Oil leak - Rocker Gasket??

Click image to enlarge

Help Please! 2011 Defender 90 Pickup 2.4 TDCI. 33,000 miles. Engine picture and picture of oil leak just under exhaust manifold.
Leak seems to come from just below fuel injector manifold and above exhaust manifold. Then it leaks all the way down and drips off bottom of oil filter and sump. Only leaks when running. i.e. does not drip on to driveway when standing. Other side of engine totally clean no leak at all. My hunch is rocker gasket leak, but would really like some wisdom from the forum is whether this makes sense? Is it a known issue? hard to fix?

Thanks to all.

I had this but with equivalent leak at the intercooler hose on the drivers side as well.

Turned out to be the turbo oil seal, so new turbo. Upgraded the intercooler for the big BAS one at the same time and then treated it to a stage 2 remap.

Every silver lining and all that....

My car went into a landrover specialist on Tuesday for the repair. He reckons it was injector seals pressurising the rocker cover gasket. Try taking the oil filler cap off and check to see if there’s a lot of pressure and a chugging sound. That’s what I was recommended to do. The repair was around £300. Seems to have stopped the leaking so far.

If anyone is looking to buy new injector seals I found the best supplier to be MM4x4 nr Droitwich. They supplied me with four off for less than £20, made by Elring. Other places charge £11 each for them!!
