Breaking Bank - E39 M5 Content

Bonus beneficiary believes buying broken BMW brings beneficent lifestyle benefits.

It seems like there has been a deluge of E39 related posts lately, so now that my torture of the "B" key has grabbed your attention allow me to introduce my latest bad decision.
After telling myself that I needed an E92 M3 because "one must own a v8 at least once in one's lifetime" I soon found myself thinking that BMW M had really short-changed me on displacement. The S65 was meant to be an upgrade from the S54, but something about only 25% more engine capacity for 33% more cylinders just doesn't feel right. Thus started the search for something more in keeping with expectations. A few years, and a house purchase, later I was introduced to a gentleman in September 2023 who was looking for a good home for a family heirloom M5. When I first viewed the car I wasn't certain I needed a project in my life and the owner wasn't certain he was ready to let go of fond memories. Fast forward to February 2024 and I got a call from the owner to tell me that he'd decided to sell. The timing was good, see bonus beneficiary alliteration above, and I was in a position to make an offer. The owner did a lot of deliberating and I did some negotiating before we shook hands. Funds were moved, a work afternoon was bunked, and just like that I was sat looking at a white facelift M5 in my driveway.







Well, technically not my driveway. While the car was loved, it certainly wasn't maintained beyond semi-regular oil changes. This almost certainly meant that I was going to need to do some major surgery and I'm not sure my neighbours would appreciate seeing another BMW leaking oil onto the driveway, let alone one in pieces, so the car was taken straight to my father's workshop.



With north of 250 000km on the odometer it was a given that the suspension and engine would need a refresh, but neither the mileage nor the required repairs put me off the car. She came with a fat stack of invoices for maintenance and repairs, a straight chasis, honest paintwork and the interior still smelled like I remember them smelling when they were new. Couple that with only 2 previous owners, a distinct lack of alternatives for sale, and a bargain price and I think I made a good decision.

After a thorough inspection the major items needing attention were:
- Rough idle coupled with a vanos and cam timing error code
- Cracked windshield
- Knackered suspension and I mean knackered. Jacking the car up and lowering it too quickly resulted in the suspension bottoming out. I knew that the ride was less than perfect after the test drive, but at this point it was safe to assume that the car was riding on springs only
- The rear window blind is broken and needs replacing
- Driver's side doorlock is broken, getting in and out of the car involves climbing over the centre console to get to the passenger door. I'm still young and fit, but I think vehicular parkour isn't about to take off as a new sport so this will need to be fixed
- Tyres are balder than Vin Diesel and the rims are in a similar condition to Paul Walker
- There is enough oil and gunk in the engine bay to trigger an aneurism in Greta Thunberg so it's likely that power steering hoses are going to need to be replaced
- The car has been sitting and the battery has a few dead cells

More things were bound to pop up as I got stuck in but the initial project plan was as follows:
- Big end bearing refresh
- Timing chain guiderail replacement
- Vanos overhaul
- Power steering hose replacement
- Full front and rear suspension refresh
- Replace engine oil, diff and gearbox oil, brake fluid and all coolant
- Driver's side door lock replacement
- Source and replace rear window blind
- Rim refurbishment along with new rubber
- New battery

The local BMW dealership was most pleased to receive my parts order...

***EDIT***
It's been so long since I did my initial inspection that I forgot another important fault. The dreaded trifecta lights are illuminated on the cluster. I'm hoping that this is just the result of the dead battery or a faulty sensor. Time will tell, but safe to say that the worst case is a rather expensive exercise in replacing the DSC module.

Very nice, enjoy it well.

My rear wheel bearing got my 3 series throwing the trifecta, maybe check on them as well with over 250000 km im sure they are done.

Congrats on an awesome project! Looks like a very good starting point, these engines can easily do double that mileage.

I ordered a complete Lemforder suspension rebuild kit (OEM) from ECS, I paid around 25k landed (after some evasive maneuvers) - BMW wanted double that when they quoted me. Imcomex also stocks B8 Bilsteins for this car, but I think they just sold their last set but should get stock in July again.
 
