2nd Gen R56 Cooper S Most liked posts in thread: My engine and tranny bouncing around under my hood?

Where are the 3 engine mounts located?

 

Below is a plastic connector that rests directly about where all of the marks are on the airbox, they line up perfectly! If it weren't for this plastic connector I fear that my hood would have been dented if it came into contact with something less flexible.

I couldn't move my engine from side to side or push it towards the rear firewall, but I was able to pull the engine in an upwards/forward motion. I pulled from behind the valve cover and in-between the stock airbox to get the engine to move only in an upwards/forward motion.

So it seems as if the number #5 mount at the bottom of the engine is the weak link, now I have heard of some who have replaced this particular engine mount that caused pretty strong vibrations. I want something a bit firmer than stock but not crazy stiff if you know what I mean.

I have heard some mention that they get if very stiff for performance for track use, what are my options here and are there a lot to choose from that all vary in how firm these engine mounts come in?

Thanks,
Systemlord.

 

I forgot to mention that on the left mount (passenger side), all of the bolts have wear marks from probably serious torque was applied to them . Let me see if I understand the mount with the #1, #2 and #3 is all one mount? The motor mounts to the chassis while the other two (upper and bottom) are above and below the engine? If so I don't understand what part needs replacement...?

Are there only two motor mounts?

 

I have a 6-year/150k warranty starting this past March and it's a 2007 MCS. The engine mount on the passenger side is very stiff, my engine is bouncing up and down. Why would I need mount #1, #2 and #3 mount? No matter how much I try to get the passenger motor mount to move, it's like a rock.

 

I being they have to remove the engine to check the motor mounts? I also believe that my HPFP is signaling it's demise, I'll have them both looked at also. Is changing either of the three motor mounts time consuming (more than 4 hours)?

 

I think I'll wait until my gas pump takes a dump, keep it under one $200 deductible. I have been hearing a progressively louder sound right where the gas tank is located under the car, sounds like a rusted shaft spinning fast with bad ball bearings, sometimes the sound comes and goes throughout the day. This could be why my engine runs lean sometimes causing a periodic ping on hard acceleration, you think?
