flyboyike That "catch can" sounds like a fairly dubious solution. For one thing, the EGR system is part of the emissions control system, and any modifications thereto may be illegal and/or jeopardize the warranty. Secondly, it sounds to me like it would only "catch" oil vapors/drops, but do nothing about un-burned fuel and other byproducts. Almost sounds like Sea-Foam every 1K is a better idea.

lookin4trouble The carbon build-up that is caused by DI on your intake valves is hard as a rock. It literally has to be scraped and picked off. You'd have to Seafoam every 1K miles from date of purchase to see any results. It's just a known problem that doesn't have a solution currently.

Juicedz What about sea foam?

lookin4trouble Meh. Catch cans and "full synthetic" oil are just a band-aid for the problems of a DI engine. Doesn't matter which catch can you use or how fantastic your oil, your engine is gonna get gunked-up sooner or later. DI is great for combustion efficiency, but port-injection is much better for engine longevity. Valve cleaning should be manufacturer warranty maintenance on all DI engines every 60K miles.

ChrisRyan I saw solid shifter bushings for $25 in the recommended row at the bottom of the page. My brothers Ralliart was 10x better shifting after installation of
solid bushings.
