i have a 1982 280zx non turbo that up untill about a day or so ago has run perfectly. it still runs great but i have a funny sound from the engine that sounds like 2 pieces of metal rubbing together. i asked a friend and he said it was the timing but i neved heard the timing do this. i check all the oil and belts etc. and nothing there and i just stuck my head in the engie well (lots o room) and it sounded like it was comming from the engine block. it runs the same but this noise is loud and is pissing me off. any tips or comments would help alot. i dont want to do anything drastic to the engine.

thanks

Get one of those mechanics' stethoscopes and start poking around with it ( being careful not to get it caught in the belts, ho ho ho. )

It's probably the water pump.

It sounds like the Water Pump - Disconnect the belt to the pump and see if it goes away.

Also, check the tensioners for the belts. I have an '81zx n/a which makes quite a racket. I believe the bearing in the top tensioner is going. You can try tighteing them as I have done wich usually takes care of it for a little while.

It would be the bearing on the water pump. It would make a **** of a noise, progressively ( and perhaps very quickly ) worsening, until such time as the pump starts to come apart and sends shrapnel thru your radiator etc., thus causing your car to overheat. ;^)
