Is it safe to use the engine spray mode at the car wash on LT1's or will I short out the opti?

If not, how do you guys clean your engine?

 

I've washed my engine at the self serve car wash before and have had no issues with the Opti (mine is vented and has 108k miles on the original).
If you do decide to wash the engine, just be sure not to spray directly on the Opti or water pump area.

Good luck!

 

I've washed mine with Gunk Engine Cleaner, and sprayed it down with a hose a few times....I was nervous the first time, but I've had no problems.

 

I always cover the alternator w/ a bag and put a bag inbetween the water pump and opti. Then I just go back and detail the alternator with a rag. I guess I'm just a bit too careful

 

As long as you stand back a little when you spray and not spray with force directly on anything (especially the opti) you should be ok. I've had mine to the car wash once since I've had it (been a week) and my mechanic (who is also a friend of mine) just said don't spray up close and don't hit the ignition directly and you should be ok.

 

ive cleaned my engine bay maybe 10 times since i got the car, never a problem just be carful
