Looked at the tensioner more precisely and found what was causing my problems.
Then I put the tensioner back in and pushed the upper side down so the springs released.
The car is back together
runs nice - 5k rpm+ is now alfa and omega of this engine (Y)
But the chain is quite loud now. It was a bit loud before but now you can hear it if you stand outside the car :wasntme:but doesn't bother me hehe
Got to get the 2 bolt for the exhaust cause it's not a tight fit now....
Did a 3-4km run only....tommorow I have to put the front of the car back together and do some other things - think the ignition/timing needs some tweaking 
So...so far so good - hope that's that!
Thx again frank (Y)
