A better day today, new AC pump, the old one was absolutely shot, a good 1mm of wobble on the drive pulley.
New on it, a rather simple job, and all gassed up and blowing ice cold without the grinding
Larini H pipe fitted too but its hardly any different but I have not given it the beans yet.
Checked the rear valve, lubed them up and replaces the Circlips that were missing meaning the actuator arm could have just fallen off, but some how it didn't.
Adjusted the NS sill trim as it was wonkey.
Just a mega detail this weekend and she is good to go!
Some interesting points noted while underneath. This is a wet sump and not dry like the 4200. Also the combined oil and water pump is no longer there. Its been replaced with an Aux belt water pump so you actually have 2 aux belts. 1 for the water pump only and another larger one for all the other gubbins.
Didn't see the oil pump but assume thats inside somewhere.
