engine mount change - my experience

wilsonny · Apr 1, 2015

Just thought I'd share my experience of changing engine mounts on my 993 C2 and say that if you haven't done so already, the effect on the stability of the car really is as good as certain websites would have you believe.

I've went for the std. C2 mounts (rubber and hydraulic) rather than any of the stiffer options (C4 or RS) and it's made the car feel far more stable at speed, particularly over road undulation.

You can see in the picture, how much mine had dropped - old one is on the right. This wasn't so visible when it was on the car, but you could see the gap a bit. My cars just short of 60K.

My level of knowledge and skill level is much lower than lots of others on here, but I must say that having seen these mounts supporting the rear of the engine, I certainly won't be about to raise the rear of my car by jacking under the engine as suggested on many Internet sites. Doesn't seem right to be jacking up against these flexible mounts that just cost a tad of money to replace. That's just my opinion of course.

Anyway, if you've been considering changing these mounts, I'd say go for it !

Cheers

Great summary Andrew.

Did you use genuine Porsche items as the replacements?

I've just done the mounts over the winter at 59K on my car - I'm sure they've never been done before. I didn't change anything else, so I can be sure that the improvement is down to these.

I got the mounts straight from my local OPC (Kendal). I couldn't see them anywhere cheaper for the original items anywhere else - £525 for the pair. I believe these C2 ones are actually the most expensive ones. Maybe someone else on here will advise if they know anywhere cheaper. Couldn't quite believe I saw someone selling secondhand ones on Ebay, but I suppose you takes your chances !

My car has been fitted with RS engine mounts and the difference to worn std items is very noticeable. Well worth it.

+1 RS mounts, the Rs gearbox mount did increase NVH slightly

Today i have changed the rear engine mountings, What a difference,

First thing the first to second gear change much improved,
all the jerky ness when creeping in traffic has gone,

The car feels much more stable at speed,

They were the original mounts that have done 80k.

Charles,

Did you take the opportunity to upgrade to a different type of engine mounting or keep it standard?

chas3.2 · May 14, 2015

Went for the C4 ones so a bit stiffer.

Went for the C4 ones so a bit stiffer.

What's involved in changing these, Charles - straightforward?

Hi Paul
The right one is easy. But the left is much harder if you have A/C as you have to lift up the compressor,

and the pipes undoing two clamps first. On my car the mental tube witch guides the engine lid cable,
Gets in the way of removing the L/H mount so had to bend it out of the way.
You will need to jack up the rear and put it on stands so you can remove the under tray.
To get to the 18mm holding nuts.

About a 2.5hr job.

i followed the instructions on here, although they are fitting rs mounts, the procedure is the same for the std ones

http://www.jackals-forge.com/lotus/993/RSmounts/993_rsmounts.html

with regard to the left one, i also found that more difficult with the tube on the engine release. a top tip is to rotate the mount before trying to remove it. the std mount plates aren't the same dimensions on either side, so rotating it after unbolting can give you a bit of extra room to play with on the way out. same on the way back in...if you see what i mean.

one other thing, it may be low tech, but i used a scissor jack to hold my engine because it gave me very fine control of the height during the procedure.
