Engine type-98+ln2
Component that failed-piston ring lands
Setup used- single fogger wet kit 75 shot on tr6 plugs
Circumstances- no timing pulled via msd dis2 box while doing holeshot
Who made the part-gm

2000 2.4 5 speed z24
cylinder 3 exhuast valve spring broke, lifter jammed in the bored cam lobe wiped out and lifter fell apart into peices, valve went threw top of cyl 3 piston, drove it to work and home like that for over 2 weeks with a dead miss on cylinder 3 and no second gear, LD9s just dont give up!
1985 IROC Z28 5.0 TPI 700rf b&m shift kit 9 bolt 3.73 posi disc brake rear
after i sold it kid over reved the hell out of it, snapped 2 rods, which somehow swung up taking the cam out and sending a 4" long section of it (3 lobes long) threw the side of the oil pan between the motor mount and the starter, along with what looks like 3 bearings and 2 lifters and half of a pushrod. (sooo wish i could been there to see that happen)
on a good not the 5.0 is out trans is redone rear is redone and new motor will be in soon (sitting on a stand, wheathers been nasty)

Erik Packard
Engine type: LN2 2200 SFI
Component that failed: Cam Bearing Failure
Setup used: Standard Used Junkyard engine With 106K on it, 4-2-1 header and full 3 in exhaust with full cold air intake
Circumstances: Normal driving/ Start-up Idle
Who made the part: GM

Erik Packard
Engine type - 98 2200
Component that failed- Crankshaft bearings/ Oil pump, 5 speed synchros worn
Setup used- stock 130,000 mile engine, trans
Circumstances- previous owner riced it out and probably abused it
Who made the part -GM
If an installation error, please admit it. none
What did you replace it with- a Eagle Vision
Engine type - 91 2.2
Component that failed- Alternator 3 of them, 1 Reman, 2 new,
Setup used -stock one died at 71,000 miles, reman like 14 months later, new one a couple years after that
Circumstances- I think a design flaw
Who made the part -GM
If an installation error, please admit it. none
What did you replace it with- a used one from a 3.1 Grand Am
also blew up 3 circle track racecar engines. 2 2.2's and 1 2.3 GA. All 3 threw the rods out of the block. And all 3 were autos dooh
Amateurs
Engine type : L61 Ecotec on all accounts
Component that failed (chronologically): factory piston ring lands (6x), bent factory rods (2x), one chewed factory head and valvetrain, melted Wiseco 8.9:1 piston, destroyed cylinder wall in cylinder #3 which ate yet another Wiseco piston and all the valves in cylinder #3, synchronizers in 2nd (3x) 3rd (2x) & 4th (1x), detonated both spider gears in the stock f23 diff, seized front balance shaft and snapped waterpump chain (exteneded time at 8k + rpm with factory balance shafts), seized all 4 eagle rods (my EF up), scored 1 crank in the process, broken 2 factory upper engine mounts......and I can't remember breaking anything else.
Circumstances: all except the seized rods and scored crank were racing and heat related (high rpm for extended periods), seized rods and crank was a failed attempt at making a block off plug for the balance shaft delete when the factory balance shaft bearing was previously overheated and backed out when I tried to put the plug in - ended up blocking off all oil flow to the rods and crank - cooked the whole bottom end and block in about 30 seconds...shortest rebuild ever
All parts were OEM except where noted above
Pistons were replaced with more factory pistons and then a mix and match set was used when I busted 2 more only went forged when I didn't have any more factory pistons laying around to put in the block, decided to do forged rods at the same time as the last set of pistons gave up the ghost at 17 psi and 2 of the rods had a slight bend to them, replaced bad trans with good OEM trans for the diff and synchros, balance shaft delete kit (home brew as I have a lathe), rksport upper engine mount
Everybody love carnage pics...
Seized balance shaft
Detonated spider gears
One of the many factory pistons

When the diff went out
Funny, she doesn't look like she's evil....but she sure acts like a brat!
2.2 L Ecotec, P&P Head, Stage 3 Comp Cams, Supertech 76 lb Spring kit, Supertech Oversized Valves, Wiseco 8.9:1 CR Pistons, Eagle H-Beam Rods, Home-Built Turbo Kit T3/T4 57 Trim Intercooled, 78 lb/hr Racetronix Hi-Z injectors, Aeromotive FPR, Racetronix f body fuel pump,MEGASQUIRT MS3 + MS3X Finally street tuned on 21 lbs! Now if only I could get it to hook....
Engine type: '02 LN2
Component that failed: Valve Stem
Setup used: Stock bottom end with all bolt ons (Header, intake, rockers, msd ignition, ported head w/ +1mm valves, etc)
Circumstances: Normal Driving (I was leaving a parking space on a beer run of all things)
Who made the part: I forget, they were stainless +1mm valves from a head I bought already assembled/ported.
If an installation error, please admit it: Probably. I bought the head with the port/polish work already done and the valves already installed. I was running the motor to 6200RPM or so (6500 rev limit) but I have been running to 7k on my new motor with stock valves and its been fine with much more abuse so far.
What did you replace it with: The motor was replaced with a stock junkyard motor that was later torn apart and built with forged internals and turbocharged.
Pics of the damage (we all love some carnage):

Glad to see you all are keeping this alive.
