retromlc Posted October 2, 2011 Report Share Posted October 2, 2011 I have a 1989 2.5 TD and i only bought it a couple of weeks ago,all seemed well,had to sort a few things,but now as it idles or sometimes changing from 1st to 2nd it starts to climb through the revs as if i've pressed the accelerator flat to the floor and the only way to stop it is to kill the engine,a large amout of smoke comes from under the bonnet,i inspected it and when I rev it manually as the revs die back to idle there is some smoke from the turbo manifold,anybody got any experience/idea whats up? thanks in advance Quote Link to comment Share on other sites More sharing options...
-Mongrel- Posted October 2, 2011 Report Share Posted October 2, 2011 (edited) It sounds as though you may be getting oil/fuel into the intercooler, somewhere in my distant memory I recall something about diesel getting past the rings and diluting the oil which then gets sucked up through the crankcase breather pipe (it feeds vapours from the crankcase into the intake to cut down on emissions) into the air intake. First thing I'd look at would be an oil change, and if the oil is very thin and 'diesely' (I think I just made that word up!) then maybe a compression test would give you the info you need. Edit: OK, a little more Googling has thrown the following up, quoted from an article by Glencoyne Engineering (article in full HERE ) ... 2495cc turbodiesel, overhead valve, type 19J: Given the strength and reliability of the 2.5 diesel, you can understand why Land Rover thought it would cope with turbocharging, but the result was a warranty nightmare. 2.5TDs can fail in any number of ways, but the most common seems to be internal cracks developing in the cylinder block. This gives the same symptoms as a blown head gasket or cracked cylinder head, but is not repairable. Due to a defective design of crankcase breather, these engines also tend to dump large amounts of engine oil into the air filter housing, which turns the paper air filter into a soggy black lump. This in turn leads to oil being drawn into the air intake, causing the engine to 'run away' and self-destruct.

elgreco Posted October 2, 2011 Report Share Posted October 2, 2011 I had a freelander td4 which the turbo bearings went allowing oil to be drawn in causing the same thing. Tom Quote Link to comment Share on other sites More sharing options...
Paul223 Posted October 2, 2011 Report Share Posted October 2, 2011 bin the td, they really are not worth spending a penny on, and fit a tdi, which will add to the vehicles value Quote Link to comment Share on other sites More sharing options...
retromlc Posted October 2, 2011 Author Report Share Posted October 2, 2011 bin the td, they really are not worth spending a penny on, and fit a tdi, which will add to the vehicles value that@s what I've heard Paul,problem is i only bought it 2 weeks ago so I gotta see what trader says,I paid good money for it and don't want to be the one paying to put it right.

Tom This man is right don't drive it again. When the seal goes properly you are lucky to be able to stall it then they go bang in style Quote Link to comment Share on other sites More sharing options...
canthitathing Posted October 2, 2011 Report Share Posted October 2, 2011 I had a freelander td4 which the turbo bearings went allowing oil to be drawn in causing the same thing. Tom Deffo I had exactly the same with my TD defender a few years ago. Changed the Turbo and everything was fine after that. Quote Link to comment Share on other sites More sharing options...
jacksdad Posted October 2, 2011 Report Share Posted October 2, 2011 Its trying to kill itself, leave it to it and then buy a Trooper! Quote Link to comment Share on other sites More sharing options...
mick miller Posted October 3, 2011 Report Share Posted October 3, 2011 Its trying to kill itself, leave it to it and then buy a Trooper! Is that so he can throw all his money away on a pile of ****? A Land Rover without an engine is still worth more than a crapped out pit of depreciation like a Trooper. Back to the trader, get it fixed or returned fella. Good luck.

retromlc Posted October 3, 2011 Author Report Share Posted October 3, 2011 Well I had it checked today and it's not the turbo,based on what they can see has been replaced it looks like it's a problem that someone has been trying to sort,they thinl it could be the injector pump,which is mental money apparently.I'm gonna ring him tonight and see where we go,I'd throw it back at him today except it's a 400 mile round trip,not so easy.i'll keep you posted Quote Link to comment Share on other sites More sharing options...
al4x Posted October 3, 2011 Report Share Posted October 3, 2011 won't be the pump on your description, if it revs till you stall it its running on engine oil hence the lack of engine governing, you've been lucky so far it will do it again just make sure it doesn't run out of oil as consumption will be high and when it runs out the engine seizes Quote Link to comment Share on other sites More sharing options...

mrwabbits Posted October 4, 2011 Report Share Posted October 4, 2011 (edited) 1st .To diagnose and elliminate the turbo being faulty ( though you said someones checked it). Remove air intake pipe from turbo (manifold side) and see if it is wet with engine oil inside pipe. If it is - turbo u/s - renew. If not wet, move on - check next thing. ### Note: 2nd. Try renewing the fuel lift pump or fitting a new service kit to said lift pump +. (Low pressure side - prior to injector pump). At same time, renew fuel filters and check no sludge in system. Fit new parts - bleed system - And renew the throttle return spring at pump end if its looking tired and slack )-- ## A Faulty diapragm +/or valves in lift pump can sometimes create this type of engine surge.## Should do the trick And damn sight cheaper than a new injector pump. 3rd. IF ... it still does engine rev surging after doing that , disconnect throttle linkeage and start engine,( H+S - make sure no loose items or fingers in way of moving parts ) Manually rev engine + hold at different rpm levels,,, if surging and high revving persists -- consider suspect faulty injector pump governor. If so , its an exchange pump i`m afraid. Edited October 4, 2011 by mrwabbits Quote Link to comment Share on other sites More sharing options...
stokie Posted October 4, 2011 Report Share Posted October 4, 2011 When the revving starts does the pedal stay down as you said it revs ok from the engine bay . Just trying to rule out the obvious that's it's not a kink in the throttle cable The TD really is a bad engine and worth replacing with the 200tdi as it's a straight swap But as you just bought a lame one then I would speak to the dealer that sold it to you and see what they are prepared to do . It's probably a cracked piston as that's also a common fault that dumps oil into the intake check for contamination in the manifold then you really do need to do a compression test Quote Link to comment Share on other sites More sharing options...
