What's the recommended procedure for cleaning a computer controlled engine? In my case it will be a 1.9L Escort W/ EFI. I just picked up the car, and it's definately got some oil leaks. I'd like to clean it up so I can find where it is leaking from. Would it be considered safe if I-
1) Drive down to the local coin-op DIY car wash on a rainy day (won't be busy).2) Prop the hood until the engine is only warm to the touch (~30 minutes)
3) Using saran-wrap/zipties/tape, cover the Alternator, Distributor, PCV valve/inlet, air inlet (if exposed), and any dipstick tubes. Fwiw, it is only the sides of the block and the transmission bellhousing that are dirty, and that is where I'll concentrate on- no blasting water around the engine compartment all willy-nilly.4) Spray down the grimy block and transmission case with Simple Green and let sit for 10-15 minutes.
5) use the "Engine Cleaner" selection in the car wash, but ONLY in the low-pressure mode (IOW, use the gentle stream, and don't pull the trigger)6) Use the Rinse selection in the car wash, but (once again) do NOT use the pressure.
7) Immediately uncover everything I covered and start the engine, allowing it to come up to operating temp.This is pretty much what I did on all my older (non-computer controlled) cars with great success and no troubles. Any help or suggestions are appreciated.
Thanks
