The oil in it is exactly what Landrover specify though?
I haven't got the money for a full pump refurb which it might or might not need. £18 for a gasket set I'm happy to risk it to change the O Ring, if it works great if it doesn't then the pump needs a refurb and I'll have to fork the money out.
As I said it's a genuine 79k from new engine.
I checked the oil properly today and it hasn't used a drop, still sat bang on 'H' I did 70 miles in it today and it absolutely flies, it easily gets to 80 (on a private road officer) and apart from the initial blue cloud on first start which clears in 30 seconds it doesn't smoke at all, not even black smoke and no the pump hasn't been tweaked. I gave it a beasting today to get the engine working just in case it's glazed bores.
I'm now wondering if with the oil on H not N and the fact it's parked facing downhill for weeks at a time some oil is getting into the bores because parked outside my house facing downhill it shows as quite a bit above H (almost an inch above), I've also been told by a few diesel specialists that poor atomisation on startup can also cause blue smoke hence me wondering about the diesel pump.
As a test I've parked it on the flat in our car park tonight (I just hope it doesn't get stolen!) if there's no smoke it's purely down to being overfilled with oil and parking it downhill.