Congrats! E39s always remind me of my father and the E36 he sold instead of giving it to me :ROFLMAO:

That being said, the descriptions of the issues are gold!

+1 for comedic value

And good luck for an awesome project!

Thanks for the kind words everyone and sorry for keeping you in suspense (I think I've slipped from the realms of being a tease to just plain rude). A lot has been done on the car so far, but I've not had the time to post all of it up. Keep your eyes peeled for another update this weekend!

Thanks for the tip, I had only considered the ABS sensors and the DSC unit itself. Small spoiler alert, it wasn't the ABS sensors.

Sounds like you're going to be the local YouTube guy: M539 restorations.

How's some pics of that green e28 in the background?
I have a soft spot for the e28...
Some days I wish I could leave my desk job and start a YouTube channel, but I quickly realise I'm not tall enough for Hollywood.
Unfortunately the e28 in the background is a parts car and in a sorry state after having served its purpose so I wouldn't call it photoworthy. Here's a better looking substitute to ease the disappointment:

Thanks Benji, I investigated the aftermarket route and wasn't au fait with the option of evasive maneuvers so the cost after import taxes and shipping landed up being so close to the OEM price that I decided to go that route. I followed a similar path on the shocks though.

You have not learned from your fathers clients mistakes. Cheap hookers, cheap booze and old BM's all great times with horrific consequences. Congrats enjoy it when it is running.

Sorry folks, life happened and some basic household maintenance in my home office meant I didn't have access to my PC for longer than I expected. On to the promised update!

The first sign that this was going to be a labour of love was the protracted waiting times for parts to be shipped. I had planned to start working on the car before winter arrived, but parts on back-order meant that I was about to learn about the effect of cold concrete floors on a spine molded by office furniture. Fortunately I wouldn't be sharing this burden alone, a dear friend wanted to atone for the sin of owning a Focus RS and offered to lend a helping hand. Thus it was that one early morning (9:30am), as the frost was just beginning to melt off the grass (or maybe it was wet because the garden service had watered it) we cracked open the boot of the M5 to disconnect the battery.

This was an important first step as it allowed me to enjoy my take-away cappuccino while impressing upon my friend the importance of an understanding SO before filling the boot of an ///M car with so many parts. Next we decided to see if the bonnet shocks had stood the test of time.

Those of you with sharp eyes will not need me to explain that they had not. For the rest of you, note the broomstick on the right side of the engine bay. Since I still had my coffee in hand at this point I decided it would be best to test my mate's wrenching skills and I instructed him to remove the viscous fan.
20240518-100410.jpg


He did ok with taking the air filter boxes and MAFs off, but not even marriage prepared him for the patience required to liberate the viscous fan using only a spanner and hammer. I've been told there's a special tool to help with this process and I've always shrugged off this advice as lacking an element of character building. Coffee finished and lessons in stoic perseverance delivered, I reached for the ratchet and 8mm socket to assist in removing the cover for the plenum...

... to reveal the beautiful mess of intake trumpets underneath. Just take a moment to appreciate the design, a work of art in my opinion.

20240518-103421.jpg


Fortunately at the time we paused to appreciate our progress as the second sign of a labour of love was about to be visited on me.
We split our efforts across each cylinder bank, I took the driver's side and my friend took the passenger's side to remove the trumpets. Shortly into the wrenching I ran into difficulties. The cylinder 2 trumpet nuts were not coming off easily and the socket was struggling to properly seat itself over the nut. The cause of this turned out to be that the rubber gasket which seats the plenum around the trumpets was incorrectly installed and has flapped itself over the lip of the trumpet thereby trapping it and the nut holding it on.

20240518-110351.jpg


Curses were cast at whichever hurried sod had last installed the intake and the trumpet was freed. Here you can see the gaskets on each bank which sit between the throttle bodies and the plenum to create an air -and intake trumpet- tight seal.

At this point we'd gotten into a good groove and parts were coming off quickly. Say goodbye to the valve covers, the coil packs and the associated wiring harness.

Right now Postimage isn't playing ball with the rest of my photos, so I'm going to end this one prematurely. In the next update I'll continue with the teardown. The immediate goal here is to get to the timing chain to replace the guiderails.
