Cleaning carbon from piston crowns and combustion chambers

#1 PostAuthor: PAULJAC47 » Tue Nov 25, 2008 6:22 pm

Hi All just took the head off my Z1B to renew valve guides and seals does anyone know a better way of cleaning carbon from pistons crowns and combustions chambers other than by just scraping with a soft wooden or plastic tool?

A bit of elbow grease & soft scraper is best... :|

You could try a 'soft' wire wheel...... :?:

Oven cleaner works perfect.

Caustic Alkaline Oven Cleaner and Ali!!!! You're living dangerously there.
That stuff will mess with your Ali's surface layer -could be storing up big trouble for the future.

I would talk to the Debben twins.

They demonstrate time and again that when it comes to engines they know what is what :!:

You don't need a Alkaline Oven cleaner.Ask your wife for her oven cleaner foam.I'm working with it since years, and had never problems.

Red x and soft rotary brass wire brush worked well ,a smear of vaseline around edge of piston stopped any crap going down bores it holds onto carbon when you turn engine over and piston goes down easily wiped out then with clean rag.......

Another way that I have seen working, with my son doing pistons etc in a Toyota V6 engine, is using carb cleaner which comes in aerosols (he got his from Halfords where I have a trade card). Let it soak into the carbon and it comes off relatively easily with gentle rubbing with a cloth.
