I think the last on the list of jobs for me to do for LH side is to take the EGR valve off the LH side, then take out the exhaust manifold bolts in order for me to take the head off completely. Is that correct?

To gain access to the EGR/manifold bolts I will have to go in through the wheel arch? Once I take the the plastic inner wheel arch off will I see the heat shields that have to come off first? Thumbs Up RRS 2.7 HSE Stornoway Grey

You may not need to remove the plastic wheel arch. I didn't in drivers side.
Probably best to remove on passenger side though

Yes you need to go in through the wheel arch.

I can't remember exactly but remove whatever is in your way and there is lots of it.

There is 1 or 2 large turbo pipes which need to be loose to move about to access bolts. Oily.

I know a long 1/4 " extension is handy 30cm?

You probably need to unplug the suspension height sensor.

Egr off 8mm
Heat shield off
Undo manifold but it stays in place.

You then lift the head upwards off the 2 dowels and then when free, move into the center of the Vee

Don't forget to unplug cam sensor first at front.

Don't know if you can see this pic,
doesn't show much, apart from silver turbo pipe loose .
EGR off
Possibly manifold off too, and I was changing the turbo too

Thanks Andy. That gives me a good idea of the next list I can hopefully tackle soon. Thumbs Up RRS 2.7 HSE Stornoway Grey

Got most of the heat shields, EGR valve, height sensor, remaining plugs etc; off... but I'm struggling a bit with the last bolt on the manifold, it's the bolt that is at the bottom and nearest the bulkhead.

There is a pipe coming from the turbo that is impeding the remaining manifold bolt. Can I take this pipe off from the turbo, it looks like an oil pipe with a banjo/torx connection. I can get a torx bit on it no problem but the pipe itself is also spinning a bit, just seems a bit fragile to hold a bar against it to to then undo the torx/banjo bolt. RRS 2.7 HSE Stornoway Grey

Oh yes. Yeah you can remove the oil supply pipe.

The other end is on a flexible pipe, so don't worry if it flaps about.

I guess you need to do what you need to do.

I did it from the top using a 3/8" drive, but maybe you haven't got access.

Can be seen in this pic

Once removed, put a pug of tissue in the top to prevent dirt getting in.

Same goes for the large turbo connections. Newspaper or kitchen towel just to prevent all the rubbish getting in
(and keep metal nuts out !)

Great, thanks Andy. That gives me a bit more confidence to put more ooomf into getting the last turbo pipe off, as I wasn't aware it was attached to a flexi pipe. Thumbs Up RRS 2.7 HSE Stornoway Grey

OK, so far the six manifold bolts, the turbo oil pipe banjo bolt and the turbo flex rubber pipe (the one with the jubilee clips) are all off but the manifold still feels very much stuck to the head. I tried prizing the manifold away from the head and it comes away from it very little.

Is there more to strip off, possibly the cross over pipe bolts to come off? or should I put more force into trying to move the manifold away from the head. Thumbs Up RRS 2.7 HSE Stornoway Grey

I think the manifold can stay there. You have ensured it is loose. (which is good)

Need to wriggle the head free and into the V

Head bolts out, head now off, you were right though did take a bit of wiggling to get it free... phew!

I have head sitting level on bench and doing a visual inspection on valves, along with sitting some fluid on valves, just to see if it disappears. How else do I determine if valves are bent.

I am at the stage now where I need to decide if 2nd hand head is way to go or try and replace damaged head parts within original head.

Any valve marks on pistons to give clues?

I got an £8 motor cycle valve compressor/ remover off eBay.
In red box. Used it to remove valves. You should be able to visually check the inlet ones then.

Cleaned up pistons best I could but don't see any visual marks on them.

I have access to one of those compression tools to take out valves so I was planning to do a rudimentary test on each valve by taking it out and sticking it in a drill and spinning it to see if I can visually see it as bent or rolling each valve over a completely flat surface such as over plate glass to see if any of them are buckled. Not sure this is the best way to fully test them out but should give me an idea of the best/worst of them?

Is there a sacrificial weak point in the design how these heads are set up. What I am asking is when I took the rocker cover off initially there was a couple of broken bolts that attach the bearing caps and also a couple broken roller finger rockers. Would the force of the bump when it all broke at first do any damage to the camshafts or is this designed to just break at the weakest points. To be honest I was expecting to see the valves in worse shape than they are sitting just now Thumbs Up RRS 2.7 HSE Stornoway Grey
