I see several options:

Any advice?

First, use the cleaner to wash the engine, if it will stay running.
Let it get up to operating temperature, then shut it down and dry
entire engine with rags. Wait a few days and carefully look for leak.

Probably from the crankshaft bearing seal where the pump is connected
and it's not visible. Unlikely to be a head gasket.


Why do you use old oil? If it's too dirty for your car, it's
certainly no good for your B/S engine.

Where do you get the idea he used old oil? He said he used 10w40
synthetic leftover from a car oil change i.e. used 4.5 qts in car, had
..5qt leftover for the pressure washer engine.

As for the oil itself, I use M1 5w30 synthetic in all my gas engines
from the truck to the lawn mower and have no issues.
