Water Leak question...

junkyardhero said

that sounds... tedious.

and kind of defeats the purpose, no? i mean, i understand wanting a specific type of securing washer, but wouldn't that entirely change the engineered properties of the fastener? less meat, less resistance, less clamp, etx, etx? (i'm not a mechanical engineer)

so i guess my question is why?

The purpose of the cupped washers on the slant 6 manifold is to allow the manifolds to actually move a very slight amount to keep them from cracking from expansion and contraction due to temperature changes. I wouldn't think you'd want a water pump to MOVE, but maybe he's found something new no one else knows about.
