Engine Mounts

PostPost by: 111Robin » Thu Jan 27, 2022 7:31 pm

I bought a pair of new engine mounts but notice when I place them side by side one of the mounts sits about 1/2" lower than the other, is this correct ?. The old pair are identical in this respect.

The new mount on the bottom RH of your photo is for the carb side of a 2 seater Elan with Weber carburettors, it tilts the engine to give clearance under the carbs. For the Plus 2 both mounts should be the same .. as per your old ones.

Thanks. I was clear when I ordered them it for a +2, I'll get back to the supplier.

Many suppliers, including some of the well known specialists don’t understand the requirements for this!

As explained, the new mount on the right of your photo, actually lifts the engine on that side. Required for a two seater with webbers, but if used on a Plus 2 will cause your cam cover to interfere with your bonnet!

Where, then, lies the answer? In choice. Which shall it be: bankruptcy of purse or bankruptcy of life?

I will have it changed, but in reality would it make any difference if the engine was tilted on the +2 ?.

Sorry I was editing my post as you were writing. Yes it will be a problem using the non standard mount!

Take a look at a Plus 2 with the bonnet off sometime. See how high the front of the cam cover on the twink is. It may surprise you?

Thanks, I was just curious, I'll certainly be using the correct part, good to know the difference though, always an education rebuilding an old car.

Not the greatest view, but these are the normal mounts. Hopefully you can see what I mean about the front of the engine sitting high. A ‘highly regarded’ specialist near Peterborough got this wrong earlier in this cars life and caused me a number of problems!

By the way, if you look closely in the parts manual, it’s also pretty clear there what’s required! No criticism of you, but you would imagine the suppliers could read?!

I’d be pretty peed off if I was required to pay to post the incorrect part back to them! I would suggest the cheapest option for them would probably be to let you keep their mistake, and just send you the correct part!

Yes I retrospectively compared the two cars in the parts books but like you say a specialist would be expected to know this, I didn't just buy them on ebay.

Correct item is being sent out, I have to return the incorrect one but postage will be refunded. Strangely I was also told I could have used the incorrect mounting without any issues.

Yes you can generally tilt up the carb side using the higher engine mount in the plus 2 the same way as it is done in the Elan. However bonnet clearance is tighter on a Plus 2 and lifting the right side of the engine may give you a clearance issue in some cases.

Bonnet clearance from the front of the cam cover is extremely tight on a Plus 2. I have damage on the paintwork of my bonnet to prove it, thanks to a specialist in Whittlesey. Perhaps depending on how the body is shimmed on the chassis, I suppose hypothetically you might ‘just’ get away with it. But it’s still the wrong part, and totally unnecessary!

Strangely I was also told I could have used the incorrect mounting without any issues.


Mmmm! Why didn’t they just send you the correct part for the car, or inform you they were sending the wrong part, but it would ‘probably work’?

Just a mistake but I'm glad I asked on here otherwise I would have gone with their advice to just use it and may have had issues when I fit the bonnet back on.

Strange i've used the higher mount on Carb on the 3 different +2s i've owned no problem.
On my Sprint the higher mount is definitely needed on the Carb side.

Interesting, I'll still be fitting the correct one but just shows you there isn't always a definitive answer.
