I'm replacing my clutch cover with a spare one I polished up. The polished cover has one of the dowels stuck in it and the corresponding hole on the engine side also has a dowel stuck there. I'm trying to remove the one from the clutch cover to avoid buggering up on the engine side. At least I can use the original cover if I somehow screw up the polished one. I've tried penetrant and tapping with a hard plastic mallet to no avail. I even tried to grab the dowel with channel locks with a little padding between the jaws. I have a spare dowel so I then tried to grab the bare dowel with the channel locks. No luck. I also tried tapping straight down on the dowel to shock it. The cover is now laying "dowel-side" up with PB Blaster soaking down into the hole (hopefully). Anybody know any tricks for this?
