If anyone doubts that we need at least one oil catch can then this will give you a fair view on GDI engines and where the gunk goes...

Also starring the hyundai GDI engine....

I don't have 20 mins to watch a video and I don't know what this relates to...
Maybe a short post would be better ?

Maybe... modern life, who'd have one...

At the risk of repeating all the info from the rest of the thread... and placing "plenty of info about the issue on Google" on here.

Direct injection engines fire fuel direct into the cylinder NOT INTO THE INLET MANIFOLD, so any oil that gets evaporated along with blow by fuel and travels from the crankcase through the emmisions pipework back to the air intake. Any of this vapour that does not get burnt at ignition ends up in the air intake system as an oily crud in the inlet manifold and on the back of the inlet valves, valve seats and valve stems.

Additives in fuel will not clean this crud but will help the expensive injectors.

A well fitted sealed catch can with baffles will help remove 95% of the crud that gets sent to the air intake. The pipework works under vacuum conditions and will upset the engine, if the catch can does not keep this vacuum in place.

Getting a garage to blast some ground nut shell's through the intake area with the valves shut every 30k miles also helps clear the crud.

You can also spray a cleaning additive into the air intake after the MAF sensor... to soften and remove the carbon build up... And driving like you stole it... Or was that another video...

The hyundai GDI engine features at 4 mins 40 secs but Direct injection features in first 2 mins before the alternatives...

Migration to DI on new cars was the primary reason I paused buying new ICE cars and just kept driving my older port injection ones(thankfully with a lot of life left in those) and moved on to EV. If I Would own the car with DI engine, I would put oil catch without much of hesitation, as I keep my cars for very long time. Not doing it - would be very pricey, because of it would happen right after warranty expires. I am not compelled to buy any used car with DI engine, because of it would have contaminated intake already. Really sad situation.
