Iím not even sure he has really driven it! He will get to it eventually, and he will be a great judge. The car looked very good to me, when I stopped by last month on a roadtrip.

What should I look into? Vaccum hoses or the valve itself? Is it something I can clean and repair or should I change it straight away?

Unsurprising!

I would check all of the above - there is at least one good thread on this board about this, as well. The part is NLA now, which is why my company is soon releasing a replacement part. The OEM units will wear out eventually, to the point that they are no longer rebuildable.

If you post your findings, diagnosis, and any questions here, we can help!

Start with vacuum system, it will have some sort of leak somewhere I guarantee.



Whether that fixes the valve/flap we will see, but it will fix a lot of other things.


Good to hear we may have an option for replacement!

Last week, some friend was visiting me so I took the opportunity to do a small stress-test on the M5 by driving along in the mountains around Hakone. Another a friend also just bought ŗ 911 Type G and wanted to test it, so we all together.So I gave the M3 for the day to my friend and took the M5!





Funny to see how big is the M5 compared to the E36, while in today world it is barely the size of a modern 3 series

So around Hakone, you have a lot of lovely private roads such as the famous Turnpike or Ashinoko Skyline : roads are great, scenery is nice and law loosely enforced, so it makes a great week-end drive, especially because this day there was very few people on the road.



So I went hard on the M5, as anyway if something is about to break I prefer it to break now so at least I know it

The car is behaving really great on small roads, the suspension is very rigorous, with a nice but firm dampening which is not causing any undesirable movement of the car. Of course the car is swaying a bit like a typical car from this era, but in a tame and very predictable manner, so you can use this body roll to go around easily around the corners. It is however a bit heavy, you can especially feel it downhill when attacking narrow corners : there is some weight pushing you down for sure.
However the car brakes really well, I did not have any issue stopping in any situation. The travel of the brake pedal is however a bit too short for my taste, and I was unable to heel and toe properly...

Once we arrived on the top of the Turnpike I noticed a lot of smoke from below the car with a burning smell... I was quite worried but when I looked below the car I noticed the previous owner wrapped the catalytic converter in some kind of (supposedly) heat resisting fabric and this is consuming itself! I will need to remove that crap ASAP.

Fortunately no big deal as it was actually very cold and snowing outside so no further drama...



We took a coffee and kept driving around. The chassis definitely needs to be revised, as it feel nowhere near as sharp as it should be: all suspension arms, links and bushes need to be changed, as usual on those cars.
The engine is definitely lacking any power below 4500rpm, after however it pulls quite well, even next the the M3 so I guess the issue is really coming from this resonance valve.



We then had fun driving another hour, before having a quick lunch and go back to the highway for home.







The M5 is really much more comfortable than the M3 and easier to live in, I really can't wait to have some long road trip with her!

So that was a good drive, which allowed me to check-up more on the car and I can now plan my maintenance, knowing that there is no emergency as the car is all-in-all running fine:
- All fluids change + filters + spark plugs
- suspensions arms, bushes and links in the front
- Bushes and links in the rear
- Clutch
- Drive shaft U-joint
- And all those vacuum hoses in the engine

This week, the M3 is getting prepared for winter as I don't trust the M5 quite enough yet to serve for long family trips, so I will bring her to my mechanic next week end to kick-off the maintenance loop.

So I went out with the M5 2 weeks ago, barely did 300km with it since I bought it... However I did not have time yet so far to do a proper inspection so I bought it to my mechanic.

So we put the car on the lift and, well, no bad surprises but no good ones either.
The chassis is very clean and totally rust free, as usual in Japan.
However it is a bit wet under the engine and the gearbox, and both rear dampers (SLS) are also leaking, nothing too dramatic yet since power steering fluid doesn't look like being very drained but it will need to be addressed at some point too. So we proceeded with all oils changes (engine, gearbox, and diff): it was very much needed, especially for the gearbox as the oil bolt collected a lot of metal particles, I don't know when was the last time this oil was changed but it was a long while ago... And the owner probably cracked a few gears along the way.
Brakes are also all worn out, pad and rotors need both a change shortly.
Tires are Michelin PS3 from 2016 and still pretty new so those at least won't need to be changed too shortly.

