They are not very good photos since they are only showing you a small section of each cylinder but I don't see any scoring in what you have posted. The squiggly line in cylinder 2 is not a crack but rather just a normal mark in the casting.

PPI was today.

Has these codes: ~Alarm System codes: ~60 Central locking limit position lock not reached. ~54 Radio receiver faulty. ~33 Passenger compartment monitoring sensor.
Has a leak they suspect is from the rear main seal. Nothing else significant of note. Obviously an RMS is a big job, relatively speaking, and was done 4 years ago.

I wouldn't worry much about the RMS. It's not a catastrophic part that you gotta replace. Quite frankly, it will probably leak less if the car is driven more frequently. The pictures you posted of the bores look good. Besides the codes you posted, what about the rest of the PPI? Suspension, exhaust, powersteering, cooling? What needs to be replaced?

Let me guess, it has an aftermarket radio installed?

BINGO!!!

The alarm has an open circuit at the radio level. This is because of the alarm wire that was clipped to the Becker radios. If dismounted, it will trigger the alarm and give DTCs. One you find the alarm wire, cut the connector off and insulate the wire. The car will be happy again.
