i just bought a gsr long block, and i took apart the headers. its really dirty in there and i was planning to take apart the head. i was wondering if there is way to clean it? some sort of spray? tools to use? can i use a rotozip to sand away the build up?

 

hot water bath and large diameter pipe cleaners

 

we are talking about the HEADER aren't we?

 

Use a wooden dowel or something dull to bust away the sludge and suck it out with a shop vac, as far as spray, use brake clean or carb and choke cleaner. Just dont smoke around it. lol

Fuel injection safe Carb cleaner or Air intake and throttle body cleaner (technical name for fuel injection safe carb cleaner)

 

Ok kool. but is it ok to use a rotozip to sand down the the head where the header is, its alot of gunk. oh yeah if i [plan on letting my motor sit in the back yard should i drain out all the coolant?

 

Don't sand anything on the inside of the head unless you are a trained professional. If it doesn't come off with carb cleaner and a rag, it doesn't need to come off.

If you leave a motor in your back yard, it better be covered really good. And yes, drain the coolant.

 

ok thanx, its away from the rain but in the patio covered with a tarp is that cool?

 

as long as it is not to humid (I'm guessing Kali is far from humid) it should be OK.

You may want to get some heavyweight oil (20W50) or some MMO or something, and put a wee bit into each cylinder and turn it over by hand a couple times. That should get a nice oil layer on the cylinder walls and prevent pitting if it is going to sit a while.

 

thanx for the info.
