Re: Hear boiling coolant from water pump / top hose
Actually it's a long block. I don't know what would have caused this, but at least one is leaking. I'd be very surprised if they used non Alliant cups. They really do go through a lot to build these blocks. The heads alone go through some kind of vibrating media bin, vibration plate thing, and cryogenic treatment. Three angle valve treatment, Stellite valve seats, and valves, 910 springs, and they were installed on the block with ARP studs.
Why they would fail in 1000 miles, I have no idea.
