Bad engine mounts are a big enemy of exhausts, failures of the flexible joints can be traced to excessive engine movement. A great video as always Charles.

[@HumbleMechanic]

100% right!!!

[@nestrac]

A friend of mine had an engine mount fail on his VW Golf mk2 diesel.... He drove it to another friend who is a mechanic and found that the only thing keeping the engine up was a ground strap to the battery....

[@mry82]

That's awesome.

Wow thanks man, exactly the clear and concise instructions I was looking for. Doing a lot of work on my 99 miata, control arms are out for new bushings, rad is out and replacing all the coolant hoses, as well as timing belt and water pump. The car has 145000 km and the mounts are original along with everything else so now that I'm this deep I'm sure you'd agree that I should replace the mounts as well. Thanks for taking away my apprehension of doing this.

Great video. One of the first mechanic things I ever did was with my neighbor who was thankfully mechanically inclined and worked on his 60s Datsun convertible, 70s Nova, 90s MB SL500 and 20s BMW 535. He helped me change my motor/tranny mounts on my MK6 VW GLI and I learned and he saved me about $700. I have since replaced those mounts with 034 Motorsport solid rubber (not poly) mounts. I love investing in middle market tools and learning to fix my car, learning all its systems and enjoying my car ownership experience. But unfortunately I will have to pay $1k-$1.4K for labor and $600/parts for chain stretch on my high mileage car. But I always see it as learning how things work and excited to tackle bigger jobs across whatever cars I own in the future.

[@markplenty2631]

I really look forward to your enthusiasm in every video! Thanks!!

This is excellent timing, my LW Ford Focus was recently diagnosed as having sagging engine mount/s. I drove it today and I noticed some weird handling characteristics coming from the left front tyre, could be totally random or tyre related, but yeh, when the engine is sagging it could affect things such as the anlge of the drivshaft etc.

This is very timely for me. I had a shop replace mine on my '99 Miata, both torn, at 70K miles when they did the clutch. Now I'm at 157K miles and with new vibrations I suspect they need replacing again.

[@dobroplayer7]

Great vid! Only thing I'd add is another symptom of bad mounts on FWD/AWD is pulling when hard acceleration as the engine shift.. also impossible to align. Thanks man!

I just bought a mk3 Beetle 1.8 turbo and I was thinking of changing the motor mounts then boom this video comes out... It's a sign

[@Patrick94GSR]

Did the same job when I was replacing my NB1 clutch and flywheel. Also found the driver side one completely torn, also at about 160k miles, exactly like in this video. I had the pleasure of also replacing the exhaust manifold, which made it WAY easier to change that driver side mount. For replacement I went with the OEM Mazda Competition mounts which seem like a good compromise between performance and NVH levels.

[@HumbleMechanic]

NICE!! Yea the exhaust out of the way, MUCH easier. HAHA

[@aubreybush5287]

Glad you made this before I start my engine refresh gonna go ahead and replace the mounts while I’m in there lol since it’s not too expense for the mk3 gti

[@HumbleMechanic]

yeah they aren't too bad!

[@Charkatak]

Good explanation! On my Acura, 3 engine mounts are covered with rubber boots, so I can't see the mount's rubber. I did acceleration test in D and R and engine had a usual movement. I do hear clunking(?) sound when I put my car from P to R, D and vice versa. Also when driving from 2nd and downshifting to 1st, I feel engine brake which is accompanied by a sound(thump maybe). Transmission mount is visible and has some cracks around the perimeter, but I don't see how this could be the issue.

[@viktorp8213]

I really needed this😁

[@dasautogt]

Interesting and educational. Thank you.👍🇦🇺

[@rennkafer13]

That broken drivers side mount is pretty typical on NA/NB Miatas. If you used stock ones and go autocross/track it will likely break again soon. Mazda Comp engine mounts aren't too harsh and last a lot longer.

[@aaardvaaark]

Eric the car guy had a great video of example of failed engine mount that took a while to diagnose.

[@HumbleMechanic]

They can get WILD!!! some Audis use the mount as a fuel pump ground. When the mount fails, it causes the car to run poorly

[@domusbr]

Really nice video very well explained, I'm going to replace the flex exhaust pipe on my car. do you think that old mount engines should be inspected as well? I want to make sure that the engine doesn't put more vibration on the flex pipe.

One time I noticed the engine was slowly turning in the direction of the rotation so changing the spark plugs became very interesting in that one side was lowering down. It was a broken engine mount.

Today I replaced tires for my car - Michelin 4 tires = $1005 . They also diagnosed replacement of engine mounts $2000 parts and $2400 labor. Looks somewhat expensive for me.

My engine mount on my 06 cobalt ss was so worn out that I could move it back amd forth with no problem....and it flexed so bad that I broke 2 flex pipes from it. I got a new solid rubber mount from zzp and it eliminated 90% of the wheel hop i had AND stopped 99% of engine twist on wot. I got the trans mounts front and back as well...totally changed how my car feels and what I can feel its doing just from the slight vibrations now. I know- what rpm in what gear = my mph.

[@braderyoutube1983]

will the degreaser oxidize the rubber at the mounting?

