I am thinking of a Christmas present for myself and would like to do a motor wash out and buy myself a pressure washer. Is this something that is safe for our motors? I know there are plenty of youtubes saying do it but not to sure. I would also like to wash the back of the brembo's that I can never get clean.

 

Take the wheels off to wash the brakes

for under the hood, spray it down with a mist spray (not high pressure), scrub it down with brushes and soap and such, and rinse off with a hose (not high pressure)

Pressure washer is not friendly to electronics even if they say they're waterproof

 

 

The engine bay can withstand being wet and hosed down. All connectors that matter are weatherproof. When using a pressure washer you will most likely be using a 25 degree tip anyways so it would be perfectly fine. Just be mindful of connectors.
