I'd also recommend Nicholson M, and we had our engine zero timed a few years ago by them. Not the cheapest, but cheapest is NOT always best when it comes to engine rebuilds, but they were fantastic.
We had to have our crank case sent to the USA for machining due to fretting (in which case it might have been better to use Peter's US shop but we didn't know this before the work started), so if we'd continued to run no doubt it would have got worse. We actually rebuilt 100 hrs before TBO as we'd just acquired the aeroplane and wanted to make sure we had a known quantity.
