So, rockers replaced and done, car ran really well for 3000 miles and then my wife complained it the oil light was on... Sure enough, the oil was low but there was no sign of burnt oil or smoke. Did an oil change and it did another 3k before burning throught that lot. Decided to blame the DPF filter and changed that. Car was fine for another 3k, and this time less oil was used, although it more than I felt comfortable with. A mate took a shine to it, and my wife upgraded to a V50 D5. Anyway, mate had it for six months, DPF blocked again, oil low again... Changed oil, cleaned out DPF fine for a few weeks, and then it all came to a sad end and threw a rod out the side of the case. We put a low mileage D5 XC90 engine in, including using the turbo from the XC90 and it's been perfect since...
I think the turbo was burning oil, but because of the DPF and low ash oil, it
wasn't noticeable? Not come across another car like this since������

The Volvo book probably says do a compression check before doing any major top end jobs. If the turbo oil seals fail, the exhaust will smoke when a big right boot is used and some engines will leak oil.

Drilling holes in a DPF as some have mentioned is an MOT failure point and oddly enough, tampering with required emissions equipment is a breach of criminal rather than civil law. It can also partly invalidate the insurance policy, as it's an unapproved modification for no track only use cars.
