If metal in the head gasket potentially causes “Acoustic noise”…

I sure hope he don’t get around any chevrolet engines that had factory steel shim gaskets.

Might need ear muffs for those…

Ironically, that is the type of gasket that we pulled from this Motor and the noise was not present at that time when it was installed in this Vehicle.

Also, so far as we can tell with the garage testing of this Motor, the recent complaint noise is gone. Road testing to come will tell us how it sounds under load conditions.

I stated in a recent post: "that I thought that the reason we did not hear the noise through the old gasket, that we pulled, is because of its total metal content that had more surface area to clamp down and sandwich the gasket between the Head and Block. Just a theory to explain things, to get to the bottom of this last noise issue.

Apparently, the problem has been solved, we think at this time, so far in our testing.

The last thing we did was replace the Flexplate, so it stands to reason that it's out of round holes was the culprit after all and I may not have to rebuild the lower end of this motor yet. OfCourse this does not negate the other internal issues found by the forum. Which I am glad to be informed about, but saddened that they exist at all.

Like I said: Further Road testing is necessary to see how she does under load conditions.
