Hmm, acid and aluminium will make a nice explosive gas. Don't use the acid too concentrated (der!).
Uh, I don't know man, is it a really important engine? I'd make sure I didn't get any inside 'n' stuff.
becareful..... is it a case with magnesium in it..... if i remember correctly Hydrocloric acid and magnesium = Hydrogen = BOOM
You would be better off wiping it down with a solution of Caustic or Baking soda from the kitchen but wash it off good as it keeps on working
sodium hydroxide + Aluminium = hydrogen also........i would be very careful doing this. if do go ahead with it i would do it in a very well ventilated area. hydrogen is fine as long as there is no ignition.......its the ignition thats the problem lol:P
Why do you want to paint the engine case ///// it will only keep the heat in and not allow it to cool properly.
Clean all the crud off yes but dont paint the case.
sorry guys this is for the iron block v8
hmm cast iron, the acid will still etch into it, try kero and scrubbin brish.... but i wouldnt use acid...... cheers
yeah ,elbow grease ,a big bucket of kero and a scrubbin brish :P
sorry adz couldn`t help having a dig at spelling:thumb
or metho 
i think id use the kero but...only cause ive seen other people
do it and it came out good
some good degreaser should do the trick. the stuff from clints had 30years of grease runnign off my old kombi donk.
hey Pod....... (INSERT MIDDLE FINGER GRAPHIC HERE) it must be my mangled fingers, my typin is terrible...... damn wicketkeeping/ AFL hands lol
raflmao

harness the power of flammables and burn the s#it off!!!! whoosh!!! do it like the kombi on fire in chit chat section!!!! go out in style man
hhahahaha :P:P
