Poly engine mounts

[Nick Mann]

Easy enough to do if you have a vice, a hack saw, a hammer and a chisel. IMO there is absolutely no point doing one. If one of your mounts is dead then I'd be amazed if the others were all good. If there is sag in the other three mounts and you put one good one in, then it and the remaining sagging mounts will be under more pressure and will potentially fail faster.

If you are going to do it do them all. Great upgrade as well.

[disco-ian]

I really would like to upgrade but would rathe do it when I actually have the money rather than adding another £100 to debt.

A member has just replied to my wanted add so see how much he wants for one. But I'll still upgrade if costs work out against a second hand one.

Little update.

Noticed that my rear engine mount bush got worn. Other 3 perfect.
My question, which is the right catalogue number for rear mount? I got 2 different numbers refered to rear polybush:
13-508 (here: http://www.ebay.co.uk/itm/2907941785...84.m1423.l2649), that one I had fitted, but seems got misshaped with time.
13-506 (here: http://www.ebay.co.uk/itm/3603319202...84.m1423.l2649), that one looks more solid.

Anyway, previously in this thread both bushes were referred as right one hence got confused.

I have alway used the Holey one from the first link and never had any issues with them. I fitted the polly mount to both of my VR4's and the last lot have been in for a good couple of years now so I can't complain at that.
I don't know if the second link mount would fit to the rear roll stopper, but if it does fit I don't see why you can't use it, it will make the forward and back motion stiffer and this will be noticed on gear changes and hard acceleration.
it might induce more vibration in the car at idle though.

Tomasz, the one from the first link is the correct one - the other will not fit.

I'd suggest to change the front roll stopper as well. Otherwise the front one will be worn within days, as it will take all the roll energy.

front roll stopper insert: 13-505
rear roll stopper insert: 13-508

Stefan, I have polybush in front mount. Good as new. Side poly mounts good as well.
Dave, potential vibrations ain't my worry, already you can break you neck in my vr4 driving thru speed bumps
That one knackered was identical with quoted in 1st link. Apparently seems that additional holes makes it weaker. Centre hole become misshaped and "oversized" horizontally by 8mm and vertically by 4mm. Obviously increased torque and stiffer suspension had its own contribution.
Hence my question regarding second option, as looking more solid build.

[peter thomson]

I can't remember if I posted this before but I filled the holes with aluminium bar of the correct diameter to give the effect of a soild bush

I will copy your solution sir.

[Davezj]

That is a good idea i never thought of that.

i think you would have to remove the rear roll stopper to enable you to fit the metal bars/tubes to it though. it is a shame they can't be slid into the mount after it is fitted, as a retro fit if you want it stiffer..

pete can you remeber what size the bar was?

[peter thomson]

I believe it was 12mm diameter

Everything is removed now Dave. Little overhaul commenced at PSB workshop.
Emptied engine bay, few wires and vacuum hoses laying around and 2 engines sits next each other.

Sound like you are having fun tomasz, keep us all posted of your progress.

[millzy_88]

So my current mounts have worn out, 5 years wasn't a bad stint. So I'm wondering, last time I bought these the front mount didn't fit, do we now have a front roll stop option that's direct fit?

[CANDEE]

Matt,

Its front roll stopper insert: 13-505, which the kit now includes.

[millzy_88]

Awesome, that makes life easier. Will do them all now.

Sorry for not reading this all but signal pants & can't keep loading each page. Engine mounts, currently fitted to an ex auto / manual conversion, will these fit a genuine manual if an auto box mount is supplied? If so, which one or am I going slightly mad(der)? Sorry again but better than creating a new thread

[CANDEE]

Chris, the auto and manual gearbox insert is the same size, so if you get a kit it will fit either way.

[Kryton]

Cool cheers for the confirmation

[Davezj]

But just to confirm, the auto and manual gearbox metal part of the mount and you can't use the metal part of auto mount on a manual gear box and vice versa. Poly insert as stated above is the same.
