Thanks for the input John.

Here in the UK is pretty hard to find high tensile bolts of grade 10-12 that are not black and bolted using Allen keys. I do find it a bit odd, as Allen keys are more likely to round the socket than the normal 6 point hex heads as well.

I'm still investigating where to support the engine before removing the engine mounts. I can put one jack on the transmission side, but to hold the engine I can only see it happening by putting a jack holding the oil sump.
As far as I'm aware, your never supposed to put a jack on the oil sumps because they are not designed to hold weight and tend to bend

Or is it ok in this scenario because the oil sump is only going to hold the engine weight and not the front of the car??

That is the correct answer. The "front" of the engine (Right Hand side) is still held/supported by the Right Hand mount so all you do is put a piece of timber (wood block) in the
jack saddle, line it up under the sump at the gearbox end and gently jack it up until it just touches. You don't want to add any more pressure.

Finish removing the gearbox and replace the clutch.

When you are putting the gearbox back in, you might need to raise or lower the gearbox end of the engine to help line up the shaft into the pilot bush/bearing.

Do so in small increments so you don't damage the oil sump.

Shouldn't do if they're 12.9 HT bolts, steel will probably be harder than most Allen keys :lol: .
Always a good idea to have a decent hex bit too ...HEX-BIT-SOCKET-SET (These are 3/8" & 1/4" drive but adapters are available). Having the right tools saves a lot of time and damage ... and keeps the skin on your knuckles.

Phill.
i think you will be pleased to see i got one of these.

this is actually the same socket allen keys i have used that rounded the slots in the bolts on the car. so. its possible the bolts on the car are not 10-12 grade HT steel, or maybe the 25 years of use got the best of them... i dont know.

I have made som progress again.
both engine mounts are free now and the engine does move up and down with the jack, (although i didnt make it move more than a cm so far.

Im now looking for the flywheel cover nuts to take them off, and hopefully end up getting things ready for the clutch change still today

Flywheel cover is out.

Next step is to lower the transmission side of the engine and undo 4 bolts that connect the transmission to the engine.

I can see 2 of them. No idea where the other 2 are

Will upload a Picture of the 2 I see soon

im having some dificulty uploading pictures, so only managed to get 1 working.

these bolts are in the front of the engine, the bar in the background going down is the "left hand stay" that attaches to the subframe.

I have managed to finish the job now. was quite a struggle to find the other 3 bolts aroudn the transmission.

after that taking the tranmission out was not a problem at all, changing the clutch bearing was the easiest task of the whole job, and swapping the clutch itself was not much of a problem.

refitting the transmission was a whole pain on itself.

funny "little" event that happened when reasembly everything was when putting back the clutch cable braket... one of the 10mm bolts fell off my hand..... into the speedo cable entry on the transmission. it took me 2 hours of fishing with a stick with a magnet at the end to get the bolt out.

apart from that the rest of the re-assembly process was pretty smooth, with brand new bolts being fitted in both sides for the suspension upper joint area. i put back all shims as they were before, (i had 6 instead of 8 in both sides)

took plenty of pictures which i will be adding to the post whever i have time.

as part of the job, i also swapped the oil filter with a new one, new oil (obviousl) and new denso spark plugs. and topped up the transmission oil as well.

after charging the battery, the car started no problem. I havent actually tried the clutch and gears yet tho, that is a job probably for this sunday...
