Well little update is in order I suppose.
The cambelt slipped, causing the exhaust valves to hit and crack the pistons. The lad who done the cambelt has accepted responsibility of not doing the bottom pulley up as tight as it should of been. So the car got put on a trailer and taken away to have new head and pistons fitted.
Hoping for the car back before the weekend, hopefully running spot on. The lads with it know what they're doing and fitting my car in between stuff and they are stacked with work so taking a little bit extra time, but its all worth it
