When I tried with the lever out it made the starting worse, the temp was about 0 when I was trying.

I managed to get a few hours on the van today and took the silencer and timing covers off,

the belt and tensioner are fine the timing looks ok by eye, certainly not out by any large degree.

So I may take the sump off tomorrow and see whats lurking inside there!

I found a couple of "lost" oil filler caps in the shrouding, one for a turbo and one for an early non turbo!

Cup of tea, and a warm now

John

Good idea, just draining the oil might give a clue too..

Timing belt edges not frayed and sitting fairly central on the pump sprocket?

The belt has been rubbing on the inner tin cover more than I would like, but nothing really, the tin cover is slightly out of true, but wouldn't account for the noise.
I also found a strange heatshield on top of the turbo down pipe, which is loose, but again not enough to make a big din!!

Quite common I think, but if it' the belt itself trying to run off the sprocket, this may indicate the pump has been removed/adjusted and not set back quite true... do check that all the securing bolts and screws are in-place, partic. the one at the back (front of vehicle) which is difficult to access (a taper headed bolt holding underneath of the output end of the pump to the block bracket)

That is standard JX pretty sure, but prob. well past its best now...

HarryMann wrote:You can check where the cold start lever and pump control arm are - the cold-start on JX diesel, I believe, both richens as well as advances the timing... the lever is to the left of the pump when looking from the rear (between the pup and block, hard to see easily), and should I think be pulled right back towards you to set it to 'off', normal driving...

Here's a picture of where it is. Can you see the wire between the two injectors? (Ignore the red circle - I was trying to show someone where Glow-Plug 3 is). Infact the top of the red circle touches the wire in the picture.



Hope that helps.

Perfict pict, thanks..

NB. That wire is often missing...

I managed to get a couple of hours on the engine over the weekend and have finally found out what it was!

Tough bottom ends on the diesels. I think the previous owner had lost the oil cap and improvised with a paper towel.

I took the sump off and found a shredded paper object in the sump, this had blocked the pick up to the oil pump and no. 2 big end had over heated.

The shell had melted and spread out causing the squeaking


The original owner is a 70 year old "motor engineer" bless him!

So now I need a new crank and rods at the very least!

Well done... your first instincts were correct and mine weren't

What a nitwit... a paper towel!

Somebody will have a crank lying a round - but postage from here a bit stiff methinks...

NIce natural history piccies in that newspaper BTW !

2nd thoughts inspired by PC52... yes it looks like a lot of the rest of the engine will have suffered too...

1.9 AAZ or a 1Y from the local scrappie might be a lot cheaper than buying a whole assortment of bits and gaskets and then finding something elee has suffered?

I've a couple of options, I have access to a scrap 1.6 turbo block with a good crank, so I thought of swopping them over, a bit of work but minimum expense!

Or the bodger in me wants to emery the crank and conrod and pop a 2nd hand bearing in (it couldn't be new ) Anyone want to donate a set of shells for fun?

and see what happened........

But seriously the van cost 150€ and is at the stage where it is either saved and improved or quickly passed on.

I have plenty of other projects, but I have fancied a nice clean bus for a while now, so we will have to see!

The cam looked ok, turbo ?? bores looked ok, its not oily inside the exhaust, and the debris never entered the oil system, its localised to the sump.

As far as I know the bearing going stopped the vehicle being used.

Thanks to all as well for all the input on this it was most useful


John

Well if there's nothing to be lost, other than a gasket set and a few shells...

I'd mic that journal up first see how much its ovalled - I'd use old emery tape, not new and polish the journal afterwards and use new shells.
Not sure if those 1.6TD b.e. caps need new stretch bolts, most of the 1.9s do.

New pump, fill it with cheap oil and change oil and filter after 5 minutes idling, then after a run up the road again

Only time wil tell...

Check the timing! if it's out or if it's wrong you will bend valves!

Rattling is often normal on these engines when they are cold - especially if they have hydraulic lifters on them.

Have you ruled out slipping alternator belt for the screeching sound?

If/when you get it running try cracking off the fuel pipe nut a little on one injector and listen for a dip in engine rev - tighten it up and move to the next one - if you get a cylinder that does not alter the engine note when you slacken off the fuel nut then either the injector/pistons or valves could be suss.

really sorry to hear/see that

a paper towel ffs

good luck with getting it sorted

Dug, he's sussed it, read the thread above...
