Misab plates
Posted: Tue May 08, 2018 9:51 am
I fitted some of these 4 years ago in place of the original alloy spacers with O rings.
I was surpised to find that they are quite badly cracked and degraded after only 11k miles. I was going to go back to the O rings and spacers but I could readily obtain Misab plates and they were cheap so what the hell!
Question - do I still need flexible mouting of the nuts with these or can I bolt them straight on, the assumption being that the Misab plate design provides all of the required 'flex' / anti foaming effect (which I've also heard tell is a myth)?
It was interesting tighetning them up (re using the rubber diablo mounts) to hear the engine note change when they were tightened further which made me think that thye need to be quite tight in order to form a proper seal.
Any observations welcomed
