Do you have vvt? Or is it not used on the formula engines? The exhaust cam journals wear out and you lose oil pressure there. You can run an oil restrictor in the block to help improve oil pressure as well.

Tell him he needs to man up and register on here then lol

How much more convincing does he need?! If he’s on here, tag him in here lol

Well folks, the diff works and from what I’ve seen, it’s on a par with the quaife. Only difference is that it’s cheaper!

Update on this! My mate has been driving the clio like a hooligan with the blackline diff installed, and it’s all positive noises coming out of his mouth. On track tomorrow. 👍🏻👍🏻

Change the oil to redline mtl and re bleed the clutch.

I’ve got a 129 (same as a 130, just has a speedo drive) that I can build up? It will be fully rebuilt and reliable. Pm me if you’re interested @HarleyV123 👍🏻

You’ll probably find that the diff is worn internally - namely the planet gears have worn into the casing. It’s boot unusual to see tbh, but it means you’d need a new diff regardless. I know the exact noise you’re describing and I can confirm the noise when up in the air is normal. As is the...

No worries 👍🏻 Well you need one with a speedo drive.

I’ve got a 089/129 gearbox that I can rebuild and supply if you’re still looking for one?

Yep. Got one I can rebuild @Stevendjk

Mk2 crownwheel needs to be machined to suit the blackline - the same as the quaife. The mk3 crownwheel is bolted on. Couldn’t say if the diff fits in a Meg box though I’m afraid.

Good to know mate! They work well in the mk3 clios too.

Lol

Did a trial run with the diff fitting this evening. Fitting was fine and no preload adjustment required! Heated the crownwheel and fired it on the diff. Only negative is the thread for the nut isn’t as nicely cut as you’d get on a quaife, but, the nut tightens down to torque spec, so all good!

For anyone else interested in the blackline diff, I now have a blackline diff in my possession to fit in a mates gearbox. It’s nigh on identical to the quaife, and I will be fitting it in the box tomorrow evening for a dry run - just to see what the fit is like. If it’s all good, I’ll then fit...

Right ok fair enough. Well there’s a strong possibility that there’s an unhappy bearing in there then if you can hear a droning noise. Unfortunately these cars were built in the knowledge that they were going to be abused. But the diff will make noises when it’s jacked up.

They all make a noise when they’re jacked up, so I’d advise that you drop the oil out of it and make sure the oil has no debris/particles in it. The gearbox code you have is a jc5 089. You ideally want another one of those, or a 129 - this gearbox has a speedo drive as does your 089. I can’t...

Tag didn’t work for some reason 🤷🏻‍♂️

@Touring_Rob do you want all the Renault part numbers? I have the correct ones for all the bearings in a 130 box. Or are you only after specific ones?

The bell housing of a 197/200 box is huge in comparison mate. Only real option is to find a 6 speed TL4 from a dci as they have a smaller bell housing from memory, then fit the 197/200 gear kit inside the box. Next problem to overcome is the crank sensor position as it’s different on the TL4...

None.

You’re welcome mate 👍🏻

Yeah you can do it. I’ve done loads. You need to drill the hole straight and then transfer the speedo drive bits over from the 129.

Yep that’ll work fine with a 089 👍🏻

Email this guy: allan@bridgecraftmotorsport.co.uk Tell him I sent you and he should be able to help you out mate.

You need the upper casing half that’s got the twin taper bearing setup. The later boxes had a taper bearing and a parallel roller bearing, so you can’t use them as they’re not compatible. If in doubt, upload images of the casings you’re offered and I’ll tell you if they’re any good or not.

I can do mate yeah, but it might be worth checking the cost of shipping first buddy. The Brexit morons have made life seriously hard work

Well that’s no bother to sort mate either way. I’m Lichfield Staffordshire, so midlands basically. If you can box it up, you can get it delivered for about £40 using the ups option on interparcel. Just have to put it down as car parts! Put it down as a gearbox and they’ll refuse to take it lol
