as above finally got round to putting my s1 turbo engine back into car after it's rebuild now all i need to know is what viscosity gearbox oil should i be using and how much.
thanks.

 

75w90 semi synthetic.

 

how many litre's aswell mate

 

3.1 liters. Use a syringe or somthing like it to put it in because you will get about 2 liters in there and it will start coming back out. Remember there maybe still a bit of oil in the gearbox so it may not take 3.1 liters but should be close.

 

one of the best tools i bought
