Now THAT is sarcasm!
another one in Italy too.
This must be BMW's version of the multi-valve/variable valve engine. As your engine ages, it slowly converts from a 4-valve to 2 valve engine, so you dont notice the decrease in power, but you're happy because the gas mileage increases. Plus, over time, you get the added benefit of less moving parts..which is always a good thing!
Am I the Italian user with soft cams!
My bike has only 2000 km. I heard the noise of the valves increase and I did check it immediately by opening the cover.
My cams consumption is micrometric comparing those in the previous photo.
All components to be replaced under warranty.
No wasn't Rotella.
I agree, hope the filter and magnet caught the metal. I guess time will tell where the metal went for sure. They did tell this would have been a $3000 repair
if it wasn't under warranty. I can't imagine what open heart surgery would cost on this thing. Pretty nauseating to think about honestly.
Glad you caught it earlier than I did.
I'm the OP who posted the video. I emailed the video to the dealer. They watched it and said that the noise was normal. I felt better, but not convinced. This past Saturday I took the bike into the dealer for an unrelated issue (AVC error) and I asked if they could check the bike for the noise again. Well, my bike is still in the shop, awaiting approval from BMW for new cams. Moral of the story: A video or recording is almost worthless. If something sounds off, take the bike in.
I'll post more details when I find out more. Good thing my GS is still under warranty. It actually expires in a couple of months. I'll be extending it.
I hear that...
I posted earlier in this thread in response to your concern.. agreed with you that your engine sounded... well... not good
Your's is a 2014?
Thought the "soft cam" issue was limited to a small batch of 2016s...
Maybe it's not a soft cam issue.. but some sort of decompression device rejigger..
see post # 9 in this thread
There's a senior fellow over in the FM that just sold his 2016 GS w- 3,800 miles...
In his ad, he wrote that all four cams have been replaced... didn't say why
Keep us posted
What began as a ticking or tapping noise (possible valve adjustment needed) ended up being a worn right-side intake cam that was indeed causing the right-side intake valves to be loose. The dealer created a 'PUMA' case and was instructed to replace all the cam shafts and followers on my bike. Apparently, the 'soft cam' issue is more widespread than we had thought. At least BMW is admitting to the issue now. The job took a while, with some parts having to come from Germany, but my 2014 R1200GS is now back on the road. It sounds much better now. It still has that BMW boxer personality, but no more ticking / tapping noise from the engine heads. Just for reference: my GS is a 2014 and has 19K miles on the clock.
I owned a couple WC..
Nice bikes, though I surely wasn't a fan of the sounds of the engines/drivelines...
Glad yours seems better/fixed now... enjoy
Maybe you could post a video of it now as a comparison.
I listened to your video, it sounds like my bike. I think you are fine.
Good idea. Here are 2 videos - Before and After - for comparison. They were both taken in the same place, with the same phone. I can hear a difference, but it's not as noticeable of a difference than I had originally thought. What do you guys think?
i think it was all in your head my friend. or maybe its difficult to differentiate in a video. that's why i said my bike sound the same as yours. it also sound the same as your second video .
Yah..To my ears, not too much of a difference between the clips..
"After" sounds a little better / the clatter, slightly less pronounced
Could be other factors at work. garage door up or down, humidity, operating temp, ambient temp....
Many would say it's sounds fine or good...normal in both clips
As I wrote, I had 2 WC, nice bikes, but I am not a fan of many of the sounds from these engines/drivetrains...
I can't post a sound clip, but to me, either one of my Camhead Boxers, '10 GS or '13 RT sound much more appealing to my mind's ear.
Learn to accept it as normal if you can...because maybe it is.
All bikes have quirks, and the WCs` are overall, very nice designs.
Or, bail on it, which is what I did. New owner of my GS WC, last I spoke with him, was very happy with it.
Upside for you, If I remember correctly, there will be extended warranty on the items that were replaced.
As I recall, the new parts would be warrantied for 2 years...not sure about the labor.
this thread got me more curious... so today i tried to listen to my engine, and maybe my valves/cam/lifters are indeed quieter than your video, on my bike i cannot really hear it from 3 feet away to the bike. I can hear it if i come close to it and really listen to it.. but that's super normal, i mean valves, lifters and cams are noisy, there is a physical contact between cams and valves.. Usually a THICKER OIL will do the trick and make it quieter but who cares..That's what i do on high mileage cars i have.. maybe in the future you can go with 10W40.. or 20W50 (that's super thick, may not be good for your engine if it's new with low miles...)..
so maybe your video is not doing your case justice since the volume of the noise would be even'ed out when you film it and now that you have new cams!.. well.. no harm in that.
all in all i would not worry at all about these noises.. i had a bmw 5 series before with hydraulic lifters... and those were super noisy at some points. Dealer replaced them for me (under warranty) because i complained so much... but all the guys i know who own bmw cars had the same issue, but there were never really a problem in driving or performance or engine life.
Xzatx: you do realize that the OP had all of his cams replaced under warranty due to an issue? He wasn't being dramatic, it wasnt all in his head and this wasn't a case of "put earplugs in and ride it."
yes .. thats why i said, u already replaced it so.. its all good.
Thicker oil will also mean power loss, MPG loss, etc. @browneye and some others have tested this.
