After I drained all the oil from the box I removed the inner bell housing cover and found the issue that was giving me the leak - a home made gasket ! Although it looks fairly real I believe its just been stencilled out of another one. More engine degreasing I carefully cleaned up the inside of the bell housing and fitted the new gasket I also replaced both oil seals and also the pivot ball and springs. Box back up right I also removed the old rubber oil lines which I intend to just block up now.

Working on the gearbox today and I've managed to give it a good cleanup. I started of with giving the full thing a rinse down with a high pressure hose then I went onto degrease the full thing with engine degreaser. A few rinses later and a good scrub managed to clear 80% of the old crud that was sticking to the box. Also made up a make shift stance with some wood and two scissor jacks

Fitting my gearbox back in this weekend, everyone's more than welcome to give a hand.

and UPS got me with about £20 import tax as it arrived.

both oil seals, gasket in the bell housing, Pivot Ball, springs and the two sensors. Also bought new sump plugs before i destroy the ones i have as they are a bit rounded.

Now that all my components of the gearbox have arrived. Anyone got recommendations on what oil to use ?

Few parts arrived today from concept. Mostly parts to refurbish my gearbox a bit but I'm loving my smooth new fan. Soon to be sprayed purple.

Looks like a very good diy job. Could be a part off another car as it looks moulded.

Check the 10amp fuse for cruise as it shares a fuse with reverse.

Managed to get one from zcentre.

Box is out so going to drain and do everything i can now.

No idea to be honest. Whatever is making the banging noise on high revs i guess.

Looking for a low millage Crank Pulley !

Any idea on costs for a new one ?

ok, So need to find a new or excellent condition oem crank pulley.

So my engine noise is more or less the crank pulley slipping so needs changed. What does everyone recomend ? Stick with the oem and get a new crank damper pulley or get an alluminum pulley from the likes of japseed http://www.japspeed.co.uk/nissan-300zx-lightweight-aluminium-crank-pulley.html I'd prefer not to hear any excess noise and also avoid having to buy new belts too.

Lol, he left it in moderation. Now moved.

Going to replace all the seals while I have the box out. I'm guessing I have to drain the box of fluid before unbolting the back end ? What's the best way to drain it when its off the zed, and will giving the whole thing a power wash do it any harm ?

Also had a good look inside the end of the bell housing and there is an excess of oil in there. So maybe its a good time to replace all the oil seals and gaskets.

Drilling a hole though it did the trick; and a little bit of heat from a burner. I then inserted a screw driver extension and gave it a hit with a mallet.

Tried it, still slides. :(

Had too unfortunately as one of them is broke and wont come off. I'll likely need to take a drill to it and try push a small bar through it to spin it off.

This is a pic of the full of my gearbox and as you can see its a UK box. Its had the oil pipes bypassed but I wanted to get rid of them completely, so can I just find two bolts and plug up the holes ?
