Check for posts and threads from smokey12 and ret9580. Smokey12 had his oil get in the air intake without the car being overfilled (museum delivery). Ret9850 had his overfilled multiple times by an incompetent dealership, and his leaked oil on his garage floor.

If your problem is the same as some other Z51 oil issues (IF it is the same root cause), then, yes, it is a known problem.

90% sure that's your issue. Also will guarantee the RX system will correct it. Your ingesting a ton of oil into your intake air charge and that is what causes the intake valve coking issues. Lot's of threads to read about the details, cause, effect, and cure.

Good luck!

A failed belt tensioner can also leave a puddle of oil like that. Did you happen to notice that the AC had quit working? In any case, hopefully they got you fixed up.

The AC worked but I did heard weird noise when I turn it up like something is losing pressure (air).

If your AC system had a failed line, the compressor should have de-energized. You might have heard the line fail, but that sound should have stopped after the compressor kicked out. I guess the real question is: Do you / will you hear any noise after it is fixed?

it wasnt a big leak. only when i blast the ac. i don't know how it works. they just told me it was not the oil. i check my oil and the color of the fluid that leak, could tell it was two diff fluids, just have to look closely. they seems really nice about it. i should get the car back either tonight or tomorrow...waiting on the part to come in. will find out soon enough. and yes the sounds did stop once started moving...i guess thats when the compressor starts...

If it was the AC it would be green fluid. My dealer told me the same BS the first time I had the oil leak. Listen to tuner boost.

yeah definitely thanks...did you have the exact same leak?
Yeah, he did, multiple times.

By the way, I see you are in Cali. What part are you in?

Very common with these....when you can dump oil out of the air intake assy your ingesting a ton of it and doing your motor no good:





The new Z06 has several updates that address the oil puking (burping) into the air intake bridge assy, but for you the only solution is to address it yourself by running lower on oil and installing the RX system that corrects this issue.

Lots of info here for you to read in several threads to understand it all.

Yep, continually overfilled by an incompetent service department, until I took it to a new dealer that got it right. By that time I had started California Lemon Law proceedings and was given a FULL refund of everything, including all my car payments to date.

Use the good dealer and not the other!! I believe all dealers servicing the Corvette should have at least one Corvette specific master tech on staff, but oil changes are done by the "Lube Techs", and that is generally the kids w/very little knowledge on this things, but every dealer is independently owned so blind trust is all most can put in the dealer they use w/out guidance from others like the members here that have done a good job of weeding out the bad, and praising the good.
