Title: 110 2.5 N/A diesel running problems
Post by: winchman on August 11, 2006, 20:30:18

My mate Stan has spent the last two years restoring a very tidy 1985 110 county, he has ran it every week on his path, but during the last few weeks its been a little bit smokey, but not major.
Well Today was MOT time so off he went only to brake down and to cut a long story and two AA men later its starts and runs fine then all of a sudden the engine races and eventually cuts out. it then refuses to start, but give it a quick tow and off it goes again for another few miles.
Any ideas?
He has put £20 of fresh diesel in  and some Forte diesel cleaner stuff.
At the moment it starts and runs but he wont take it out yet as it dosnt last long.
Any ideas?

1985 County, I assume it's the 2.5 TD then?  You say the engine races in rpms right?  If that's the case then it sounds as though it might be using its own lubrication oil for fuelling.  This can happen when you have an instance such as the turbocharger seals failing, as then the turbocharger pumps oil into the engine cylinders.

But normally when they run on their own oil it will keep revving its nutts off - eventually something goes bang - never seen one cut out on a continual supply of oil.

Sorry its not a turbo and no smoke when its revving.

does it have a catch (sediment) filter on the system, may need draining

if it has a small amount of diesel with a fuel cleaner in it, it may have mixed too much with the diesel, normally with a full tank per bottle with that cleaner stuff

also did you change the fuel filter at all recently

Sonds like the smoke is a build up of oil when it is just ticking over.Think they might be diffrent faults.

I had a very simiar problem on my 200TDi disco...

I had corroded fuel lines so a small amount of air was being sucked in the fuel, at higher revs not a problem but at lower revs it would run and then cut out, no one diagnosed it as a problem I had the RAC out to it when it broke down on way to MOT, I found it when changing the floor !!! so I did away with the sedimenter at the back and fitted new fuel lines all fine now...
