It's About That Time Again, Timing Chain Making Noise
As the titles says, my Timing Chain is starting to make noise again. It still sparatic right now. Cold starts only (cold engine that is). Usually goes away after 1 min or less of running.
I know there are a lot of timing chain kits out there. WMW, Outmotoring, ECS all have their own kits. It would seem that some of these kits have different parts. Which one out there has best kit? Should I get the one with the most amount of parts to replace? Or is that over kill?
Also has anyone ever tried Cryo treating these chains? This would be my cars 3rd Timing Chain set and 5th timing tension (From what I can tell on the carfax report I have saved from when I bought it). I figure if I have the chain cryo treated maybe it will last longer than 20k miles.
My car already had the lastest parts installed when the recall was released so there is no hope for warranty coverage on this one.

Engine runs smoother huh? Thats a interesting side effect. I didn't think it ran too rough for a 4 cylinder, but I'll take what I can get.

I believe that he meant that, as he has commented before, the plunger on the tensioner operates much more smoothly in and out than the previous iterations. (Not sure if that was comparing to a worn one or a new one, though.)

You could easily push it in with your thumb!

No problem, we mimic the dealership replacement parts & hardware, also this is what they used in the R56 S 07 -08' timing chain replacement TSB.

I would always buy from a Forum Supporting Vendor.
Customer service is hard to come by these days, so when one of them steps up like ECS to take time to answer questions... its worth buying from them.
Just for the record, I noticed ECS has replied to this thread and I have not purchased anything from them... yet, but will in the future.
When I ordered my chain replacement... the noise I discovered was not the chain but the vacuum pump. It would send noise all the way through the cam so it sounded as if it was resonating inside the chain cover. I tore all the parts down to find my chain was okay, tensioner working properly and by removing my vacuum pump altogether, the noises I had were gone!

Cryo Treatment
Hello,
Detriot Tunning sells a kit that's Cryo treated. However, they don't state the part numbers and which manufactured they use for cryo treatment. If you call them I'm sure they could elaborate on that matter.
I decided to order from ECS to guarantee the appropriate part number. I also used NitroFreeze to cryo treat my timing chain as well as the tensioner. (Nice people, talk to Jordan Andersen @ NitroFreeze.)
Chain Tensioner - #11317607551 82mm
Timing Chain - #11318618317
I actually haven't installed the kit yet...
Question:
Should I be installing a 78mm tensioner or 82mm on a fresh install?
correct me if I'm wrong, I believe the most recent tensioners are as follows:
• 11317597895 for the 78mm
• 11317607551 for the 82mm
MCS has 75k and this will be the 3rd time for the timing chain replacement.

Just an FYI.
The newest timing chain I believe is 11318618317, same one used in the N54. According to IWIS, they have a new coating on the timing chain pins called TRITAN. I don't know for a fact whether this specific chain has this coating. It's all speculation at this time. Could anyone verify if this applies?

This week, I took my 2012 JCW clubman (N14) with 34k miles in for a minor cold start rattle. I didn't think it was that bad, but my warranty was running out and I wanted to get it checked out. I left the car overnight and sure enough, rattle confirmed, timing chain was measured at 71mm, and everything was replaced. Bits of the cassette were also removed from the oil pan. Based on this thread, it looks like I have the latest chain and cassette part numbers. Does anyone know if these newest parts "cure" the problem?
I purchased my car used with 12k miles, and changed the oil every 5k miles. I bought a Craven dipstick at the time of purchase and check the oil regularly. I burn maybe 1/4 to 1/2 a quart between 5k intervals and the engine has always run very well. Although not unexpected with the N14, I'm pretty disappointed that my chain failed, even with religious care.
Is chain failure to be expected in another 30k miles even with the newest parts? I bought the Mini "Large" extended warranty while I was at the dealer, so I should be safe, but still ...
Here is my invoice:

Most people that had the latest chain update and tensioner kit have said its smooth and quiet. After they do the timing chain you should be pretty quiet. That's pretty low miles for it to be done. Sounds like the top T section and cassette came apart.

Yes, the engine is much quieter and smoother, which is a plus. Hopefully it will last.

Nice job posting the same sentence in every thread in this sub-forum. I do not think my Mini is a POS. The N14 timing belt issue is well documented, and I was well aware of the issue before I purchased my JCW. Every used Euro car has its share of issues -- it's just a tradeoff you need to accept. Otherwise go buy a boring Toyota or Honda.
I love the performance and handling of my JCW, despite its known issues. I plan to enjoy it for a few more years before I move on to my next car.

That's great news. Thanks
