Replying to David (RutlandRover) as I've not been here for 3 days due to driving my car again (Tuesday afternoon drive to Portsmouth with a Brian James transporter trailer on the back, Portsmouth-Caen overnight ferry, drive to La Rochelle, collect a BMW 330d that had almost died while the owner was on holiday a few weeks ago, drive back to Caen, night ferry last night, dropped BMW off at the owners local garage who have quoted considerably less than the €4,000 that the BMW main dealers in La Rochelle had quoted, and back home about 3 hours ago. Turned over 468,000 miles just before getting home too).
Anyway, flex plate isn't new, for some unknown reason, LR put a mark in yellow paint on them so the fact it still has it means it hasn't ever been changed. Spark plugs look to be some dubious make (Beru?) so probably came from the same place as the dodgily named oil filter and need to be changed. Stripped exhaust manifold threads aren't uncommon, usually the rearmost one of the RH bank or front one on the LH bank as these are the ones where it is awkward to get a socket on them square. Threads may well be 3/8 UNC if the heads have been changed and heads originally from a GEMS were fitted (see my reply to your other thread in Oily Bits). Easy test is to see if a 21mm spark plug socket will fit in the hole where the plugs go. If it will, they are GEMS heads but other than the machining identical to Thor heads.
I have repaired stripped manifold threads in the past using cut down Toyota head bolts. They are M10 thread (so a stripped 3/8 UNC thread hole will take an M10 tap perfectly) but have a slimmer bolt which is about spot on to cut an M8 thread on. That way I ended up with a stud that is M10 at one end and M8 at the other. Using a stud makes putting the manifold back on easier too.
