Upper Engine Cleaner in AU

[JMO]

There is a thread in the B Series section about using Upper engine cleaner in their engines to clean out some of the gunk. Has anyone tried this (or Seafoam, a similar product) on an AU or would the higher k's of the engine be an issue.

Here's the thread:

I have been "washing" the interiors of my motors for 40 years with water injection with good success , if you run big boost it's a must imho
years ago it was common to actually run a little water through a carboned motor ( into the induction)on a fast idle and blow all the carbon out but with modern fuels I cant see any reason to use the cylinder stuff after all a tank of hi-test and the motor will be clean

Is "high-test" a fuel additive or something else? So it's not worth doing?

IMO the best and cheapest option here is to use a can of "Subaru" upper cylinder cleaner, When i was working for Audi this is what we used to use on a lot of these vehicles that used to carbon up the top end that badly that they would not even start...
(A lot of the euro. cars suffered this prob. due to multi/small valves and lower quality local fuel)
An onboard carbon blast/clean would do a more thorough job but for the cost i would be popping down to the local scooby do dealer and buying a can of this.

So the engine being older and most probably having a larger amount of buildup isn't an issue? No chance of chunks coming off and doing damage inside?

Sorry if I'm asking a lot of questions, I just don't want to break anything, especially anything internal :P

I don't think it's that good for worn motors, expect leaks from breaking down seals etc. I'm not game to try.

If it aint broke.......

I used the Subaru stuff in 400,000km old VP V6 in my old corona and it didn't leak after. Idle smoothed out and left a lot of black crap on the driveway.

From my understanding of the way motors operate, this stuff would have to do more harm then good. The cleaner supposidly frees up built up carbon (which is course). When the carbon frees up it needs to be forced out of the top end, which would have the same effect on piston/rings/barrel as throwing fine sand into your throttle body. It may be usual as a preventative to carbon build up on newer motors, but cant be good for older ones.

No one should be worried about this stuff damaging your engine. If you pulled a head off and sprayed it directly onto the carbon you would see that it melts the carbon away and doesn't break off into giant lumps that will destroy your engine.
