Engine Mount wrapping?

[dvs_dave]

As we all know the nearside engine mount succumbs early to the heat transferred through it from the exhaust manifolds. One option is to ceramic coat the mount arm to stop the heat soak but this is a bit of a mission and from what I understand a bit pricey. Would it not be easier and simpler just to wrap the mount arm in some high temperature thermo sheild tape whilst insitu? Would it not achieve pretty much the same results of prolonging the engine mount life?

Would like to know if anyone has tried it as I'm due to get a new mount fitted and would like it to last a little longer than the usual 3k miles before it starts sagging again.

Colin Harvey at SC Power has a kit for this alonng with high temp mounts

Yes I've seen these and made some specific enquiries with various specialists about them. As a consequence I've chosen not to pursue these particular products any further.

I know the high temp mounts are more rigid too so when cold maybe to harsh for some, if that's what you mean.

I chose to go ceramic coating route.
Bought a new mount got it ceramic plasma coated then just a quick swap over.

I do have a spare insulation jacket that colin kindly gave me, if you would like it email me

I'm currently looking for a LH engine mount and am considering the SC Power High Temperature polyurethane engine mount. Would the insulation jacket be a better idea? If Dave doesn't want it Graham, I would be interested!

[dvs_dave]

Hey Graham, thanks very much for the offer but after some consideration I reckon your plan of buying a spare arm and getting that coated is in the long run the best bet. I reckon that heat sheild would be pretty tricky to fit without dropping the exhausts, and if you've gone that far, it's not much more work to swap out the mount arm.

As you say the poly mounts are more suited to competition/track use rather than road use and I've not seen any information to confirm that they actually last any longer than the standard mounts?

How much to get it ceramic coated, and does it actually work??

[dvs_dave]

A new coated mount bracket costs about £100, plus fitting.

I found out that even on the later cars with the extra chassis heat shielding, the mount still fails due to the heat being transferred into it from the mount bracket that passes through the exhaust manifolds.

Coating the bracket will stop the only other possible heat transfer route.

Colin's mounts do last longer than standard, I tested a few on my car over a period, the heat shield is well worth fitting though.

I've had the new heat-resistant mounts on Sagaris since about Feb and they appear to be holding up well. The only difference is the slight vibration when she's cold, I suspect the mounts are designed to become flexible when at normal operating temperature..

Before that I had the "normal" mounts but the survived only 500 miles before ripping themselves apart (probably due to the freezing winter and some cold starts)..
