hey i just wanted to check and see if the cylinder head on an h22 is made of steel or aluminum or something else? thanks!

 

Well Part of it's steel and Part of it's aluminum. For the most part it's an aluminum alloy.

 

alrighty. just trying to figure out whats the best way for me to clean out the cylinder head. i have a can of Gunk engine cleaner and i was wondering if that would be too harsh for the internals.

 

I'm not sure about gunk. I used a large container and Kerosene. I would imagine the best way would be to have it cleaned by a machine shop , but I'm too stubborn for that. I did read you shouldn't hot tank these heads. I'm not sure if that's true or not maybe someone who knows could chime in. I just wouldn't take the chance.

 

not true...i've had my head hot tanked twice....damn auto tensioner!!!!!!!

 

ill probably try the kerosene method, cause i do am too stubborn for than...

 

I had my heaed hot tanked for $20

 

What does hot tanked mean?

 

I'm assuming the head is off the engine? If so, kerosene is good. Use a toothbrush in some parts if you have to...

a hot tank is cleaning tank with heated solvent, they just let it set in there for awhile and the heat breaks down all the grime and crap and it comes out very clean.

 

get it hot tanked and soda blasted. It will look brand new!
