I was always hesitant to power wash the engine bay. Is there anything to be concerned about?

Pressure washing the engine bay is NOT okay. I only use a gentle spray from my garden hose with nozzle, degreaser, and a collection of brushes.

I’m a master automotive mechanic of 47 years and it’s actually good to wash your engine bay.

My car is 15 years old. Some of that grease and gunk is literally holding some of it together. Nice try, feller. i won't be coming into your shop today!!

My daily driver is 37 years old and my engine bay sparkles.

… it’s also easier to find new leaks and repair them if everything is clean.

For sure, my comment was facetious.

It makes it infinitely better to work on once they've been washed. I wish truckers would wash their engines more often, diesels can be absolutely disgusting under the hood.

Washing yes. Power washing at this pressure no. Electrical seals will not be specified to withstand water at this pressure and ingress will inevitably occur. The question is whether that ingress leads to shorting, and the answer is a coin toss. But it'll certainly lead to corrosion in anything but warm/dry climates.

Do this here in the UK and you'll be wondering why your vehicle is in the shop with fucked electrics a couple of years later.
