I have a CP-E Rear Motor Mount which I do like but I'm getting annoyed because I have to tighten the bolts on regular basis.
I tightened the bolts a couple months ago after the car started making noise when disengaging the clutch, or even when I started the car.
As I start the car, I hear a fairly loud banging sound because the motor moves and so does the RMM.

I put some red thread locking thingy on every single bolts.
Two bolts I think are not the problem since they are covered by the metal casing and nuts get tightened on top.
The one on the driver side gets loose and so does the big arse one on the bottom, I believe it's the 19mm (socket size) one.

I'm assuming that it's going to happen again, in which case, I'm going to safety wire those two bastards.

Anyone else has a similar issue?

But serioiusly, did you torque the bolts to 80 ft lbs?

85 ft-lbs

If you're seeing one of the little 13mm ones in the trasmission loosen, you may have stripped some of the threads.

The big hex bolt could be missing a lock washer?

The 19mm on the far back could just be stretched. They are technically torque-to-yield and should be replaced every time it's disassembled.



I have the same RMM and assembled with loc-tite blue. No problems. In fact, I had to remove for my turbo install and the bolts were borderline difficult to remove.

The only bolt that I can't tighten to spec is the one on top because it's pretty much impossible to put a torque wrench back there...
The hex bolt does have the locking nut on but that one I think I didn't torque to spec. I think the 19mm one is the one that's causing me grief even though I use the red loc-tite.

It took quite a while for the stuff to come undone but since the first time I had to tighten everything again, it just gets out of whack relatively quickly. I'll find a fix for it.
Thanks for the advice, appreciated.

Hmmmm I have the cp-e stage 1 and haven't had any issues in 1k miles. How long does it take to loosen up? I only used loctite on the big bastard that goes through the center of the motor mount.

just get an impact gun on the bolts and hold the trigger on each one for 2-3 seconds
