Well, I replaced all the coils, updated to the new oil pressure relief valve cylinder and spring, and changed the oil... and in the process I found lots of green rubber bits stuck in the oil filter, exactly as described in this thread:
Green chunky bits in oil Filter - Pelican Parts Forums
That, in combination with the occasional P1341 and the awful-sounding ticking off throttle when hot below 2600rpm (not mentioned in the thread above - if this wasn't happening I would keep driving the car), which seems like internal bits of the engine contacting themselves - seems a bad idea to continue driving the car, and I'm probably in for taking the motor out and replacing tensioners and Variocam actuator on at least one side. If I fix this, I'll update this thread with how it turned out.
