The cams 'look' exactly the same. Its only if you measure that there is any decernable difference.

try this link, viewtopic.php?f=29&t=4223 look at the photos where I pulled on the mivec pins. Yours could be stuck. If not, try out the mivec solenoid and check for good oil pressure. :D

The disassembled mivec rockers and shafts.

As assembled and how it would be seen looking down on the engine

How does it work?
Oil pressure within the shaft pushes the sping loaded plunger upwards, locking the high lift cam follower to the low lift one.

Potential for fault:
If the plunger becomes contaminated or sticky due to glazing of oil deposits, the plunger won't be able to move and lock the rocker (or may get stuck in high lift mode)
The return spring could fail and leave the plunger in the high lift position.

The oil feeds to the rollers are very fine. There is potential for these to become blocked and so starve the rollers of oil resulting in rapid wear/breakage.

The Tappet adjustment part of the rockers have been known to crack and break.

To Test: (can be done with all parts fitted to engine)
Using a mitsubishi special tool (I've got one) you can pull the plunger up while carefully moving the high lift rocker to ensure overall smoothness and that the plunger moves freely and locks the rocker in place. If the plunger is hard to move, the system will need to dismantled for repair.
