dude i hate to say it but i smell BULLSHIT. I bet it's one of those workshops that when they **** something up they tell you something needs replacing and **** you over money-wise. or if it's like battalion motors here in conberra they will do it on purpose.

can anyone back up this theory of oil causing a timing chain to skip??? cause i'm pretty sure the likeliness of this is about 0%.

that must be annoying as dude, how does the car run? have you driven it since they said this?

there should be a way you can check it yourself too, such as comparing the position of the harmonic balancer to the position of the cam gears using TDC?
