    If you're itching to keep going with it rather than waiting for the post, I have a set of E-Torx sockets that you're welcome to borrow.

    I wonder if the number stamped on the injector is different to it's location because someone swapped them over to see if the fault moved cylinder, if they were thinking it was an injection problem. Process of elimination type thing.

    Hi John.
    Did you break up the flaps or was that how they came out ? mine came out whole and i cleaned them up just to see how much damage had been done to the ends which the rod passes through.

    From this photo you can see the build up of gunk, not good at all.

    Manifold is in the barrel ready to be washed out.

    Removed the MAP sensor also to give that a good wipe over.

    I broke them out. I couldn't be bothered to clean them, as they were going anyway. So I just twisted them to snap the plastic, and out they fell.

    I'm going to give the inlet manifold a quick clean, but it's a job I'm not looking forward too. I'm still undecided if I'm going to blank the EGR or not.

    Thanks for the offer, but the replacement E-Torx sockets will be here tomorrow, and I'm taking time off cars today. ;)

    I'll get to it later in the week, after work.
    That has crossed my mind too. I just seems very suspicious that all the injectors are new, and all were in the correct sequence, but starting at the wrong end of the engine. It makes me think that someone got the cylinder order wrong, which could mean the coding is also wrong.

    It might be a bummer that the fault is so serious but it's a big result getting newly refurbed injectors. Gotta be worth around £600 alone. :)
    It looks like someone spent a lot of dosh trying to sort this before giving up and trading it in or selling by auction.

    That's what I told the wife Ali. ;)

    The most annoying part is she found a set of second hand injectors for £100 which I wouldn't have bought, had I known it already had a refurbished set.:mad:

    From the top of the head all looks ok, but something is preventing that one valve from closing, but that'll wait till later in the week now.

    You can sell them on and should only make a small loss on selling fees so no biggie. ;)

    Or keep them in the spares box, just in case?

    Hi John.
    I am just about to go out and jet wash the manifold clean, i blanked my EGR off as soon as i got it, in hope it will have kept the gunk down a little i will know once i change the manifold over for this clean one.

    Re the injector numbering, they are back to front ( for me anyway) with #1 to the right, easy thing to mix up.
    i always default to #1 at the pulleys

    I'll blank mine off, as soon as I assemble the engine.
    Yes, the numbers are revised, compared to the standard numbering method, where No1 is at the cam drive engine of the engine, but on this Ford/PSA unit the cam drive end is No4.

    Ok, so today I decided I'd remove the head with the wrong socket, rather than wait until the E-Torx. I figured that I'll be replacing the bolts anyway, so it doesn't matter if they get damaged by using a standard socket. I found that an 11mm hex fitted well enough to release the bolts, which is good enough for me.

    However what I saw when I lifted the head wasn't what I was hoping for, it's ugly folks. :(

    The problem was that No2 piston had obviously had the crap smacked out of it, :eek: but by what? 20200802_163212.jpg 20200802_163232.jpg

    By this, which was sitting at the edge of the chamber in the piston crown. 20200802_163420.jpg
