressure is causing your vehicle to stall, but maybe your running the wrong weight/type of oil for your truck. If you live in a extreme cold area, you may want to look into a block heater to help warm up your engine faster.

Engine smokes blue white right side only


I'm going to guess it's a blocked oil return in the head under the valve cover. If it fills up the rocker cover, the valve seals can't handle that much oil and it gets into the combustion system. Try looking through an opening, oil cap, PCV valve opening to see if a lot of oil is pooling up.

Otherwise, it could be the PCV valve if causing pressure in the rocker cover. Or valve stem seals if it's worse on acceleration after coasting down. Good luck
