336 cam made in china
 
Some mention made in a unrelated thread about how the 336 cams made in china were crap and had been recalled by BMW so how can I tell if a cam I purchased about 3years ago was made there?thanks arch

There is so much BS floating around about 336's. I hope this rumor is just more of it.

I found the problem with the 336 cam about 16 weeks ago, I DID post the problem within one of s/s cam debates but I think he missed it. THEY ARE MADE IN CHINA AND THEY ARE ALL SCRAP. THE LOBES ON THE RIGHT HAND CYLINDER HAVE BEEN MISGROUND AND WRECK THE FOLLOWERS. THEY MADE HUNDREDS AND IT GOES BACK ABOUT 2 YEARS. AT THE MOMENT BMW HAVE THERE HEAD IN THE SAND, AND ARE HOPEING THEY ARE OUT OF GARANTEE BEFORE THE PROBLEM IS BAD ENOUGH TO BE NOTICED.

I remember your post. I am still hoping that it is not so. A story like that needs a verifiable source. Who is it? We all know that a cam has never been mis-ground in Germany but . . . . On the other hand, BMW has been farming out airhead parts manufacture to some crap suppliers lately.

John would be a verifiable source in my book.
Wost case scenario be would be an identifyable source with a current international profile and a reputation as an engine builder and parts manufacturer.

I hope the 336 china scrap story is and urban myth but I'd be listening to what John has to say

"THEY ARE MADE IN CHINA AND THEY ARE ALL SCRAP. THE LOBES ON THE RIGHT HAND CYLINDER HAVE BEEN MISGROUND AND WRECK THE FOLLOWERS"

At face value he has identified the problem on more than a single instance. Sure I'd like more info but I'm not going to ignore this advice.

So perhaps this explains why the 336 cam I put in my BMW R100gs shit the bed and ate the rockers on the right side.

supershaft 05-16-2011 05:26 PM

Don't get me wrong. I am listening but a bad batch of cams doesn't mean they were made in China. I thought he said he had a good source on the origin of manufacture? If it's true, it's a shame. I would find out who made them originally and try to get cams through them since BMW has (had?) about the best cams in the business IMO.

I have got NOTHING good to say about my experiences with Chinese bearings and whatnot. Junk right out of the box!

Ok..... Here we go again!

Who is reporting these multiple instances of bad cams and what kind of numbers are we talking about?

I;m not saying that it dint/doesn't happen but I'd sure like to have some confirmable data.

I have been informed by BMW GB that they were made in china. the old stock ran out about 2 years ago, they will not tell me how many that BMW AG had made but we know it is more than 300. they owe me a lot of money for engine damage, I DONT want to take them to court but it may happen.

Re: 336 cam made in china
 
Getting back to my original question, how to tell if they were made in china? Are there any special markings or would they have to be measured and compared against a good cam? Arch.

supershaft 05-17-2011 10:37 AM

I am still barely hoping that it ain't so. I know BMW NA has been a source of a lot of BS in the past especially regarding 336's but I would think BMW GB knows a bit better. Even the best has been known to make a bad batch of cams but I have little faith in a Chinese manufacturer making them right when they can sell junk for less.

We are doomed if they start farming out to China. I just put some big front wheel drive needle style Chinese wheel bearings in my truck. They literally didn't make it around the block. Timkens fixed it at $80 a side after I shopped around and got the lowest price!

Chinese hose clamps! :rofl But they cost half the price of ones that actually work! :rofl
