BTW running much better in terms of throttle response since blanking off the AGR valve, especially from cold........ I have sourced a very cheap plastic manifold with the correct agr valve, would it be worth swapping that over, considering how gunked up the current manifold is? Thanks

So what are you saying Wammers, do you think if I replace the MAP sensor that may help, would like to sort that before offloading it, I'll check that out when I can find the inclination Thanks again

Hi Keith Thanks for that, I thought Nissans were good, what year was yours. I have done loads to the P38, new bags and shocks, radius arm bushes, alternator, starter motor, front oil seal, blend motors and engine cooling bits new tyres etc I think I will be able to pass it on with a clear...

I thought there was nothing left to fix or replace..........but it is a land rover!!:)

I feel a newish X trail is on the way, my "cheap car" didn't work out, cutting my losses...... I'm turning Japanese shocking!! I agree I've become a wimp, but I did spend most of the winter underneath it on my drive.....so not too wimpee

I'm bottling out...........as soon as the car is fixed, I'm selling it

Bit fed up with it all really........driving my 993 need a break from the RR. I think all that is OK bob, as far as I remember when Steve kindly put his computer on my car boost pressures n stuff were good

All done.........still loads of black smoke when revved to 4k (off Load)....... I guess a trip to Wimbledon is on the cards!!

Great, thanks Wammers will do, as per Robs suggestion as well. When I stripped the engine down to get at the timing sprockets I had to get the gaskets from BMW........ Thanks again

Also what are the two hoses inlets for? There is a good strong spring pressure holding the valve closed.

Ok so here is the EGR off the vehicle, the valve seems pretty jammed but haven't cleaned it yet, is it usual for it to be so scuzzy in the manifold....... Thanks everyone for being so helpful.......and patient!!

Wammers, yes that sounds bang on, strange that the exhaust gasses cool the combustion process, always thought the exhaust gasses were raging hot!! Grrrr may give the expensive fuel a shot, but I think it's a little more complex

Thanks Keith I guess from what you guys said earlier, that it is malfunctioning and not closing would a good clean sort that or will I have to replace it

Thanks Mark I may well give those guys a shot. Would it help to blank off the EGR valve........or would that just cause more problems Ash

I have that engine in my car (2001) but it does have EGR, may explain why I have a few problems, haven't got round to cleaning out EGR valve yet and I do get crankcase mist if I take the oil filler cap off

Penguin and Blackstrat Thanks, the air filter is new and the hoses are in good condition The erg valve is pretty scuzzy I shall clean it and have a fiddle

This thread has gone slightly off topic........ must've been dull Thanks everyone....... get the spanners out, again

^^^^^^^^ Poor guy just rebuilt his engine too......... how would you stop that runaway? Mind you mine is not unlike that, but in black!!!

Yes Data, it has been run down from London to Cornwall quite a bit so should be fairly clean of deposits. It's a pain, as someone commented these cars are a hobby rather than transport........ In fairness it has been pretty good London to Cornwall and back comfortable and quiet transport a bit...

Thank you Wammers
