It runs okay, minus the issue I've had for a long time where building boost under load, e.g up a hill in 4th sometimes 3rd, results in terrible turbo stalling and flutter, which is the issue the garage were investigating yesterday.
Full health check and the only issue they found was rusty plugs which I knew about and were not causing any running issues. Made no difference when they changed them, I did tell them it wouldn't. The other issue was the leakage/low compression.
I had wondered if they did the test on a cold engine, does that have much of an impact to the figures? It was sat for about an hour or more before they took it into the workshop and then probably another hours work before they did the compression test, no idea if they warmed it up at all in this time.
I was shocked when they told me the figured because as mentioned above it's a new(ish) bottom end from vaux, I have the paper work. If its just general wear I would be surprised to pick up that amount of wear in only 20k miles since the bottom end was fitted. I have no idea of how the engine was run in other than the previous owner telling me he'd run it in for 5k before it went to Courtney for the stage4 mods. I would imagine it would have been run in properly as he would have been advised by back on track I would have thought.
I will test the compression myself at some point to see if I get the same figures with engine fully warmed, not had a chance yet to do it.
