Any of you guys using an oil catch can? I've been researching them to figure out if our engines would benefit from one. Seems these things are especially necessary for DIG, turbo, or supercharged engines. The fumes from the crankcase that are rerouted back to the air intake contain more gunk when there's thinner oil used, like our manufacturer's suggested 0W-20 synthetic oil. The gunk vapors coat the intake manifolds and coat the intake valves in carbon buildup. On DIG engines, there's no fuel sprayed on the intake valves that'll dissolve the carbon buildup, which degrades the engine's performance faster.
Some of the videos stated that modern DIG engines have learned from the mistakes of early generation DIG designs and placed another fuel injector inside the port to periodically inject fuel on the intake port to clean the valves, but I doubt our engines have this feature. Videos also stated that latest designs may already feature a type of oil catch can, but, again, I don't think our engines have this.
Any of you guys know anything about this or is it just another snake oil product?
