Apparently, there wasn't any other major damage as they were able to repair the spring. I didn't have a warranty, so i paid out of pocket, about $3,100 to replace the one spring. Honestly, I've been thinking about selling the car ever since, but I have put on 850 miles since the repair. Haven't been driving hard, but i've taken it up to 7-8k rpms and all seems... fine. I used to go on canyon runs often and I haven't done one since. Just nervous I guess, which take out all the fun of owning one of these cars. The service advisor said that I should do an oil change at 1K miles post-repair and every 2-3K miles thereafter... No rattling. I was going uphill at the time, so I was in 3rd gear for about 2 minutes or so... but it was gentle driving. Seems like the valve spring gave out on the spot.

I know of another M3 that also had a valve spring failure around 70k.
Is there anything we can do to prevent these? More oil changes? |

If you're up for it, I'd be interested to know what warranty you had and the cost for something like that. I may keep a warranty on the car or sell, not sure...

I have the same issue, driving her lightly, then hit limp mode. Car was shaking, my vorsteiner titanium exhaust sounded like crap. Threw code p0306. Towed the car to a shop, replaced all ignition coils and plugs still misfiring cylinder 6. Ran compression test and bank 6 has 0 COMPRESSION. I'm now informed that it could be my Valve spring. I got quoted labor/ parts to replace the issue of 5500. Requires around 30 hrs/labor. I'm about to give them the Okay to open the head, send it to a machine shop and replace the all 4 springs on driver side. Are you/ did you have the same issue as me? I wanna know forsure before I drop more money. Already 4k in the hole and don't wanna drop another 5500. |

Well, OK! I've got a set of Supertech valve springs on my watchlist. I guess this will be a good warmup before attacking the connecting rod bearings...., I've changed valve springs and retainers on several overhead valve and overhead cam engines without pulling the heads, so I understand the general procedure. newtis.info procedure for valve spring changes start with the heads off the engine, but I'm sure the predecessor procedures will show how to remove the timing gear and cams without breaking them. Anyone know of a link to a DIY?

Why would lack of driving affect springs?
Over-revving is more of a culprit

Visualizing broken valve spring
I am pretty sure I have a broken valve spring, as I suddenly lost all compression in Cylinder #3 and of course started shaking and went into limp mode. I put a borescope in the cylinder through the spark plug hole, and as you can see in the picture below if you look carefully, one of the intake valves (I believe) is not closed while the other is. The picture is out of focus because I couldn't get a goos shot at TDC. My question is, if I take off the valve cover, can you see the springs clearly or does the cam shaft need to come off to see if the spring is broken. The latter would require retiming the engine which I wouldn't be able to do.

Yes, I think the cams have to come out to get a proper view of the valve springs.

No, springs look like they're still in but one exhaust side retainer is missing the keepers. Looks like that one is where the failure happened.
