When reassembling the valves should I lubricate the stems/guides? I believe the answers is Yes based on the few threads I found. What lubricant should I use? Is engine oil (20/W50) alright to use or should I uses a fine oil like Singer sewing machine oil? I believe greases should not be used because they will leave residues that could make the valves stick.
