I know with our optispark we should be extra careful, so what are you guys techniques to clean your LT1 engine bays? I know we should steer clear of the PCM, Opti, and alternator. How many of you use the pressure washer? Or just a rag and elbow grease? I have a car show Saturday and want my engine bay to be spotless

 

Wrong Forum: See "Show and Shine".

 

Well...when he does wash his engine bay...he'll be back to Engine Tech with a "No start" thread, LOL

 

If he uses a pressure washer, there is a good chance of that.

 

well what i do is get a bucket of hot water and a few rags, dip and wipe down and after a couple of hours of cleaning and drying youll be happy

 

i use simple green and rags. I heard stories ouf guys hosing down the whole motor tho. If your opti is sealed is the big issue here.

 

Pretty much the method I use as well.

 

I have power washed my engine with no problems in the past and then with one opti replacement, I do it again and codes everywhere.

The damn optis are too sensitive. I would not get water near them.
