I recently got a friend to change the timing belt and water pump for me, whilst he was doing that he noticed oil leaking, seemingly from the turbo area and there is alot of oil in the exhaust too.

I haven't been driving it much until I get it sorted (heading to a garage later in the evening) but I have noticed that it is guzzling diesel something shocking!

Any ideas what it could be? Really hope the turbo isn't banjaxed and its just a pipe needs replacing
