Cleaning carbon varnish.

[KiwiBacon]

Has anyone got a hot tip for cleaning up coked and baked oil? The stuff that has been burnt to a carbon varnish.

Specifically turbos and cylinder heads so the materials are steel and aluminium.

Hot dip

You could also try CRC carb cleaner, its pretty corrosive.

Oven and blast.

if you have disassembled the heads, just use a wire wheel on a bench grinder to buff it off.

If the motor is apart, take the pieces to a local engine rebuilder and he'll know how to clean whatever you bring in. Hot tanking steel heads always left them really clean for me.

I'm cleaning a motor which is together and turbo pieces which are apart.
What I'd really like to know is what do engine rebuilders use in their cleaning tanks.

I can't use a wire wheel due to too many tight corners, hand work will take a long time unless I can find an appropriate cleaner.

There is a mobile company that supplies the chemicals they use, they also sell and service sand plasting chambers etc.
I think its called Enviro Wash.
I think.

i've only even known people to use paraffin to clean engines, at college we have a cleaning tank with a stiff brush which the paraffin's pumped through.

parraffin sounds good does it work that good? we got this stuff called ozzy juice same system as the parrafin i dont think it works good enough on carbon though its a enzyme but startoff with a parts washer its a big dish washer and look into a chemical dip thats aluminum safe the ones for cast iron are awesome but your aluminum will disappear if not i can amagine theres a fiber type scuffer or wheel out there that wont tear up aluminum but make sure because some can take out steel

Give them a ring, see if they have anything.

The guy that used to service east auck was very friendly, if its the same guy he will either have something, or know who does.

I know the stuff well, just never considered cleaning engines with it.

It's available from most protector safety shops (for some random reason).
