rod stretching carnage.
So, 2 days ago, my motor got over-revved. I am now following the tow truck. A rod exited the block. I was headed down a hill, I came into boost in 4th and around 10psi and 4000rpm, the motor studdered and died. The road and car behind me were covered in oil. There was no detonation. I will post up pictures later. I'm on my blackberry and I've been up all night.

ouch. that sucks. Time for a build?

I assume those are stock rods... just in time for the $299 special.
Do you have a dyno graph... or just tell us how much torque the 2860 is making for you. |

Did the motor actually spit the big end of the rod completely out of the block? Don't see that one to often.
|
:/
Any estimate as to how high you overreved? |
This kind of thread kinda bothers me in a way. I've accidentally made the 2 -> 1 shift on two occasions. Wasn't logging either time so I don't know exactly how high I went, but it sounded interesting. And yet I still haven't expelled any rods through the side of the block. I can infer from this that either it was a really good day in the Osaka factory when my stock rods (and rod bolts) were made 18 years ago, or I'm a pussy and don't push my engine hard enough.

That sucks, Wes. I have a complete 99 long block (minus throttle body/ iacv) in New Albany if you are interested.

Well, i let someone else drive the car.:vash: but it was an all out 1-2-1 so whatever going from 7krpm in second to first is. Maybe someone with a gearing chart for the 6 speed with 4:10's can tell us.
1st = 15.416 2nd = 9.3029 So assuming he dropped the clutch back in first at 7K and no lose of speed occurred during the "perfect" shift 15.416/9.3029 = 1.657 overdrive * 7000 = 11599 RPM |

So, the rod bolt is mostly in tact. Does that seem strange to anyone else?
|
maybe thats the fail point maybe it backed out and your rod and piston floated freely untill the crank came around and well the ignition..... idk just a thought, well time for the build, sorry about the loss there
|
Wow! Sorry to see that! Good luck in the ensuing project!
|
Isn't it such a great sound hearing your rod go through the block and pan?
In for many pictures when you get it out. |
