found inlet valve on cyl. 2 stuck open, working on it pb and atf, using tie rod separator on each side of lifter and smack witgh hammer and valve snaps down but wont go down with spring only, seems to be getting easier, less of a tgap to seat. Is there anything better than pb blaste and atf to dissolve whatever is holding the valve from seating?.If i get it freed up what can i do to clean this engine up other than change oil regularly, additives?. cylinder 1 had no compression also just a blip those valves free, problems in cyl. two shouldnt affect cylinder one, i may nato have hade good connection on compression checking equipt.. anything else i could be doing to free up stuck valve other than what i am doing?
