Okay so far my recently acquired 300 Tdi D1 has been spectacular, haven't had a problem.
It's also got a Bee Utey diesel gas fumigation system installed. It is a manual and a '96 model.
Used to belong to Big Guy on this forum...bloody brilliant vehicle it is
Anyway I've taken it on a couple of pretty long drives already and it hasn't skipped a beat. Tonight I was driving it over to our cousins place for the first time to show them the car since they are big 4WD enthusiasts and he owns a nice Patrol but used to be a Rover guy (and I think still is deep down). We drove about three quarters of the way there and stopped to pick something up from the shops. When I got back in the car and started it up it made a horrible loud clatter for a short second and then it went away and ran normally, it wasn't a noise that I'd ever heard before and it sounded bad, like a really loud diesel clatter. So I got suss and stopped the car, looked under the bonnet to see if anything was stuck in the fan or something stupid and tried again and got the same noise but like I said the car ran fine after it started with no noise. A really dry sounding noise almost like it was lacking oil on startup but then after startup enough oil got around the place and it was fine.
Anyway I started driving again hesitantly but got to my cousins place okay. Mind you when we stopped we'd been driving for about twenty minutes already and had already stopped once to fill up on LPG. We drove the rest of the way (probably another fifteen minutes) and no problems. When I got to the cousins I stopped the car and started it again to see if it was still there and it still made the noise.
Went inside and came out with my cousin the former Rover guy and tried to start it but only this time it wouldn't start at all. Gave it a bit of accelerator pedal and after a while cranking it over it started up okay with a giant puff of smoke out the back so it seemed like the engine was well flooded. Ran as normal after startup.
Went inside and had dinner then came out to go home afterwards and again it wouldn't start, gave it some pedal and it puffed out a huge cloud of smoke and started...but no horrible dry rattle this time.
Drove it home no issues and I'll try it again in the morning but maybe by then someone might have given an insight as to what might be going on. I tried searching but only found info on Td5's making a similar noise.
I'm going to be driving it interstate on a band gig trip in a month or so so I need to make sure it's all spot on and I'll happily take it to Ritters to have a look since it just got a decent service from them but if anyone knows what it might be maybe I can save myself the trip.

The diesel clatter sounds like detonation.
Have you tried turning the LPG off?
Could also be an injector issue.
Also - does the glow plug light light up? What does it start like if you turn the ignition on till the glow plug light goes out, then off, then repeat 3 times, then try to start???

Don't stress about the glow plugs, mine have not worked for about 4 years and it starts on the coldest days with a bit of white smoke.
I know i'm going to get flamed for it but I only found out when I did the head gasket and found they had been disconnected and the last time I had disconnected them was about 4 years ago and must have forgotten to reconnect them.
Anyways, on pulling them out to have the head crack tested, I tested them and found none of them to be working, so I put them back in and forgot about them again
It sounds like it could have copped a bit of air in the fuel line, or in the pump for some reason, I have had similar a couple of years ago after getting some bad fuel and having to flush the lines and pump.
May also be bad fuel or a bit of water in the fuel passing which is not very good and you may want to drain your tank and just check as that can cause some pretty nasty damage.
I don't know why it would do it on starting only though once running these things will just about run on anything.
Would it be possible for the Dgas to be feeding the engine on start up by any chance, making it harder to ignite the diesel due to an over rich fuel mixture in the combustion chamber??? Just a thought...

LPG on or off doesn't make a difference, in fact I think Bee Utey might even chime in and say that the LPG doesn't do anything on start up anyway, only when you're driving and you press the accelerator does it inject some gas...that's my understanding anyway.Originally Posted by isuzurover
The glow plug light does light up and then go off like normal and I did the "on off on off on off" three times before trying to start and it didn't make much difference. In fact just then when I did it this morning I couldn't get it to start at all. Almost as if it has a flat battery (even though I've got two of the things with a red arc isolator and both measure fine) it was cranking but started to sound tired and wouldn't fire, then I smelt a funny smell and looked at the exhaust pipe and a small amount of white smoke was trickling out. When I bought the car Frank told me that I might want to change the main battery sometime soon but I wouldn't think that would account for some big nasty clattering noise on start up.

Haha oops about the glow plugsDon't stress about the glow plugs, mine have not worked for about 4 years and it starts on the coldest days with a bit of white smoke.

Don't know if it could be bad fuel but I filled up last about 400km ago and it's been running fine since, the only thing that changed just before it started happening last night is that I filled up the little tiny LPG tank...then when I stopped next and started again it made the noise. I would have thought if it was bad fuel it would keep playing up even after it started not just on start up...?
Master
Thanks for the replies...I honestly don't know a lot about diesel engines yet but maybe I'll learn quicklyI might try jump starting it later on and see if the battery is a problem because I know some of them can be stuffed even if they show up okay under a multi-meter...as soon as they get load on them they die. Something ain't quite right though, but I'll get to the bottom of it!
(or someone at Ritters will)

Yes, that is how it should work, but it may be malfunctioning.
The clatter you describe sounds like detonation - e.g. you get noises like that if you use aerostart on a diesel.
You should be able to tell if it is cranking slower than normal??? Have you put a multimeter on the batteries?
Diesels just need fuel and air to start.
The injectors deliver extra fuel during starting.
Master
Hmm so what if the glow plugs had started playing up would that mean that it wouldn't start the car when it should and the injectors would keep pumping fuel into the engine thinking it had started but it would just get flooded.
Hmm sounds like there could be a couple of possibilities...might go out and try to start it again now.
Master
Okay so it won't start at all now...still cranks over a couple of times trying to start but it won't fire so it sounds like the battery is okay. I'm going to have to start it somehow to get it down to Ritters on Monday if I can't sort it out before then...are there any other ways you can get a diesel engine going if it won't start normally? Like roll starting a petrol motor...will that work with a diesel? Mine is a manual...
AT REST
It sounds like your injector pump isn't pushing fuel. Did you get low on diesel? Check the fuel shut-off wire at the injector pump. They can fall off or come loose. You should hear the fuel shut-off "click" when the ignition switch goes to "on". Check the air filter hasn't swallowed a rag, or an intercooler hose has collapsed.
As for the lpg system, pm me your phone number and I can talk about it. Emailing takes too long to explain it.
