i have a 95 z28. i live on a gravel road and my engine bay is filthy. would spraying some engine degreaser and spraying it with a power washer hurt the optispark at all? and if it would, what is another method of cleaning the engine? thanks

 

last thing u want to do is pressure spay your opti. u can cover it and any other electronics like the ecu, alternator and ignition modual with plastic. u may want to consider using a garden hose, not the sprayer, in the engine bay.
