Fist off I would like to keep it the factory color. Does anyone know what that would be and where to get some? Second what would be the process? Just a Good cleaning and then just paint? Or should you try to remove all the old paint first?? Thanks for any input

I have a feeling people will say degrease it. If they DO, what kind ?

TPD1990

purple power, simple green, zep ISD, ramsys power bolt, bleach, dawn, brake clean, and a power washer

If you have access to a steam cleaner, that's what I'd start with, assuming you don't have any fuel lines or anything still on the motor that could be damaged by the extreme heat.

What color are you thinking about?

Once you have it degreased I'd try to wash it down with laquer thinner,
blow dry, then a coating of epoxy primer, then paint.

I just pulled my engine and trans out due to blown rear main. I seperated the three (ctd,727,us gear) Compelly degressed and steamed cleaned. I used Lianda 217. Its a comerical degreaser we use at wrk. It will make the alumium all foamy and shiny lol. Then i painted the majorty of the engine Cummins ISX red. Then pulled misc. parts off and painted them high temp super gloss black. Injector lines got some metalic silver. Then once it was all painted and back together i put new gaskets in everywhere. I like the look of new felpros hanging out everywhere. Before i painted i used paint thinner and or barake clean on the entire engine. I bought the ISX red at Cummins northwest. That Cummins paint aint cheap. They had any and every color a Cummins has ever came in. Bege, black, grey, red, that weird yellow color. Ill make a thread on the whole project when i get some time.

Sorry bout the quality of pics. Stupid Cell phone camera!!

I got the Cummins Beige at Napa in a ceramic engine paint. First I scraped all the heavy crud off then washed the block with Napa brake cleaner & then power brushed all the rusty areas to bare metal & washed it again with the brake cleaner then painted it.

You guys have more patience than I do. I'd probably clean it up real good, but then do what dodge did and break out the black poof cans...lol

I do have to agree that you need patience to prep and clean an engine when going to repaint it. I mean first off you definitely want the paint job you do on the engine to last for a long time, as good as from factory if not better. Cleaning the grease and/or caked on oil off the engine is the first step, then clean with a good, commercial cleaner or laquer thinner, and then clean up any rust spots/exposed metal areas of head and block down with a wire wheel on a decent sized 1/4" collet grinder. If you get it down to the bare metal looking surface, clean again, and go to then paint your set number of coatings on it will turn out like brand new. I know one day I'm going to have to pull my engine out to do this and one thing I'd recommend is to stay away from using the Cummins black paint as it defeats the purpose of being able to see possible oil leaks down the road. Black paint + black diesel engine oil = NO I don't think I'd ever decide to use black as a paint choice on a diesel engine just because of that reason, but just my opinion. I plan to use the Cummins red paint that dstad used and what most all new Cummins use (even the ISBs) in the trucks today.

oven cleaner works real well to get all the gunk off the engine. Thats all we used in college when I took a engine specialist class. It will even take the old paint off and if it doesnt come off with the oven cleaner then it on there good so just paint over it.
