im thinking of putting a solid engine mount into my mk2 golf.how much better are they. is it worth it any one got any opions on this
-
i know its a bit different as i have a vr6 conversion, but i've recently fitted a new solid front mount to mine.
the handling feels a bit more precise, gearchange is a lot better (5th was sometimes a pain) and i know the engine moves a lot less as it used to rub on the chassis leg when corning hard left (clearances are a bit tight) but now it doesnt.
apparently they can cause a bit more vibration in the cabin but i havent noticed any.
-
Worth it if running a VR otherwise I would standard would be fine.

A few mates have had problems with solid mounts.
Broken engine mount brackets.

if you have a poor quality 4 branch with an inadequate flexi section then a solid mount is a good idea, will help stop it cracking. apart from that you dont really need one.
-
soild frount mounts arn't normly required, most ppl who have them don't get problems as he frout crossmember is on rubber mounts but if you poly bush the frount crossmember the frount mount bracket will snap

Personally, I would not bother with a solid mount unless you have a track car with a performance engine in it. And then you would need to keep an eye on other structural members for abnormal wear and tear.

i replaced the crossmember bushes with OE rubber ones when i fitted my new solid mount, so hopefully i'll be ok then! :huh:

ive got a homemade solid front mount on mine (165lbft can cause a scary amount of movement on the dyno) and comfort/nvh wise its fine as the remaining rubber ones still allow a bit of give with the solid one just acting as a hinge really, if your old one is shot it will make the gearchange seem slightly more possive as the rods stay still while the engine is wobbling around. definitely do the crossmember bushes while you are at it though, and use quality bolts (the vast majority of automotive bolts are 10.9 grade- 8.8s are easier to find but weaker and 12.9s are a little dearer but VERY strong and are the ones you want)

Don't wish to be a spoilsport, but isn't the whole point of an engine mount to absord some of the movement/vibration from the engine. A solid mount would negate this.
This can only lead to the failure of other parts that are now exposed to - and not designed to take - excess vibration and movement.
Think! If the engine mount isn't absorbing/suppressing vibration and movement, what part of your car is?

the two rear mounts.
the cross member bushes.
the chassis of the car
suspension bushes
:rolleyes:

yes they are meant to for sure, but they are designed so your mum can bang over speedbumps in comfort and you simply would not believe the movement from even fairly modest power outputs.
another option if tyou can be bothered is to make up mounts with smaller rubber bushes in ( *cough* transit leafspring) so they are much firmer but still padded a little. more hassle but more proper and a not uncommon sight in the less convenient engine swaps like vtec into old mini or virtually any off road racer. the engine itself only needs to be secure and not strained (obviously the mounts do take load when the engine is working- i mean the need to fit properly not be hammered in or pulled into place with the bolts), you still often see mk2 escorts with hot pintos and sierra cossworths advertised with a 'wcxm' (world cup cross member) essentially a completely solid pair of engine mounts fabricated onto the subframe, likewise in f1 cars (okay im pushing the point a litle ;) ) the engine is a stressed member. Some tvrs and se7en replicas are solid mounted too, its fine as long as its strong and straight.
The mounts are there to make your car feel all pc and living roomy in the showroom/when whatcar test it, most well prepared track/race cars will have beefed up firmer mounts.
