Cylinder cleaning

[Flanderz]

Hi guys
Well finally got my head off and have sent it to get cleaned, crack tested & milled if needed, was looking at my cylinders & pistons and they are very very dirty, alot of carbon build up (212Ks on engine, never had a head gasket change). I was wondering if there is a way of giving them a clean wiothout having to take the pistons out or removing the block from the car. I was told that mabey a buff on a drill would help but is there any cleaning products that I could use etc to get off the carbon???

it also helps preignition ( which isnt good either )
dont touch your cylinders, but you can move the crank to TDC for each piston, so the piston crown is right up the top of the deck, you can use a wire wheel on a drill to clean the crown of the piston.

if you have the head cleaned, if you can aford it get the valves lapped in or reground. dont forget to adjust your tappets, and this thing should run so smooth you can balance a 50c coin on the rocca cover.

Using a wire wheel to clean your pistons can cause hot spots.
You could just buy a can of throttle body cleaner and spray it on, then wipe off with a clean rag.
While your at it, clean the inlet manifold and throttle body of excess dirt/carbon/sludge. Available at Auto Parts Stores or BIG W.

can it be used to clean other internal components such as camshafts valves rockers etc?

What would the best thing to use to completly clean a completly bare head?

I just brought a head that i want to rebuild. The OEM manual tells me, "prior to reinstalling, clean all the parts in solvent, dry them and apply lubricant to any contact surfaces" Im just wondering what solvent would be best for the job.
Last thing id wanna do is put it all back together without cleaning the parts of any crap that may have gotten onto them 1st..

Edit: Im looking for a solvent to actually bathe the parts in, not somthing in a spray.

Large washtub full of kerosene does the trick and it also stops rust build up as well.

on some older engines its the carbon build up that is holding the thing together and keeping it with proper compression. Probably increasing compression and giving it more HP than from factory lol
