Powerwashing motor?

[DIESEL KEVIN]

ive been wheeling alot lately, and my motor is just getting FILTHY and i feel kind of bad for it lol , i got introuble at school with my truck,(roasting the tires in the parking lot haha) so i cant drive it for a little bit, so ill just take the time to clean the motor up, ive talked to some people and they say that you can directly powerwash the whole engine with out shorting anything out, is that true? does anyone use that engine bright stuff? what should i prevent water getting into? thanks

I have done it with no problems. What I do is I park the truck where I am going to do it at the night before. Then the next day I go out there, spray the engine with Seal Gunk engine brite foaming cleaner. Then I spray it down with the pressure washer. I been doing this ever since I got the truck. I have never had a problem yet.

The key thing is to do this with the engine cold. That is why I park it where I am going to clean it the night before. That way I don't have to wait for the engine cool down. This takes away the risk of cracking a cylinder head or causing damage from cold water hitting a hot engine block.

Also I do not cover the alternator up or none of the other electrical. I do however put a plastic trash bag over the air filter.

Some say you can wash a hot engine if you leave it running. I learned from experince while in the Marines this is not true. Cast Iron cylinder heads do not like cold water being sprayed on them when they are hot. They will crack I garuntee it.

So if you do it do it with the engine cold. Do not even start it up to move it. That is why I advise you to park it where your going to wash it the night before.

I do it all the time with a pressure cleaner, and have no issues. Leaves the motor nice and sparkly

Your dirtbike wasn't a honda was it. I used to wash my honda quads right away when they were hot. I never had a problem with them.

We washed almost everyone we worked on at the dealer. I washed mine at every oil change just to keep the dust off it.
