Hi
I have a GSR block that is super dirty and Im trying to get it super super clean. I want the block to look brand new, as if it came straight from the dealer. On the inside of the block oil has stained the aluminum a nasty brown color, and the outside is covered in old oil and grease and residue build up. What can i do?

 

alot of people on here have spray painted with that hi temp paint with good results, just get the aluminum color. Your best bet is to get it cleaned by the machine shop first and then hit it with the spray paint.

 

can the machine shop remove the oil staining from the inside of th block/head? can they remove all the grease/oil build up on the outside?

 

yes they can...its most offend refered to as hottanking...basically the motor goes on a rotating stand and is washed in a huge parts washer w/ degreaser and other chemicals....you still have to go at it w/ some sanding if you want it to look good...bottom line tho no motor is gonna look brand spankin new...

 

your answere is...yes they can...but it costs lol when i had them clean mine it cost like $50 or something...not that big a deal....if your that worried about it...go buy some "awesome" at your local 99 cen store, and go to town...i promise it will take most of the crap off

 

I have soaked the entire block with engine degreaser 6x. I then sprayed on laquer thinner and mineral spirits. I have doused this thing with so many chemicals but still no show quality finish. Im just gonna bring it to the machine shop. I have put so much time into cleaning this stupid thing, I just dont understand why the crap doesnt come off!

 

bead blasting makes it look new

 

yeah hot tanking alone wont make it look all the good...bead blasting is the best way to go about it
