I need to pressure wash my td5 engine to investigate an oil leak, is there anything that I should avoid apart from the obvious? I'll happily wash my 200 engine, I'm just a bit dubious of the electrickery in this engine lol!
just have the engine running do mine regularly
if you need to get oil off either spray it over with some gunk or similar first (unless you have a steam cleaner then should have a detergent with it)
