Title: Heat shield help
Post by: 91 ECO on September 19, 2006, 05:17:52 am: I am in the process of replacing my injectors and I have one heat shield that will not come out. I searched here yesterday and have tried to heat it up with a torch with no luck. I have also worked on it with a pick several times. I want to exhaust all other alternatives before trying the compression method. Any ideas?? How much can I heat it up with a torch before it's a problem?

Thanks,

Mark

Like a ghetto slide hammer effect.

If you mean your vise grips are slipping off the end of the screw when you hit it, well dunno what to tell you. Try a different grip right on the screw head, and use genuine Vise Grips, the generic ones are't worth a damn.
