OK Its high time to sort through the crap about stockish blown engines as it pertains to various model years (MY) of the EVO. What we need is everyone to weigh in if you've had a failure. What we need is MY, mods, miles, conditions(over boost, over rev, ect.), Pics for knowledge, race/trackday history, and any other conditions you feel contributed to the failure (such as an over rev 2 months earlier, a crap tune, ect). Looks like from the board that some MYs are bearing prone ect. If you know someone that isnt on the boards or have gotten rid of their EVO have them post. Those without Engine failures need not add comments or tuner wars. So:

Model year:
Mods:
Miles:
Conditions:
Pics:
Race/Track History:
Contributing Factors:

I will keep an updated and running list (for better or worse at least we will know variences). PLEASE DONT BE AFRAID THAT YOU WILL "HURT" YOU TUNER!!! You wont this is about the cars themselves and the betterment of the community. No listing of built engines STOCK BOTTOM ENDS ONLY. Also hardcore racers (roadrace only) and shop cars arent needed unless you fell it is relevant. Occasional track guys welcome.

MY03

1)nrcooled
Model year: '03
Mods: Intake, MBC @ 20.5psi, exhaust, DP, stock cat, walbro, dynoflash
Miles: 34k
Conditions: Ticking started about 300miles before rod knock (attributed to lifters)
Pics: none
Race/Track History: 4 roadcourse weekends
Contributing Factors: no detonation signs on the pistons but possibly too light of an oil at the track and too many revs. Shifter at 7600 at the track. No over-revs that I know of. Hit the raised rev limiter a few times @ 7800. Oil was changed after every trackday and everymonth when not being tracked.
Results were a spun bearing on #1 cylinder. Crank could have been machined and put back in but I decided to just do a stroker while everything was out.

Mods:to long to list stock turbo
Miles:52k +
Conditions: not doing to good
Pics:not yet

3)blakevo
Model year: 03
Mods: stock
Miles:15,000
Conditions: it was mint
Hole in radiator pissing antifreeze/overheated threw a rod through my bottom end, complete new engine dropped in. Mitsu said no due to over reving(driving the car hard).hahah

4)Smogrunner
Model year: '03
Mods: Exhaust, cams, cam gears, tme 6.5 turbo, manual boost controller, xede/xflash, ams ic with licp, ngk copper plugs (note: not tuned by Vishnu for these mods). Full explanation to come...
Miles: 35,000
Conditions: cool night at the dragstrip
Pics: coming
Race/Track History: coming
Contributing Factors: overconfidence that my motor wouldn't break. Spark plug ceramic around the electrode broke off and cracked #3 piston. No signs of heat or detonation anywhere. Crank and rods in perfect condition. Probably happened because I had installed a boost controller the night before and turned it up at the track a little beyond what the car was tested for. Also, I wasn't using the ideal NGKbr8 plug. I'll post up more later. Late for work now.

5)Ericr
Model: 03
mods: included a new AMS 3071R turbo kit, 3" turbo-back with cat, 264/272 cams, 680 injectors, xede v3 and SMART
Miles: The car had 7k miles when it happened. Pics:https://www.evolutionm.net/forums/sh...t=engine+blown
Conditions:Shiv was just finishing a 97 octane map and was pulling about 370whp. He then did one more run when the rod blew at about 4k rpm. Shiv's opinion was that there must of been a manufacturing flaw with this particular motor

6)Thomblazeevo8
Model:03
Mods: Stock
Miles: 15,800

Conditions: Driving normal, bam: rod knock, hooray!
Pics: If I can find them sometime, I'll get them up...
Race/Track History: 0
Contributing Factors: 50% chance Oil loss (why, well... no one knows or will tell us, sure wasn't our fault though... A few techs at the dealer said that there's no way a brand new engine should burn through all its oil that fast, and unless I'm mistaken there were no oil leaks)... 50% chance something else, maybe I pushed the self-destruct button on accident

Conditions: spun rod bearing
Pics: eh
Race/Track History: about 25 trackdays and 200 or so strip launches
Contributing Factors: 25 trackdays + 200 strip launches + idoit driver (It was like the Monte Carlo rally everytime I drove that thing) + Eh? = dead evo
It really was just unburnt fuel mixing with the oil that caused the the spun bearing, a little too rich I guess

2) Aikido

Model: 05
Mods: none
Miles: 3400 miles
Conditions: had on my 05 evo VIII, to my dismay my number 1 piston rod broke, and the bearing spun. In all honesty I don't take my car to the track, I don't race it on the street. Mitsu Warranty

Contributing: We think that the car just simply leaned out tooooo much and caused the rod to break

wow, this car must be indestructable! when I get mine I am going to hammer it out of the driveway, punch through as many gears as I can on my way and powerslide into the parking lot where I work! yeah! (yes this is a hidden bump)

come on guys, we know your out there... unless they all changed cars after the failure :gasp:

A lot of people blow their engines but wont come out and say so. So its best you close this thread. People like to keep something like this personal

I think its more Driver error than car reliability. You mod you risk it.

Very understandable, but it would be nice if someone tracked and referenced all the reasons that cause the Evo to go KABOOM! It be very nice for people to know what to do and what not to do to keep these motors running. Especially newbies like me. I know it does sound sort of selfish to ask since any info given is that persons misfortune, but it would be for the good of all Evo kind.

Can someone explain how this ticking sounds/consistency/location please. I think mine might be doing it. (mods are TBE, KN dropin/dynoflash) PM me if you feel it is appropriate as it is off topic.

nrcooled

it was a light ticking that comes from the back of the engine bay. I don't know if it was too faint to hear at other times but it was audible at about 2300-3000k and would "go away". I thought it was a bad lifter waiting for more oil to pump it up. I was wrong. I could not duplicate the sound without load on the car.
