Default Engine Cleaning question.

There is grease or oil on the Valve covers of my '68 and I was wondering if just using a towel to do that bould be good or would that hurt anything. Should I wet the towel at all. The car has been sitting for 14 years and doesn't look like it will run in the near future so would water getting on the engine hurt it?

I'd cover the carb and dist. with plastic bags. Then spray down the engine with engine cleaner and let it soak. Maybe even hit it again. Do the top, sides and all over the engine compartment. Then use a pressure washer or good strong hose stream and hose off the grease and oil. If you do this out in the sun it will dry pretty fast. To speed the process along, use compressed air or the blow side of a shop vac. Make sure yoi blow out the alternater. Water will not hurt anything if you let it dry or blow it out.

BTW is a rebuild in the works or just waiting for the right time for the project? Good luck.

The best grease cutter I've found is simple green. Spray it on a clean rag and wipe off gunk.

If you wash it down, make sure you run it for a while afterward so the heat evaporates out all the water caught in the nooks and crannys. And make sure you bag the wiper motor too--someone here fried theirs getting it wet with a power washer.

I am going to go against the grain and say:
Don't do it!
I have a pretty beat up daily driver (I drove it like I stole it and now it drives like a stolen car!). Anyway, I got really frustrated when cleaning things, because oil prevents rust. When I would clean nasty old parts they would immediately rust or corrode in some way. Now I only clean something if I am going to paint it or know that it won't/can't rust. But thats just MHO

Two schools of thought, two discussions great. One other .02 worth - a clean engine compartment and engine makes working on it and looking at it much more enjoyable.

Simple Green (IMHO) is the best degreaser, and you don't suffocate in the process. :)

Well here is my 2 cents worth, from a guy who has owned a lot of greasy engines. My first choice is the Simple Green; it works well and is a lot safer than say oven cleaner. Don’t get me wrong, oven cleaner works real good if you plan on repainting what you clean, but keep it away from aluminum because it will destroy the finish. Here is a recent discovery though, I was cleaning up the engine compartment of a 2.8 Fi Z24 with a lot of aluminum and used mag wheel cleaner and was amazed at the results!
Another tip is WD40, never attempt to clean an engine compartment without some on hand!
(trivia.. WD40 = Water Displacement on 40th try)
Just my 2 cents.

Both Simple Green & oven cleaner will corrode aluminum (never use oven cleaner-it contains sodium hydroxide which is bad stuff on aluminum). Meguiar's makes a product called Citri-Gel which is gentle & still removes the grease & oil & is formulated for cars so it will not harm aluminum. Just saw in in use at a Bloomington Gold workshop. Only problem is it costs more. I still bought a jug.
