I had another day down the garage on the weekend. Managed to get quite a lot done in fairness.
I re-fitted the head and it started first time... With no leaks

but the bonnet won't close now and it has a puncture
I think I've sussed the poor idle too, I blanked off the vacuum hoses that come from the inlet manifold directly below the throttle body (The ones that usually go to the oil breather). Apparently these are needed for the idle??!!
Jobs to do:
Fit Turbo Cooler
Sort Bonnet Latch
Sort Puncture
Re-fit oil breather
MOT
Clean and hoover
Drive
Here are a few more recent pics:
Cheers!
