taxed, tested and covered 90 miles no problem ,

Awesome, give us the full low down on how the 3 litre feels over a 2.8 then

Post Mon May 25, 2015 5:25 pm

Looks good

and after all the work a new MOT is a great feeling

Seeing yours makes me want to keep my RG wheels, but I've just bought 2 new 15" tyres for MOT

Id also be interested to hear the difference of the 3.0 over the 2.8

Post Mon May 25, 2015 6:23 pm

1st gear just wants to spin with hardly any effort and a bit embarrasing when i don't want to do it lol ...... 3rd gear pull is great i don't need to thrash the bores out of it now. The extra torque is just what the m52 needed , i found myself kicking the clutch to get the revs up into vanos quicker when it was a 2.8 .

95 mph at 3k revs

Looking good Mick

yeah it's great , i kept going for 6th gear when it was a 5 speed

Post Sat May 30, 2015 11:46 am

all my gears are fine but when on tick over the box is noisey unless i hold the clutch down ...pretty p1ssed off about this but not gonna let it spoil the moment as it works ok apart from this .

looks like i've been tucked up again, that's every gearbox i've had in the car now

anyhoo i've bought some better g/box gloup that might shut the box up a bit and my engine oil and filter turned up ...

Might be the release bearing, Mick.

brand new clutch and bearing mate .

Post Sat May 30, 2015 11:23 pm

Could be wrong Mick but think there's 3 different types of oil for the 6 speeders depending on what colour sticker your box has known it, think there was a green, orange and yellow sticker. Don't know why there would be a difference but sure when I looked into it there was.

How about the spigot bearing? Definitely the right size?

Good point my standard IS one was the wrong size for the 6speeder had to get another off a beating company.

Post Sun May 31, 2015 1:15 pm

is it flywheel chatter? or maybe the lay shaft bearing is failing?

Post Mon Jun 01, 2015 8:24 am

Mick, my 6 speed is the same, with the clutch up and in neutral it does clatter a bit.

I was worried about it , did a load of googling and it seemed a common thing.

It's not got any worse a year later on.

I used Royal Purple syncromax oil for your info.

Post Mon Jun 01, 2015 8:52 am

Its a Getrag thing

Post Fri Jul 03, 2015 9:23 am

will any other 6- speed boxes fit i.e e46 one ??

i've got a zf 5-speed here but need a prop coz i cut mine up to fit the 6-speed

Post Sat Jul 04, 2015 10:07 am

managed to locate a prop £75 delivered ... my eyes have been pulled out again

on a brighter note every coont else wants £99.99 + courier .

i'm not giving up on the 6-speed just yet ..... reconditioned might be an option .

Post Sat Jul 04, 2015 6:15 pm

Id get it rebuilt Mick, will probably be cheaper than buying another worn box

What could possibly go wrong

Post Sun Jul 05, 2015 7:50 pm

it's already gone wrong .... a gearbox repair isn't going to be cheap and i'll probably have to pull the engine out to remove the box .

Post Sun Jul 05, 2015 7:55 pm

My 6 speed box in my e36 has been noisey on idle for 40,000 miles like every other getrag box. Sound no worse than any M20 box i've had. I'd not worry too much

Post Sun Jul 05, 2015 9:04 pm

The rattle at idle is the lay gear having a bit too much play/backlash. I wouldn't worry about it. If it bothers you that much drain it and bang some EP90 in there - not even remotely recommended by the manufacturer but it'll quieten it down. I did this on a five speed E46 unit and it's still going now and the gearshift is fine - a bit baulky in very cold weather.

Was a handful of sawdust that did the trick in my day.
