Hi Greeting from the sticks - Worcestershire uk. I was wondering if any one could help me? This has been going on for 6 months, I had a new cylinder head fitted on my jeep - came back with poor starting lack of power - took back to garage - could find nothing wrong. Towed with jeep - shuddered badly and then starting pouring black smoke - back to garage - thought it could be EGR Valve. Replaced still had problem - told to take to main dealer... They found cam belt timing out on crank by 1 tooth and exhaust cam out by 2 teeth and cam tensioner was on setup correct so belt had jumped. Said I had had a valve strike on cylinder 3 would need head removing and checking - back to original garage. Stripped head to fin strike on cylinder 3 - head supplier recommended dropping sump to check for internal damage! Garage did not went ahead and refitted head- when started the engine there was rumble from the bottom end... Dropped sump - find big end on cylinder 3 shattered! Could the valve and piston strike have caused this damage as the garage say not? It seems to much of a coincidence to had the strike and the big end go on the same cylinder ?
