Last Saturday, I had breakfast with John Walker and he warned me about the possible consequences (head damage). I would not doubt this knowing his vast experience.

But here's a tip for those who are planning to tempt fate for just a few more summer miles.....

I found that if I *retarded* the ignition timing a few degrees, I could drive the car as hard as normal. This, *without* inducing the dreadful "pinging" noise of the head slapping the cylinder.

My mechanic suggested what I was doing in reality, was taking a bit of combustion pressure off the cylinders. It works, and although the retarded timing takes some snap out of the SC's acceleration, I can easily live with that for a little while.

See above - I found this message in an old thread that suggests that one may be able to minimize physical damage from driving with broken studs by simply retarding the timing to stop the dreaded "pinging noise" of the head slapping the cylinder

Has anyone else tried this?

Thanks,
