So if any of you remember reading about this last year, my 12 year old son picked up a barn-find 78 Calais with 62,000 miles that had been sitting in storage for the last 20 years. Gonna be our father-son project. Very good condition. So we drained fluids, replaced all the brake parts, put in new tune up parts, etc. The kid really busted his a@$ all summer. Finally fired it up last fall. Runs and drives great. The only thing I can't remedy, is one collapsed lifter in the 260. I even ran a bottle of Marvel Mystery Oil in the oil. Just can't get rid of the " tick tick tick" under the drivers valve cover. This is his project and he's on a budget so a cam/lifter swap isn't on the immediate horizon. Not sure how much longer I dare run it this way though. Any thoughts?
