Well the car always has a change ticking sound, a little lit tappets but difffrent, Sparkie mentioned it could be in the inlet gasket. When my engine decided to fire off its oil cap i washed it with degreaser and water, and when i started the engine back up after the ticking sounded even worse, i decided to take the plunge and last night removed the inlet/eghaust manifolds, its missing 3 studs, 1 beign closest near the turbo and it does appear thats its been blowing.
tonight i plan to get it back together with fresh studs and nuts and a fresh gasket, fingers crossed it will be better.
