I see the photos later in the thread.
Cheers DDM

And just to add to the other boys responses, the very last of the D2a's had it blanked from the factory as they used a different fuel cooler and circuit

Any suggestions on how to remedy this? Use a genuine gasket? etc?

It's called horsepower sweat
.......... seriously though, the weeping could be a symptom of rising crankcase pressure, I recall that you have a PROVENT installed, which in effect makes the factory Crankcase Depression Regulator redundant. So if you haven't already done so, consider deleting the CDR and replace it with an elbow fitting and the valves within the PROVENT will regulate the crankcase pressure and the weep may cease - it did for me.

Sir, that long white antenna was welded on the top of the battery guards. LOL.

It was the morning I waked up at Goulburn McDonald, a long towing trip from Bega back to Sydney with a 3.4T combined trailer and Prado 150 hanging at the tail of my D2, and walked back to the car with a hot short black and realised someone fitted that antenna on top my car ;D Couldn't stop laughing at that moment.

You also may need new insulators/bolts as it is the rubber insulator which holds the rocker cover down. They compress with age.

I have been thinking of making up washers from shim material to place under the rubber washers as the bolts are to me quite expensive.
In my case the leak is usually from the little half moon at the back where the camshaft bore was drilled. I have tried lots of sealant, a little bit and all in between but I still have a little drop of oil on the ground.
Also Land Rover original gaskets are best.

I bought new rubbers as well. I don't think it leaks from the half moon. No oil drips at present.

That connector is notorious for rupturing - so I thought it better to delete the dead circuit.
Here’s my go at it .... a random piece of 20mm silicone hose offcut and brass plumbing bits to blank it off.

Ok so mine is still intact.... how does blanking it off affect the flow in the oil cooler and the fuel cooler?

The oil cooler function is not compromised by blanking a “takeoff” point. The fuel cooler coolant flow is unaffected because it is connected on one end to the bottom of the radiator and on the other end it is tee’d into the heater return hose .
