This engine has had lots of recent work and runs very well with good oil pressure. I suspected the timing chain had not been checked so recommended that it was looked at whilst the car was here.
Luckily this will be rectified now averting a large bill if the car had seen continued use not only is there a lot of slack in the chain which could have easily jumped, the cam sprocket is the original and is breaking up. All the remains are in the oil pickup filter and the sump.
