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.

Castrol Superclean.. bill has got be swearing by it...

yup that is what i used when i stripped my parts car, It talkes dirt right off

Becareful tho....it will eat paint

and Plastic

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 will NOT eat plastic. I used it to strip paint off my plastic hood vents, and it'* revered by train modelers for stripping paint off plastic HO train models, and not hurting the plastic.

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.

I use Spray Nine and get results like



followed buy some amoral yes it is the devil but it dries nice under the hood

and coming from an avid car model builder The best thing to remove paint from plastic EZ OFF oven cleaner lol

ive always used simple green and oven cleaner... use the oven cleaner first to get the hard baked on greese off then use the simple green and some elbow greese to get he rest of it off.....

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?

Just to add, Gunk Engine Brite works really well too. Just use it in a ventilated area.
