Hi,

Thanks for the tip. My remote had stopped working after a weak battery replacement and syncing worked fine!

Final UPDATE.....

Just got the car back from a mechanic friend, and it sounds as sweet as 

Changed all 12 lifters ... £180 for bits, and £180 labour + new oil and filter.

Most of the lifter were stiff, but a couple were locked solid and worn on the top surface, so that was definately the problem noise.

I don't think the Wynn's would have sorted them, but you never know.  Better to change them I think.

Let's hope no more problems for a bit 

Old topic I know but your video shows the exact same problem I've been having for some time now. No mechanic I saw was able to determine the origin of the problem so thanks!
Has the fix been durable then?

Again, many thanks!

Omega General Help / Re: Faint ticking noise fault 82 [2.5TD]

« on: 05 August 2012, 19:29:59 »

Right. A nice person lent me some tools and I could start working. Real PITA was that the wheel was of course blocked. Anyway, success!
The problem was not a worn key or drum but the blocking piston securing the barrel at its end stop which was not free to move because of a dent in the housing. Methinks this is a poor design or my example was badly cast perhaps. I could file the drum to recover normal operation. I was asked a hundred times if I was leaving my spot! Another nice guy running a fun fair attraction nearby gave me some grease to finish the job. Phew!

Now I am left with the 82 error and a sometimes lit EML. This number 4 injector was the only one that was not changed but refurbished. My Bosch diesel specialist has special tools to repair those: they keep the sensor but replace the needle. False economy perhaps...

Anyway, advice please!

Well the keys are the new ones I got with the new drum last year. Is there any way to make the key move? I can't even get the drum out.
And I'm stuck on a car-park.

What are the odds?
Now I can't turn my ignition key!
And it was changed one year ago! 
And still away from home!

Omega General Help / Faint ticking noise fault 82 [2.5TD]

« on: 05 August 2012, 10:37:33 »

Hi,

Well the title says it all. I noticed an unusual ticking noise at the top of the engine a few days ago.
Then, yesterday, the EML started to light up for a few seconds after startup. The light goes off after 10 seconds.
A paperclip test reports fault 82 only.
The tractor apears to run normally, but the noise persists.
The question is: can I safely go on using her?
What should I do? Of course we are away on holiday...

Many thanks,

Jacques

Omega General Help / Re: Running 2.5td without viscous fan?

« on: 11 January 2010, 19:05:56 »

Note, if the stat is working properly, and the rad is working properly, the viscous should have zero effect (other than wasted noise/energy), unless working hard at low speed (towing), even then, leccy fans should be able to keep up.

Indeed, if the aircon radiator isn't obstructed! In hot summertime, they are always on anyway! (okay I live in Burgundy and I go to Midi on holidays)

I strongly maintain that you should clean the aircon radiator before doing anything else: it is all important to keep a good airflow through both rads. And since the aircon one is first on the path, it seems pretty obvious to do it first, doesn't it?
My thermostat was changed too, but this had no effect on the behaviour of the viscous clutch.
My temps are 92,5 with fan and 97 without fan. But what is important I was told is the fact that the needle should always be right in the middle of the scale (at noon for BMW owners). The temp shown is probably wrong anyway... I could not keep the fan out in summer, no way, but this was before cleaning the rad. These are the normal temps, and 80 (pre-facelift) always shows a bad thermostat, or a new one probably fitted the wrong way—or defective. Is your heating working properly? On mine, it is fully operational after 5 minutes' drive, which is normal according to BMW people.

Hi,

Well I never could run without my viscous fan. But then I found out that an obstructed (they all are) aircon radiator prevents the air flow to reach the clutch, hence never disengaging the thing, unless the weather is very cold...
The solution is to interpose some plastic sheet between the two radiators and karchering out the mud and bugs that have invariably accumulated there through the years.

Hi,

The intercooler fan and the aircon fans all work together, there's nothing you can do about it!

About the aircon radiator, it can be really badly obstructed with all sorts of bugs you know, but anyway it's always seemed absurd to me that a radiator could be in front of another one...

As for  the b****y viscous fan clutch, I now think you can't really do without. I've seen my temp gauge reach more than 100°C without it, really frightening isn't it, but it never passes the 92.5 limit with it.
But then I live in France, and I spend some of my summer holiday in the deep south!

I'm on my fourth defective new viscous: I have to run it at 3000 rpm for a few seconds to disengage it every day. But it does remain silent for the rest of the day!

Hello!

Normal running on mine is around 92 on the gauge. Show it a good climb, and it'll rise to the 100 mark, but once over the top, then it'll quickly return to 92.

Last year: New rad, 'stat, and water pump made little difference, even with both electric fans running.

Exactly!


As some of you may know I tried very hard to get rid of the viscous fan assy but although my radiator wasn't stilted or anything, I couldn't go up steep slopes without engine temp going up above 100°C, no matter what.
New coolant, new thermostat, new pump, nothing worked. It just isn't safe nor reasonable to do without.

I guess Opel made a mistake in designing their aircon radiators whose holes are too small to let the flux of air go through, not to mention the fact that after a few years' use, it is literally filled with dead bugs and mud.

All I could find to get rid of the annoying reactor noise was to get the engine run at 3000 rpm once or twice to disengage the fan. Not nice. BMW keep telling me their clutches are okay.... for 325s and 525s maybe!

Hi,

By the way, my EGRless 2.5 TD passed MOT today.

Okay then,. I'll end up changing the fan itself if it comes to that. I shall keep you informed.

The problem is the thing is always engaged, whether hot or cold.
The other day I pulled over after a one hour  drive and when I put my hand between the fan and the radiator, the latter was completely cold, not even lukewarm! After a minute or so, the radiator became lukewarm, then I started the engine and it became hot quite quickly. So theoretically, the viscous clutch shouldn't have  been engaged at all, since it's temperature-sensitive. The air flow is so powerful that it always keeps that part cold. Puzzling, this.
