After breaking in the cam last night the freeze plugs on the passenger head started leaking. The rear plug leaked for about 30 seconds and then stopped but the front one was spraying out of a small pinhole leak. I ended up replacing the front freeze plug. I'm considering putting JB Weld around the edges on the rear plugs to help seal them. I don't want to tear apart the top end at this time. Do you think the JB Weld would be a good solution to my problem?
