Had the sump off today and I dont think it was too bad:
Not bad considering it has been on longlife servicing for the first 92k of its life. I obviously cleaned the sump and changed the pickup pipe, which also wasnt blocked at all. If I could tell without taking off the sump, I wouldnt of bothered at all. On the plus side it is not sporting some fuch's Pro S 10w40 and no longer has broken dipstick tube floating around the sump.
I was kind of hoping it would be blocked and would of cleared the crappy sounded startup, but no luck there.
