Oh that's crap, I have a MY10 lol, I wonder if there is a point at which they changed these? Might be an idea to upgrade now, bit of work involved tho.

[Seffy]

Surprised Mitsu didn't do some kind of recall for it.

Then again who knows if they were aware of it. ;_;

[citris.87]

Lucky I still have warranty, Ill upgrade to another evo before the warranty runs out lol.

[scott_drake]

Wow and I was thinking of getting an older evo x well looks like ill have to rebuild the bottom end if I end up buying an older one

yeh if u dont want any dramas just make sure you buy a LATE 2011 BUILD onwards

What exactly was changed? I didn't saw a pic comparing different rod designs used in the 4B11T.

It sounds like the materials used, they were using something a little weak, or maybe too thin.

We need solid confirmation, not just speculations.

Go look up my faults topics

[SIX]

mitsubishi would have to be aware of this , i mean they would have started to see the 4b11T coming through now ???? with how may they sold ... the question i have to ask , is how hard are these cars being driven ???? what modification have been done to them ???? and if it is just a fault on mitsubishi behalf then why have they not recalled them yet and it would be negligent of them not too, there fore putting them in legal striff if something were to go horribly wrong ????

im not doubting the fact that its a fault of the engine , but i want to know what it the root cause to make the engine do this , what stress is it under and what condition make it do this .... because i pretty sure normal road drive to road and legal conditions would not do this .... not doubting your report at all ... but i this all the facts need to be laid on the table .. if we are going to lay blame on and apparent badly built car

[scott_drake]

Look up, plenty of stock evo with these problems....im getting the old and new jew timing chain tested by a mate of mine who is an engeneer for a mining company to test out the stregnth and write upba report of the old vs new chains then take it to mitshi and get them tobda a recall....mitshi are aware of this problem some accept warranty some claim wear and tear....there is a loop hooe tho ik working on

They might be stock stock doesn't mean they haven't been treated like like shit that what I'm saying

[Craker]

Car manufacturers are like that sometimes. Take vw for eg the problems they have had with the gearboxes. I was talking to a guy today that had a golf with a dsg and was having intermittent faults with his box. He even recorded the problems but vw would not do anything until the box totally stopped working.

This is the exact reason the manfacture have redline limit 7300rpm, boost cut off 30psi, engine after run thermo fans if engine temp to high, thernostats etc.....
