How to repair a crack in cylinder head?
Has anyone had to repair a crack in a cylinder head before with JB Weld? The crack is under the valve cover between the rockers. Just wandering if it is probable for the JB Weld to hold, and exactly how to do it properly. I bought the head from a junkyard to replace the one I have and have done a good amount of work to it before sending it to a machinist who found two small cracks. He said the two cracks are shorter than an inch long, and probably not enough leaking through for it to have shown in the oil. I would appreciate any information on how to best fix the problem from those who have had similar issues they have dealt with. Thanks, Don
