I'm now looking for a new engine. I've had enough of messing with it and I think herself had enough as well.
EDIT
I have sourced a replacement engine €425. It will get rid of the guess work and just put it on the road. I'm sick to my teeth of second guessing myself. If it doesn't work I can always bring it back.

There will be a way, for instance:-
In edit mode, click on the text, it opens your keyboard. Just above the keyboard, there's a toolbar. If you scroll to the right (you push the toolbar to the left), you'll see 2 u-turn arrows. Those are the undo/redo buttons.
I only use my phone for texting and as a camera so can't confirm.

Oh right, didn't know that thanks for that. I obviously didn't read your post properly the first time.

I personally wanted worry about that crack as nothing has failed and it won't be causing the running issue you're having.

When you said you were taking the covers off, I assumed you were doing just that and not taking the cam out as you were only looking to set the timing and needed to know which valves were up and down?

So easy to go down a rabbit hole be that a necessary one or an unnecessary one.

Hi Roger, you have to pull the cams to set the timing on the chain. I ended up bringing it to a machine shop and he said it was cracked and could fail. I can't afford to get stuck off the road once this has been put on the road.
I priced up a head €250 and a further 40€ for the valve cover which on these engines is the upper part of the cam journals.So nearly €300. So then I said how much is a complete engine €350. So I just bought the engine which is now sitting on my drive way. I will perform a leak down test off the car first to make sure it is a good engine.
If it passes I will be happy to to fit it and any new or better parts I will swap off the original engine.
It turns over by hand freely with no injectors in it and a healthy sounding put put as it cranks over from the injector ports. i need to go through it and make sure everything is ok with it. It looks like the timing belt was only done on it before it was scrapped but I will put the new gates kit I bought onto it assuming it passes the leak down test.

I know you are probably thinking I must be nuts and at this point I do agree. I just don't have any other option at present.

The new engine has a y type doseur does anyone know if there is any reason why I can't just swap my straight doseur on to it.

Both engines are RHR engines. The chap said there was evidence of scarring and oil starvation on the journals as well.

Maybe I’m being thick here as you move mentioned a timing chain now. I assumed it would be a belt but irrespective surely you just needed to pin the cam and the other points to know whether the timing belt is wrong.

Maybe chain is for twin cam? I’ve no idea but obviously you cannot have a timing chain and a timing belt.

And a timing chain would not slip but you did think the belt had stretched.

So I am a little confused and yes I do think you’re nuts! 🤣

But in a nice way…

I certainly wouldn’t have stripped all that out. I’d have diagnosed the issue and scoped everything to reach a conclusion and then ran it until it either blew up or didn’t!

You sound unsure of the ‘new’ engine. Swapping things across sounds like a recipe for going around in circles to me.

Nahhh, think we're all roughly as daft as one another round here! :lol:

I admire your determination and despite set backs you keep plugging away at the damn thing. I wish you all the best of luck with the new engine and look forward to a bright sunny day in the future when it has finally behaved.

Speaking of sunny days, make sure that "new" engine is very well wrapped up whilst it's out in the weather on your driveway. Pallet wrap is pretty good and cheap.

If it's like the 2.2 and the 1.6 16v HDi engines= timing belt runs one camshaft (and water pump) second camshaft is driven opposite end by a short chain between the two camshafts.

Cheers for clarification Matt. I imagined it would be twin cam.

I know Roger but if I can prove the engine is good before I fit it by testing it I would be more confident than running an engine with a crack in a journal.well we all drive french cars so of course we are a bit nutty in a good way as you say.

Yeah same design with the cams. I know what to look for mechanically, so if the new engine is healthy and I install all the parts I know are good on mine I should be good. Hopefully it will be up and running soon. I'have a big heavy tarp over it so it should be ok.i have a lot to do on it to get it fit for installation.
The usual breakers engine everything cut. So strip, clean and transfer loom and ancillary equipment after I have tested it mechanically. My only concern is the amount of oil on the back of the engine but it could be from cut pipes.

I think it's becoming OCD with that car to be honest with you.

"We choose to go to the moon" type approach. I'm the same. I want to be able to fix it because I want to be able to fix it. All as daft as one another! :)
