Just finished playing with the car. I was wide awake at 6am so i thought fook it get in the garage. I took the tensioner off. The stud and nut look fine. I put the tensioner back on and its defo tight now. I torqued it up too.

I wonder if i had a bit of cossie paranoia lol.

Im still waiting for a dizzy cap/arm to arrive then i will get the rest of the engine built up.
