81 240D. 386000 miles. I'd like to power wash my engine. I'd really like to get it as clean as possible. I'm concerned about the location where the dipstick enters the bottom of the engine block. I guess it ends up down in the oil pan? The tube holding the dipstick is loose and and I can wiggle it around quite a bit at the top end which indicates that if there ever was a seal at the bottom where it enters the engine it must have long since wore out. Which concerns me regarding power washing the engine. If there is no seal there any more presumably water can get in. Is this a realistic concern or am I just being paranoid?

- Peter.
