Land Rover starting q
Hello
I'm posting this more in the spirit of enquiry than anything else, and I know we have a few LR fans.
A friend of mine has bought a 2nd hand turbo-diesel LR (I don'[t know the model). It starts ok when cold, but won't start when the engine is warm. Starter motor operates and the engine turns over.
He told me yesterday that after a week of this, he checked the coolant level and found it was nearly empty. I think he may have compromised the HG in such a way that a warm engine loses compression when starting.
Does this sound likely?

Check for the simple things first - quite possibly an air leak on or near the fuel pump. I had a very similar problem with a ZX, started perfectly when cold - could not stsrt it for love nor money when hot. Eventually traced the fault to a perished 3 way pipe connection under the pump - new rubber & some silicone later and all was well once again.
is it a smoker?
If the compression is low when hot it will spin over rapidly on the starter and belch clouds of white unburnt fuel. I would have thought that it would fire eventually when the glowplugs reached a high temperature.
If as Mart suggests its air in the fuel - then it won't inject much and there won't be much smoke!
If its a turbo diesel as opposed to a TDI (85 BHP as opposed to 111BHP - the more powerful engine is direct injection and may not use glowplugs for normal cold starts) it amy have been subject to a recall for defective piston rings. Apparently the suppliers couldn't get the proper grade and used a harder metal - and guess what - they all failed. Turbo-diesels were made a long time ago (85 - 90?) so this was probably cleared up ages ago.

The earlier Turbo-diesel engine is also known for having utterly awful compression, and "venting" like there's no tomorrow. When this happens, it can be very hard to get a hot engine to start due to naff-all compression.
Unfortunately when this happens, the engine is pretty much at the end of it's life. To check, once the engine is running and up to temperature, pull the crankcase vent pipe off and see how much it vents. It'll probably be venting so hard that there's spats of oil coming out too.

Hi folks
Thanks for your contributions. I ran them past my mate, but he is going to take it to the garage to sort out. He thinks the immobiliser may be stopping it working at high temperatures so I'll let him let them sort it out. No doubt I'll be hearing loads of stories about how useless garages are and how much more expensive it's turned out to be.

Not in this case.cavmad wrote:If it`s any help I think some shared the same engine as the LDV 400 commercial which was sourced from Peugot.
The engine that was shared between Land-Rover and the LDV van was the V8. Diesel engines in Land-Rovers have always been Land-Rover engines. Which is a shame, as a Peugeot engine would have been significantly better in many cases. Some people have retro-fitted Peugeot engines into Land-Rovers, but they never came like that from the factory.
Will be interesting to hear what the final verdict on this engine is, as I have a feeling it will either be something tiny, or a written-off engine.

The perkins T4.108 from a montego is a brilliant engine to shove in a landrover, and you have to wonder why Land-Rover themselves never made the connection.. after all, the engine was available in about 1986, at which point the best Land-Rover could offer was the 2.5 diesel, which was based on a design from 1956.......
The other popular engine swap in Landies is a perkins 4.203 or 4.236. I have one of each, and it has to be said they are silly engines. 60-70bhp from nearly 4 litres is ridiculous. More torque than a Pug 1.9TD, but at 1600rpm. And they top out at 2600rpm. Not nice to drive.

Update:
According to the garage, it was a camshaft sensor for the fuel pump that was malfunctioning when the engine was hot.
My mate had this repaired, a full service, and a couple of pads.
Guess how much.
No, more than that.
No, more than that again.
GBP1099.00 Kerchinggg indeed!
