TD5 power loss.

**scando** · 7th August 2010, 06:53 PM

G'day guys
I've had a bit of a serach around and haven't found anything that quite matches my issue.
I have a TD5 Defender (99), Around town and on short highway trips it has been fine, but today, the first of a longer tour, I have been experiencing some problems.
The motor will just shut down for a moment, the engine light comes on, breifly then the car begins to run again quiet happly (All gauges turn off when the engine dies and come back on when it restarts.). The second time this happened the engine light stayed on when the engine restarted, but went out when I pulled over turned the car off completely and restarted.
I have noticed a noise comming from the heat exchanger on the right hand side of the gurgling/ squelching motor which may or may not be related.
History, I have just replaced the fuel filter and was a little suspicious that there may have been air introduced into the systrem (fuel pump sounded "off" the first few times I ran it (jsut the fuel pump)

Anyone have any ideas?

Thanks
Cameron

Air in the fuel system, could be the O-ring from the old fuel filter stuck in the housing, causing a gap (2 O-rings)

OR
oil in the injector harness

OR
head gasket (gurgling is an air pocket in the system)

OR
Oil cooler leaking fuel into the sump

Thanks for your reply Redback!

I'm now in Charlivlle, was the nearest largish town. Dose anyone know of a Rover specilist out here?

This morning I drained the bleed on the bottom of the fuel filter, bled the fuel system using the proceedure in the handbook, and the car ran fine for about 80km beforerepeating the symptoms.
I have replaced the injector loom recently, and there is a little oil still coming through to the computer (wimping the conector out over the last few weeks has produced only a few drips of oil on the rag.)
One thing I did notice today was that the fuel warmer is leaking a little coolant but only when the car is cold.
I knew I should have bought a scanner for the computer.

Thanks again for your help

Maybe air is getting in somewhere.

Just an update for anyone who has a similar issue. I'm now back in Brisbane and it would seem that the issue was actually a poor earth to the computer.
The gurgling noise is from the fuel cooler and I am reliably informed by the lads at MR Automotive that this noise is perfectly normal.
