While winterizing I pulled my port valve cover to find a lifter that isn't pumped up solid, Im able to push the push rod down a tad (1/8" or less). My question is what oil do you run? I talked to Bob Madera this morning and he said the 25W40 I'm running is much to thick for these Johnson lifters and thats most likely my problem. I was just following the specs from the manual. Me and him also made a connection last spring, I believe he was working with you the same time I was ordering from him and calling him daily for questions, small world. I told him I'd call him back to go over everything again so I can work this out, he gets pretty technical so it may take a call or two lol

I had a collapsed lifter on one motor about a month or so ago, but that was most likely the result of too much spring pressure from the springs I used when I did the top ends in the spring. I will be changing the springs again this winter to a spring with less seat pressure. I used to use the Merc. Synthetic Blend 25W50 oil but I just started using Valvoline VR-1 Racing Conventional 20W50. Probably only have one or two more runs and then I'm done for the season. So sad..
