You should be able to go many thousands of miles before filling up your catch can. Something is not right. Rings?
Also, I deleted your duplicate thread. You couldn't see it because your first 2-posts require approval. It and other things are explained in the New Member area:
Thanks for the add Goose. I was hoping the second post would get deleted once I saw the post had to be approved. Rings and blow by could be a possibility. I was wondering if there were other ways for excessive oil to get sucked through the catch can like that. I was wondering if there could also be some type of vacuum issues or the PVC valve going gunny sack? Or if anyone else had experienced this and it not be rings.
Something is waaaay wrong. Try to get another similar year GT500 car nearby to compare engine compartments. Is it possible to have vacuum hoses routed/connected incorrectly to cause this...? I don't know the answer to that, but it's worth comparing.
Is the car otherwise running normally - as in no engine damage?
Wasn't on a GT500, but in high school my girlfriends Pinto had a PCV valve go bad. Started sucking so much oil into the intake the car looked like a mosquito fogger. If it had an oil separator it would have filled up very quickly.
I'd be checking the PCV valve.
Makes sense to me unless he's in boost a whole lot pulling the valve open. Otherwise there just shouldn't be any way for that volume of oil to get sucked up through the vent.
I'm hoping it's something simple like a PVC going out or something hooked up wrong. The separator is a JLT. It came pre-assembled. So there's not anything for men to screw up there. I really haven't noticed a difference in mileage either. But that may be due to I try and keep it emptied.
From your pics, I noticed the problem right off...your car is upside down...>I'm curious to the problem, waiting on results, hope it is something simple.
Also,.I'm not in boost all that often. This is after regular driving. Been kinda scared to push it until I get this figured out. So maybe a few pounds when pulling a grade but nothing out of the ordinary.
Well that's interesting. Thanks Snoopy. Because I took it off to look at it a couple of days ago (the issue has been happening all summer). All I had to do was remove the bolts. I didn't have to twist it to remove it. And it came right off So, now I'm thinking it was either removed by the previous owners or when I had the cams installed.
When you removed the PCV valve, you also removed the twist lock mount/adapter that is screwed down. The PCV valve is damaged when you untwist it from the screw in mount.

Looks like you should always remove the screwed-down mount/adapter BEFORE removing the PCV valve, otherwise the sheared off plastic retaining 'ears' fall down into the valve cover??? :shrug03:
I wonder how shearing the valve's retaining ears would cause the valve to let the OP's situation occur. I get the retaining ears are needed to keep the valve in position, but pcv valves I'm familiar with are basically a weighted check valve that is lifted when vacuum or crankcase pressure is enough to lift the weight.
Someone asked about mods earlier. It's cammed. When the cams were installed, they also R&Red the vacuum booster with an aftermarket one. I wonder if the vacuum boost went gunny sack, if that could cause part of the problem too? It mounts to the back of the supercharger right below the elbow.
Very possible! Trouble with these damned modern cars is everything seems inner dependent of something else! You remove the gas cap and the heater stops working LOL! Let us know how thing work out. As Tim mentioned, you might find that your inner cooler is plugged up with oil, as well. I know, just what you wanted to hear!
Another suggestion I had for checking to see if it is vacuum related is to disconnect the line from the supercharger. cap the inlet where the hose hooks up to the S/C. Then, run an extended down the side of the engine from the PCV valve. The crankcase should still vent. Take it for a drive and see if it still pukes out a bunch of oil. If it doesn't, I'm thinking it's still a vacuum problem. If it's still digesting oil, then it's not a vacuum issue. Pretty low tech for sure. But here's why I'm considering it.
While looking things over, I disconnected the line from the PCV-S/C at the pcv valve. The car ran like crap, as it should. I plugged the line and the car smoothed right out, as it should. When I reconnect the line back to the PCV valve, the car started running better. However, it still did not run as smoothly as when the line was plugged. That kind of indicates to me, the car acts like there is still a vacuum leak or other issue with the vacuum. Thoughts?

Here's an update guys. I changed the PCV valve and nothing changed. So, I unbolted the PCV mount, plugged the line to the S/C, and started the car. At idle, nothing appeared out of the ordinary. Give the car a little throttle however, and things started to happen. Mainly, a broken stream of oil would come over the baffle right to where the PCV was mounted. The stream was not from 90 degrees to the PCV valve either, but coming at an angle from the front of the engine. Pulled the valve cover. The bolts in the inboard, forward cam tower were loose. They hadn't backed off very far thankfully. The cam tower and cap looked to in good condition as well. Re-torqued the bolts, and rechecked the torque on all the other bolts on all the cam towers on both cams. There were no other bolts that had worked loose. Put it all back together. Performed the same check as above, no oil squirting over the baffle. Took the car for a test drive, no new oil in the separator. Might be a good idea to keep this little issue filed away for the future. Particularly if your car has been cammed.
Good update......thanks for the follow-up! Sounds like someone took a lunch break and forgot to torque the last two cam bolts!!:surprise: Glad you were able to find it and correct it before any major damage was done! Great detective work!
