Simon,
The compression figures you have quoted look to be a bit too high.
But that could be down to gauge variation.
One thing I have learned is not to trust one gauge as being the gospell on compression tests.
So long as the reading are near the quoted figures.
The variation in the figures, gives a better indication of engine condition.
F.Y.I
Once the other areas of engine operation, noises and oil pressure are checked and you are satisfied that there is no major engine problems.
A compression test is carried out and the figures examined.
As I said the outright figures and the variation are checked.
The figures quoted here are what I would consider to be on the limit of around a ten percent variation.
Ten percent is the nominal figure that most manufacturers that I have consulted with use within the specification for engine condition.
With this engine I would say to repair it with the idea that it may require attention (rebuilding/replacment) in the future.
And to answer that question.
No I dont know how far in the future.
Engine and vehicle life is determined by its use and service history.
Hope this helps and I didnt sound too much like a smart a**e.
Noel.
