...Had to order an M20x1.5x50mm bolt which no one seems to keep...

Part of the Coventry Fasteners Group is where I got mine. Very common bolt. $3.00

Yours is the post I got the info from, thank you kindly.

I ended up ordering it from bolt.com.au at 6x that price unfortunately.

Hey Hylife, can you have a look at the water jacket cut-outs in the copper gasket and tell me what you think? Should they all be cut out, or just the two that are?

They are a pretty good copy and appear in fine condition to be reusable. I would however finger smear a very thin coat of Permatex Grey on the mating surfaces before bolting the head and sleeve down.

The main water flow is meant to completely circulate around the water galleries so there is normally only one inlet and one outlet (those two main slots).
To reduce an abnormal temperature/pressure situation, you will notice that the OEM gasket has three additional small holes which allows a small amount of coolant to flow, but those extra 3 holes are really there to prevent you blowing a head gasket in the event of overheated coolant building up too much pressure.



In your situation, water prerssure is not the concern, it is cylinder pressure caused by the turbo forcing in more air than was anticipated in the original design. That is why you need the copper gasket.

If my memory serves me correctly the small hole next to the head/sleeve bolt hole is for an oil gallery which IS open on your gasket. :)

No surprises





One of the bits in here looks like a piece of clutch plate.



I wonder if some stray clutch was the cause of the 2nd gear failure.

Seems it's scored a bearing as well. Tested it and it feels ratchety and ..not smooth.

It'll have little bits of metal in it which may or may not have buggered a ball or two.
Press it out of the case and if after a good wash it still feels notchy, replace it.

An old trick for removing bearings was to heat the case in the oven to 120oC (expansion) and to use a spray can of Freezer to rapidly cool just the bearing (contraction) and then tap the bearing out using the correct sized bush drive adaptor.
For pressing in the replacement, freeze the bearing in the kitchen freezer and heat the case.
