Thread: Smokes at idle!!!!

A lot of the L67's crack between the valves and don't smoke. Pretty sure Scotty has some pics. I would check the valve guides you may have a super sloppy one that needs to have a new bronze guide pressed in or at least knurled. If it's sloppy as a few I have seen I wouldn't be suprised by the smoking at idle at all.

Its just weird that the two cylinders next to each other are doing this. They are Hinson ported heads and the guides were milled down I'm pretty sure to accept a larger lift in the future. Unsure how he does this but if they are leaking it sounds like the head must come off no matter what , then be sent out to a machine shop to have everything checked.

Post #148 shows what I think the issue could be.

Reading the first page I'm not very happy! lol. But reading post 148 a new crank does not make sense to me. My timing gear is chamfered.
