A mate of mine came around 3 months ago and asked if he could change his Pajeros engine in one of my sheds, You know what they say " a friend in need is a pain" Well, it turned out his donor engine was more knackered than the one already in there so 3 months one strip down and rebuild later and its finally going back together - it came to putting the water pump back on and the o ring that came in the gasket set was way to big. I had the obligatory moan and got a replacement but that's too big as well, Not quite as big as the first one but at least 1.5 - 2cm too long. Anyone got any suggestions as this is P*****g me off. I want the thing gone.
