Thanks a lot for your advice this is the list of parts I was told to replace...

MA111 997 01 86 Seal
MA111 051 01 77 Magnet
MA271 150 27 33 Starter line
MA002 140 55 60 Valve
MA002 140 68 60 Valve
MA002 540 14 97 Valve
MA015 997 23 48 Seal Ring
MA111 094 02 83 Muffler

I changed all of this apart from MA002 140 68 60 as the valve before this appeared to have no oil in it, so I assumed this would be ok.

The muffler that they said was at fault for leaking the oil appeared to have no faults with it when I took it off apart from excess oil, they said something about a crack or split, I saw nothing of the sort unless it was internal?

It also feels like a lumpy running I had on my Mitsi FTO once, which turned out to be the timing belt had slipped a notch, but I assume this would have turned up on thier diagnostics test, injectors were mentioned to me aswell by some one, but again I assume this would appear on their test results...

I'm doubting their competence at the moment, I'll go and order those bits and replace them today, whats your take on their parts and advice?

Cheers

Stewart
