2008 Z4M Roadster

[Katanator]

Being on holiday is not good for opening or keeping a space open in the garage.


With a 6pot BMW petrol in manual on the bucket list going through options a lot of the roads kept coming back to a Z4M. S54 and s85 seems like a decent combo and some of the best BMW had to offer.


Hard to find a well taken care of sample at a decent price this one on the forum had my interest.

Z4M Engine Essentials - 1

Wow well done on keeping the Z fresh. Looks fantastic. I like the CSL wheels :thumbs:

www.bmwfanatics.co.za

Currently just below 200k km on the clock.


Previous owner attended to most critical maintenance items, bearings, clearances, diff, clutch, shocks, gearbox oil so my work will mostly be cosmetic. Mostly done by forum members Clint and PeterAEW. All records kept


First off a front bumper spray, dent removal and rim refurbishment. I would like to refit the OEM rims once these tyres have tun their course.


Some plastic items to be ordered, the typical parts ive seen worn on every Z4M.

1. Windscreen wiper cowl

2. Windscreen rubber trim

3. Safety belt guide

4. Floormats


On the mechanical side I plan below

1. Fuel filter change

2. Upgrade exhaust cam hub with 5150 motorsport hub

3. Upgrade vanos hub bolts

4. Replace vanos seals

5. Valve cover gasket seems to be sweating/leaking too much for my liking.

6. Rear main seal leak

7. Leaky power steering


Any other suggestions to bullet proof this thing mechanically. Should I consider water pump and injectors?

Congrats! She seems to have good history on this forum, hope she treats you well, cant wait to see this on the skid pan

Does it still have the aftermarket exhaust on it?

 

[Katanator]

Exhaust is back to stock.

I will for now plan to get everything back to as stock as possible. Part from the CSL reps and a gloss black front grille.

Only reasonable mod for now will be the upgraded exhaust cam hub.

@Peter@AEW @Clint@MMS AUTO, the invoicing of these guys are an enthusiast dream, super detailed with comments etc. Very impressive.

Was the exhaust not RPI? I'd say keep it unless it's too droney. Also maybe CSL airbox? These are such good drivers cars... Enjoy it!

Yep it is his.

Seems like he took it off some time ago.

Would like a CSL airbox. Ideally if someone has one to sell secondhand. Dont know if I want to fork out R40k for a new one.

 

[Clint@MMS AUTO]

Good job, Glad this one made its way to you. Its a really fun car and i'm sure you will enjoy the experience.

Lots of effort and money went into its maintenance over the years under Pete's ownership and i'm sure he will miss it dearly.

Enjoy it.

In for rims and front bumper today.

Will add some fresh wheel badges en M stickers.

 

[Katanator]

Some other usual gremlins from an 18 year old car. Parts on order.

Mostly small underbody panels, rear bump stops and exhaust hanger.

 

[Katanator]

Other than that busy with my usual spring clean and interior treatments.

With a new accomplice sharing the joy.

Some goodies on order.

Ill be replacing the exhaust cam hub with the 5150 hub. It seems like a hotly debated topic to do the hub only or oil pump disc as well. I will see how the disc measures when its open. The 5150 hub has got larger tabs to reduce freeplay and fatigue on the hub tabs from slamming against the oil pump disc holes. Beisan suggests to replace both but they use standard size tabs and smaller holes on the pump disc whilst 5150 uses larger tabs and standard holes. Seems like Beisan chose a more nuanced path but then they get to sell two items instead of one. DrVanos suggests to replace both as well like Beisan whilst VAC motorsport offers the same solution as 5150. All of them use harder material and thicker tabs so I figure if the stock hub could last 200 000km any of the above should at least outlast that.

Previous owner also included a valve shim kit so will measure those whilst in there.

Also opted for the ECS viton vanos and vanos seal plate seals to save on shipping with one order.

Along with this I will also get a set of the updated VANOS hub mounting bolts, upper chain tensioner rail and VANOS filter/strainer from the dealers. Prices at local dealers seems cheaper in general than importing items available through them.
