This is a two question.
1. Check out pics of my b16a head at my site: http://www.imagestation.com/album/?id=4291860803
i don't know actually what wrong w/ it I need to get redone to it.

2. I bought a block recently and I found some black stuff on top of the pistons when you look at the top part of the block. I hope that I asked that right.

 

ttt

 

anyone

 

bump

 

you have to realize you purchased an internal combustion engine, so when you take the head off and look at he pistons, they are not going to be spotless. The black stuff is just carbon composite from the cumbustion of the fuel. Not sure if that is the answer you're lookin for.

 

1) i dont see anything wrong with it, maybe im missing somthing
2) yea its supposed to be dirty man, explosions happen in there. lots of them.
dont worry.

 

thanks kamin, what can I do to clean that **** off the top of the pistons.

 

gasoline and a lot of scrubbing

 

Take of the excess carbon with a brass brillo pad you can get at the drug store or supermarket.

You don't have to have the pistons 100% free of the carbon. It's not a bad thing if there is a thin layer. Can you say thermal shielding and combustion catalyst.

 

What safe to use to scrub it with?

 

Piston tops and combustion chamber. The brass brillo won'tt leave abrasive grit.

 

thanks guys
