We all know our direct injection motors eventually accumulate carbon build-up on our valves and heads. Oil catch cans can help reduce this, but I never bothered. I've since come around (after 65K miles), and finally ordered an oil catch can. But what to do about the already accumulated gunk? Conventional induction system cleaning is ineffective, and can be very harmful to our turbos. It's definitely NOT recommended. A quick Google search for my area returns a BMW dealership. Apparently BMWs have the same issue that we have, but worse. Their solution is to partially disassemble the top of the motor to get access to the heads and valves, etc, and blast the gunk away with crushed walnut shells. It's much less damaging than blasting with glass beads. My question(s), after a long-winded intro, is; who on here, particularly in the midwest, has had this service done? Where did you have it done. What did it cost. How many days were you without your car? Was there a noticeable improvement afterward? Surprisingly, my local Ford dealership does offer a direct injection cleaning service, despite its lack of effectiveness, and its potential for causing damage. Anyone please chime in if you have any advice, and especially if you've had any experiance on this subject.
