Cleaning Engine Sludge

1. The engine is off the bike. The crankcase is split with the transmission / drive shaft / shift drum / everything taken out of it.

2. A couple of days ago, I soaked the crankcase halves in some Murhphy's Oil Soap.

3. Now, there is slick sludge in various places on the CC halves. Inside and out. In corners and on surfaces. I'm thinking it's something like molybdenum mixed with the oil and soap. It's white/greyish.

4. It's very light in viscosity. But, there's a lot of it and it's in nook and crannies where I can' reach with a toothbrush or towel. Using a pick would take a long time.

What's the best and fastest way to dissolve this slime from the crankcases? Something that'll clean out the oil passages because I have a feeling there's a lot of the stuff in there. Are mineral spirits going to strip the engine paint?

I've heard Pine Sol is the go to cleaner for engine parts. Haven't tried it, but I've seen pics and things come out gleaming.

No - that will effectively dissolve aluminum.

Try the PineSol first.

Murphy oil soap, that's to clean wooden floors, not much degreasing power.

I king of object to some of the above suggestions, Caustic Lye products such as hot tanks or oven cleaners, really bad for aluminium. But I can be patient and don't have a problem picking at stuff for a long time.

Go buy some Castrol engine cleaner/degreaser at CT.

if petro products don't work try paint stripper... it has methyl chloride which one of the really good cleaners we used to have in the old days, but bear in mind there are reasons it isn't used for that anymore... like it's pretty evil on your body. I brush it on and cover it with plastic sheet to keep it from evaporating

if you buy "gasket remover" in a spray can thats all it is... paint stripper

Easyoff is ok on stainless steel but be careful on aluminum... it can eat alloy

How do engine rebuilders clean oil from aluminum?

Machine shops/rebuilders do hot tank iron blocks and heads in a mixture of water and caustic soda. Caustic soda is lye and it quickly eats aluminum. They have solvent tanks for aluminum. A million years ago you could buy a similar solvent product called Hydro Seal. It would clean baked on grease and take carbon off pistons and aluminum heads with an overnight soak. I used it on a Corvair rebuild (nothing but aluminum!) Hydo Seal is gone now (another toxicity victim), and replaced with Hydro Seal II, which the Internets seem to say is a disappointment, although I haven't tried it myself.

They make special bake ovens. They also make some really heavy duty dishwashers. And some high wattage ultrasonics are very popular.

There is no single solution.

I used Pine Sol on some carbs I was rebuilding. Did an outstanding job. Definitely my cleaner for smaller parts.

Spray wand at the car-wash, hot soapy water. Have WD-40 WITH YOU to stop the IMMEDIATE rusting on the steel bits.
