Here's an explanation of whats going on: http://www.jalopyjournal.com/forum/showthread.php?t=589697 I'm seriously considering the oil passage redirection recommended in the thread. I know it's a janky ass sloppy risky procedure but I'm willing to give it an honest shot. But first, is it possible to (somewhat) clean out the oil passeges throught the lifter holes? I'm imagining fashioning some pipe cleaners with 90 deg bends and running them through the passages. Is this a possibility? I'm not a half ass kind of guy but if I pull this motor out only to have to halfway rebuild it im not puting it back in. I would rather build another engine, which isn't in the budget or forcast for that matter. So if I can clear up this problem and get a few more miles out of this thing without beating my valve stems to a mushroomed death I'm ready to try anything.
