Does anyone know if the E46 M3 suffers from this issue?
Was there a knock or a sign of something being wrong Bing?
Thanks
Ash

Symptoms on page 3 Ash. I'm afraid I have no idea if the M3 suffers the same problem.

I was checking my suspension today and thought I'd have another go at inspecting the driver's side engine mounts. All the visible bolts have looked ok in the past; it's just the couple behind the vanos pressure accumulator which have been tricky to inspect properly.
It was a proper sh!t to get sight of, but very glad I did now!

That rear bolt looks like it’s backed out by a couple of threads

Feeling relieved to have caught it but also a bit silly. The bolt that I was lazy to check might be the one that's the most likely to back out or break, going by the stories in some of these threads.
What's the latest verdict re. replacements? Uprated OEM (10.9) bolts plus Nordlocks?

No reason to change bolts MrPT, nordlocks and thread lock should suffice I would think.MrPT wrote: ↑Sun Jan 06, 2019 9:42 pm Feeling relieved to have caught it but also a bit silly.

They are stretch bolts so I’d like to bin them. Nordlocks feel like a good idea though.john-e89 wrote: ↑Sun Jan 06, 2019 11:00 pmNo reason to change bolts MrPT, nordlocks and thread lock should suffice I would think.MrPT wrote: ↑Sun Jan 06, 2019 9:42 pm Feeling relieved to have caught it but also a bit silly.

Might just remove the pressure accumulator and see how mobile that bolt is before speaking to my indie.

We used nordlock washers on trackside connections on London Underground, they seem to do the job.MrPT wrote: ↑Sun Jan 06, 2019 11:27 pmThey are stretch bolts so I’d like to bin them.

If over-torqued though, they can cause issues with the bonding of the two washer halves becoming unstable/failing.

Ok, you win! Did you replace all the bolts or just the one that backed out?

I remember someone on here had the bolts back out completely leaving the engine resting on the ARB Does anyone know if these would have been replaced when my indie changed my engine mounts to VT mounts?

Ok, so guessing most folk will now look to check their car for this. Can you highlight exactly where to look in the engine bay for this?
