Hi guys,

I always see people show before/after of engines they detailed. Most of these cars are new or relatively new. This means that they have a bunch of plastic covers that already protect all the elements like the air intake system, alternator, sensors, etc....so it's something that your mother could probably clean safely.

My question is.... how do you detail engines that are not that new? Engines from the 90's and early 2000's that don't have a big plastic panel that covers everything...?

What should I cover up with plastic bags or foil?

I've always wanted to detail my engines but I am worried about getting water in the spark plug valley or other areas that I shouldn't get water in.

How should this be approached?

I hope this thread help alot of people because I am sure I am not the only one who is wondering about this issue.
 
I don't cover anything, but I tent to stay away from the open electrical things. If your going to cover anything I tend to cover the alternator and distributor cap if it applies. I just take an air hose and blow all the water out of the valleys and whatnot.
I'll plastic baggy the intake if it's an open box or has a cold air intake.
 
I dont cover anything as well except for my open air intake....I just use a mist to rinse it and not a strong stream..also as soon as I am done I pull out my blower and blow all the water I can out of the motor..The I start it and let it run to operating temp to steam off the rest of the water.
 
i have to say the only thing ive ever covered would be the air intake and use a low pressure when spraying down the engine and have never had any problems
 
I start the vehicle first before I start spraying. As long as you don't hose it down full blast you'll be fine. After I rinse it I take an airhose to it, then applying the dressing.
