Motor failure on the dyno today
I have a spare head in my basement, and I'm 99.9% sure that my head is still good. So no way I'm spending 2800 on a new motor. I'm hoping to get this fixed for a few hundred by either replacing the piston and rings or buying a new (used) shortblock. If I was shelling out 2800, it would be on a fully built bottom, and I would slap the stock head back on. but thanks for the suggestion!

sorry to hear about your loss. I see you have an '02. Did you change the oil banjo bolts? Can you get the EMS maps from your tuner? Did he check the plugs inbetween runs? When you looked inside the cylinder, did you see scores on the walls? At idle was the motor shooting smoke out the breather hose?
Evan, You are more then welcome to post screen shots of the timing and fuel map within the ecu. I wont have hard feelings. I dont lock my tunes like other tuners.
You were there with me and saw the plugs how they came out from the 2 previous pulls and like I said the only change after all was looked over was vtec. You also saw the plugs that I pulled out of the engine before I even started tuning and the way those looked. I took every precaution I possibly could have to prevent any type of damage happening. I even said to you on numerous occasions after we started hearing the noise that I was nervous that I really dont like to see things get hurt when I am involved.

It will be interesting to see what actually failed. Very cool of the tuner to come on and suggest you post the maps up for everyone to see. Sounds like a guy that stands behind his tune to put it on the spot like that two thumbs up.

Or a non resistor plug. Unless you have wiring issues you do not need a plug with a resistor. I have more electronics on my car than anyone on this forum with the exception MAYBE of tony from T1 who I doubt runs resistor plugs in his car. I also run non resistor plugs in my DD S2000 and have no issues with either car.
Technically that's not true anyway the plugs out of a rotary (surface discharge) are resistor and would work in our application.

Can't believe I'm the first one in this post to say this... Miller doesn't exactly have the best reputation for a tuner or engine builder. There are quite a few horror stories floating around about his work, including the time he installed a set of k-series pistons backwards for a customer.
Do a quick google for NRG Tech and you'll see I'm not just some trash-talking troll. I typically keep my thoughts to myself, but in this case it seems you didn't know...

Well I opened the motor....
EVERY single piston is melted on the intake side, exhaust side is fine. And the cylinder wall on the 4th cylinder is toast, there is a crater melted out of the top part of the wall. I took some detailed pics to post, but I'm on the way to work in a sec (need $$ to get a new motor now ughh), don't have time now. I will post them up later tonight.
