It's retarded, pump timing is out. Bosch or Delphi pump? Bosch, do rear entry method, delphi, side entry with 90 degree adapter.

 

[normspanners]

If it was causing problems heads wouldn't be getting skimmed at all.

In fact Ford say that certain heads should not be skimmed for this reason.

how can you say that ??
they are pinned from the pulley sprocket and that should be close enough for it to run.

At the end of the day these are basic piece of p*** engines to work on.!!

It started with a tow and is puffing white smoke, it's retarded... He fooked up somewhere - we've all done it.

Some XUD-9 don't have the hole in the bellhousing for the crank locking pin in my experience, he might have it a tooth out.

It started with a tow and is puffing white smoke,

so what does that prove / it will still white smoke if the clearances are tight because it is still unburnt fuel, it would have started on easi start if it was just retarded because that has nothing to do with timing and all to do with compression.
All towing does is raise the compression and heat the cyl's more until it is forced to start .

 

[normspanners]

OP Please,
I am getting a little fed up with this now,

IT is simple, just check the clearances it takes 5 mins, then we can discuss it further, it is not rocket science.

PS

It's a single cam with a keyed sprocket so can only be in one position and has a hole which you bolt it to the head and the pump has two bolts all have to line up for the pin to go into the flywheel so i can't see how it could be wrong

I have never put a pin in the crank on one of those or most engines tdc is tdc, they are usually a pain to get to, I check it with a vernier with the head off and tipex front end, simple, or if it is impossible with the head on I have a snap on tdc finder or the old way is to fill the cyl with oil and watch at the injector hole then wash out the cyl afterwards with diesel

Hi, the thing is skimming heads is a historical practice from the days of side and overhead valve engines which are more tolerant of this. Just because it's been done in the past does mean it can still be done regardless. OHC engines can and do especially Peugeot for breaking cams and cam caps or carriers.

Colin

This is going well O/t and my apologies to the Op for that. But I couldn't let that statement go without comment. If skimming heads is a 'historical' practice then I'm a dutch man, because its going on in workshops all over the world every day.
Norm, as for Ford saying you can't skim their heads - well they will say that wont they, so they can sell you a nice new one. If you didn't filter out the manufactuer BS then non of us mechanics would be remotely good at our jobs.

 

[normspanners]

Norm, as for Ford saying you can't skim their heads - well they will say that wont they,

Ford say that only on certain models.

Well yes we do skim but it is not always the 'correct way' hence A/M head savers etc but the fact is you cant argue the fact that cams dont break, coz they do, the old vauxhalls were one that did it regularly, after a head warp and skim, it is a chance you take, by your previous posts, you respect Eric Hammonds, work, who i do do work for, ask him his views on it, as said, he and I have discussed this at length and ways of getting around it.
It is a fact that doesnt go away. I have only had a couple but I will say that I try to check for tight cams.
It is my view that, Customers should always be warned of the fact that this could occur, in case it comes back to bite YOU the garage owner on the backside, after all it is not your fault they overheated the car in the first place. But it is your fault if you dont warn them.

Just because it's been done in the past does mean it can still be done regardless.

It is my view on colneroy's historical point was, that in the past mechanics have just had the head ground flat regardless how much, that being on low cam pushrod engines, because there is nothing running in the head and is usually no problem, and that factand practice has stuck.

Now You should not just have a head skimmed regardless because of the fact of warp-age. and in fact 2-4 thou is the max in reality after that you are well into the realms of bending cams. Now this head has been skimmed before and we dont know by how much, and now has had to have 19 thou off it to flatten the face, that means the head is bent at least 20 odd thou, you do the maths.

19 thou is a decent amount by its self and I doubt that it only had 1 thou off it the first time so you can bet that the camshaft bearings are out of true whether they have worn already allowing for previous warp who knows it's a gamble some pay off some fail, I've had heads skimmed with no problems but there is always that chance

Ok the cam rotates freely when torqued down, I will be checking clearences on the valves and rechecking timing I've talked to a bloke at work with some diesel experience and while he doesn't know my engine his words are just retensioning the belt can pull the pump timing out once running again on some engines.

Valves were not removed.

It's fitted with lucas injectors and the pump looks like a lucas but has a Delphi tag.

Does any one have or can point me to a detailed setup for these as the Haynes I have for the engine doesn't cover a Delphi pump and also states it's a cast iron head so not very trusting on the information I have in it.

I think all points above have merit and i appreciate all advise on this as being a bike mechanic diesel is very far removed from stuff I do know.

It's retarded, pump timing is out. Bosch or Delphi pump? Bosch, do rear entry method, delphi, side entry with 90 degree adapter.

Bloke at work also said sounds retarded.

I was following the instructions i have and with the head off 1 & 4 were at TDC as they should be.

Will check Autodata tomorrow, see what it says.

Of course it is it's an LDV! If they had stuck with Ford engines I might have stood a better chance and the short time I did in a pug dealer I drove a Boxer but only ever topped the fuel up everything else was done in the workshop the bit I didn't work in the 11 months I was there.

1-you must use a pin through the front of the crankcase behind the starter to lock the crank
2-does it have one of the injectors with a 2 pin electrical cable on it,if so did you put it back in the cylinder it came from?
tappety?this is valve to piston interference- see (1)
also check the keyway on the crankshaft gear as theres an issue with them shearing

just friendly observations,as i used to work as an engine technician/builder for a reconditioners for years.

1 yes I did.
2 no it doesn't.

It's a tappy noise but it is not 100% constant and some parts of the rev range sound really good, it also is not progressive with revs, sort of sounds like a tappy CVH but combined with a exhaust blow out of a slightly loose manifold that rattles a heat shield.

I have

already posted autodata timing belt data in post 68

It's a single cam with a keyed sprocket so can only be in one position and has a hole which you bolt it to the head and the pump has two bolts all have to line up for the pin to go into the flywheel

I was following the instructions i have and with the head off 1 & 4 were at TDC as they should be.

By that statement Are you now saying you didnt pin the crank?

 

[scotb]

did you have the banjo bolts off the fuel lines at the pump? did one look different to the other?

 

[normspanners]

Just seen the post sorry you did pin it, is it white smoking badly all the time ?
because if it was one tooth out it would bellow smoke all the time.

 

[rich the mechanic]

did you have the banjo bolts off the fuel lines at the pump? did one look different to the other?

No I didn't only thing I did at the pump was loosen the unions to move the pipes out of the way and then bleed it.
