Default Planning to get the undercarriage/engine washed...what to cover/protect?

Going to get her up on a lift and do the full underside...possibly the engine from the top too.

Looking for the key things (mostly electrical) to cover. Will probably need to use a light pressure wash to get the funk off.

I've been researching but haven't found a definitive list.
  • Rear fuse panel
  • Distributor
  • Transmission breather
  • Spark plugs (not sure you you can add protection)
  • Air cleaner
  • Oil breather

What about
  • Heater blowers
  • Any front area electrical connectors?
  • WUR,AAR,Intercooler temp connectors
  • any other breather tubes

I'd prefer to be overly cautious. Will tell them to use pressure minimally, at angle, not spraying seals directly.

What are your thoughts on a blower or compressed air to aid in the drying process. Compressed air might push water into areas not intended?

Thanks for any input/advice.

I wouldn't spray the motor down. You are better off cleaning it off with solvent and rags. Too many electrical components to get wet.

There isn't much in the way of electrical stuff to worry about on the bottom of the engine and top/bottom are separated by the engine tin.

Ryan, go to the concours forum and either search or ask, lots of good info there for keeping your car clean. Hope this helps.

Ryan, ask the guy doing the removal if he's going to get the "funk", and if that includes the cosmoline. These cars come with about a ton of this crap (looks like butterscotch, caramel, like you landed on a Twix factory). I spent serious time under my de-engined car with a drill and a wire wheel breaking off the thick stuff, then a toothbrush and a case of carb cleaner getting off the residue.
My pressure washer didn't even TOUCH it.

As for stuff to mask or otherwise protect, definitely the tranny breather, Hal flywheel sensor, CV boots, brake calipers (piston seals are loaded one way and pressurized water can get by), ... are you going to drop the tranny belly pan?

Unless it is a concours or track car, leave the cosmoline
