Hi There

This is driving me crazy, I know it's suppose to be such a simple task but I have looked at other posts and cannot find where to add the Upper Engine Cleaner to my MY07 (SG9) Forester 2.5 X Luxury.

I have found one place with a hose and when the engine is running if I remove the hose the idle almost dies, and when I reconnect it picks up again so I think this is an intake valve.
If I am wrong and I add the UEC can it seriously stuff up my engine?

I have posted 3 photos
The first is the whole motor (front on)
The second is from the passenger side (the car is RHD)
The third is a close up of the pipe (coloured red) that is attached to a nipple.
Do you think this is where I should spray the UEC?

OR does anyone have another suggestions of where it should be applied?

This is supposed to be so easy????????


Cheers for any help

Dagil

Unless you've put an extreme amount of mileage or haven't taken good care of your car up to this point, I'm curious why you would need to use this product on such a new engine. Carbon buildup inside the intake tract shouldn't be an issue on a car that's as new as yours is.

Dagil,

Here's a link to a pdf from endwrench listing the procedure.

here's the text

2. On 2.2 and 2.5L engines only, remove the bolt

the air cleaner case “B” and the air cleaner element
and set them aside. (On all 3.OL H6,
remove the entire air intake chamber).
3. Start the engine and maintain 1000-1500 rpm.
4. Spray engine cleaner GM Top Engine Cleaner

upper air-stream of the throttle chamber for
approximately 10 seconds.
5. Stop the engine and let it sit for three minutes.
6. Restart the engine and maintain 1000-1500
rpm.
7. Spray engine cleaner on the upper air-stream

UPPER ENGINE CLEANER is a recommended Subaru product used to remove gum, varnish and carbon build up in the combustion chamber.
It is recommended every 12000 klms by Subaru

As I do a lot of short journeys (stop start) the idle become a little rough
so this can help.
This product also gets a lot of good press and user comments.

Unlike Seafoam it comes in a spray can.
You spray (if you can find the damn inlet!!!!) half the can into a warm engine wait 10 mins, runs the car then with the engine running spray the rest of the can in the same inlet.

When the can is empty cut the engine, with 10 mins the take her for a burn and she should be running heaps smoother (well Idling smoother)

Thanks for that.
I have read that before but unfortunately that's different to the way the Subaru UEC recommends to do it on the can.

They say I need to spray down a convenient vacuum hose from the intake manifold.
I have detailed the rest of the procedure in the previous post.

I just need to determine where a 'convenient vacuum hose from the intake manifold' is actually located!!

I didn't think it could be so difficult to find???

Cheers

Sounds like you might need to pay someone a visit so they can point to a suitable hose for you to spray the UEC into. I'd suggest either drop by a dealer and ask them or your mechanic.

Is it recommended or 'approved'? Not the same thing!

At a guess its 'recommended to improve dealer margins at service' what a waste of meoney and a rip off, no modern engine on modern fuels should need any such help!

Well 'recommended or approved' I just bit the bullet and sprayed it into my engine through the hole I had mentioned and as described on the can.
All I can say is "I AM IMPRESSED" !!!!!

This is no placebo effect, the idle runs very smooth, the engine feel 'perky' and more responsive.
As I do a lot of stop-start driving, sitting in city traffic, I don't often get much time to really 'open her up' so to me this is a good alternative.
My car has just hit 37500 klms

By the way there has been a lot of good things said about this product, if you can get it try it for yourself, it's not expensive but I think you will be pleasantly surprised.
