SENNA1 Posted September 13, 2010 Share Posted September 13, 2010 Hi guys, i'm planning to interchange my cav's mk1 engine mounts with the above mentioned. Anyone of you who have done this before-is it worth it or not? Regards. Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted September 13, 2010 Share Posted September 13, 2010 hi. i have 2 mk1 cavs. both with standard factory engine mounts. i have never had a problem with these over all the years i have had mk1`s.one of mine is a 2 litre. other is a 2.2. later cars (mantas in particular) had an alternative fluid filled mounting fitted .i presume this was to reduce noise ??. you could fit early senator/royale/monza mountings as these were same fitting but a slightly longer rubber area. harder mountings will stop any excessive movement of engine but transmit more engine noise/feel through to you.

mantasrme Posted September 13, 2010 Share Posted September 13, 2010 If you drive over-aggresivly with standing starts/ dumping the clutch etc you can rip the NS rubber mount apart Replacing it with a more solid rubber bobbin is a very good way of stopping that problem. If you replace both engine mounts you will get a lot of vibration/buzz through the car from the engine If you're looking at the pair from E-Bay For £29+£5 delivery then i would recomend looking here RallyDesign They have the same item for £6 each plus vat and delivery Quote Link to comment Share on other sites More sharing options...

Thanks again Yes, i just change the NS mount for one of the HD bobbin style ones. Been running that setup in my road-rally car for a few years now without a problem. We changed both in my mates car and noticed an increase in the vibration transmitted into the car from the engine. Quote Link to comment Share on other sites More sharing options...

mantasrme Posted September 14, 2010 Share Posted September 14, 2010 If you have not got a problem with the original rubber mounts then you don't NEED to change them. If you have had a problem it will most likely be with the NS mount (to clarify as you have a 2.0 CIH engine thats the starter motor side) Changing to a HD bobbin on this side will solve the problem (if you have one or you think you might have one) and is a good idea. Changing both mounts shouldn't be needed, and if you do you will feel an increase in vibration and noise from the engine. The OS mounts don't normally give a problem as the way the engine rotates pushes into that mount while pulling at the OS which can tear them apart. Hopefully that clears it up for you Quote Link to comment Share on other sites More sharing options...
