Can you get water in the Oil Pan from Power washing?
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.

I think you're being rightfully concerned. Wrap the potential leak with tape, also tape or bag the brake master cylinder reservoir. Wash away.

I believe there is a replaceable O-ring on the dipstick where it enters the block.

You can also
power wash into the battery. Modern day batteries that are not labeled "sealed do not open" actually have vented caps. I killed a 4 month old one and happened to be at AutoZoo when the batt vendor was there. BTW, if you feel inclined to carefully pry off those vented caps ONLY top it off with steam distilled water.

be careful with the injector pump, extreem temperature changes with a
steam, hot water washer, or even cold water on a warm engine can do damage to the pump. these have close tolerances inside. I have read it here on a thread, think it was junkyard jim talking about it. also read it in some publications on diesels. be careful, and wash away. charlie

You shouldn't power wash engines. You should spray it with degreaser and wipe it clean with a rag, perhaps use a plant sprayer to wet it down.

I've always used a degreaser and a low-pressure hose down on a cold engine to be on the safe side. It always seems to remove all the gunk and never had a problem on my iron engines and I've probably done it a dozen times or more.

With regards to powerwashing, bag / tape all areas that could be a problem. Avoid direct spray on things like rubber seals, fuse box, battery, etc.
Don't be fooled by high PSI numbers. Your not looking for pressure, GPM is what does the cleaning.

My garden hose will flow 5 gpm and won't clean squat off an engine. A 1300psi pressure washer will use a quarter of that and clean things right up.
I especially like a steam cleaner for really dirty engines and never have had a problem cleaning under the hood or under the car. But I think the OP is using a pressure washer, not a steam cleaner/washer. |

I can't wait to get China running, and go spray off this nasty engine that came from Scar. YUK! The engine degreaser at the car wash works great for me. Just spray and let it sit, then rinse, using both the high and low pressure. High pressure on the front, neat the vac pump, balancer, etc. And high near the oil filter housing. Always low pressure near the IP, lines, hoses. High pressure on radiator and condenser. Reminds me, I need to pressure wash that radiator before it goes back in. Now where are those scrubbing bubbles.......
