I am sorry to hear of the discontent you have with your vehicle. If you could please send me the details about the concern you are having, I would be more than happy to see if there are any options available to you.

The statement highlighted in red "oil leaked past the main seal in both motors at high RPM" Both motors? So was there another documented case of the same issue? I want to check this grommet on day one when I take delivery. Would love to see the part in a picture or a part number. I guess if you see light thru it, it should be good ya? Thanx again..

My ZL1 was in the shop numerous times before they finally did a motor swap, that's where the second motor comes in. Engineers were contacted when the problem re-occured. They explained the grommet was never replaced, as it isn't part of the engine. I would've posted pictures, but GM wanted the old motor, as well as the mis-punched grommet returned.

Can you post a picture where the grommet is located on your current ZL1 ? Thank you.

Schtuff happens, but GM came through for you, AND we all know what caused the problem.

Sorry you had all that grief, but I'm glad it's resolved now. Enjoy the ride. =D

If I interpret your post correctly you don't think I had a very severe issue. I ran through the whole ordeal step by step in the forum titled "Serious ZL1 Defects." Including pictured as seen on this page

http://www.camaro5.com/forums/showthread.php?t=236658

Oil purging at high engine RPM's on the underside of the car including scoring on the exhaust and flywheel, repeated attempts at a repair to no avail including a crate motor swap, finally found to be a mis-manufactured rubber grommet in the PCV system where it vents into the intake manifold. Of all of the issues posted to this forum I don't think I have been acting like chicken little.

I read your post through and through, thanks for your concern about my post!. I wanted to find out exactly what was the issue since this became a major thread of mechanical concern that you posted on. You mentioned a grommet as I recall without any specific location, system function, or repair method. Just looking for clarification since so much passion was put into the post by the OP, and to enlighten us all if it becomes a point of contention for us ZL1 owners down the road. Any attempt of an explaination was vague and unclear at best.

I'm not trying to be rude at all but the explanation was very clear.

Location: Between a metal can of the PCV system and the intake manifold. Two PCV lines connect to this can, and at periods of high engine pressure vent excess back into the intake to prevent a blowout. I asked if this can was what I think of as an oil separator but the service manager wasn't able to confirm. If someone here knows more about the ZL1 PCV system feel free to fill me in as-well as anyone else who wants a more in-depth explanation.

Occurrence: High engine RPM's as experienced by aggressive driving.

Function: As I understand it, merely a pass-through of excess pressure between this can and the intake.

Repair Method: After confirming for the second time none of the PCV lines themselves were blocked, this can was inspected. The service tech attempted to blow air through the can and a blockage was confirmed. The center portion of this grommet was not completely cleared, so the service manager said he literally just peeled it away with his finger. He brought it with him when he dropped the car back off to me and I would say it was a dime sized piece of thin rubber. It apparently was able to hold back the several PSI that was enough to cause a seal to leak elsewhere in the motor however.
