1.6 TDi CAYC engine oil pressure

[sotonsmut]

Hi Guys
1.6TDi having oil pressure issues, oil light stays off on idle. But comes on when revved up. and is very noisy as well when revving up. Oil is spitting out from filler cap so is circulating. Engines done 35k

Any ideas!!

Have you checked the oil level is correct?

Yes just had oil/filter changed, and oil pump and pressure switch checked as well. ?
