Just look at it from the back.

I cut up an old K&N air filter and slid it in between the pan and cross member until I can put some good mounts in.

karl ruiter

Thanks for the warning. I have still not installed mine and will test them.

Bill Ball

I remember Carl having this problem with Anchor. So, even though Corteco uses a different PN they have been screwing this up regularly, requiring you to screen all the mounts? Argh!

danglerb

Would it do any good to check the mount by sticking it in a vise and putting some pressure on it, see if it collapses.

Roger,

So the ones you shipped me on about January 18 should be fine?

SeanR

Yup, this last batch that came in after that, had some bad ones in it.

ROG100

I can't say 100% that they are OK - if they can ship one bad batch they could have shipped others.
Please check to make certain.

Danglerb, Mike, You could put them in a vice and apply side pressure.
You can actually do it with your hands as said early in the thread.

If they are out of the car you can weigh them. Without the nuts, washers and spacers they weigh 1 Lb 12 onz. If they weigh more than that they could be suspect.

Bill Ball

That's good. I have a set bought early this year but not installed yet that I will weigh.... EDIT - Back from the garage. I get 1 lb 8.8 oz.

ROG100

Just for the record - I always stand by my product and will be replacing all bad MM's with new good ones free of charge including shipping costs.
I doubt I will get any joy with the manufacturer as they are not being used for the application they were manufactured for.

ROG100

Bill,
Weighing is just another indication but by far the best way is crush them with your hands or put them in a vice and squish them. You will know immediately which is good or bad.

Well on the bright side of this I'll get to try to set a new time record for doing the motor mount job. We think three hours in and out should be a good goal. Don't have to do oil pan gasket so it should be easy peasy just like the last time.

fraggle

Application or not they screwed up manufacture and should replace them. I doubt the ones they sent you would work in any application.

Hi Roger could you see my invoice when i purchased mine? just to be safe...

danglerb

Having the MM collapse sounds like it could present a serious hazard if a person isn't careful about keeping hands and fingers out of potential pinch or crush zones while installing MM or working on a motor.

Any thoughts on a premium source for MM's, not solid, but maybe something like Prothane?

Unless you have arms long enough to be on top of the motor lowering it down to rest on the motor mounts from the motors temporary supports this is unlikely. If there's two of you finishing of a motor mount job and you are discussing it here it would be a reasonable assumption that those playing along at home would be sensible enough to keep there hands and other small bits out of crush zones. Don't bring PC nonsense here.

Working on your own car exposes you to more risk than just staying safely tucked up in bed. Yes there are some risks that aren't desperately obvious and everybody here will I am sure try very hard to make sure they make those risks as blatantly obvious as possible.

But, there are risks that should need no explanation, like putting one's fingers in a vice and then tightening it oneself. If one is in danger from those sort of risks go home go to bed and stay there.

Irrespective of how good my engineering knowledge is (it's good believe me) I wouldn't be under a car while I am in charge of lifting or lowering it , and I wouldn't let any one else be either. similarly I wouldn't let anybody have there fingers or other small bits in between stuff that was going to get closer together. But thats just common sense isn't it?
