take care ---LA
</TD><TD class=alt1><!-- message -->"Driverno8 I am quoteing you here
"The #5 cyclinder was burnt so bad that a chunk of the valve broke off and rattled around. "
I am offering my humble opnion on this issue with no hostility
I am A marine engineer and work with large inline diesels with bores around 20 inches I have seen this happen before on these in line engines, what I think happened is that the #5 Valve broke first, my guess is it was the Exh valve? what happens next is the injector is still putting fuel into the #5 cylnder but with the exh valve broke compression will not happen, so the unburned fuel/ air mixture is pushed into the the Exh manifold an throws the whole cycle off for the other cylinders that fuel burns in the exh manifold thus causing the 2 closest cylinders to over heat that is why your pyro did not reg any thing wrong untill after the fact. if you had an alarm for high Exh temp for each cylinder you would have seen #5 go first #4 go second then # 6 go third this happens very quickly, the large engines that I have seen this happen to turn at 580 rpm and are a 4 stroke diesel as well from the time you lose the first valve the whole thing takes about 10 seconds before the the built in safetys shut the engine down this is at 580 rpm, I have seen this first hand twice last year while I was the engineer on watch aboard the ship I was working on. you were driving your Cummins
at around 2000 rpm you could cut that 10 seconds down to about 3. 5 before your engine had the melt down. and just like the rest of us you probally had your stereo on and highway noise none of us could have time to react before it was 2 late, I am not familar with the banks kit and as I understand it it had a safety system to tied to the pyro to shut down or to change the timing to cool things down if the temps went to high this whole thing happend so quick and the temps went up so fast that this system probally did not even have time to react before it was 2 late and like I said I have seen this before and on this equipment we have event loggers that log every thing and after the coast guard comes to investigate I have become very familar with this type of casulity and what happens. one mans humble opnion.
please do not Flame me as I am only offering a different perspective
good luck
