well sounds like your making progress - do check the wires are connected when its light outside, as you know i was messing in that area last time i messed with her (water pump replacement). All the belts are brand new so if you ultimately need to change the alternator you don't need to replace the belt, its done a few hundred miles tops that belt ;)
 
Ordered a replacement alternator anyway, as the last thing I wanted to do was have a look on saturday, find all the wires were where they should be and end up having to buy one anyway. £39 so not going to break the bank. Fingers crossed!
 
Was going to say in a way I'd only replace the alternator with a new part as in my opinion it is one of the worst jobs to do, not the kind of thing you want to do twice!

Way I did it, was inlet off then remove the heat shield from the back of the alternator (held on by 3 nuts iirc) and then there is literally JUST enough space to squeeze it out.
 
I swear down, the more I look at this car the more ridiculous things seem to get!

So, to my eyes ePer suggests that the inlet and exhaust share a gasket:

Now from what I can see from above, that further suggests to me that the exhaust manifold is held on by the lower 4 studs, the inlet by the upper 2, and is then attached to the exhaust by 2 smaller bolts from above to give stability, as shown below.




I've drawn red boxes around the studs that I presume (read: hope) are the only ones holding it to the head, and circles around the bolts I presume merely hold the inlet to the exhaust for stability.

On the assumption that all of this is correct, the problem I now have is that I can get a tool on the first of those nuts, but I can't turn it! Seriously FIAT, what the hell?!
 
HULK HANDS TO THE RESCUE!!! :)

mmm, at this point your guess is as good as mine... Need someone who has actually taken one off to come along.

The loop thing in the way though, can that not come off? Take the long horizontal bolt out and i'm guessing there is 1 or 2 more you can't see in the pic

See I thought about taking that off, but it also appears to be supporting that uppermost pulley (PS pump?). I'll have another crack at it tomorrow and take that off unless someone else (J.R Racing?) knows a better way!
get a 17mm spanner on the nut for that power steering bolt at the back of the hoist eye bracket then 13mm rachet dpanner on top bolt and very slowly remove bottom bolt with normal 13mm spanner and remove bracket....for the gaskets to becrenewed its a big job....exhaust manifold comes off too.....im doing this now in mine for the second time so know the doos and donts.....on a cold engine disconnect fuel lines from fuel rail.unplug all wires around the inlet inckuding phase sensor and oil pressure switch.remove inlet support bracket.disconnect throttle cable from inlet. Split smaller crankcase breather just above the nonreturn valve thats just above thermostat.feel behind the inlet feel for 2 x10mm bolts that hold heatshield over ther exhaust mani. Youll also see 2 at the front.also 10mm bolt holds on a smaller shield by the turbo.that shield has to come off before you can lift out the main shield.youve got 7 nuts holding both manifolds onto the head.13mm socket on a short extension bar with your rachet down behind the inlet from above.crack nuts off.the tricky ones are at no.1 piston end.pull off vac hose from 3 way valve just in front of brake fluid reservoir.disconnect blue fuel vapour return line between power stering and brake fluid res.
Remove black fuse cover from bulkhead.
Fuel rail can stay on the inlet.just unpkug the injectors.pull loom through to the right hand side out the way.unclip the main loom where its held in position to give more wiggle room.remove 10mm bolts holding dipstick to rocker cover and remove earthing wire.
Remove 2 more 10mm bolts on left dide of inlet and remove earth wires.now the loom can all come through.
now the fun.....you need to push the inlet off the studs.its tricky.lever it and sort of twist it round and off.....ill stop there for now.let me know when you get this far.....

BTw u sure the gaskets need changing?
Itll be very noisy with loud ticking sound if the gaskets gone...i would squirt some wd40 onto it from a cold engine see if it bubbles....
 
I'm not changing the gaskets, I'm changing the alternator, but in order to get it out (and the replacement in) I have to get the inlet manifold out of the way. Not touching the gaskets, however blu73 mentioned that one of the exhaust mani studs is missing so it's an excellent opportunity to put that back while the inlet is out of the way.
