Hello Guys, I am new to the forums and have a question.

I have my cylinder head off to get some work done on it. I noticed that the top of the pistons have some black sooth kinda stuff sticking on it? Should I clean this before I put the head back on? If so then how should I do this...a brush and a vacuum? There are bunch of holes next to the cylinders and I dont want any crap going in it.

Thanks, I appreciate any help.

 

stuff paper towel in the holes and use carb cleaner and a lint free rag to get the buildup off..

But if its not to bad then id just let it be

 

Ps: dont spray the carb cleaner on the piston, spray it on the rag

 

if its off the car, shops can blast it with walnut shells i believe....vinigar also may help but make sure you neutralize the head when done with the vinigar with baking soda and water.

 

i think youre not supposed to clean the pistons because it gives you higher compression with that shit still on them lol??

 

Thanks guys will try the carb cleaner and rag thrick this weekend...
As far as getting higher compression with the crap sticking on the pistons...makes sense man!!!

 

stop putting stupid ideas in peoples head. not calling anyone stupid, just saying that many people are gullable and will start to think about putting crap in their chambers to raise compression.
