All four pistons are slapping around, you can move them side to side with your hands; piston 3 being in the worst shape.
It is not overbored already though, and the pistons are original (still have the markings). There are some funny scars on the top of the piston too. The bore was mildly scored, but nothing bad.
So, I began to wonder if the 90,000 miles on the clock is actually all it has done. I ran my chassis, eng and g/box numbers through Calvin, but they did not seem to provide any definitive information; saying my engine is domestic and gearbox was LHD export. The engine number did not match what a 2/2a manual said for the chassis number, or anything else in the manual for that matter.
Here are the numbers:
Chassis: 243 213 66H (11/71)
engine: 241 548 80A
gearbox: 255 059 36F
The workshop manual was printed in the mid 60's, so maybe i am thinking maybe the numbers got changed around for the later 2a's like mine, and therefore it is the orig engine? Throwing it out there for anyone who may be able to enlighten me.
Also, is the kind of wear i have explained expected for a 2.25 petrol with about 90,000 miles ?
So the head and block is off to get some attention, and will get a .40 oversize and fresh pistons etc. Hopefully will be all good and done within a fortnight; can't wait.
That amount of wear is quite possible in 90,000 miles, particularly if it has not been properly serviced, or has done a lot of short trips or a lot of e.g. farm work with not only short trips but a lot of low range work. Engines and oils from the 1950-60-70s were not as durable as engines and oils today, and although this is a very durable engine, when that engine was introduced in 1958, few engines were expected to do 100,000miles before overhaul.
On the other hand, with an odometer that only goes to 99,999 miles, it is quite possible that it has done 190,000 or even 290,000 miles!
