Td5 engine thumping noise anybody experience of this????

Background info

I have a 1999 td5 90 with 207k miles on the clock. About 18mths ago I replaced gearbox ( good used purchased from IRB) flywheel and clutch both genuine new parts, spigot bush and genuine release bearing. All has been fine since. Early June I went to pyrenees and before I went changed turbo and fitted new crank pulley as old one was chattering.

Car has run like a dream since my trip of 2400 miles across pyrenees. I'm currently on holiday in Cornwall in my twin axle caravan which we towed down with no problems about 2 weeks ago.

Problems started yesterday when I noticed that the engine on tick over was making a thumping noise that changed frequency as revs changed. I could also feel a knocking through the clutch pedal. When the clutch is fully depressed then the thumping goes away. I have avoided driving it too far for obvious reasons

I took it to a local landrover garage (Steve Toyer) near Falmouth and they have a look and listen. Their best idea is it the thrust washers in the crank have worn and possibly dropped out. This is allowing the crank to move backwards and forwards causing the thumping as the crank moves on and out of its proper alignment.

MANY thanks to Ian from IRB.

as I text him for his opinion as to likely hood of their diagnosis being correct.

and to see if this is a common fault. He did explain that it was not common and most of the time my symptoms point to the dmf but as I have explained above has recently be replaced. ( car has probably covered about 10k miles since fitting new flywheel and clutch). Ian has suggested checking the crank end float which I will do as soon as the rain stops tomorrow.

I asked the garage about continuing to use the car and they said it would be fine for short local trips until next Tuesday when I have booked it in with them. I drove the car back from the garage and the thumping / knocking when the engine was working hard was distressing

and I'm reluctant to use the car anymore as I fear doing more damage ?

I just wondered if anybody else has had any experience of this problem on a high milage td5??

Any thoughts / ideas very much appreciated

Off to hire a car tomorrow so that we can continue with our holiday

Yeah I would try and avoid using it except for real necessity.

By the time I got to the 3rd paragraph, I was also thinking duel mass flywheel. My experience with TD5s has faded in recent years, but I've heard a lot about the DMF.

So the flywheel was replaced 10,000 miles ago, or something else?

I assume they will drop the gearbox down to take a look at the flywheel, but I guess just do what IRB says and check the end float in the meantime... 1998 110 300Tdi White Hard Top

Update,

Have as Ian suggested checked the end float on the crank shaft. I used a bar behind the crank pulley against the steering bar. There is the ta very slight knock as you lever the bar against the crank pulley but not what I expected. I'm really puzzeled to know what to do.

I suppose the dmf I fitted 18mths ago could have been a bad one and be giving these symptoms?

mine has had similar problems after a recent gearbox removal,where i also fitted a x brake turned out the hand brake cable was vibrating on the seat box and still is to some extent but now not as bad i would try removing the hand brake cable and testing the vehicle before pulling out the gearbox etc
hope this information isnt too late, just read the post after being on holiday!

Well I know it's been sometime but another update....

As I thought the fault was with the flywheel I removed the gearbox to investigate.

I was hoping to see something obvious but all looked ok until I investigated end float in crank by holding the flywheel and pulling and pushing it. The video of me doing this is below....

This is where my knowledge runs out. Feeling pretty fed up right now

Is it worth trying to fix this engine???? Anybody done it???

I Have never took and engine apart before??

Any help very much appreciated

Its hard to see from that angle but I am assuming that the movement you are having is the crank moving back and forth and not one piece of the flywheel moving in relation to the other?

It's not too much of a job to drop the sump off (and stiffener plate maybe) and I would have a look in there to see whats happening. I suspect that if you dropped the bottom off you might find something in there.

When moving the flywheel I thought that it may have been the flywheel itself but alas I think it is the crank itself

At the weekend I will remove sump etc and have a look

I suppose when you say you may find something by that you mean the thrust washers ???

If i do is it as simple as refitting them???

Thanks for your comments

It's going to be hard to say to be honest. From memory the sump is a doddle to get off and i'm not so sure about the bracing after that, I seem to remember that it's with the oil pump.

I will have a look at the workshop manual and see what the thrust washer arrangement is..

.......had a look at the manual and it seems that there are two thrust washers, one either side of the centre bearing of the crank.

Even if both of those were missing it still doesn't seem to account for that amount of movement. It might just be the angle of the video or something.

Is the engine in or out?

The only way you're going to sort it out is to fire the bottom off the engine and I reckon the problem will present itself. I fear it may not be good news though, I hope that's not the case.

I haven't got a DMF to hand...

But take the flywheel off and check if the crank itself moves.

If you have no end float on the front, but you have at the back it's either the DMF or a snapped crank. IRB

Dave thanks again mate for your help

much appreciated

Think flywheel off next and then possible sump as you suggest

wizz 80. The front crank pulley and damper was replaced very recently and as new

Ian thanks again mate I owe you a few beers

I will remove the flywheel and see what movement I get then

If it turns out I need an engine ???? Anybody got a good one they want to sell?????
