Wanting to give my motor a good cleaning. Would it be a problem to
power wash it? I of course would not use full force. Would like to do a little painting in the engine compartment afterwards.

Thank you.
 
I always warm the engine a little before I powerwash an engine, Not hot! Just warm, it dries a lot quicker and if I get water in any electric stuff it dries it.

I have an Epps wet-steam washer @ 3000psi. did my engine quite nicely.
One thing is discovered though was all the crud that gets blasted off ends up all over the inside of the fenders.. now I put a tarp of them before cleaning.
 
Actually, I just use Gumout engine clean, the foamy stuff, let it soak and hose it off. This works for annual cleaning but caked grunge go for the pressure sprayer. Follow the cautions already posted and wear goggles too.

Doesn't Oven-Off take the paint too ?

In all honesty, I've used it on engines that stripped them to bare metal and others that didn't even change color shade! Industrial grade engine paint doesn't seem to be affected. Same for sheet metal painted parts, works on some, not on others.

I use gasoline and a paint brush to clean the engine. After it's clean and dry I put a few drops of oil on each head nut and any other unpainted parts. After running the engine and getting it heated up the oil spreads to a thin coat of oil all over the engine.

I used VHT Newcast to paint the exhaust manifold, and for 3 years it looked like a new manifold, but it's ready for another blasting and paint job as you can see. This is just a temporary engine, so I don't really bother keeping it very clean.

The camera angle makes the fan belt alignment look way off, but it's perfectly straight. :)
 
Word of caution:

Look closely at your fender and sheetmetal paint in area where you powerwash. If there are any cracks or bare spots in the paint, be careful as the washer can lift the paint right off in large chunks!

You're missing your engine pans. According to some here, that must attribute to overheating :eek::cool:

Yep, I have them in the basement and will put them back on when I reinstall the original engine. The car cools great since I did the vinegar treatment. Someone painted the cast water inlet black, instead of the correct engine green.
 
Tom, That's a good lookin' dependable WORKHORSE engine room, don't apologize for nuttin'! Glad to see you don't use that danged armored cable clamp. Can you imagine how many head gasket leaks or maybe serious engine damage were caused by those clamps?? Have a Merry Christmas, Tom! Bill W.
