Thread: Defender 130 TD5 Saga

Hi Dave,

When you say Black plastic welsh pug, do you mean the oil filler cap?

I thought even if the cap wasn't in they wouldn't throw out oil? (will go and have a look on mine shortly)

Also I am suprised that it got anywhere that could affect the throttle control. Another point on this is that in every case I have seen with driver demand problems on TD5's I have not seen one that fails with it revving. It always just cuts the pedal. (Be interesting if anyone else on here has, Bilknight..?)

Did it turn off normally on the key? When it was restarted was it revving, or idling normally, or idling roughly? Was the engine mangement light on?

Hope he gets it fixed, and there are plenty of knowledgable people on here who will be able to help.

I am not the most mechanically minded when it comes to Land Rovers. If you take the black plastic cowling off and look at the front of the rocker cover you will see a black 2 inch "plastic" plug. It blew out and the oil followed.

The motor kept running with the ignition switched off. We had no warning lights showing. The first time it started after checking it it ran ok but blew alot of white smoke. We ran it for a while untill it happened again. To stop we "popped" in 3rd gear and jump it.

We rang Land Rover and they said not to try and start it again. They said some motors have kept on running untill they blow the only way to stop it would be to diconnect the injectors.

There could also be more of a drama because the engine oil smellt of diesel.
I am still keen on getting one as it preformed well when it was running. How ever I might look for the more basic diesel motor without the computerised electronics.

It will be the sealing plug directly in front of the camshaft.
I can't say I've heard of one falling out though. It must have been quite loose to do that, in which case it would've been leaking for a while.

don't be turned away by the td5.......go the 300tdi

in saying that there are many a member on here that have had no problems with there td5's, all cars break down at some time

running with the ignition off is a very bad thing...

Diesel in the oil isnt good either. It sounds like the injector seals have failed.

Disocnnecting the injectors wouldnt stop it in that case either.

You would have to try and stall in in 5th gear

is it the plug shown below?

The plug is shown bottom right hand corner.

I havent heard of a TPS failing so that the engine revs on But its technically possable although I would think of it as being very very unlikely.

For that rubber plug to blow out (or any plug on the td5) you would have to have had significant blowby as they breath pretty well. Id be whipping the rocker cover off ASAP and findnig out whats what. Its within the realms of feasability for the cap to suffer enough oil saturation that its vibrated out but I wouldnt have suspected it.

If it didnt shut down as soon as you went to key off and you had to stall it then youve got problems, IF theres diesel in the oil its more than likely and injector seal let go.

I'd thinking that and Im not a fan of TD5's and not up on all the rubbish that comes with them but it sounds to me and tell me if it's possible Dave or someone in the know :

a. Leaking inj seal feeds Diesel
b. A failed turbo bearing seal allowing oil to be fed into the intake system post turbo and maybe pumping enough air into the crank case to blow the plug.

I have seen similar on Transits before as well as a Fiat dozer with an after market turbo and they will just run and run until they run out of oil and sieze.

The big problem with the Dozer was that it was Hydraustatic so it couldnt be stalled and we had to shove a jacket into the intake to kill it.

I do have to say..........this isnt a TD5 specific problem, pretty much any Turbo diesel engine could do it.
