The other weekend the wife and I went camping in northern New Mexico and brought both of our Monteros. Met up with a friend who also just picked up a 3rd gen Montero. All the vehicles did quite well, but we certainly found the limits on the main trail leading to Goose Lake.
It was a hot day and with the vehicles fairly well loaded down and with plenty of low speed crawling- temps in the 3rd gen vehicles started becoming problematic. We pressed on several times after the vehicles cooled, but ultimately the trail stopped us at a loose, high camber rock wash out in the trail. Our 3rd gen was unable to make it up this small obstacle as traction was just not there. For whatever reason, it seemed like the center locking differential wasn't really working. Front tires would spin and the rear wasn't doing much. Our red Gen 2.5 made it past this obstacle without any such issue and I was honestly very surprised the gen 3 was unable to pass. If anyone has any ideas on the 3rd gen's center locking differential, I'd appreciate it.
That said, the red Gen 2.5 did extremely well on the trip. It was without question, the stronger crawler and proved to be extremely capable as an expedition vehicle. As this was the maiden trip in the vehicle I was honestly a little hesitant to push the vehicle, but it really surpassed my expectations!
There are a few things that I need to sort out still on the build. Other than an alignment and installing the rear springs/panhard bar, the engine likely needs some maintenance. When the engine is at operating temp, there is an excessive amount of ticking/noise at idle. Seems like hydraulic lifters, or something rattling away, but it becomes more quiet when rpms are above 2,000 or so. When listening to the engine with a stethoscope, it sounds like it's coming from the main crank case as opposed to the valve train. Any thoughts on this?
