yea so.. i got the "CHECK" light for it... brought it to the dealership, it gave the code for it (POO12), but just like i thought warranty is void cuz of BOV, Filter, and exhaust...(which is bs btw)


anywho, the manager was tellin me that along with the timing chain to be replaced, so will the oil pump chain...

According to ALLDATA, all it says to replace the chain and seals.. no where does it say to replace the chain for the oil pump...

so are they effin with me or what?

The Mitsu svc manual doesn't specifically speak to intervals for changing the oil pump chain but if one is worn enough, IMHO, it just makes snese while you're already in there.

dude that sucks about the warranty

Always go back to stock before bringing it to the dealer. Or you'll pay the price.

and still expect to fight for it :P

how do you go back to stock after you get an exhaust?

dude, without a doubt, ur absolutely right about that... problem is, where this happen, happened 250miles away from where i live... so all my stock parts are back in Long Island...my job requires me to travel to saratoga for 6 weeks... i dont exactly bring my OEM parts where ever i travel ya kno? lol.... of all time and places for this to happen too.. :duh::fail: lol

oh and mitsu corp says bc of the after market stuff..(mind you: Weapon R Dragon FILTER attached to the stock intake, HKS SSQV, and HKS Hi-Power exhaust) increased horsepower...thus elongating it...a filter alone cannont make THAT much power, BOV's dont increase power at all, and the exhaust alone cannot make that much power, that it would put that much strain on the chain..... thats their damn fault for using aluminum for the chain instead of titanium, just to save on weight...
dontcha think its odd that the timing chain elongation has its own CHECK light and section in the manual, with mitsu knowing that it can happen? like the elongation happens soo often, it has its own warning light? lol

Wow, I didn't know there was a code for that, I gotta read the dtc list and see what other wierd codes are on there.

Did you have a tune at all? Have you ever used software top tap into your ECU?

How much mileage do you have on the engine for the timing chain to have stretched? I doubt it is power related, but maybe one of you chain guides loosened. Are you sure the chain is aluminum, it looks like steel to me.

Here is a good video for reference: http://www.youtube.com/watch?v=JX6Z3hSF7hQ&feature=PlayList&p=A31DE62FA98B5CB5&index=14

dude the dealership told me that my BOV allowed me to adjust my boost. They are retarded

negative... just those simple bolt ons..

ive only had the car for a year... but ive been doin a lot of highway driving, between NY, NJ, & PA... but as of now it only has 25K miles on it...i could b wrong bout the chain being aluminum, but either way, the evo should have something a little bit stronger than what it comes stock with...
awesome find on the video!:clap:

:fail: lol...

lol and I quote "The ECM will set a DTC before the chain contacts the oil jet. This DTC is a P0012 VBT over retarded"

:tumbleweed:

Just for reference there isn't a snowball's chance in hell the timing chain is aluminum.

Interesting stuff,
There is mention in the FSM (could be in that video as well) of a procedure where the tech is supposed to read the current strech value from the ecu and then enter that value into the new or reflashed ecu. I think this was in regard to replacing the ecu or maybee even re programing the ecu.

I think those of us that are always reflashing may have to figure out a manual way to check chain stretch cause the ecu's stretch check may get reset everytime the ecu is flashed.

There is brief mention in the video about using the MUT-III to reset the learned chain stretch value when the timing chain is replaced with a fresh one. It also mentions saving the current learned chain stretch value into the MUT-III tool in the event that you are just replacing the ECU (and not the timing chain) so that the value gets written onto the new ECU.

I would guess that the ECU compares the expected cam timing with the crank and cam position sensors inputs to determine chain stretch value since the code triggered is "VVT over-retarded".

It would definitely be interesting to know if this value resets every time the ECU is flashed. I bet it depends on the program you use. Right now it's probably not a big issue because none of our cars probably have high enough mileage to stretch timing chains. In fact that's what makes this case odd. It doesn't seem like anyone should be having timing chain issues at 25k miles. Timing chains are typically more durable and have longer service intervals compared to timing belts.

They only allow a 1% stretch B4 SES lamp comes on. Sucks. Hopefully aftermarket will come out with a super-ultra-stage-nine indestructible chain. I've seen lots of Evo's with lots of power with little mention of chain issues. I'm gonna say to keep that oil changed on-time!!

I'm not sure that value is overwritten when the ECU is flashed.

From what I've been seeing, nothing gets reset when you flash the ECU. Even the LTFTs are still in place after flashing.

Yup, bang on with what I recall seeing / reading.

Agree. As others have mentioned it may depend on what tool is used. It would be nice if someone with access to the proper mutt tool could check it out and see.

Mitsu will cover it all under warranty. There is no mention in the Service Interval list about changing or checking the cam chain - and the chart goes to 60,000 miles:

So as long as you can document that you've performed the stated maintenance items, especially oil changes, you're good to go.

BTW - Mitsu lists that service at 4.0 Hours of labor (R&R the cam chain on 2008 Lancer).

have you had anything done in the dealer like the timing chain cover seal or something else in the area fixed. I wonder if the chain is really stretched or a bad sensor or installed wrong.
