So here's the thing, bought a scooby 3 weeks ago... put new water & oil on it , drove great never lost any water & oil, used to work and sometimes some pulls but nothing more. (always warmed up etc)

Did the cambelt , tensioner etc etc,

And know after like 500 miles driving, checked the oil, beneath L , and had lost a lot of water /:

Edit:

drove 3th and 4th gear on full boost and checked expansion box , water acted normal

Drove from 4k rpm till redline with a mate behind me, doesnt smoke at all...

Cheers!
