Work continues late last night!
New ims bearing, cover seals, bolts fitted. I went with another NKE bearing from my usual supplier (price had reduced to £6.50). For reference it's a 6204 c3 deep groove bearing and spec'd it with the dust shields but removed both of them. These have an all metal centre cage (I've seen some fibre ones used for this but don't trust them with the heat cycles) and I liberally grease it before install which of course will all wash away after a short time from first start. I don't think I'd trust re-fitting a used bearing not because the old one was goosed but the puller I made uses the centre pin shaft (this one was already uprated) to withdraw the bearing and loads the centre race which will also stress the cage.
Latest 997 version of the rear main seal also shown fitted
Front housing and oil pump installed after a thorough clean, new seals and o rings where required. My FIA water pump was still as new so went back on along with the low temp thermostat although bore score should now be a thing of the past for this modified engine.
All new chains and guides throughout though the old ones weren't particularly worn the plastic does go brittle with age
Cams and intake lifters throughly cleaned and inspected, new INA (which matches the OEM) exhaust lifters
I have the timing tools from last time so all cams re-fitted and both banks timed so the bulk of the work is now done.
Next time ancillaries and then engine can go back into the car (hurrah!!)
