Engine carbon cleaning

Recommended Posts

I know this will get very mixed opinions but has anyone done it to their Supra ?

we have a new machine at work and I can get it done for free apart from cost of oil and filter

but I know there are very mixed reviews on this, even most mechanics I know are very wary about doing it on there own cars lol

I just thought mine doesn’t do hardly any miles at all and may benefit from it .. though I’m also a true believer if it’s not broke don’t try and fix it lol

You've just answered it for yourself mate.

Only engines which are direct injection (not over the valves) get much benefit from this i thought?

The Audi 4.2 FSI engines had massive issues with carbon build up as the fuel didn't "wash" over the valves.

I wouldn't have thought the 2JZ had these issues?
