Shop never sonic checked the walls beforehand?

its my opinion anyone with a CNC has to allow for some type of variance regardless. A "take it to the limit" CNC program is only asking for problems imo.
Bad situation all the way around.


I think his point is that, agree with it or not, that 30 sets of heads were run with no problem.

His had a core shift problem that the CNC simply exposed.

That the heads should be replaced because of the core shift problem regardless how i was discovered. On that basis, he does have a strong point.

If a product has a KNOWN underlying flaw, regardless of the method of discovery, it is incumbent on the manufacturer to make it right. It's not as if this is the only set that ever core shifted.

I understand AFR's point, I'd make the same one, but after consideration, and a night's sleep, if the problem was known to the manufacturer, regardless how he found out, it should be replaced. Their position has no merit.


There are really two core issues at hand here:

1.If the core shift was discovered BEFORE the CNC was put to it would anyone argue that it shouldn't be replaced? No, that would be silly. It would be a defective product. This is NOT about breaking through the wall of the cyl with a CNC, it's about core shift.

2. The other question needs to be asked is did the CNC CAUSE the core shift. I have not heard that argument, and that would be hard to make.

In my court, I'd rule for the plaintiff, replace the fkn head you cheap bastard. This was a known problem with many heads, no one has argued that core shift hasn't happened. The argument made by AFR is a straw horse. It has nothing to do with the core sift condition that existed before the head was put on a machine.

The ONLY question is was there core shift or not, seems to be proven there was. End of story.
