Condensation will only go milky around the oil filler cap not through out the whole crank case.

Sounds like a blown head gasket. Have you been loosing coolant lately??
When you say the car has been playing up does this mean a miss when you start it up or hard to start?
This is something that needs attention straight away or you will do more damage to the motor.

I brought the engine and am picking it up this weekend.
I have had no probs....

It can cause problems....
The play in the gearbox is also something i would get checked as movement here can cause bad vibration. Id get the gearbox movement fixed first befor worrying about the tailshaft as Id be guessing thats the cause of your issues.

My advice...
Your running to rich in you mixture and your timing may be out causing incorrect burning of the fuel/air mixture leaving carbon deposits in the chamber.

My advise would be to give her a good tune up once over and as stated above it will reward you in many ways.

Bad uni joints will have play in them if you hold the tail shaft and the joint out of the grea box / diff and try twist them in opposite directions there should be very little movement. If there is lots the joints are loose and worn out.

When you removed the tail shaft did you mark it to the diff and bolt it up in the same way again as this can cause vibrations if bolted up to a diffrent hole......
Hope it all makes sence good luck
