Obviously, with the new eng side mount, there are no cuts like the used tired one.






And because of the way this mount is holding the engine, you will notice significant drop in eng position once the mount gets tired.
Even without any load, the eng mount holder is about 8mm off so once installed, probably more than 10mm drop.
Not good….




No wonder why I didn’t see big movement when I removed the mount.



I saw several aftermarket mounts design but without knowing the correct geometry and how the eng/gbox are mounted against the sub frame and chassis frame, not much point in using them.



All four mount bolt/nut loosened and waiting to be tightened in the specific sequences.



Keep cleaning the mating surface of the valve cover gasket…… So much oil and why so much black liquid gasket…..

    Hello Kaz,


    Do you know if there is a technical reason why the alternator bracket + right engine mount are made of cast iron?


    Other than this bracket being the anchor point for lifting the engine for maintenance i can't figure why would this part need to be made of cast iron... Also i could be wrong, but it looks to me that this upper engine mount is not the one suffering the most...


    There is an aftermarket option to have this bracket + mount made of billet alluminium, so for me it would be a nice place to shave some weight and lower the CG (upper part of the engine), all i would have to do is go with the original bracket when i need to lift the engine for maintenance.


    I do know that Honda could not have this kind of compromise... but I was wondering if there is any other technical reason...


    Thanks
