I recently had a burnt valve on a 2.5l 10V. All the work has been done
to correct this. Initially everything seemed fine. Now a week later I'm
getting sluggish performance. There has been a concern over the exhaust.
When a hand is placed over the exhaust pipe oil is deposited onto my
hand. Does this suggest a piston ring problem although oil wasn't
deposited on my hand prior to the work or could it be faulty valve seals?
I have used more oil than I would expect in just one week's driving
although there was previously an issue with the rocker head seal. This
was also fixed during the major repair work to the valves and head.

Many thanks
Tony

My guess would be they forgot to install the valve seals on one or more
valves, or the head gasket has a leak between an oil passage and the
combustion chamber.

The sluggish performance is more of a worry though, best get them to look at
it again, they must have overlooked something or made a mistake.
