Bought this car for $500 non-running. Got it running and it smokes James Bond style. It burns oil (about 1/2qt per tank of gas) and nothing I’ve tried has fixed it.
The Z has 149k miles and sat for about 6yr before I got it.

Here’s what I’ve done.

1. Changed the PCV. The old one didn't look any dirtier than expected.

2. Ran the car for 45min @1500-1800RPM with 1qt ATF.

3. Checked in on the car, it had a CEL, and a blinking airbag light. Ran the codes and they came up as a "random misfire" (I've had that one on this car in the past) and a "battery voltage abnormal". Cleared the codes but the airbag light still blinks.

4. Used Marvels Mystery to top off the oil the car had burned (little less than half a QT) and ran it for another 45min @1500-1800RPM.

5. After the second 45min session had concluded, I ran it up the road a bit spiritedly to see if it would clear out anything but when I got back to the house, it still smoked pretty badly.

6. Did another oil change to get the ATF out, and it still smokes.

7. Did a sea foam treatment (through the intake) to no avail.

I’ve talked to a few buddies about this and we’re thinking it’s internal. I’m curious if y’all have any other suggestions.

What's the compression

RumbleSkittle

Not sure yet. This evening’s plans are to do a compression test and if that doesn’t yield any results, I’m going to get a leak-down tester and begin running that test.
