Hi everyone,

I recently bought a 123D for my wife. Nice car but we are discovering a few issues.

We had a valve cover leak which I got fixed but we still have oil burning smell entering the cabin. I disocvered that we have a weird smear of oil/diesel just under the swirl flap actuator.

Its near where the EGR enters the manifold and sprays up under the actuator and across the alternator. It doesnt smell all the time but comes in wafts.

As you can see its pretty thick and gunky near the ball where the plastic engine cover mount



Before I go ripping the intake manifold off. has anyone got any ideas where this is coming from? I suspect it is congeeled Diesel rather than Castrol Edge

If the EGR is gummed up can it cause the EGR cooler to manifold seal to blow by?
