Thread: V8 Carbon Clean Recommendations

I want to give V8 combustion chamber, valves, etc a clean preferably without removing anything or is it best to bite the bullet and attack the rubbish manually.

Having seen a combustion chamber spotlessly clean with a blown headgasket (water entering bore) I tried water injection to reduce pinging in my hi comp P76 engine. Had a head off last week and it looked great, only 1mm of crusty stuff and no black carbon.

1) Change oil very regularly (5000km)
2) Use a detergent oil (good turbo diesel oil has deteregents)
3) put 100ml of good non-synthetic two stroke oil in a full tank of petrol

Put a tube connected to the vacuum hose on the side of the plenum chamber vacuum, other end to a litre plastic container of water, you also want to restrict the flow some how so it doesn't all get sucked in in one gulp.the idea is then to go for a good drive at high speed and let the vacuum suck that water in. It will steam clean the bores etc, just like a blown head gasket does. Do so at own risk. It cleaned mine out very well when I did it

Dont use it near plants or breath in the gasses from your exhaust but it works really well

Fit forced induction. nothing like fitting turbo's then watching the carbon deposits shoot out on the dyno

You have touched on a very interesting point there on no. 3 there is an argument for putting two stroke in diesels to help lubrication but not heard of it in petrol engines, do you care to elaborate?
