Engine cleaning

[MatRacer]

My engine is out and it needs a good cleanup!

I tried engine degreaser, but its not that strong... I tried a dremel with a the softer metal brush and DAKI --> it worked good, but I need to rinse it with water afterward which is not really good for when I will start to remove some parts...

What are your procedures?

spray with degreaser us toothbrush to clean it, rinse with water

atleast thats what i did with my m20

[flyboyx]

go buy yourself two or three cans of oven cleaner. let is sit for a while then rinse it off with a hose. repeat as necessary.

Acid:)

Acid:)

which product are you buying?

[416stroker]

I just take some of the acid degergent from my dads shop IDK who makes it. But fuck it cleans fast and will oxodize aluminium if you leave it on to long lols. Its probably a ZEP product scince everything else is there.

Im pretty sure this is it.

ZEP Heavy-Duty Cleaner & Degreaser 505

What about the effect on plastic and rubber? If I remember right, acid on plastic wont do nothing...

What about oven degreaser?

[416stroker]

Didn't hurt any plastic or rubber

Has anyone walnut media blasted an engine to clean it?

i bead and walnut blasted my valve cover to repaint it. (obd1 style where the factory paint is always messed up) it was mostly just to see if the pos harbor freight blaster gun would actually work and it did, but it clogged regularly and used a lot of media to get it done. next time i blast something im going to try a cheap diy like these guys:

and after that probably end up buying a decent blaster

Carb cleaner works very well.

I recently purchased a soda blaster unit from Harbor Freight.....it works well, plus the cleanup is easy. Just make sure you've got a well ventilated area to work in.

It cleaned up my M52 for the swap quite well. Just my .02 cents.....

The formula is scrape with a screwdriver all the reallllly grimy stuff, then spray on any degreaser, wire brush on a drill/die grinder, wear eye protection, use brake cleaner and paper towels to tidy things up once 95% of the dirt is gone, high temp primer, gaudy color. WOOO



Oil pan and front cover I'm using as masking tools now, they will come off and the pan will get replaced with e34 and front cover, valve cover, pulleys, fasteners, everything that unbolts basically will get powdercoated

I've tried oven cleaner on plastic and rubber, no damage.

Then I cleaned my engine with it. It degrease for sure, but it leaves a kind of white residue...
