The two are unrelated. You can make great oil pressure and have ruined bores, there shouldn't be any oil there, it won't affect pressure readings.

These guys - Archer Motorsport - are local to you, just came highly regarded in this review;

Might be worth a visit for an opinion at least?

Either way, make sure whoever does the borescope knows what they are talking about... there is a difference between normal bore marking and actual scoring.

I have not had a chance to get the bores checked yet, and been careful about warming up and oil levels.

But today the 'check engine' light came on just after I set off this morning.
I have read that there are many reasons for this warning light, and it often sorts itself out. But I wondered if there was a chance it was due to a problem related to my black exhaust/burning oil concerns?

Looking around the web I did find an 'iCarsoft Multi System Diagnostic Tool' recommended by Porsche owners for getting feedback on warning lights and resetting them. Wondered what people thought?

Just seen your location.. RPM are 10 minutes away from you and can do the borescore, about £100/£150 if I remember rightly.

Its a basic tester that will do the job .. you need the fault codes in the dme .. then post them .

For a score issue then fouled plugs causeing a misfire but there are several other things that can cause an eml or indeed a misfire with cracked coils being the most common .

Basically we need a fault code to go further im afraid .

Turn the ignition on but dont start the car .. is the oil pressure reading at 0 or higher ? .. it should read zero .. if not you have a faulty oil pressure sender.

Bore score has no efect on oil pressure .

Is the car running ok or does it sound lumpy ?

It might be lambda sensor ageing which is basically .. they are getting old .
