My last effort

Yes..The 2 oily plugs are on the passenger side last 2(nearest radiator)..Just out of curiosity,,how much of a b1tch is it to get the cam covers off?It looks like a pain..I'd love to see what those filters look like,that is if there's anything left..I pulled those pipes with the car running..They had no vac or pressure in either direction..Don't know if that is significant..

You should feel something if you rev the engine.
Use the cruise control vacuum actuator just above the battery to rev.

So #2 and 4. Both of which bracket the oil vent. Just interesting and coincidental? The passenger side cam cover is the easier of the two to remove.
It so happens, I took mine off a few years ago chasing an oil leak and a smell of oil when I would go WOT. ANYTHING BELOW THAT was no issue. I replaced the oil vent filter, which was Scotchbrite, w filters from Marc Haibeck. You may want to check the spark plug cam cover seals also. Once I did that, oil smell at WOT went away and no more oil spotting.

Im sorry to hear of this terrible problem. If my car had this problem I would be frantic and depressed so lets show some compassion for this man and not ask about his wheels yet. He hasnt sold the car yet and he probably doesnt want too but depending on the engine trouble he might have too. I have nothing to offer as far as knowledge on this one only that by the youtube video it is not normal at all. I would probably take it to Mr. Haibeck or Aaron Scott to check things out. Maybe it is an inexpensive fix?? Good luck my friend.

If you can see it, notice the throttle cover is removed when I'm manually revving the engine..I removed it for easier access when checking for vac under throttle..I did pull the passenger side cam tube(tube on top of where filter resides)There was no vac there at all..I pulled off all PCV plumbing piece by piece..Can't find any obstructions..Plenum was also just off to remove secondaries..Not a single trace of oil around breather box or anywhere else in the valley..Can't say the same for the plenum..Oil was present but not anything I didn't expect from reading on here..Only my threads make it to page 4 in one day lol...

Typically, if valve seals are bad you get a lot of smoke at start up after sitting a while, like overnight. After start up, smoke decreases. Bad rings will show smoke increase as you get on it. If compression is good and you aren't getting a ton of smoke at start up which clears up somewhat after warning up, I would be looking at the crankcase ventilation, maybe even adding a catch can if that is possible on these engines. Adding a catch can will keep oil from entering the intake and then if you are still blowing smoke you know it is a more serious engine issue.

maybe it needs an Italian tune up? Sitting around and being idled in the cold all Winter isnt helping. I would go burn off all that Winter buildup abd get the engine hot an see how it behaves then.
It would be nice to watch the tailpipes during a WOT acceleration pass from an other car. following the Z.

Leakdown test could be beneficial. Proper compression tester technique will determine if rings or valves are an issue. Dry 1st, then wet.

I see in another thread you recently replaced the PCV Valves (CV913C & CV769C)....so this may be a non issue

What is the history of this oil burning issue??
Sounds like this oil burning issue did not progress over a driving period of say 50K miles but over a driving period of a few hundred miles or less and if that is the case.....you can eliminate all sorts of potential mechanical issues.

Plenty of suction present at the PCV valves is not an indication of a properly working PCV system

I have no technical answers for you here - but I do know that Marc Haibeck works late in the evenings. As in like into the night. I would suggest maybe e-mailing the link to the thread/threads to him - and then giving him a call later in the evening. zr1specialist.com

After rereading through all this suggest checking your injector housing gaskets. I think you may find a crack in the gasket or perhaps they are not tight. Either way thats my final "Easy" thought on oil consumption. GC
