low oil pressure.

Trust you checked the oil level and it has been changed recently. Also correct grade of oil used?

Next check valve clearances.

Yes, Just bought car and changed the oil to Castrol Magnatec with the correct grade. think it was 5w 40. Oil levels are ok. There was an oil leak on the car coming from the sump plug but I replaced this while doing the change. There is a posibility the wrong grade of oil was used in it before I bought it.

Errrrr- they always sound like that Sir. Yes they do, it's usually the timing chain and tensioners. If it doesn't sound too bad off idle I would run it and keep an ear on it, if it gets worse part-ex it for something else.

Worn oil pump,worn engine,blocked oil ways in camshaft (common problem caused by lack of oil changes).It will only get worse it certainly will not get better but surely it made this noise when you bought it .
