Not much to report tonight, pretty much got everything sorted for removing the head tomorrow. Got the exhaust disconnected from the extractors from under here:

And above here:
That was probably the nicest pair of nuts to undo today, even though there was only enough space for the ratchet to move 2 or 3 clicks at a time.

Got the bolts holding down the head off like this:

I only got to this state after removing a 11/16" nut holding down an earth strap. Unfortunately I didn't realize there even was a 11/16" spanner in the house, let alone that was the size for a good 20 minutes.

Also the manual says that the bolts holding the head on are 1/2" or 13mm. I tried them with a 13mm spanner and started to strip the 12 point head so I decided to buy a slightly smaller 1/2" deep socket. The fun thing about the 1/2" deep sockets sold at Bunnings is the hole in the middle is tapered, with the smaller end towards the bolt. This meant that the brand new tool I'd just driven across town and bought was actually not going to work. So after messing with sandpaper and getting nowhere a round file was found that was used to enlarge the narrow end of the taper just enough to be able to be pushed over the studs. However that is still not the end of the story. Because after loosening some of the bolts the socket would get stuck on the stud. The solution involved a hammer, a 1/4" drive socket extension and a sharp corner in the engine bay. By putting the extension down the middle of the socket so it was resting on the end of the stud, putting a sharp corner in between the socket and the stud I was able to tap them out. Thankfully.

By this time tomorrow I should have the engine in halves and some very interesting photos to show just how bad this engine has become.
