Recently purchased my first 4WD, a '91 NH Pajero GLX V6. Other than she has the turning circle of the QE2, and uses about as much fuel, I'm fairly happy with my new toy (when I can get my wife out of it)! But a scary conversation with an owner of an older V6 Pajero who spent something in the order of $2500 on heads and was told "there's nothing you can do to stop it happening" and "it happens quite often, they all do it", left me feeling somewhat concerned. I can only assume that 'it' is corrosion of the alloy heads. Is it a common problem? Does anynoe else have similar horror stories with these motors or do most not have problems?

Yonnee, been there done that as
well.
As I said, The motor blew a head gasket around the 200k mark, but because my wife drives the PJ far more than me, it wasn't picked up for about 3 months. When I mentioned that to a mechanic mate, he told me about the heads warping, which has been confirmed a number of times. I was quoted $2500 for an engine rebuild, provided the heads were OK. More likely to be around the $5k mark all up. Decided to screw that and put in a low K imported motor for around 3k including new clutch. After that had the Air flow sensor play up, and bought a 2nd handy. (wasn't that, wrong dianosis) Then the Idle sensor and replaced that. Now goes like a beauty. Now have a spare engine as
well for some parts, and the heads can be reused with a bit of work.
