Engine canting to exhaust side

[Concrete-crusher]

I measured the level with a spirit level app. On my phone and its either 0 or - 1 either way pretty level. Also my mounts are different as described above so correct as far as I know

The Lotus Hi lift mount used on Weber Elans ( not Stromberg Elans or Plus 2) raises the engine by approximately 13 mm on the inlet side that it should be installed on in order for the Weber carbs to clear the footwell as the engine rocks under use. The distance between the mounts is approximately 300 mm. Thus the angle of tilt of the engine is approximately 2.5 degrees. Depending on the state of you mounts your angle in an Elan may vary

Placed side-by-side the difference between the two mounts is apparent, the Lotus (Weber) mount having straight sided mounting flanges and the standard Ford mount being shaped. The mounts in the pic are not new but have never been fitted and the difference in height is approx 10 mm. Once installed in the chassis the mounts are around 240mm apart .. much the same as the overall width of the cam cover .. so with the correct mounts fitted in the correct locations and in good condition a visible slope of around 10mm would seem about right.

Not a Spyder chassis by any chance! They use standard mounts on both sides.

The chassis is a Spider Replacement chassis, which I understood to be a std Lotus chassis but with a new front crossmember, as such I assume the engine mounts are in the standard location.

Yes the Spyder space frame chassis uses standard mounts on both sides but the arms that go to the engine from the mount which is located on the chassis frame are I believe a different length on the Elan to achieve the required tilt as the carbs still need to clear the footwell

Thank you for that reply, but I do wonder if the Replacement chassis, which as I say had a new front crossmember and shock towers fitted, also had the engine mounts changed. This is not a complete new Spyder chassis.

Mike,
I have the same Spyder "remanufactured" chassis as you have where the complete front end is replaced. The engine mount brackets are the same as the original Lotus chassis so you should use the Lotus hi lift mount on the carb side and standard mount on the exhaust side as per original set up. I have a Stromberg engine which uses the same mounts both sides but I had no issues fitting them.

I think you said in your first post that you are reinstalling the engine ... was it sitting at the correct angle before you removed it ? If so and you have just replaced the mounts I would suspect that one or both of those is the culprit.

Thank you for clarifying that, the car came with the engine out, got new mountings as a matter of course and unfortunately the originals were disposed of, so can?t compare, but will try playing with one removed to see which looks correct.

I can confirm that on my Plus 2 with an early Spyder refurbished chassis I have the same mounts as mentioned above by Oldelanman. On my car with this arrangement the engine silts level, and has sufficient clearance between the carbs and the wheel arch. With two standard ford type mounts there was insufficient carb clearance.
