Damn this carbon crap won't come off!!! Pistons look like ***, combustion chamber looks like ***....valves need work (probably just replace).

 

What have you tried so far?

 

Toothbrush and engine bright.

I am thinking wire brush and Simple Green but want to make sure the wire brush isn't going to screw anything up.

 

use a soft wire brush and a dremil.
it'll be nice and shiny when u are done

 

Valves may just need reground if they aren't burnt or bent. since the seats need reground its cheaper than new valves you may not need. as far as the head get a shop to hot tank it. if you are doing all that work anyway

 

get a good old can of carb cleaner and just spray it on and let it soak for a while then wipe it off, repeat as necessary.

 

If he is doing valve work nothing will get it cleaner than a hot tank. then all he has to sweat over are the pistons.

 

GM top end cleaner works great

 

any rough quotes on a hot tank?

 

Acetone form home depot and a small metal brush...

hope this tip was helpful

later

 

Gabe, soak the combustion chambers in some heavy-duty degreaser overnight. In the morning use hard toothbrush & scrub that gunk away. Look @ pics that I've sent you. Exhaust valves are a BITCH! Get a dull knife & start scrubbing it away. It took us about 1.5 hours just to clean the exhaust valves. Try NOT TO SCRATCH the valve' steam!