[@gilmello8296]

Back in the late 60’s early 70’s a broken driver side mount on Chevy’s would allow the motor to pick up so much it would hold the throttle open. Also if a car came in with a broken distributor cap, you knew it had a broken mount. The replacement was designed to to limit engine travel if the mount broke. They were also a pain to install

[@gvi341984]

Broken motor mounts are awesome. Made my car jump everytime when I pushed the gas paddle. Like I had a jumping gangster car lol.

Hey Charles, here’s a story you’ll like. A friend of mine bought a 2001 3 series coupe with a 5 speed manual gearbox a number of years ago from a cop in Yonkers New York. So much buffooning was done on that car. But the thing that struck me the most on the car was the fact that the previous owner welded the rear shocks into place so that they wouldn’t rattle around. Needless to say there was many hours of grinding and swearing involved in order to get the stupid things out.

[@HumbleMechanic]

What the heck!?!? That’s probably 10x more work than fixing it right

[@mds2465]

[@jasonschannel1315]

I have a question I have a 2016 kia soul when I go over bumps I hear Clunking noises and I have no idea what that can be and mechanics these days ain't cheap. It shifts fine I don't hear no noise but the vibration has gotten worse since I replaced the top motor mount. Now I understand all the mounts are supposed to be replaced all at once. Just out of thought would you think it still could be the transmission mount. I can't find no info on Google.

[@miketeeveedub5779]

Bought a motor mount kit for my mk1 Jetta - will definitely follow your guidelines when installing them this spring. Btw - leave it to VW to requiring a motor mount alignment upon replacement! 🤣 NOTE: If you guys want to see pics of my Mk1 - go to Imgur and search for "My 1984 VW Jetta GLi Coupe".

I recently had my attention called to a bad set of mounts on my mk4 when I quickly let off the throttle after accelerating - it make an audible clunk and upon checking the mounts, the engine side had the aluminum rod insert completely slide out with zero effort from the body end of the mount (ALH mount).

[@WhiteKnightDrifter]

i notice there is a "N" on the engine mount of this miata and therefore it's quite obvious if it has failed , unfortunately, I have a MK7 gti & I;m unsure of the condition of the engine mount , I believe the mounts should be the same as your golf R. Would you be able to share how to tell on the condition of the mounts on vw cars ? Thank in advance

[@crazyeyez1502]

Thoughts on aftermarket "performance" mounts? Threw a set on my old 2.4L Grand Am yearrrrs ago. Definitely stiffened everything up. They claimed that you can 'reclaim' or 'free up' (not add) 10-15tq. I had no way to measure that, but it did feel a tiny bit snappier off the line. That is, until the polyurethane inserts in the lower dogbone disappeared and the extra flexing of the engine blew out the exhaust flex pipe......

[@wickedgood1984]

So Mazda use German torque specs too? 27-38 ft lbs translates to Gutentight 🤣 Also, I just wanted to point out that I’m loving your filming transitions. Especially when you are placing yourself in the same shot multiple times. Oh and that transition when you panned past the lift post was amazing!

[@guilhermeg345]

Seeing this video made me remember when I changed the timing belt on my vw 1.6 tdi almost 2 years ago (first time). I completely forgot about removing the dogbone mount even though it didn't mention on the erwin manual and didn't see any tutorial/video mentioning it so that helped forgetting about it. I'm now imagining jacking the engine up and down as I needed but I never checked if the dogbone mount was getting crooked or touching inside the hole of the subframe where it bolts. I used some wood blocks to limit the travel in case the jack failed. My ocd is triggering me right now, what damage could I have done by jacking up or down beyond the limits of the dogbone mount ? Please help.

You’d have to really really crank the engine to damage the mount. I’ve seen this done tons of times. Never one damaged

I replaced the mounts in my GTI and there was some minor harshness introduced, which got very noticeable after a single mass flywheel was installed. Lots of low RPM clutch chatter harshness and an idle like a 1030's vintage farm tractor. Weird that there is almost no added vibration. Edit: "Stage 1" urethane mounts, not stock.

[@jesusamador9726]

On the torque specifications there are two different torque settings you did not torque the bolts correctly. The 1st torque settings is to get everything lined up correctly and then the 2nd torque settings are the final torque settings. The torque settings are usually two different settings and that isn't so you have two options it's to torque ( 1st settings) bolts in place then the (2nd settings) are the main and final torque settings . If you don't follow the directions for proper installation of any part the part isn't going to last very long.

[@HumbleMechanic]

None of that is listed in the repair manual.

[@azarahwagner2749]

With the upmost respect , honestly I am not yanking your chain or anyone.... The manuals for torque wrench kits don’t remind us of service manuals where it shows say ... 14 - 22 ft- lbs for instance. The first designation is actually for WET torque and the second for DRY torque settings. If the hardware has oil , grease , water or some combination choose the first . It is friction that holds the treads but when wet ( even a small amount) the bolt will grab tighter so in fact , it holds higher than the setting is and would end up very close to the DRY spec . Too many people end up snapping the wheel studs due to over torquing because the hardware is wet and choosing the DRY spec . I hope this doesn’t insult anyone and I am not trying to embarrass anyone Love the videos , they are very helpful

[@HumbleMechanic]

I love this comment!!! I come from the German car repair world. The spec is the spec. If the bolt is lubed you still torque to that amount. But this makes perfect sense. It just makes me uneasy, when there is no qualification haha. Great comment
