Hello folks Im new here having wanted an e34 for a few years but only just ticked the box. I’ve just bought a 1991 525iA (M50) with 70k miles from Cosford Hall Classics. Not yet collected whilst I wait for my 2006 XJR to sell but enjoying reading the various threads on here in the mean time. I was weighing up an e30 but cost and relative condition put me off; I do really like them but I don’t have funds for a rolling restoration so hoping the e34 will be relatively pain free. Interior is excellent, exterior has a fair few badly touched up chips - overall it looks straight. Anyway, a few pics for those that didn’t see the eBay ad. I look forward to learning more and hopefully contribute in some way.

Oil and filter changed today, 700 miles short of the 10k I was aiming for. Thought I'd do it today while it was looking like staying dry. Vacuumed out most of the oil before removing the sump plug to drain out the dreggs.

This was the one I spotted last month! What is it with these scam S62 engines!

N47 is a good engine...with a new chain and corresponding gaskets, bolts etc and a new/refurbished HPFP. I've had all of that done and it's running very well, had a remap since and it drives great

N47 timing chain is ticking time bomb, if not been replaced. 120-150k miles is usual lifespan when people replace them. To make things harder, timing chain is at the back of engine, so to replace you need either to take out engine or remove transmission for access. M47 in my opinion is that same as m57 just with 2 cylinders less. Removing swirls flaps is easy to do. I don't know if they are found just on automatic transmission model like with E39 or are they on all models, but it's easy enough to delete them. N47 have them as well, just upgraded design, so they are not as fragile as on early M47/57 diesel engines.

I reported the seller to Ebay and since then I've two emails from Ebay telling me the account had been compromised... Although at one point I did invoke a reaction from the scammer when I intimated that he was a bit simple and then led him to reply with a load of abuse and telling me to come and visit with £8k... LOL I did reply that I did welcome his offer however as he failed to give me an address with which to go an visit with my £8k he might actually be the stupid one in the dialogue... I then highlighted that a S62 is a V8 and the one he was selling was missing two cylinders as he'd advertised it as a V6....

Caps are also way cheaper for the e34 compared to the e30 ones. And buy from bmw...often cheaper for than ebay and the likes.

DDD (if I can call you that...), I did look on Google/YouTube - that's what set me out on this quest! And the results are very seductive. We're about to embark on another, totally unrelated, project with the help of a skilled fabricator, so I'm going to ask if he can do this too. We can put up with the mpg, only because we hardly go anywhere not in our work vehicle (a Panda 4x4!), so when we do, it doesn't seem a burden. A long commute or similar would bring a swift end to V8 joy.

All sorted now thank you. Know which one I need. Probably just a passenger side front now

I've done a few engine mounts or subframe lowerings just by using the front lifting eye, it's how BMW do it as I followed the instructions in ista. It doesn't tilt as your using the highest point. Sent from my SM-G920F using Tapatalk

That looks great! Welcome

They will not go missing, unlike the E30 one's, they are a much better design

Here you go. The scuttle plastic had to come off and the intake manifold otherwise the chain would have pressed into both of them and possibly cracked something.

There is a hole in the bell housing just above the starter motor that is for lifting the engine. You can support the engine with a beam but you need to be careful because the front wings are aluminium and without spreading the load a bit you can press into the inner wings. I'll see if I can dig out some photos, I lifted my engine with a home made wood support. It was unbelievably solid!!!

Thanks - I figured it out - was at my wits end, having worked all week on the car and needing it to go & see my kids at the weekend.. The car has done 166k miles - have had the usual carbon build up problems. Will do a mega post soon with the whole timeline - I read the 'so you bought an E60' guide, but there's lots of extra info that would be helpful.. What happened was - I knew there was a leak of some kind around the injectors (due to the persistent moisture). So I removed the fuel return pipe from just that front injector to check the torque on the injector bolt. It was 100% fine, so I replaced the fuel return line on just that injector (hadn't disturbed the others). In doing so, I had dripped a small amount of diesel into the dip/valley around the injector. When I started the engine from cold (proper cold - hadn't been run all week), the bubbling effect that you can see on the video happened. Having done a lot of thinking and research, I believe that there is carbon build up underneath the injectors and probably the injectors themselves need an internal clean; see this excellent video: https://youtu.be/l2b76TWncFo I'm so hacked off with the issues with the car that I'm now throwing the kitchen sink at it - have bought the injector test kit & the ultrasonic cleaner that he has in the video. Am doing it Wednesday and hoping to film - will post results back here..

No i don,t eat tacos but yes i did take 3 seperate breaks during the night,one after 4.15hrs driving and another after tipping Telford so i could then legally drive on to Enfield where i had another tacho break waiting for the customer to open.

+1 The cable will likely have stretched a we bit after 30 odd years of use, especially if it has not been lubricated. Stay safe and best regards, Mick

Get a new cable Ian. It will make a world of difference!
