Is it possible??

Without removing the head to clean out the cylenders , piston tops and head, is there any way that I can 'carbon clean' my car (carb XE 250ci).

Otherwise, how much (rough) should I expenct to pay to have it done for me??

Suburu dealers use an aerosol carbon cleaner on their engines at each service
Its available through their spare parts.
They use 1/2 the can down the spark plug holes, let it sit for 1/2 hour or so, the start the engine and spray the other 1/2 can in via the air intake.

Not sure what it costs but it doesn't seem to do them any harm

I'm not too sure about this, but I have been told that removing the carbon is bad.

On older cars the carbon may be helping to seal the piston in the cylinder, thus preveting blowby wich results in loss of power etc.. Cleaning the carbon on new cars however may be different, as the pistons already seal well in the cylinders.

Doesn't Redex help clean carbon deposits?

How about a long-term water injection set up. Steam cleaning at it's finest, and a few more neddies, too! :s3 :s6:

I did basically the same to my mates 1 Litre, 3 Cylinder Daihatsu Charade with a can of Carby Cleaner.. and it made a hell of a difference in his car!!

Then i used the rest in my car (just into the carby, not the spark plugs) but all it did was clean up the carby (VERY nicely i might add!).. but no performance/sound difference. This is probably due to the fact that this motors only done about 15,000 K's so far :s5

Be buggered if I'd use any of those sorts of products on any of my cars, where does the carbon go?? Down the sides of the pistons etc, mate used something similar a while back on a Toyota Celica and two months later it was stuffed, lots of blowby, oil usage etc, on pull down the bores where marked to hell and the pistons weren't much better.

I'd assume the majority of the carbon along with the product you spray into the engine would flow through to the exhaust system with the rest of the gasses.

And thats no joke, a cheap trick is to remove air cleaner, start engine and hold it at about 1500rpm and spray a litre or so of water into the carb.

This worked well for my old Mustang V8 when I first got it, it used to ping, did the trick and no more pinging.
