This is why I installed a catch can
This is exactly why I have Oil Catch Cans installed in both my GDI engine cars, my C7 Corvette and my Optima.
Video was taken and provided by Bobby Likis Car Clinic. Video shows the intake side of a Jaguar GDI engine which experienced lost horsepower and air choking due to carbon build up in the intake manifold and on the intake valves.

Had 140k on my last GDI car with no issues. This topics been beaten to death. Nothing against you and your thoughts but Lots of c7 s with plenty of miles and no issues. Spend my money elsewhere.

Unsure what the relevence of a POS Jaguar on this forum is unless your assertion a C7 will look similar...which there is no evidence yet provided.
It almost seems like Catch Cans generate a cult like following.
Please cue the usual actors.

A little surprised at your ignorant comments. Given the fact GDI engine have fuel injectors inside the combustion chamber and no fuel cleaning intake values has NOTHING to do with brands it's a drawback of the GDI technology. That's the relevance...DUH.

Thanks Maxie. I use them on my cars, but it's a taboo subject here. That video is "some guy". Every time I empty mine, I see why I installed them first hand. But not going to get any easier talking about it around here. Might as well just close the thread and save your time

How many miles does that engine in the video have on it? Most C7s are garage queens that get, at most, a few thousand miles a year. It’ll take decades to get that kind of buildup on a garage queen.

Now, now, don't tell the nay-sayers that!
They've commuted and driven to coffee & cars (when the streets are not wet) for tens of thousands of miles with no issues whatsoever.
Money is much better spent on underhood dressings & Zaino!
Beside, these things could void your warranty!

Let's see, $70K car and $150 catch can.
It's worth it just for peace of mind.
Put mine in 1st week I had it.

Let's see . . . not a single study I've found has implicated oil ingestion as a significant cause of valve coking in GDI engines. It's a function of all aspects of combustion, 99.99% of which is just pure gasoline. The OP picture would look fundamentally the same after the same mileage with a catch can.
It's just a shade-tree, amateur mechanic myth. If catch cans solved the problem they'd be on all GDI engines, with a simple drain back to the oil reservoir. For the blind, catch can faithful, I'd ask a simple question. Why are so many manufacturers spending millions on combo port and DI engine designs if the problem could be solved with a simple catch can?
I'm relatively certain that's pure BS, and if it were true, you have either massively screwed up the installation, or have an even bigger problem. So tell us, exactly how much oil do you add every 1000 miles?
At least some of the catch can fans here have been honest enough to show how little oil actually shows up in theirs and actually admitting they're not adding any oil between 7500 mile oil changes. I'm adding no oil between changes either with no catch can.

Total BULLSHIT and a pathetic response. And since when has "ignorance" become name calling? LOL.

Hmmm... 100,000 C7’s sold.
Yet...not even *1* documented case of this level of coking happening on a C7?
I would think 100,000 is a big enough sample size to see it.

I could ask you the same question. There is no hard data to back up your contention that catch cans solve the problem . . . none whatsoever. I've been waiting for the faithful to produce it every time this subject comes up.
It never ceases to amaze me that amateurs seem to think they are somehow smarter than world-class engine designers when it comes to these things. If it worked, there'd be a cheap-***, catch can with a drain-back to the oil pan on every GDI, and they wouldn't be investing a fortune in the development and evaluation of combo port/GDI systems. The catch can solution would cost them pennies if it was a solution.
