Sorry to trouble you guys but I was wondering if anyone could come up with any suggestions as to what might be wrong with my car.

I had been driving my car fine all day and it was only when i tried to restart it after stopping i realised that there was a problem. The car would start so I called out a recovery company.

They said that the engine had a fault P (something)? which meant that the Cam sensor had gone. I had my vehicle towed to a repair garage who replaced the Cam sesnor but still no luck.

They suggest that I had the head taken off and inspected (2000k+) as it could be a blown head but there are no signs in the oil filer cap?

Any suggestions as to testing what the problem could be?

Thanks guys, Andy
