Holy motor mounts Batman.

I'm new to this car and the second day I got it I tracked it at TMP. Noticed that the power steering was rubbing against the lower rad hose.

Put a new rad hose in and took it to Mosport a few weeks later. In one of my rarer planning ahead moments I kept the old hose in the back of the car. Wouldn't you know I ate through another hose.

Took the car home and put on a shorter PS belt. A few things always seemed to be "off". Replaced the elec. fan with a stock clutch fan and the bottom of the fan blades were hitting the shrowd. My oil pan seemed to be awfully close to my power steering rack.

.... then I looked at my motor mounts.





Notice in this picture the socket (top nut) and the bottom bolt. They are supposed to be aligned with each other. Once the engine got jacked up the top bolt with plate literally "slid" out of the mount.



The motor had sagged so much when I took the bolts off and jacked the engine up I needed extra lift on that side thus the Camaro jack on extra ramp. LOL.





Is the mount bad or what? Yes, thats the half that was left.


Clearance after.

85 325e with over 300 thousand miles.

All I can saw is damn.

Edit: Actually this explains why the old clutch fan chucked a bunch of blades one day, I thought something just ended up in the engine bay that was not supposed to be there.

seeing this reminded me I was thinking of changing the motor and tran mounts in my car, did you stay with rubber or poly mounts?

Awesome.

When I auto-x'd my E30 I would go through a set in less than a year. Glad I'm done with that.

So many things feel different like the shifter, without the weight of the engine pulling down on the trans. At least an inch more clearance to the rack.

Thats a tough steering rack to hold the weight of the engine on it.

Dave> I have atleast an inch clearance all around the fan blades now. Coolant hoses also seem to have more slack. Amazing what such a simple thing can do.

These were the cheap rubber mounts for $18 a piece. I'm not convinced in anything but a 100% race application anything other than rubber is the way to go. I just don't see a benefit, with a whole lot more drivetrain vibration and noise.

FYI> The mount bolts are torque to yield and should be replaced each time for those of you doing this. They were $1.50 each at the dealer. LOL!

Update> Took the car out for a longer spin. Shifter acts much better no doubt due to the properly aligned trans and engine.

However! Extreme vibration over 70 kms/hr. I had a slight vibration before this is much more.

Looks like I put stress on the center bearing and rubber supports. Glad I'm finally ironing this out now. Bimmerspecialist.com here I come!!!!

Probably need a new driveshaft guibo and CSB. I have a brand new one on my ETA, probably has 100km on it. If I take it out, you can have it for pretty cheap, it's a dealer bought one.. cost me 120 ****ing dollars.
