4B11T Evo/Ralliart Faults
Posted: Sun Jun 02, 2013 1:08 pm
hey all just wanted to put down the known faults of the 4b11t motor and evo 10/ralliart common faults please list any if not listed
Fuel Injectors (Leaky Seals)
Fuel return line (known to pop off, cable tie fix)
Fuel Pump Relay (not going into closed loop causing engine to run lean)
Spark Plugs (broken tips, lean or timing chain stretch)
Timing Chain (Stretched chain, weak chain links)
Ildler Pulleys/ Tensioner Pulley (plastic pulleys getting to much heat causing belt to jump off or snap)
Rear Diff Pins (not enough oil supply)
Slave Cylinder (due to being PLASTIC!!!!)
AYC Pump (seize in very very cold temps)
Recaro Seats (stitching coming apart)
Rattle from doors (loose window bolts)
Maf air flow sensor (dying, unknown cause)
Camshaft Cap (breaking, weak design)
Rocket cover (melting, plastic design)
Gearbox 2nd gear grind (synchros not designed right)
Conrods (snapping, bending, stretching, weak metals used)
Brake rotors (warping, harsh pads)
And lets not start on the interior squeeks and rattles, yet alone the paint
Why so many problems with such a new car, seems like mitshi made the car, they put a VERY VERY VERY careful driver behind the wheel who is scared of redline LOL, for the testing, and seems like they did not road test enough and push it to its limits, if they DID push it to its limits and test it longer they would have solved all of these problems well before the car hit the market back in 2008. Seems they just RUSHED into it
Anything else please ADD
