Has your car ever had a rear shunt or been in a front end accident? I've seen the rear engine mount from the rear subframe bent on one car that I did not buy. This will have the effect of pushing the engine forward and adding extra shear force on the mount.

No not that I'm aware of. it's not registered and has all original parts, nothing looks out of the ordinary at all when up on a ramp and I've had a few people look who know VX's very well. We spent about 5hrs under it last night doing various things!! It's very strange, I'm waiting on a mechanic friend of mine who works at Vauxhall to send me a picture of what he can supply as an original Near side engine mount, he can get them for £60.00, usually they are £80+ to the general public.

ok have some measurements, the old engine mount is 850mm high the new auto vaux one is 700mm high

[techieboy]

70mm is correct

Ignore the fact this is an upgraded aftermarket mount, the dimensions are exactly the same as the originals

[frankandbeanz]

Ok so the old one i took off has been stretched?? 150mm seems a lot, it is also a lot bigger in diameter then the autovaux one? The 200 yd test drive was quiet until bang grrrr.. strange thing though the guy previous said he has had this engine mount noise for 4 years??

[jules_s]

How odd, Is the mounting bracket bent or non OEM?

[fezzasus]

70mm is correct

Are you running vibrasonic mounts too? any impressions? my maths says that I should use them next time I need to replace my mounts anyway - plus I imagine they are similar to adding the poly inserts in terms of engine movement

[Duncan VXR]

They is a lot less movement verses the poly insert option DG

OK so I don't know how to upload images but the exploded diagram I just got faxed from Vauxhall shows a different engine mount than the one in the picture above ( I know it's aftermarket ) The one form Vauxhall is allot more bulky and bigger just like the one we took out last night...... It's Vauxhall part no 93172350, I need to show image but I don't know how!!!!

[techieboy]

Are you running vibrasonic mounts too? any impressions?

Nope. I didn't bother fitting them as I wasn't sure they really were an upgrade. There seemed to be more movement in them, than in the standard mounts.

[fezzasus]

One theory: the engine mounts have changed since the factory fitted mount, either due to supplier differences or to actually address the failures. If you only fit one, then you introduce an angle directing the force towards the new mount, increasing chance of failure. Replacing both removes this angle and puts it back to the original positioning, abit 15 mm lower. This will also change the bulk of the engine supporting from the top mounts to the bottom mounts, which are not known to fail. My guess is this is actually an improvement on the original based on the drop in height, but only if applied to both sides.

[Apex Graphics]

We fit new ones to both sides and it tore the near side one apart inside 1 mile!!

[slindborg]

850mm and 750mm........ someone has their units wrong

[Apex Graphics]

He meant 85 & 75!!

[frankandbeanz]

duh! finished at 2am not feeling good, 75mm i think gonna have to put it back on ramp and check middle mounts as the engine sits 15mm higher on the NS then standard il take a picture of this tonne of rubber and post it on friday..

[frankandbeanz]

ok to add to more confusion just been faxed diagram from vauxhall dealer the OS bracket is pictured in fax with 3 13mm bolts going into engine horizontally, but i can remember last night there were 3 13mm bolts holding the bracket to the engine vertically can any body clarify..?

[Phear]

If memory serves the Near Side ones are horizontal into the block, the offside are vertical into the gearbox. Thats on an N/A anyway.

[ChrisS1]

Photos of your current set up would help a great deal.
