There is NO good point for shooting that stuff into the engine....
It's not a good thing to drive that muck into the motor...
Subaru Upper Engine Clean is similar to what we use on 2 stroke Marine...
If you want the muck out of your 3.0 - pull the intake off.... short cuts will cost engine wear.
So if I was going to do it I'd remove the plastic 90 degree bend before the throttle body, spray it into there to clean the EGR intake and front left and right runners which seems to be where the crap accumulates. Leave it for 5 minutes while reassembling. Start run, stop. I'd then remove the map sensor (top of throttle body / intake divider and spray in more there towards left and right sides of the intake. Etc. There are also some obvious vacuum lines you could unplug to inject it whilst running however you'll like flag an error as they're all there for a reason so disconnecting one to spray stuff into the engine might make it sad with ypu
Bit of a noob question - is there a 'how to' anywhere on accessing these parts in order to clean? I have a workshop manual, but it's not particularly well laid out, with an index etc...Quote:

Meccles, which crew did you go to for the tune?
Simmo
I used Roo systems their head office in Banjo. Really couldn't complain about them other than price. They did exhaust ( which my local mechanic reckons is excellent) tune and fitted LLAMs for me.
Meccles,
Thanks for that. I contacted ROO Systems with a query about EGR delete. They rang back and did the hard sell about including a tune and did say that the tune is detectable by the diagnostics software when being serviced. He also very strongly recommended an oil catch can. Have you, or anyone else fitted an oil catch can? From what I understand all the goop that forms the clogging up is essentially from the oil mist from the PCV. Mixes with the EGR gas with a not very good result.
I have a 2014 RRS TDV6 which is still under warranty so a bit nervous about doing this untill out of warranty.
Cheers, Simmo
I waited until I was out of warranty before I did anything. They are correct any work done can be picked up. Re catch can, got a quote - it's a difficult job due to space etc- and decided against it.
