Do you think the rings are in there tight and not expanding? Hence the solvent in hopes of breaking them free? Kind of a two edged sword here. They may come free but then they may really be loose and your compression would get worse. Being where you are kind of rules out thicker oil now doesn't it. Could you get the pistons down in the cylinders and try some ATF? That stuff has a lot of detergent in it. Are you close to an oil change. Someone on here mentioned that they run a quart of ATF for the last few hundred miles in there oil before changing it. Perhaps that might help from the lower end. But in all reality the tops are where the coke is at most times.If you already have the head off then aren't you half way home on doing the repair? Or are you stating the cross hatching in the cylinders from your memory when you did the valves?Bummer, but a kerosene soak and ATF in oil combo might get some results. Do let us know.
Yeah 78mm is pretty bad haha.So I'm looking at getting a ring groove cleaner since I'm tired of using screwdrivers and little files to get the carbon out.Does anyone know what cutter sizes to use on these things? I don't have it apart yet or I'd check.

I don't have it apart yet or I'd check.I have on occasion broke a ring in half and use the butt end to clean the ring grooves.
I have used both and I really like the results of the proper tool. I tend to twist the broken ring about too much and that ends up scratching the groove in not so pleasant ways.I'd hit O'Riellys up for there equipment if it available. My guess it that they will have a hand held part and an assortment of teeth or something to put in to get you to the proper size groove. You basically buy the tool and get your money back when you return it. No return then you just got a new tool.Helps do the job and keep the clutter off the wall over the work bench.Try it.
That's what I'm trying to avoid is scratching anything, getting it clean faster is a plus too.I don't have anywhere local I can rent from but I can buy it for $20-$35 depending on brand. Thanks for the reply.
Is it recommended to change the rod bolts everytime?
