Several of you guys on this site have been a lot of help. I thought maybe letting you know of a recent problem might help someone else out.
After getting our HiPo 289 running after it had been sitting around for ~25 years I noticed a sound coming from the driver’s side valve cover. It sounded just like a loose lifter. After checking the valve settings several times (with the noise still coming from what sounded like a loose valve) I luckily found the cause of the noise to be a loose oil baffle for the oil filler tube on the driver’s side valve cover. Don’t know if anyone else has seen this problem.
