Highly recommend to do the Best4x4 PCV mod listed here: https://landroverforums.com/forum/di...4x4-mod-92942/
At the age these trucks are at, the plastic pieces inside the valve covers have become clogged and very brittle. I purchased the Sankei KP-111 from NAPA in the PCV mod thread and have not had any issues in the year it's been in. Don't do what I did and keep the driver-side plastic baffle in (which I got a new one for as the old one was clogged and brittle). I think that caused a crankcase overpressure issue I experienced and popped the front main seal out and against the crankshaft pulley. Remove both of the plastic pieces
Edit: @Best4x4 , you beat me to it.

I did the PCV mod and it was really easy. Just be careful when you work on the valve cover end. The connector is pressed into the valve cover and with a few wiggles and a pull, should come right out, Removing the plastic spiral inside of the vent tube was a bit tricky for me but I did drill it out. Take your time and you'll be successful!

How many miles on your truck, what octane gas are you using, if cheap gas, yes the PCV can be plugged if good gas, chances are it isn't plugged.
How tight did you tighten the v/c bolts? When done, go power scrub the engine to get all the old oil of it, don't use soap or degrease just cold water and then watch to see if it is still leaking, if it is, you will then need a new set of v/c gaskets.
