Any assistance appreciated

Hi everyone.
New member, not long signed up and done quite a lot of searching....
Just hoping some of the more experienced owners can point me in a better direction to try and get my truck running better!

I'll try and describe problems and what ive done to now.

Bought car as a non-runner with broken starter motor an leaky sump and generally tatty.
Managed to repair starter and get running but unfortunately doesn't run very well!!

Will start fairly quickly, but run very rough for 10 secs and stall.
Start again and try to keep slight revs, to stop stall, after 30secs to 1 min will idle roughly with a lot of white smoke (street full according to missus!) once warmed up and driving white smoke is much less obvious but will not rev over 3000 rpm, very slow to rev to this, car appears to be in limp mode, no turbo spooling.

so far, I have changed fuel lines for 8&6 mm, as had been replaced with pipe that was to large (10mm both lines). once done could not get to start again, no matter what amount of bleeding, etc. Fuel was making it to pump but not to injectors,

Ended up towing jeep to get going, and will now start.

Read thread on the return valve on the pump which sounded exactly like my symptoms, but once managed to convince the valve out, All appeared to be normal. My valve had a slightly different design with an end cap. One thing I wondered was if the spring could be weakened?

Believe car takes longer than it should to warm up than it should, from reading another post, and fan is running all the time the engine is running. Not sure If this is normal?

Hoping others have had similar issues and can point me in the right direction.

Any advice / help much appreciated! :bow

Many Thanks

Marc

The 2.7 fan runs all the time, someone will clarify, prob normal :thumb2

I'm on here a lot, but my mechanical knowledge is limited, especially for the 3.0

The gurus will be along I'm sure :lol

White smoke is usually a sign of water due to head gasket failure.
It is possibly linked to running on veg oil and fuel filter needs replacing. Possibly water in the tank too.

Fan is normal on 2.7.
10mm fuel lines won't hurt it.
Glow plugs might be knackered.

Nope, this is the 3.0 - doesn't run on veg unless I'm mistaken.

 

[Peasgood1]

Nope, 3.0 doesn't run on veg but couldn't see the bit where you said what engine it is.

Ehehe i think the fact that I put 2.7 may have thrown you off a little :augie

 

[Peasgood1]

No, I honestly couldn't see it.
Never thought to look under profile pic. My fault.

The 3 litre will run on a 25% mix of veg oil, so someone may have used it to excess. Not sure if there's a mini filter but worth a check. Sounds like some fuel was originally getting through but not enough to run it well and then not at all. Also check for air being sucked in through leaking joints or pipes. Any fault codes?
Good luck with it. David.

I see that no one has mentioned the fuel filter leaking.

The 3.0 litre could be different, but any 2.7 td or tdi, with white smoke, I would say that the filter is a cheap one, and has not sealed correctly on the top face.

White smoke to me, indicates air in the fuel line. As this is what happened to me, when I bought a cheap filter.

Still, it could be something else of course.:nenau

Run a cheap inline filter with a temp tank in the engine bay. Or a cheap inline filter with a primer.

Here's my cheap filter and priming bulb. Works a treat and I can see what's going on through the glass bowl

 

[firebobby]

My one takes about a mile to see the temp gauge start to stir, the fan will run all the time as it's designed to, unless someone has fitted an electric fan.
As has been mentioned, try the fuel filter, I always fit genuine filters and don't have issues with them, unlike some after market items.
Does sound like a fueling issue though.

You say it starts fine but only runs for a short while, together with white smoke suggests to me the glow plugs are fine but the device that keeps them on after the light goes out is not working (not sure how it is done on the 3) the way I check this is to use a DC clamp meter on the wire, the 2.7 draws around 60 amps (depending on make off glow plug) and after a few seconds drops to around 40 but stays on till the engine gets warm, suggesting it is controlled by by the ecu and temperature reading, Rick

 

[solarman216]

Re the fan, it is a viscous drive so on first starting and giving it some revs it should roar quite loud and after a minute or so should go quiet, if it continues to roar it has failed, Rick

Does that have a 1 way valve?

This can also be monitored by using the ECUTalk software as there is a sensor on the glow plug relay

I just thought, my 16 pin Serial adapter should be here this week, so I'll be using my mates 51 SWB Commercial as a guinea pig and report back, cable was only £4 all in so I'm not hopeful but it's worth a punt

I wouldn't mind that :lol, sounds like a beast when it roars

yes it does

but takes around 5 hp, Rick

Rick, my fan roars when starting off, but still turns as the engine is running, both my 3.0 and old 2.7 do/did this.
I thought that's how the viscous part worked, still turns, but not under the same load as a standard fan ie: you could stop the fan with a bit of wood :nenau

 

[Craig8661]

im woundering is the 3ltr direct injection ie high pressure fuel line to feed the 4 injectors. seen it with the rovers where the injector has let the pressure of the fuel rail causing simula problems

yes that is correct, perhaps I did not explain it very well, to bring the fan out of idle state when the engine gets hot, what happens is a bi metallic coil spring on the front of the fan hub turns a pin opening a path for the viscous fluid to circulate causing the fan to run at full speed, unfortunately the pins can seize up so they do not come in when hot, the fact that the fan runs at full speed on start up does not prove that it will work when hot, it runs like that because the fluid has collected at the bottom and takes a short while to to pump itself out, Rick

I think you mean "common rail", no the 3 Ltr is conventional indirect injection, the pressure being around 2000 psi, common rail is around 20 to 30 thousand psi and the injectors are electronic valves, Rick
