I recall as a teenager hosing down the engine on my 72 Buick Skylark and when I tried to start it.....nothing. I forgot to cover the distributor cap. So I've been a little gun shy on cleaning the engine bay on my 530. Not that it really needs it but it is getting sort of dusty and I want to keep it looking clean. Are there any precautions I need to take when (lightly) hosing my engine bay down? Hints? Tips? Suggestions? As always thanks in advance!
