I just finished my Phil Waterman style engine stand this morning (Thanks for posting the design mate) and put it to the test straight away.
My son who happened to be home from school today woke up before Midday (I was stunned!) and decided it was a good time to start playing with my Truck.. (Its mine son, mine!)
So we cleaned the crud off the gearbox and then tried to take it off, Boy was it on tight... so we kept going back to cleaning the engine. I rang Euan for some advice (Did I remember to say thanks?) Since we were positive it was the gearbox that was stopping the pistons moving we started pulling the gearbox apart where it was...
Yuck was it a mess, it appears condensation or something had over a period of time filled the gearbox with water.. It was a great excuse to set up the molasses bin and after buying a 3/4 ring spanner and an extra half hour of toil the whole lot went for a swim in molasses.
The best part is, the pistons and bearings appear to be in great shape. The head needs a lot of work, but appears to be fine as well.
My son and I had so much fun we decided we should complete the engine rebuild ourselves.
Thanks Euan and Phil for all your help.
