I've accumulated some z6 heads and it's time to start cleaning them. One of the heads is badly caked in oil and varnished. I don't feel like taking everything apart to get it hot tanked so I'm looking at other alternative methods. I don't mind the elbow grease

 

I really don't know anything about cleaning engine parts but I would use simple green and let that baby soak for awhile then wiping it clean.

 

carb cleaner works pretty good

just bring it to any garage that has a parts cleaner and have them clean it up real good

 

get some JUNK engine degreser the foamy version works wounder and it will make it look brand new.

 

the bottom pics look cool lol

 

carb cleaner, eng. cleaner, brake cleaner...

 

Would it be safe to pressure wash it off afterwards after letting the engine degreaser soak?

 

ya that should be fine, but after your done degreasing them, spray them down with some light oil or wd-40 so that no surface rust/oxidation appears

 

brake clean the hell out of them its like 99 cents a can valuecraft from outzone

 

i like to use seafoam deep creep for the carbon build up.

Brakekleen works great too. definately agree with the oil or WD 40 to prevent rust.

 

sweeet I'll post up the before and after shots when I'm all done

 

I went to Wal-Mart and picked up some Engine degreaser and Carb cleaner. Spent less than 9 dollars. I ran out of carb cleaner and needed more I cleaned up two of the 3 heads since the other one didn't need it. Of the two I cleaned, one was deeply varnished and I couldn't really do much with it. What could cause it?

Anyhow, here are the pictures:

 

not enough oil changes lol, but i would just leave it or take the rocker assembly off and let it soak in degreaser for a little bit, that should take most of the tarnish crap off along with a steel brush or something

 

OIL THEM NOW, they will rust in less than 24 hours, I know from experience unfortunately. Especially if you pressure washed them off at all, the moisture will own those rocker arms with a quickness.

 

soak them in gasoline...it'll clean the **** out of them... just don't smoke when reassembling them

 

I sprayed it all down with wd-40 and covered it up Now I just need to find all these small parts I'm missing
