MG4 Reduction Gearbox Oil Leak

[bowfer]

Mine is getting breather fitted 29/11, which is a pain but I need a loan car.
That will be 24 days after I collected it, and I’ll be keeping a close eye.
Any sign of further leaks and I’m rejecting, had enough of this and the rumbling/vibration which I’ve had zero feedback from MG on.

After lots of angry emails, our is getting fitted in the morning!

I’m still waiting. My dealer said MG had told dealer aftermarket salesperson one thing about part availability and posting/couriering, then changed the ETA when it didn’t arrive when expected. Go MG!

My ordered Breather Pipe part arrived at my dealer (for my yet-to-be-collected new Trophy) today.

That's great to hear
All should be good now then.
Just the software issues to resolve for everyone

Just had the new breather fitted in our car and had an interesting chat with the service manager. He said that the top of the breather was dry and the oil was coming out of the thread of the breather tube, he also noted lack of any thread sealing material. He thought that some thread seal would have solved the issue on our car.

Hi all just had my weekly check on the oil leak poll, total votes today stands at
70 that’s 8 more than last week.

33 have not seen any oil leaks up 1 from last week

6 had a leak from being over filled same as last week.

31 have a leak but don’t know where it’s from that’s UP 7 from last week

So yesterday I check my wife’s MG4 SE SR again she has now done 550 miles mostly short journeys But two of 60 miles or so but no sign of any leaks as yet.

Yes I jacked the car up and laid underneath it you can see the pipe and just about get your phone up near it to take a picture. Cheers Baz

Did you take the undertray off or were you able to get in at the wheel to take the picture?

That would depend on how big the bulge was in the undertray

@Baz Thank you for the comprehensive write up and the picture.
@stevemc Interesting theory about the leak around the thread.
I have to call that modification what it is - a true bodge worthy of BL in the 1970s. I love the attention to detail - two right angled bends, a stamped bracket with Terry clip to hold the assembly, the use of aluminium braid covered tube for no purpose other than look tarty (or because they had some lying around), and the reuse of the original breather. Fantastic!
It's good that MG avoided the temptation to go vertically up between the HV cables.
Still, if it works I'll not be complaining. In fact, I may join @4ND in buying one as a talking point.

Has the old saying goes— they don’t build them like they use to
Maybe MG are trying their very best to prove that wrong LOL

Thanks Baz can I ask which side did you jack up you don’t say I’m trying to find where this breather is, I have been under the car but can’t see anything only a big bulge in the tray so if I can find where to look I can keep an eye on it.

No need to take undertray off you can get your hand up between it and the subframe just a pig finding a place for a torch

Nearside but will jackup both sides next time to make it easier trust me if it leaks you will se it. To be fair to come up with a bodge sorry solution and design/manufacture/and supply in 2 weeks ain't bad. I would like to see other manufacturers do better. Been in the motor trade over 40 +years so seen a lot worse. Baz
