I did check for you, but promptly forgot. :p It will be interesting to see how removing manifold through the top goes. With turbo removed it would be pretty easy to get manifold out the bottom I think. (But I f**cken hate that lower alloy engine plate removal!) I did also ponder whether it would be smart to chop the air filter part of rocker cover off, could make up a plate n silicone to connect it back up after jobs done.. stupid engine design that!

Well done on the turbo change,
Ohsoslow. You'll have to change your username now (to
Notsoslow...?).
Thanks for the further confirmation on the bolts.
And yeah, I don't like pulling that alloy reinforcing plate either - why do you think I'm even entertaining the manifold change through the top?
As I've mentioned in another thread, I'm starting to see EGR errors from the DDE now, although once cleared they seem to have stayed away. I can definitely hear the exhaust whistling out the crack(s) when coasting down a hill with lots of engine braking (2,500rpm plus..) - a high pitched whistle like a penny-whistle.
Looks like I won't get on to this task until later in Sept. - waiting on glow plugs and glow controller now too - finally decided to pull the pin on that job too.
