Clean up a engine. shot/bead blast???

[drunkn munky]

I have the engine removed from my NC35 which is looking pretty grotty. I wanna clean it up and then paint the casings so whats the best way to do it? do i get the scrubbing brush out with some sort of cleaning solution or do i just pop it down to the shot blasters and let them take care of it?

Clamp all the hose ends, tape up all the inlets and stuff (basically seal it up)... then hit it with a steam cleaner.

That'll blast the very worst of the crud off it (inc. loose bits of paint, etc)

Scotchbrite pads white spirit and some patience.

shot/bead blasting is too severe, and will be awfully difficult to protect vital machined surfaces.

I dont want to hijack your thread, but i posted some pics about my current project with some details of the guy that vapour blasted my stuff.

if you need any more info/photos, pm me.

the engine has to be stripped down though.

I was about to suggest vapour blasting but billysbones beat me to it. I've used it myself and it works an absolute treat. You will need to ensure that the residue is thoroughly cleaned from oilways etc. Unlessyou can screw blanks into holes the likelyhood is that any other kind of masking will get blaasted away, it's a pretty high pressure system.

That'll be Methyl Ethyl Ketone Peroxide then. I thought that was a banned substance, or is that Trike (Tricloroethane)? Fuck me, yeah... you don't want to work in "an enclosed environment" with that shit, you'll get the heebie jeebies alright!

I've used scotchbrite/pan scourers, parafin, followed by brake cleaner to degrease, with good results.

If it is metyl ethyl ketone peroxide, be extremely careful not to get it on your skin. It burns like a bastard. Not straight away though. got some on my overalls without knowing where I used to work, and it burned all my torso. still got some scars from it. usually used as catalyst for resins.

wouldnt use it on ally, would probably damage the surface.

If you get it blasted it wants to be `nut blasted` crushed nut shells are used so if it gets in the oil ways etc. it desolves and wont trash your engine

I worked with MEK inks for a while. Nasty, nasty, stuff. The test lab had extraction fans like you wouldn't believe because it's one of the most carcinogenic substances on the map I believe.
