thread sealer anti corrosion isn't thread locker
If you can get straight in with a drill then yeah, they can be fixed on the car.I have a question. Both of my 18 mm vertical bolts fail to torque proper. Just finished a timing belt change. Can these the threads (Time Serts) be added with the motor mount bracket attached to the engine? If so, seams like a good alternative.
Thanks
I did it this way. Wasn't fun, but I managed. Sadly, I didn't tap on hole far enough and I ended up having to cut the insert off (with a dremel), not a lot, but I wasn't happy I messed up. Been over a year and 25k+ miles and it's holding up so far. Take your time.I have a question. Both of my 18 mm vertical bolts fail to torque proper. Just finished a timing belt change.

One of the reasons this repair or a Heli coil repair is stronger than the original threads is that after the repair the load is now spread out over a much larger area.while these thread repairs are nice your assuming they are stronger, your screwing them into aluminum which is the weakness in the first place
Yeah. I have wondered that myself.Not sure if I'd mentioned it previously, but there was a reason why the mounts were designed like they were (highly questionable as it may appear), and that's for safety, for engine breakaway in collisions. I don't have the capacity (resources, including mental) to figure out what changes a changed mount like this presents to the breakaway function, but for sure it's altered. Mind you, I prefer the strategy of not testing, of not hitting anything in order to find out how either this "design" OR VW's operates!
How do you get a tool in there to hold the bottom nuts while torquing the bolts? Can maybe be done on a bench, but not in the car.There are basically three ways to fix a stripped motor mount:
- (1) Replace it with a new one [expensive]
- (2) drill, tap and pray [lots of labor]
- (3) make it work 100% by using nuts [never worry about mount again]

Wingnut; There seems to be a miscommunication for which I do apologize. The YouTube video would answer all your questions and it is only 8-mins long (I made it to better show the assembly).How do you get a tool in there to hold the bottom nuts while torquing the bolts?

I have to disagree with your claim that the drill & tap repair is "lots of labor" It's a 10 minute job. There certainly is a lot more labor time to cut those slots in the mount to accept the nuts.
I agree that the cost of the time sert tool is expensive and if you are just doing 1 mount, the cost to buy a new mount makes sense. But there are options after buying and using the tool. Repair more mounts at $5 worth of inserts each. Or sell the tool to recoup some $$$.

This. A thousand times this.Engineering of these 'systems' is quite remarkable. I can honestly say, I'm alive today because a Jetta sacrificed it's life to save mine. The point being, don't mess with a connection whose design is to fail in a catastrophic incident and in a way that may save your butt.
You are correct, the mounts actually break, not the bracket. I have an 03 Wagon with a 1.8T engine, hit hard in the front, it broke off both side motor mounts, the brackets are intact.Not sure if I'd mentioned it previously, but there was a reason why the mounts were designed like they were (highly questionable as it may appear), and that's for safety, for engine breakaway in collisions.

Its weird, some accidents you'd swear the air bags should have gone off but don't and vice versa,What really did me service was the door curtain and the seat air bag. It was a sideways strike. The steering wheel bag never went off, which was a surprise.
