More Disco.. what's going on?

So 2 weeks ago ... overheated. Not sure what happened there. I filled up and bled the system and all has been well. Heater is working fine and water level has held solid.

Then there's been the problem where it won't start 1st thing in the morning. That led to a local garage taking it away and fitting glow plugs and breaking one off.

Overheating was suspected water pump as there's been a canary singing from that area which doesn't go with wd40 spraying.

Yesterday I noticed that the serp belt was tattered on one edge. So I bought and fitted a new belt ( this one had only been fitted in August ). I watched it for a few seconds and on the bottom main pulley off the engine the belt jumped a tooth and was over the edge. That pulley was wobbling. I took belt off and checked that pulley. Loads of play.

So I refitted old belt ( didn't want to kill new belt ) and drove to a local garage that works on Landrovers. He said that these pulleys have a rubber bush and it was probably worn and that pulley needed replacing. So that now needs doing. How big a job is that? Expensive? How do I get it off as a spanner just turns pulley.

I go to Liverpool to watch Frankie Boyle and when I return to car a tyre is flat as. Anyway just put on spare and home we go. So that tyre needs sorting.

So today the car was booked into a local engine rebuild place to have that broken glowplug removed. The guy phones me to say that he's managed to drill the plug out. He said he'd had to fit an insert kit but it was now done. I picked it up and there was swarf all over outside of engine. I drive home and at about 1200 revs it sounds like a machine gun ... DAT DAT DAT DAT. I phone the guy up ( it was closing time @ 5.30pm ) and of course he says that it couldn't be anything to do with what he has done. So I say that the engine has been fine for 15 years but the day that he has been drilling into the head it starts sounding like an AK47?

I ask if any swarf could have got into the head? He says it shouldn't have done but if it had it would have been blown out of exhaust. I've said I will take it for him to look at tomorrow.

To be honest I've driven it tonight and either I've got used to it by now or it's got less noisy. It's still sounding DAT DAT DAT at @ 1200 revs and then seems to disappear with the engine noise at about 2k revs but it doesn't seem as bad as when I was driving home.

Any comments or ideas on either the pulley problem or the noise?

Cheers

Is it a 300 tdi ?
If so the belt tensioner is probably knackered.
The noise must be a piece of glow plug in the cylinder, which should eventually work its way out the exhaust hopefully.
Did have a rattle on my TDI once it was one of the valve top spacer things that broke up.

I'd need to hear it, to be honest.

Yes 300 tdi but there's defo a prob with the crankshaft pulley. That pulley is wobbling all over the place and isn't lining up properly.

woodruff keys fubared?

The crank pulley's the one held on by a nut at 400 ft lbs of torque isn't it? So long as you can undo this, its an easy job. I remember no worries removing, but when it came to retightening it I snapped by 1/2" breaker bar! Philosophically, I decided it was tight enough even though I'd not actually achieved the required tightness.

Yes that bad news get it looked at be for it gets stuffed right up.

may aswell do the timing belt while yer in there because chances are its fooked the crank pulley and bit a chunk out the crankshaft and mite of even had a nibble at yer cambelt pulley

Why bother giving people advice? And why keep taking it to cow boy garages?

"cowboy garages"

After that garage broke off the glowplug I took it to Dales in Burslem. They are regarded in Stoke on Trent as THE place to get diesels fixed. EVERYONE in Stoke tells you to go to Dales. So I went to Dales to ask them if they could get that glowplug out.

The advice I was getting on here was either to leave it on 3 glowplugs or get the head off myself. I've never attempted taking a head off anything so I didn't think it would do any harm to ask the 'experts' Dales if they could get it out without removing the head. They said that they don't touch broken plugs but send all those to Allards in Hanley who are experts at doing this. They do thousands.

So I went to Allards at the weekend. They said that they do loads of these and they would ' have a look ' on Wednesday. So I dropped it there today. I asked him how much it would be before I booked it in. He said to just drop it off and he would take a look. Next thing he's phoning me to say he's got it out.

So I'm not purposely taking it to cowboys. These are supposed to be the best places in Stoke.

Maybe Landrovers aren't for me? Maybe I've been unlucky? I dunno.

One downside to that masterpiece is that next down the pipe is the turbo and thats not gonne appreciate being fed swarf at any speed.

I'm not too sure what you were meaning Dave, but the glowplugs are on the drivers side of the engine and the turbo and it's pipework are on the passenger side?

i think he is saying that the turbo is powered by exhaust gases and any bits being ejected from the combustion chamber go thru the turbo. Not sure it would be that catestrophic, but not recomended.

Quote; "but if it had it would have been blown out of exhaust"

I meant that if their idea was that any swarf and bits of plug went into the cylinder, if they do make it past the exhaust valve, the next thing in line is the turbo, this will most likely disagree with being pelted with bits of plug and swarf.

Hello there Col, sorry to hear of your continuing troubles, but to at least one degree you have brought it on yourself.

When we spoke about the broken glowplug I said to you to leave it as it is - as it will be safer than having it drilled out and messed with. As for the glowplug "expert" saying any swarf will just get blown out the exhaust valve well that's just lazy crap!!

The only way to be sure that there is nothing in there is to take the head off !!

Re the crankshaft pulley (Torsional damper) it is a composite of rubber and steel and sometimes - as it sounds like yours has, starts to come apart. This needs resolving quickly to avoid any other damage. Go to your nearest scrappy and pick one up for next to nothing, as a brand new one is listed at £122.81+vat

Dave

Yup I get it guys ....

The new guy who has just bought his first Landrover has probably been stitched up by blokes who may not have done it the way you lads would.

It's a week or so before Christmas and it's been just a tad cool around here lately. I need the car to pick children up from train stations coming home for Christmas and to buy trees, presents and all that nonsense. It's not the perfect time for me to be educating myself in the wonderments of DIY Landrover repairs and start stripping engines.

In hindsight I should have just left it on the 3 glowplugs until it was more convenient ... but hey ho ... clocks don't go backwards. I'd hoped that the guy would whip out that glow plug and that would be one problem solved.

So ... anyone else want to join in the gloom and doom ( I'll even provide my own crucifix and stakes ) or any chance of some advice on what to do next?

The car started first turn this morning and as far as I can tell the noise has now gone.

So I'm left for the moment with this pulley. I suppose it's take it off and see if the keyway is trashed?

Can I leave this for a couple of weeks or is that going to cause more damage?

Cheers

( Sorry for the sarcasm but it's been a nightmare year with cars ... just buying everyone else's problems ... but I suppose that's what you get when you are paying peanuts ).
