thanks matt, i do know reworx, mapped my 200sx a while ago... they are a bit far to drive the car as it stands at the moment, but will bear in mind. really coudl do with some local second opinions, gut tells me its water pump, but before i rip it out i wanna get it looked at.
thing is car was perfect, no noises etc before the aux belt snapped due to wear and tear and the tensioner failing. that wrapped itself round the PS pump, bending the axle which i have replaced with a refurbed PS pump, but still got a very odd noise under load from 1-3k, soemthing unhappy under strain... so alternator, water pump and or main crank pulley are all thats left... had a thought it maybe the chain, but took out the tensioner that was ok i think, and the chain does have a small amount of play, can move it up and down between the pulleys, but cant see how its linked to the aux belt snapping...
any other thoughts and help much appreciated guys n girls... cars off the road, just in time for me 30th lol
Paul
