Is it safe to degrease and hose down/pressure wash the engine bay of a 1994 80 series? I’ve washed all my Toyota and Lexus cars many times with a pressure washer (safe distance) and never had any issues (LX470, LS430, GS430, ES300, various years Avalon and Sienna). Never really covered anything in particular, just sprayed it all down with a cleaner and washed everything.
The reason I ask is my brother has a 2JZ SC300 and back when I was on Club Lexus (forums), you would always see threads popping up of someone’s 2JZ running like sh** after being washed and the culprit was usually water in the spark plug galleys. They recommend to not hose down those engine the traditional way. Seeing how the 80 series engine layout is similar to a 2JZ, I thought I’d ask before I do something stupid.
