They're also known as the PCV valve, Roger, which is a canister that (on my V8) sits atop the right side tappet cover at the front. It unscrews, (I did put up a picture of it, sitting on the bench infront of a tappet cover).
Curiously, I've had this V8 for four years without drama, then it became a drama, despite regular servicing, but now all is....going.
But it been sitting for a while maybe the pump has decided to stop co operating. (As an aside, the pump in my Fiat motor is crap and needs regular attention, but this car also sits for longish periods).

Maybe the engine did not lose prime, but just the cooler empied out over time through the anti drain back valve in the filter. it takes quite a long time for a cooler to refill before you get oil pressure.
If you have a cooler you should have a thermostat in circuit or the oil never gets to operating temp and the water does not boil off. If you have the thermostat be prepared to lose oil pressure momentarily as it opens.
IMHO a cooler is unnecessary on a low stressed engine like a Rover V8 even in hot conditions as long as you use good oil, semi or full synthetic.
They are just one more vulnerability .
At the risk of being repetitive and boring , in 1985 I drove 1980Km from Amman to Riyadh in one day at ambient 45-55C in an 81 Rangie with no cooler with no ill effects using Shell Super 20-50.BUT It used a lot
A 3.9 has a warmer/cooler in the Radiator tank But it is pretty small.

Is the oil cooler a standard fitment on some vehicles? Which? Or an option? On which vehicles?
Does the presence of the oil cooler make a difference to the vaseline priming method?
Thanks,
Roger

I finally got around to priming the oil pump on my 1981 Series III Stage 1 V8 truck. No problems. I packed the pump full of vaseline straight out of the fridge so it was firm. I filled the oil filter with oil (brand new genuine one rather than a Ryco to make sure it had all the right valves inside it). Oil cooler was empty (One hose looked a bit manky so I had it re-made while I was about it). The hard part was getting access to tighten the five oil cooler adapter bolts, but that was easier than loosening them because I had cleaned up the threads. Once started, it took only a few seconds to build up oil pressure. I've just been for a spin and everything's fine.
Thanks all for your help. It certainly makes jobs easier.
PS: the engine number is 12G00083. I think it is the original engine. VIN is LBCAV1AF100092.
Cheers,
Roger
Well done Roger; another happy customer! And another use for Vaseline, makes that 1,002 eh?

Hi also i have rebuilt my rover v8 from my range rover classic! I have packed the pump with vas! But also I have the drill bit for priming it! Can i prime it with the drill bit even if I have packed it with vas? Also which way should the drill spin?
I'm very worried about the pump not priming when i turn the key, that is why I want to prime it before the engine starts
This is my first time doing this so i'm no longer a virgin in this stuff :D

The vaseline needs to be in the pump no matter how you go about priming it .
The drill needs to turn in the same direction as the rotor which will be clockwise or as a normal non reversable drill runs .
When the drill starts to work hard it will be primed and if all is good it takes very little time .

OMG thank you so much I will try that in the morning! You have been a real help I was turning it the other way, I do feel silly now lol.
Many thankds mate:D
