Time for an update .....
The GTI has been off the road since March. I was coming home from work one day when the engine started to make a worrying noise and the engine management lights came on. I pulled in immediately and got it towed home. Had a mate run a diagnostics on it which i sent off to George Dalton, and the possible causes were not good. I was in the middle of changing jobs, and didn't need the car on the road so put it on the long finger.
So at the end of May i got the car up to George Dalton. He diagnosed that the intake camshaft had broken between cylinder 4 and the end of the cylinder head and damaged the head. A replacement head was needed which i managed to get off paulmk5gti (Thanks Paul
). Got it delivered to Ireland thanks to deliver-it.ie. George removed the valves on the new head and cleaned them along with the intake ports. The valves were then reseated and the valve stem seals were replaced. As well as this, the engine got a full service including new oil, air & fuel filters, oil pick-up pipe, spark plugs, timing chain, coolant, head gasket set and new cam follower.
Just picked it up last week and its running better than it ever was! The service and communication from George was top notch and i would highly recommend him. He has no idea exactly how the damage happened, has never seen it before. He reckons it was a faulty camshaft from factory.
