Outer Limits 4x4 Board

Hey all,

don't post very often anymore, but wanted to share some info which might help someone seeing as there isn't much around about the 2.8.

Just replaced the timing chain on the Paj (big job, sump and diff dropped to help access!)
It was original and with 350k km on the clock so really needed it. I had been listening to the rattle get louder for a little while and pulled off the rocker cover to confirm this was the cause and found that the tensioner guide wasn't doing much anymore.
it was that stretched that the valve timing was quite retarded. Since replacing it the following is noticeable.

torque much better low down (doesn't complain pulling from 1500rpm)

much less smoke on high load with low revs

cold starting vastly improved (used to cycle the plugs 2 or 3 times, now can hit the starter as soon as the light goes out!)

much better economy (1.5 > 2L /100km improvement) that would also be partly due to driving style now that i can rev it 500rpm lower in each gear without it complaining/smoking (that's 50/50 city and F3 freeway)

That's about it she's good for another cpl of hundred thou!

Rob.

Thanks Rob - it's in the FAQ.

Thanks for the info Rob,very interesting,
like you said there's not a real lot of info on the 2.8,
on a side issue, how are you finding the MTR's for wear
and tear ? Was thinking of getting them next.

Hmmm,

good question, i have had to replace a few of them because of carcass damage from sharp rocks (get in between the tread blocks). but I'm not saying they're necessarily weak, i just think my truck is a little overladen so i can't drop the pressures as much as i really need to

I suppose i get about 60k KM out of a set going by the wear of each one. I do like them a lot. good in the wet for a Mud compared to others I've had. but might be looking for ATs next to reduce noise and punctures.

but generally, what you lose in mileage you gain in grip, so depends on what way you want to go. And apart from a few punctures in mine very happy at the way the don't get badly damaged by certain types of roads.

Thanks for the tyre info Rob,much appreciated.
