Feels great! Finally have an answer to the C7 oiling issue!

This is a HUGE ISSUE!
Plenty of people have PM'd me. I try to answer
all of them. After talking with 2 experienced Corvette shops.
The possible barfing Dry sump is a defect in the lt1 design. GM didn't do enough work.
Then the second issue developed from my tune and the oiling compounded my problem. So now i need a top end clening and a new tune.

Update. I have fixed the dry sump issue. That issue seems case closed but another issue after driving 20 miles oil came out the valve cover lines that were rerouted.

Which attachs thought the PVC line to the intake.
Someone invented the fix and even tryed contacting GM about the design problem.
A shop which pulls alot of intakes told me about Z51 every they see has oil in the bellow.
Sorry your so out of the loup and have no idea. But come to start trouble.
I got some helpfrom some one who knows exactly of the problems of the Lt1.
My car is back in order. It no longer can get oil in the intake. Supercharger shops all of them have had and looked at the issue. Which can present on any Z51!

Ah, so a fix is out for what? Z51s seem to be the only models significantly affected by oil in the throttle body area, a problem considerably reduced by filling to proper oil levels.
Haven’t heard of base models having any issue. I know my base C7 has zero issues with oil in the intake stream.
So, GM is dumb for making cars that weren’t intended to be supercharged free from problems? If you want factory coverage on a supercharged car, buy a 2015 ZO6. If not, be prepared to deal with any issues that come up.
If this is such a great revelation, share it with all of us, not by PM. Don

infront of the air box. This amount can vary greatly and is not know till it comes out from too much. Or is never looked at.
Which comes from the vent that is tied with a line venting to the air intake since GM cannot vent to atmosphere.
Not sure on the base car. I don't have one. This is on the Z51's
with the dry sump. This dry sump can puch oil it to the intake via the line discussed. The dry sump system has two pumps which I was told has two different rates and can catch air and cause oil to head for the intake along with any over filling makes it worse which varies because levels vary.
Because of checking procedure and temp. 2 things to get a bad check.
The inventor helped me wants low key and I want to help with out.
advertisting.
The 20 people wanting help from PM's and all the other posts here and a GM service bulletin says it can be a issue.
The Z51 has more ways for oil to come in the intake air tract also!
