Had a stuffed exhaust valve (on a freshly reconditioned head
) and decided to replace the rattly balance shaft chain while I was at it. Talk about a big job! 
Finished it today (timing kit and VRS kit) and finally got to take it for a thrash - it will now rev to redline. 
As long as I've owned it, it would be vibrating badly by 5000rpm, and I've not had the guts to find the redline. I buggered up the disassembly, and didn't manage to work out if the balance shafts were properly synchronised, but I KNOW they're right now!
So, I'm guessing that some tosser somewhere in the past managed to assemble the balance shafts out of sync, and I'm amazed at the difference it makes. Getting it right is worth the effort!
So, those owners of 2.6 Pajeros - it may be tempting to eliminate the balance shafts in search of extra power, but I'm impressed by how smooth the motor runs when it's right.
Better than my 1700 Saturn ever was (although still not as fast... 
)Cheers,
Scott
