My bell housing had years of oil slung on the inside and then it sat for years. I tried soaking it with gunk (several times) and a pressure washing it but you'd think I was never there. Any suggestions on getting stubborn grease out to expose the shinny metal underneath?

I used dollar store oven cleaner on engines before and it worked very well.

There is always mineral spirits and a wire brush.
 
I use my pressure sandblaster after using a putty knife to get most of the junk off. Gar Williams
 
I just cleaned one.

Started with some safety clean to get the loose stuff off.
Then some Plain old hand scraping.
Followed by some time in the glass bead booth. I have scrapper in the booth and scraped some problem areas cause it can take forever to get some crap off the metal.

I like to do manual scrapping at times cause it just goes faster and does not need nasty chemicals.
 
After scraping with putty knife & wire brush, apply water based POR 15 "Marine Clean" mixed with "hot" tap water. With coarse steel wool, rub greasy areas with 1:3 mix of "MC" to 3 parts "hot" water. (Wear rubber gloves). Solvents & mineral spirits will melt grease, make grease thin, & allow thinned grease to penetrate porous metal. "Marine Clean" will emulsify grease & remove it so one can see bare "cleaned" metal.
 
Easy-Off oven cleaner works great for this!

You can also bake it off: Put it an oven, and run the self-clean cycle. It will definitely work. When the fire department arrives, they will be fascinated.

You are all going to think I am crazy (that's the general consensus anyway)but, I use a weed burner from harbor freight. I just hook this up to a bottle of propane and start blasting whatever I am cleaning. I most always use it on cast iron but it works well on steel but I stay away from aluminum. I heat the part up to about 350 degrees and let it smoke till it quits. Once the part cools I blow it off and scrape the worst off then pressure wash it. The burner is 29.95 and a tank of propane will last a long time.
 
I sure do appreciate all the good ideas - I'm going to try the oven cleaner and then the marine clean - and Doug - you just plain cracked me up - I read your advise to my wife!
thanks all - this weekend I'll dive back in
 
close to what James said I use a torch don't hit the oxygen this burns the junk off then just blow the burnt dust off works every time

Yes sir, and if you're crazy, then welcome to the asylum. I use either my acetylene torch (low flame) or a propane torch. God I love the smell of smoking oily crud in the morning. :D
