Have you looked at the rockers ?
That's all plugs out and average of 3 attempts on each cylinder?
They should all be within 10% of each other.
If still out then rotate until both valves are shut and blow air in the adapter and try to hear where it is escaping - inlet or exhaust or past the rings into the sump ... Best keep an eye on the expansion tank, just in case.
Maybe try the bosch super 4's always made a big difference on the older petrol cars
Update
Put ol in bores and all ok apart from No 4.
Either rings gone or valve not shutting
The plan is to put borescope in to see if bore is scratched by broken ring and check the rockers
There may also be a 4.0 engine available,
Is that a straight swop does anyone know?

Back in my day you had to spend a ton of money on stroker kits, boring cylinders etc to get more displacement. Technology these days...

Post #28 "a 4.0 may be available" I don't know much but the 4.6 uses CAN for the gearbox but I doubt it will be a problem.he mentioned replacing the engine with a 4.6.. unless i misread
Fit a nice reliable diesel

How reliable will that be? You can have your engine rebuilt vy V8 Developments for about £2.5k. they seem to have a hell of a waiting time at the moment though.
I'll second that. V8 Developments are doing a full engine rebuild for me but doing the complete job of removing & replacing the engine which costs a lot more than £2.5K. They have had my P38 since last August & hopefully I will get the car back sometime in the next month. Their original promise to complete the job was October/November last year
MrGorsky has been waiting since last June and still no engine. His wasn't even anything complex and we took the engine out so simple as can be for them. Apparently they're booked solid until October so that gives an indication of the lead in time.
V8 Developments have had my car since last August but I paid a £1,000 deposit to reserve my slot last June.
I think you're getting a bit ahead of yourself, depending what needs doing. There's Turner engineering too although there have been a few horror stories with v8s there in recent years. They may sell a refurbed head complete with valves or something like that though if it is just your valves and rockers that need replacing.
V8 Developments are here: www.v8developments.co.uk
Well worth ringing and talking to them. They're very straightforward and helpful.
I heard a rumour they won't even take your car on until October now because of their backlog. It'll be a few months there depending what you want them to do.
