    This was out of a 6.2 DI truck I had. The C7 Z06 does this but did this picture just to prove a point about what does come out. Do not do this on my driveway lol..... All catch can systems are not the same.

      Thanks for posting that video.

      In addition to the obvious oil issue you mentioned, a high performance throttle body can be a nice performance upgrade for us "do it yourself" types.

        That oil vapor from the crankcase will, via the PCV system, end up in the intake is undeniable fact. That's what the PCV system is supposed to do. That the oil vapor will pass the backs of hot intake valves is indisputable. Each of us will have to decide whether that is a concern.

        On port fuel injected engines, the detergents in the gasoline will keep the valves clean. On direct injection engines, there's no fuel washing the backs of the valves. Some brands have had massive problems with carbon build up on the valves. I haven't seen anyone pull a high mileage LT1 or LT4 apart and check for deposits on the valves, so I don't know how much of an issue it will be long term. But there's no question there will be some deposits there.

        And I don't really buy the argument that "if it were a problem, GM would have added a catch can." Auto manufacturers are unlikely to add anything that adds a frequent maintenance requirement. For the last few decades the push has been to extend maintenance intervals as far as possible.

          I use the M&M catch can which works different and prevents the venting of crankcase fumes entering the intake or Supercharger. I drain it and it gets a A lot of oily condensation.
          it reroutes the venting from the block to the catch can instead of being in going in the engine. By far the best for your Corvette.

            Just why the M&M is the best mod for your Corvette stops the oil getting directly in the intake keeps it from the valves and from baking on the stems.
            I pulled my stock Supercharger on my 2015 Z06 in 2016 and the intercooler's were almost 1/2 plugged with gunk. All my Corvette get the M&M catch can as a very important mod.

              I agree a catch can is a useful addition. Not everyone agrees, and I'm way past getting into a debate about it. Everyone can make their own choices.

                Back in 2019, one of the reasons I bought my 2010 Camaro was the brand new 3.6L DOHC 24valve Direct Injection engine GM came out with. With all its positive attributes (having the injectors in the cylinders, as opposed to the intake manifold) I would soon learn there were some drawbacks. After less than 40,000. miles the car ran terrible, threw engine codes all the time and the fuel mileage was noticeably worse. I spent a fortune having multiple shops run their "intake cleaners" through that intake with no success. It wasn't until I went in there and manually cleaned every intake port/valve before the problem was solved. Wish I would have researched catch cans back then as well, but I didn't. I could show you pictures of all the oil I drained out of my newly installed catch can after the cleaning but other people in this thread have already shown you that. Instead, here are some before and after pictures I took of my intake ports/valves. Needless to say, I'm sold on catch cans for true DI engines.

                  MilesC8 Newbie here and don't know much about the catch can..... I know that the catch can Prevents Oil from Entering Intake. But what does that protect? What does it keep clean? I assume you ordered directly from the UPR website. What options did you order with it?

                    If you go back and read Meyerweb's post (# 48) he describes exactly what happens. The oil passing over the back of the intake valves get baked on from heat. It's a hard black carbon build up that is very difficult to clean. It slowly reduces the efficiency of air supplied to the cylinder to the point were eventually, the performance of the engine is adversely affected. Take a look at the valves in post #52 above. That engine is GM's 3.6L 24 valve DOHC. Corvettes LT2 is also a direct injection engine, and does has a PCV system that deposits oil into the intake, but how long this takes to happen, (if at all), in this engine, is not know to me.

                      The better ones also take out condensation... Been using catch cans for years. My C7 Z06 went from looking like an oil spill on the ranch when the SC cover was taken off to clean and dry after the can was added. Here is a picture of the inside of the SC before the can install after about 2k miles if memory serves. Note how clean the oil is.

                            Thank you for explaining it in English. I have had a super charged car for years and no one has ever called it an SC car.
