Finally got frustrated with a rusted bolt that was preventing me from getting the cylinder heads off so I cut the damn thing:) Cleaned the pistons and am now cleaning the cylinders (and soon the cylinder heads)...what is the best way to clean them? A little sandblasting cabinet (careful not to get any inside the cylinder of course:), some mystery solvent that works wonders? Any help would be appreciated:)
Unless these are the special gold-plated cylinders, toss 'em and get a new set complete with rings and pistons. IMHO it's just not worth all the labor of a teardown to put the worn parts back in.

i will post you a pic tomorrow of what happens when a part "looks good", and you go with that assumption...it is much worse than what you will probably experience with pistons/rings/cylinders of questionable wear....
Neil, we all are/have been in your situation...first and foremost invest in a good repair manual...Bently, haynes, etc....there will be specs listed for wear limits in those manuals....you will need tools you may or may not have to measure the parts..(calipers, bore guages,etc)...after you determine them to be good or bad then you will know which way to go.....OR...you can say screw it, hope for the best and squirt some degreaser on the cylinders then scrub em with a wirebrush....rinse, dry, lubricate and throw the sucker back together... JT
Toss 'em?! Are you nuts and/or rich?:) There is little wear in the cylinders and the pistons look good too, plus the whole reason I bought the engine in the first place was to tear it apart and put it back together again (so it would run of course) I simply do NOT have the money to get new cylinders and pistons (we are talking over a hundred bucks right?). If in the future I want to go the 'new parts' route then I will, but for now my money situation is dire...as in I have none:( If anyone of you wants to buy me the new pistons and cylinders though that's a different story. Email me and I'll give you my mailing address:)
So, any non-purchasing solution to cleaning cylinders?
There is spray stuff for removing carbon from the combustion chamber and is usually just called COMBUSTION CHAMBER CLEANER... good for helping to clean out your blocked heat riser tube too!
Gotta be about the best suggestion for a good deep cleaning of those surfaces.
You sure don't want to sand blast them with sand! The heads need to be degreased with spray degreaser and high pressure water or hot tanked. The best to have an engine machinist check the guides for wear, the seats/heads for cracking, place at least exhaust valves then regrind/lap all valves. The pisons can be scraped with a putty knife and degreaser. The cyclinders need to be checked for roundness then the ridge removed (if one is there then best to just trash them and the pistons) then use tool to but the swirl/crosshatching back on the cylinders --- new rings properly gapped and positioned.
