i have done a compression test and it was 230 for each cylinder. The car has done 158,000 miles but i do not know if another engine has been fitted. Do you think it is too high or is it ok? The engine runs ok. Any help please

Then the figures are rather healthy, and not a reason for concern - assuming you mean 230 psi, and not some other measure of pressure?

What led you to consider doing a compression test?

...as a cab for 3 years...

Cabs don't do as high a milege as some people think, but it does tend to be nearly all in traffic.

As well as what's been done already, I'd have thought this car was a good candidate for several fill-ups with high detergent fuel, and some motorway or dual carriageway miles.

Shell V-Power and BP Super unleaded got a good write-up in this recent thread:

move from 5/30 at your peril, I would stick to the Ford advice. The heads needs the correct oli. You may be lucky though.
