Let's hope the bloodwork comes back clean or at the very least with a solution!
Regarding the engine, I feel your frustration. I myself would desperately want to know why and how this could happen so that I might try and prevent it. Still, I exchange my engine oil every 5k religiously and still my bearings do have some minor signs of wear. It almost makes me want to add a pre-oiler, ie a tank than stores about a litre of oil that is pushed into the system before you start so that there is minimal wear during starting.
Oil pressure lights are a joke. I used to own a Honda diesel (the only engine they ever made, the 2.2ictdi) which ran with 3 litres of oil missing! no light, but the crankshaft died in the mean time.
I have always done my own car maintenance, including rebuilding engines etc. The only thing I can't do is diesel pumps and I have never done an automatic gearbox. Still, I bought my V8 from RPI since I really wanted to have "the perfect" engine. It managed to break in the mean time anyway, in proper land rover fashion :) Should I have done it myself? not sure.
Anyway, keep us posted!
Cheers,
-P
