ok, I have 4 dirty motors that I would like to clean.
Motor 1 is a 93 L67 that is in my car currently. What should I use to clean it with, and how should I go about it?
Motor 2 is a 93 L67 with no SC that is out of the car. Motor currently has a spun bearing, but I'll probably be rebuilding it over the summer so it'd be nice to have it cleaned up to work with.
Motor 3 is a 94 L67 complete minus coil pack and alternator. Currently on an engine stand. Complete wiring harness attached. This one is a running pull that I will not be rebuilding before using, so extra care will need to be used here.
Motor 4 is a 17 Buick 350 with 2bbl carb. This one is COVERED in oil and dirt. it'* made the garage very messy, but was a good running motor when pulled and turns over well now. This one i would like to clean up some to try and sell. It is also on an engine stand and complete oil pan to carb.
I probably should clean the B18C1 in my Integra too, but that'* getting driven so it'll get dirty again faster.
I have never cleaned/degreased a motor before, nor have I heard of people doing it with the motor out of the car. What products should I use? Anything I need to be careful of? Motors 3 and 4 would be done first as they are here with me.
All Help is appretiated. Thanks.

I use Simple Green Max. Works very well espeacialy with how dirty my Jeep'* engine get'* from wheeling.
Cuts through grease and muck and I don't have to worry about it eating paint or plastic. I buy it in the gallon jug because I use it for various other cleaning duties like rims, tires, vinyl siding, ECT

It won't hurt powedercoated parts like heads and engine blocks.
I use it to clean many types of plastic car parts. It cuts grease great.

Thanks, I'll look into the simple gren max and the castrol stuff when I get to the store next (still need to wait for it to warm up again)
Now, for the motors on the stands, should I do anything special before cleaning them? I assume I need to cover all the oprn coolent and oil ports, but if there any other things I should be careful of?
