A bad day...ARP Rod Bolt Measure Stretch not Torque
So of to the boat ramp I went, CMD dialing in very well, accepting changes with the laptop then it got wet (salt water) and no more laptop.
Oh well I thought.
Went out for a blast on the new engine and threw a rod through the block.
Taken home now and pulled the engine in record time, just gotta strip it down now to see how / why it done it.
Looks like the rod cap has come off.

I feel your pain. If I had to pull he motor from my 04' GTX again, I think I could do it in 30 minutes.

What rods?? I'm assuming new rod bolts, if Carrillo rods they need to be stretched. Looks to be they were not tourqed or stretched properly

Molnar rods with ARP bolts. Everything was torqued up with a digital recently calibrated gauge, checked again the next day by me and my mate so they were done up as per the specs.
Need to get it apart for the full story.
When I gave up my old job of building / re-coning engines I had less that a 0.4% failure rate measured over something like 1800 units so I am fairly confident in my abilities. But you know you sit here and doubt yourself when stuff like this happens!
