had a camshaft sprocket fail causing an oil leak and an oil soaked timing belt. so, overnighted timing belt kit and bde intake camshaft sprockets. during installation, apparently the sprocket wasnt aligned with the dowel and i ended up driving the camshaft dowel in too far. any suggests on removal? i thought about possibly drilling and tapping and pulling it out, but it doesnt have much meat. am I stuck replacing the entire camshaft?