We took the opportunity to have the car lifted to remove the heat fabric around the catalytic converter: it was soaked with oils and that's why it was almost catching fire during my spirited drive in Hakone... Fortunately it was not hiding anything and the whole exhaust line is very clean, except the muffler that shows a bit of rust.

As expected, all suspensions elements and silent-blocs are very well dead and need a change. I used to own an E32 10 years ago and had to change everything also so I am pretty familiar with the pain in the a** that this operation is, so I will collect the parts and bring everything to my mechanic

For the moment, the car feels much smoother after all the oil changes, that was really needed and I am glad it is done.

I already started to collect the breaking parts since those are the most important in order to be able to drive : 4 Dixcel PD rotors (OEM +5%, it says...), Dixcel Extra Speed pads, which are a good compromise for a street+ usage, and Goodridge stainless hoses... I hope to put all this in the car within April since I first have to do some spring maintenance on my M3.

Finally got some time to take care of the M5 lately...
First and foremost, after my little outing in Hakone above, my brake pads were worn to their limit, and the rotors were growing very thin so I changed everything with some new Dixcel parts. At the same time I also changes the brake hoses with stainless hoses from Goodridge.


That being done, I wanted to clean the electricity by removing the aftermarket radio and the radar detector, that were fitted by a previous owner. Both of them were obsolete and incredibly loud, (Japanese like talking devices), in addition the electric connections were very messy and I don't like that. So we removed everything and I chose to put a new Pioneer deck designed to work with a smartphone: https://jpn.pioneer/ja/carrozzeria/c...it/mvh-7500sc/
Honestly I believe this is a very good deck for our old cars: it gives all the connectivity they are lacking, with a very tame design and amber matching illumination, I am super happy with this product! It is also available in EU or in the USA (Pioneer SPH-10BT).


While the car was on the lift, we confirmed that all bushes at the front need replacing as they are worn to a point of non-existence... That is next on the list.
In addition we found out that one of the big hoses connecting the air pump has just corroded and disappeared, need to change that too.
My idling is also a bit high, 1000~1100rpm, and the throttle response a bit sluggish so I am wondering if I don't have other air leaks somewhere, the car runs fine but this needs to be checked too...



Then I went for a thorough cleaning in and out! I am using Ammo NYC product since a few years now and I am really happy with the results, so I spent a day on the M5 as it was needed, especially in the interior.
It is now super clean, however I suspect one of the previous owner to have carried some dog as the leather is scratched pretty well everywhere. Fortunately, nothing unrecoverable, this is going the be the next step. I plan to go through a full leather restoration now, with Colourlock products. The kit is already home and I started to work on the centre console, the result is amazing (I will take pictures when it will be finished)!


I will however need a upholstery shop to have a look at my front door panels since they are delaminating and it will need real work to recover that. Not too high on the priority list right now, but I like to have sorted interiors so will look at it sooner or later.


By the way, the deep cleaning of my floor mats revealed that they are quite worn out, does someone know where I can get a nice quality set?

The car wheel liven up noticeably with fresh bushings up front. I am a big fan of spherical upper (Moosehead) and lower (E31) arms.

Do you have to retain the air pump for legal reasons/inspections etc? Otherwise, now would be a good time to remove it and lose a bit of weight and complication underhood.

We have a kit for that!

I read about E31 arms, they are pricey but that should definitely worth it...

Moosehead bearings seem a bit overkill, do you really feel a difference or is it for the sake of durability only?


I don't know yet what I will do: I want the car properly driveable asap so I am tempted to take some shortcuts with aftermarket parts for the whole front arms and bushes for now and come back to it later when I have a proper garage where I can work myself on the car (hopefully next year).


About air pump delete, the government inspection of the car every 2 years is pretty thorough, so I would not risk it. On the other hand I am not expecting to be still in Japan in 2 years from now... So I will think about it

The lower E31 arms made a more noticeable difference, for sure. But for a sporting driver, the Mooseheads are also worth it. Durability is key in the upper control arm bushing, because any play gives you a nasty shimmy around 55mph or on brake. Mooseheads are serviceable and they hold true longer than any other substitute.

Probably going to get some E31 lower arms as they are the most urgent now, then will plan Mooseheads for the upper ones. Better doing it right at first time I guess...
