Egnine running away with itself - solved + some questions

if a diesel runs rich, it will just smoke like hell.

if it runs leak, well, its kinda running normally - no throttle flap on the diesel.

if there was no smoke behind, then i would just take it nice and easy for a while, and see what happens.

you lot are mean, the poor bloke thought he'd just run outta fuel and therefore didnt have an engine that was about to kill itself

you could have waited untill tomorrow before you told him the truth

is it easy to check the integrity of the head gasket?

yes, take the head off

but you'll have to replace it with a new one

get the compression tested before you start pulling it apart

Dear God,

Give me patience to keep calm when I hear of diesels running rich, and diesel Landies running on fresh air.

Amen.

I just wish I knew what could cause it for sure. Another thing I neglected to mention was that the throttle mechanism on the lump wasn't getting stuck or anything, so that's not a possibility either.

well it's not going to fix itself overnight, nor will anyone be able to fix it via a forum - get some tests done on it and get your tools warmed up

Here's a small hint for you.

There are 2 types of oil/fuel within a diesel engine.

1) Diesel
2) Engine Oil

If you are out of Diesel, what does that leave?:doh:

ok, just to paint more of the picture. The engine started running on about 500 metres from my friends house. We just got it there and turned the engine off. It turned off with the ignition no problem. Started it up again half an hour later, and it went up to high revs immediately, then conked out after a few seconds. Tried again for some reason, and it ran for a few seconds, then conked out.

if it was running on engine oil leaking in to the pistons, it would be possible for it to keep on going despite the ignition being switched off no, or is that not how it works? switching the ignition off just cuts the diesel supply correct? I hope I'm making sense here.. When putting diesel in the again, I couldn't start 'er up, I had to prime the system with the mechanical fuel pump, so it was definitely out of fuel. Having got more fuel, there is no real smoke any more than normal at start up... no blue smoke, maybe some visible black smoke when struggling at high revs getting up a hill in 3rd.

I'll take it to a garage anyways and see what they think of it

When My TDI is about to run out the revs stay high and revs up until it finally runs out of diesel no matter where the throttle is. Not that It happens all that often I try and keep enough fuel in TBH but I can confirm that it happened to me once too. No other thing except it was low/out of fuel. I know its weird and there is no reasonable explaination but it happened to me aswell.

jai landrover: thank feck for that! you've made me quite happy

I thought Oh Feck when it happened it was on my way back from installing it but it was seriously out of fuel as It revved up uncontrollably not mega high revs but enough to be concerned about. First sign was i let off and it kept going and then calmed down another few hundred yards it did it again for a longer period and then stopped completly. Luckily I had a can in th eboot and primed it up and re started no probs since then no other problems at all. But it worried me at first I must admit. Jai

I asked a Landy mechanic of donkeys years and he said bollix but It happend I was paranoid for ages and kept running it low to prove to him what happened but no joy. I'm not worried now days tho engine seems to be great. Jai

I've seen a TD go up from running on Engine oil and that was mega revs mine was nowhere near as much Revs

well, it's only done 109k. I bet the head gasket is hardly worn in

the revs mine went up to where equivalent of doing 30 in 3rd gear i'd say, so not too bad.. enough to **** me up though, agreed.

........... but then again Jai is the only person who has had a good experience with the Zues timing gear conversion

I've never heard of it before.

The only possible explanation that I could give for it is that the lift pump is pulling less weight in fuel so therefore as the fuel in the pipes becomes less the rate of fuel sucked increases.

the logical arguement against this however is that once the vaccuum is lost and air is drawn into the system it should cause loss of both power and revs. Also the excess fuel would just get returned to the tank.

I must say that the zeus thing does sound like a sensible idea. It does beg the question though.. why don't all manufacturers do it like that?
