Trying to free sticking oil control rings in my ZHP

[Smolck]

Bump. Any updates ?

Yea, sorry I forgot about this thread. Sort of chronicling this in my catch can thread too.

As of 10 minutes ago, I have driven 940 miles since topping off. I have used ZERO oil. Dipstick says it is still full. Just amazing. I had done an oil change about 6000 miles ago with Mobil 1 0w40. I then changed my filter at 2500 miles. Then after using a couple qts I started using Penzoil Euro 5w40 (ferrari emblem on the bottle) and have put 3 qts in it. Since the third was added no oil has been used. I am about due for a change and will be going 100% Penzoil. Interested to see what that does.

I suspected some of my oil was departing via failed CCV, but the old CCV wasn't obviously broken or failing, though I haven't pried it open to see if the diaphragm is okay. There is something dripping oil down the bottom of the oil pan, most likely oil pan gasket. Could be front or rear main seal, but gasket seems most likely.

More likely the oil filter housing gasket

Possibly, but the upper part of my engine block left-side waffle area is dry, and I replaced the OFHG 4 years ago. Guess it could be leaking again--need to take out alternator some time and take a good look at it.
