No HAC on landcrusier = Engine damage at altitude?
We are in Delhi and about to drive around Kashmir where passes reach 5475m high. Some last minute research has found my UK 1989 HJ60 Landcruiser does not have a high altitude compensator (HAC) on the 2H injection pump governer.
People have mentioned black smoke blowing at altitude, but not high exhaust gas temperatures (EGT) which i read can apparently damage and even melt the aluminium pistons!
I really want to drive the Manali-Leh highway, but really really don't want to wreck the engine. We are carrying a lot of weight and it is a long route. I dont have a pyrometer to measure EGT either.
- Is it enough to install a new airfilter, gear down and back off the accelerator?
- Should i try to manually adjust the fuel? but based on what, altitude / smoke?
Any information or experiences would be much appreciated,
Cheers, Andrew
P.S. for current Manali>Leh highway status:
