[QUOTE=MGJohn;2779549] I have been informed by someone when they worked for the Chinese operation at Longbridge, that the Chinese use a FORCED not GRAVITY fed casting process for those major engine components, the Cylinder Block and Cylinder Head. QUOTE]

I thought the Longbridge casting were vacuum cast not gravity !

I do not know how the Longbridge/Powertrain engine components were cast. Rightly or wrongly, I believe pressure casting provides a denser end product. When handling the MG6 engine, I got the impression the major alloy components were harder material than Longbridge K-Series I've handled.

Back on track. I got all set-up to start work on this car when my wife told me the remote lever release for the Hatch on the ZS no longer works. So before touching the ZT-T, decided to have a quick look at that for her. Quick look... fat chance. Three hours later, result. I had to loosen all eight main hatch top hinge bolts and nuts to slightly re-position the Hatch Door. Then after close alignment checks and a slight modification to the cable release Tang, normal service restored.

The Sun was well on its way down towards the Hills when I finished the ZS Hatch task so packed tools away and closed bonnet on ZT-T ... Sudden temperature drop then soon had my feet and hands feeling the cold. Cold stopped play. When opening up that ZT-T bonnet first thing, again moisture condensation on most of the still very cold metal parts. I had covered the exposed top of the engine with close fitting soft rubber mats last night. This seems to have kept the condensation away from the exposed engine Camshaft area.

So another day passes without progress on the ZT-T. Could have done without that MG ZS Hatch distraction.

During the near continuous bright Winter Sunshine, directly overhead I heard the distinctive call of the UK's largest Crow. The Raven. Looking up the distinctive profile of its wings and tail along with that call confirmed identification. Not that rare to see over my house and garden area. Every time I see one they are always flying South to North towards the City Centre. Maybe they use Gloucester's tallest building, the Cathedral as a sight marker.

Ravens always seem to fly rather higher than other crows in my area. Less than five minutes later, another Raven with a slightly different call overhead ~ sounded like it had a sore throat ... ... again at the same height and in the same South North direction towards the City.

Helps to pass the time...
