Mad Max's - Dakar Z3M Coupe S50

[Dave P]

you have been busy I bet the handling is transformed

[Mad Max]

Had a great run out this morning to put the car through it's paces.

At the start of the Evo Triangle:







Then at Ponderosa for a big old fry up:









The car was flawless bar a little bit of pulling to the left under heavy braking, I think that's down to the left front calliper being new and the right one being old. Guess that's a good excuse to get a matching new one for the other side!

Nice shots - good choice of friends too

Spooks - My neighbour actually asked me the other day "Is it only people with fast cars who are allowed to be your friends..?", haha! Common interests and all that.

M1ke - Jonny, the guy with the e36 M3, put that thread up and another on M3 Cutters. Nice comments on the one on 'Cutters thread about Z3MCs.

Here's one last pic I've been sent of the drive:



I had the seal on the engine's constant pressure valve at the weekend, fiddly little job but mine had definitely been weeping for a while:



It was all collecting on the X brace:



The old seal just crumbled off. Here's the CPV:



Whilst that was being sorted it was a good time to replace the very battered undertray. I didn't get a chance to do the front part of it but I'll get around to it. Here's the part I replaced:



And then fitted:



For some reason the new undertray has a cut out on it, when I ordered it I didn't bother getting the cover as I'd thought it was just the diagram that was a little off. I can't work out what the cut out is for though, I originally thought it was for an S54 but the hole is too far back to be for the oil drain.Whilst she was up in the air again I thought I'd get some better pictures of the suspension bits I had fitted.

Rear suspension:



RTABs:



Subframe bushes:



Cheers for reading :)

The later undertray's have a cut out for the sump drain of the S54 so useless for the S50

[Mad Max]

Little mod today, I debaffled the airbox:





No idea if it's made any difference yet as I haven't driven it, but apparently it should.

The on going issue I have is oil leaking, and it's really bugging me! The CPV has stopped leaking now with the new seal which is great, but after going up on ramps again at the weekend it's still coming out - the undertray was soaked! It now looks to be coming from the sump cover on the bottom, so I've had the bolts all nipped up but if that doesn't stop it it's gonna be a £3 o-ring from BMW and £100 of oil from Opie to get it changed, which is very annoying as it was only changed about two months ago.

I've also ordered some Amsoil MTF for the gearbox, after 85k it won't do any harm to have that changed.

Great write up..

Im guessing your not far from me with all the places your visiting ?


If your oil has only done very low miles,why not drop into a clean container and reuse if not contaminated..?

[Mad Max]

Cheers Alpinaman :) Probably not. If you ever fancy a run out in Wales or something then gimmi a shout :)

Well the low mileage oil is still appearing on my garage floor so I've emailed BlueBell BMW to get an oil filter and the sump cover o-ring in ASAP. Hopefully this will be the end of the leaks..! :(
