On start up from cold my engine makes a noise as the oil goes up around it then goes away. Once the oil warms up it gets much noisier , like a metallic sound ,but there has been no drop in performance , the engine still pulls well, could this turn into a terminal problem?, any ideas.

How does the oil pressure light behave ? An oil pressure gauge is THE most important accessory...... It does rather sound like bearing rattle - you could try a set of new big end shells (easily fitted with engine still in the car) - but really - it probably needs an exchange crank and a new oil pump fitted. I assume you are on 20W50 oil - and the oil filter is new(ish) - and the pressure plate and spring are present and correct in the filter canister?

It has fresh 20w50 oil in , a new filter and all the filter parts ,oil light comes on when oil is warmed up , only when idling.

Well - you could drop the sump and have a look at the big ends -and the centre main which will tell the whole story.......

Thanks

just to add it seemsto just make the noise when the engine is reeved hard underload, but doesnt lack power

The more that is done - the more damage is being done..... Drop the sump.......
