Since my track day, I know my rat's nest vaccuum lines have ingested some oil, which could be contributing to some slowly working solenoids.

Is there any easy way that I could hookup some brake cleaner to ONE or TWO lines while the engine is running/idling to "ingest" some brake cleaner/degreaser into the rat's nest vaccuum lines ?

If so, what are those lines ?

I thought about the PCV valve, but that would go into the intake as well. Perhaps one of the pressure tank lines, and the vaccuum tank line ?

I'm sure I'd also have to rev the engine to past 5000 RPM to open-up the plumbing that is activated past 4500 RPM.

I really don't want to pull ALL rat's nest lines!

Thanks,

BTW: is this a SAFE thing to do, or would I cause something worse to happen ?

 

Brake cleaner, degreaser, carb cleaner, etc is really harsh stuff. I wouldn't be surprised if it attacked the plastic of the solenoids.

IMO, it's best to remove and blow out all the gunk in the lines controlling the turbo solenoids. So if it's a line attached to the turbo control solenoid (vaccuum and pressure), charge control, charge relief, wastegate, or precontrol, clean it out. Otherwise leave it alone.

That's what I thought. What about those "electronic cleaners" that are plastic safe, but still degrease ?

I have no idea - but I don't see any reason they wouldn't work.
