I had a fair bit of time off over Christmas so I decided to pull the engine out and fix a few oil leaks it had and get the engine looked at by Tony Bellert. He was pretty happy with it all after doing close to 60,000km over the nearly 4years I've been driving it. He replaced the bottom end bearings and I put in a new set of valve springs.
Dropped it off at FPT today for a touch-up tune and it made a health 565rwkw on 22/23psi with the turbo having nothing else to give up top.
The last few months I've had the bonnet painted (finally), rear muffler put on and driving the thing permanently on e85.
