Hi all, I've bought a v70 t5, really happy with with the size the look, and general performance, however it sounds like a diesel, and is really loud, the other day a list of message come up, alarm system, brake system, and no oil pressure pull over safely, which I put down to possible electrical problems all have now turned off thank god, but it sounds just like a diesel, my local mechanic has had it up on a ramp and has noticed a slight oil leak from the back of the rocker cover? But the noise as an educated guess he thinks might be the variable belt timer?????its coming from area?? Has anyone else had this issue, if so any ideas! I don't mind the sound, I'm just worried it will do some real damage?

Thankyou in advance.
