well I haven’t complete tore down yet but I pulled plugs and they look normal and untouched, it’s cylinder 3 if you count from the front of the vehicle. The piston was still in there and I could push it down with a screw driver. It moved pretty freely. I can stick my finger in the hole under the mount and move the bottom part of the rod it spins around very freely on the crank. Also found a huge chuck of rod in my oil pan. I was on e46. What are the chances my cylinder head is good? Btw I have it marked on the graphs where I think it let go. Throttle position was 50 percent this whole log

Here’s my rod lol
Frame it
On mine, I believe the headgasket let go and coolant mixed with the oil. The head was warped bad and toast. Make sure no coolant was in your oil.

My oil was full of coolant as well I took the plug off and it was straight coolant. I did shut the engine off within seconds of it happening tho
It looks like you were easing up on the throttle at the time of event, which may explain the increase in igniting timing as it goes into deceleration. However, it seems like the ignition timing at the time of the event, and leading up to it is higher than I would be comfortable with.
Do you have a screenshot of your ignition table?

Hmm. The base ignition table looks fine, and the AFRs in your log seem to be good prior to the event.

Anything else I could send that might help determine what happened?

is it possible she had a fairly major HG failure under load and hydrolocked a cylinder which caused the rod to fail?
I can't see anything particularly alarming on the datalog

I really don’t think so. It had arp head studs, a cometic head gasket, and a brand new cylinder head form Toyota. I guess anything is possible but I didn’t even really do a pull it was like half throttle. Iv beat this thing with 15 psi to redline a lot with no issues. Anything is possible I will start disassembling tomorrow, got a block and crank off a guy for 500 bucks a couple hours ago. Leaning toward hbeam rods and 4032 pistons.
