Cleaning the Sump
« on: 17.03. 2009 13:12 »
After draining oil and removing the sump plate, what might be a good way to flush out the bottom of the crankcase where some  carbon and, potentially, other particles or bits may have accumulated? I have considered  injecting a cup of petrol (with the sump plate on) and gently (so as not to wash down the cylinders) turning over the engine several times to agitate, then, of course, removing the sump plate again. Other ideas?

Diesel would be better but pour alot more than a cup.

Thanks.

Do I need to worry about washing down the cylinder walls or washing out the big ends? And, is it even necessary or commonly done?

I wouldn't bother. The internal crankcases are being constantly washed with hot oil as the engine runs, any crud in there will settle in the sludge trap or filters.
