Top End Cleaner/additive???

With all this talk about leakage thru the valves when doing compression test, does anyone know of any effective additive/cleaner that can be used to clean the valves without opening up the top end?

Does using synthetic oil help? I know synthetic oil can be a good cleaner. But whether it reaches the top end.........?


(I had this in General Discussion)

If your oil is not reaching the "top end," dirty valves will be the least of your concerns.

Oil and filter hot and often are probably your best bet. I'm not really a fan of "snake oils," I think 99% of additives are junk. If anyone has had good experience with one, though, I'm open to hearing about it.

Not much you can do. Only air goes through the intake valves so there are no fuel additives or oils that can help.

A good Italian tune-up every month will keep the exhaust valves clean.
