Default Header Clearence Issues...

Okay, this is a bit old but I figured I would post it on here to get everybodies input on this.

A few years ago I had some Jet Hot LT headers installed on my Camaro. When they were finally installed, they cleared the K-Member literally by about a few millimeters, and when it was cold outside the engine would torque over and a nice tapping would eminate. Of course this always got a few looks so I would usually pump the gas so the engine would resonate and the tapping would stop.

Well, finally, after a few years of doing this I finally got tired of this and I took it to a shop to have it inspected. Now this is maybe a year and a half after the install, and they still tend to tap in cold air on a cold start. However, when he picked up the car it looked like one of the headers were actually in the process of "clearing itself" It was making contact with the K member, and you could see the small notch where the header had dug in.

So my question now is this. Should i attempt to somehow seperated and tighten up the system, regain the gap, and wrap the header? Or should I just not ever screw with it since the header is notching it self out anyway. I don't have to worry about the primary opening up... do I?

If you did poly motor mounts that would fix it as well. When i did my headers i had the same idea you did in that it will work it self enough clearance if i had no notched the k member enough. It would be pretty difficult to split the primary with it only hitting ever so slightly.

So that is the reason it taps? Because the motor actually torques over when its just really cold? I figure that is what it is, and once it warms up to operating temp. I just can't see myself putting the manhours into something that is a trivial nuisence at most.

What would be installed with poly motor mounts? What benifits would I see with that? Would it be possible to do that without taking the engine out? Im new at this.

Dropping the header and shaving a little bit off the kmember would take all of an hour. It should have been done when they installed the headers.

Grind that ****. Better yet, remove the headers, put in poly motor mounts, AND grind the ****.
