Hi Benjamin, THanks for your advise!, But I need to know a little more :) What is a left hand drill bit set??I suppose the spiral on the dril goes counterclock wise then, but what are the benefits then?
Ofcourse pulling the head is the safest way, but I don't like to pull the head of an otherwise sound engine..
BTW, what is an E-Z ???Yes, the job is making me a little nervous but if I screw it up I can always pull the head and bring it to the machine shop for extracting the studs.
But I think I should try it myself, don't you think? Thanks, Robert----- Original Message ----- From: "Benjamin Breyer" <bmb2102@xxxxxxxxxxxx>

Pulling the head is the safest way to deal with this problem. If the job makes you nervous, let a machine shop extract the studs. It isn't that difficult, however. Use a *good* drill bit set, starting small, and gradually step up the bit size until little more than the stud threads remain. Then use an E-Z out, need nose pliers, or something else. If you measure the depth of the stud hole, you needn't fear drilling too deep. You will probably feel the bit bottom out before you begin drilling into the head anyway. I've never used them, but a left-hand drill bit set might be a good way to go. Quoting Rob van der Es <r.vdes@xxxxxxxxxxxxxxx>:
Hi Paul and the rest of the IML gang, I need some expert advise with regard to the exhaust manifold studs of my 1960 Imperial. For 10 days ago I broke the exhaust manifold flange of the left manifold... I noticed a a roadbump too late and was hitting it with too much speed, since the whole exhaust system is pretty rigid the impact was given directly to the cast iron manifold.. With the restult that the flange has broken.. I found myself a reputable cast iron welder that has done the job many times before so with a little luck I will have my manifold back early next week. But now for the real problem: when taking the manifold off two studs were broken.... Despite of several overnight soaking sessions with penetrating oil! The number two stud (counting from the radiator) and the last stud are broken and almost flush with the head. Ofcourse I can try if the 4 remaining studs and bolts will secure the manifold but I simply don't like the idea. On the otherhand, I either don't like the idea of taking the head off. And at least the last stud is very difficult (or not..) accessible with the head in place. So maybe I should aim for the second stud to come out. Both studs are almost flushed with the head surface (slightly below actually). Is there a safe way to get them out? Or should I try to secure the manifold with the 4 remaining nuts and see what happens? If this doesn't work out, how do I remove those broken studs then? And where can I buy new studs for my engine? Ofcourse I can try to drill out the number two studs since I think I can access this one from the left front wheel area (with the left front wheel removed ofcourse). But what if I screw up and the studs doesn't come out, since these studs are in the cooling fluid area it is important that I don't cause any leakage. If I break a drill for e.g. while it is just through the center of the stud (if I am lucky..) and the broken part gets stuck, cooling fluid will escape then!! So should I go for the 4 studs fasting method first? Any words of whisdom??
