yes, you can use a pressure washer, you just have to be very careful with it.

I thought that the optispark pack was sensitive to water, so I kinda refrained from using high pressure water to clean my engine bay. I did use some royal purple degreaser which is biodegradable and some no touch and looks good. anyone used a home water hose? would that be ok for the optispark?

Ive used the house water hose, Im just carefull. Now a days I used a spray from Autozone that cleans it all!

No no. Very very bad idea. If your not a mechanic, or someone that knows what they are washing, and where they are sending a powerful stream of water to... all it takes it getting one sensor wet, and you'll have your hands full of very expensive problems.

that's if you don't know what you are doing, yes. Its never a good idea to do something if you don't know what you are doing.

most underhood sensors are moisture sealed anyway (you think it stays dry under there driving in the rain?)

I use to detail cars, and cleaning the engine bay is very simple. First cover places that will get water like the alternator. Then rinse it off with a power washer, but be careful where you spray. Then using your degreaser spray everywhere, use a tooth brush and some small scrubs go over areas with dirt.
Once that is done get the power washer and spray it all off. If you have access it an air compressor, spray off most of the water then dry it with a rag.

Now to detail the engine bay, tire shine works wonders on the plastic and just about anywhere under the hood.

Never thought about that, but it makes perfect sence.

just if it hits the belt you have to replace it, it will squeal like mad, and silicone eats rubber
