Ah, got it--thanks...although in my case I think I need to pull the hose going from the OCC to the intake manifold since the hose that's currently connected to my PCV valve no longer connecs directly to the intake manifold...
May not be a problem, but I'd put a vacuum cap or tape over the open exit tube of the occ to be sure.
The friend who'll help me with the CRC called them for another reason.
In the conversation he mentioned my planned CRC treatment - and saying "easy driver" - the guy offered that he'd seen as much or more carbon build-up from Easy drivers than aggressive.
Can THAT really BE & Why?
He also said he preferred CRC Injection - "at the Air Filter" (Intake?) for better spray "atomization" thru the Throttle body & Turbo. Only downside is IF the hose path has a DIP that promotes puddling of the spray.
No idea what that means but it's helpful to get your critiques of theories of guys in the business.
P.S. Re OCC in Winter, what's the OCC "plan" if traveling in a freeze area and your car is in a motel lot (outside vs home garage)?
Yes, as the car doesn't have a MAF sensor you can spray into the intake tube at air filter, but the spray needs to through the air intake, turbo, down to the intercooler then up into the intake manifold then to the valves. Whether the distance and/or the intercooler position would create any problems, I really don't know.
Same as easy vs hard driving, I have no knowledge that one would cause more of a buildup on the intake valves more than the other, especially in this dgi engine.
As far as freezing, only heard of a couple instances when the car was exposed to very low temps, and in one instance, the occ was placed quite a distance from the engine which added to the problem. If, in fact it did freeze, similar to the one way valves installed if they become inoperable, certainly don't know how one would know unless seeing oil residue at unusual locations. It would be similar to the PCV valve being stuck closed, a lot of pressure builds up inside the engine looking for a place to get out. I would consider this a very remote possibility.
