Can't explain why but my polyurethane puck style engine mounts imploded!

My car has been in storage for a little over a year with short drives every 2 or 3 months. Today I decided to install a starter booster relay and when I looked under the car one of the engine mount bolts was missing and the other is sticking out about an inch at a weird angle. Upon inspection, i found bits and pieces of the engine mounts inside the subframe.

I didn't have any vibrations or weird sounds or anything to make me think something was wrong. From the top the engine looks ok, I don't know what's holding it in place...

So now to replace them! Any idea what caused this?

 

Surprised no one has chimed in on this. But AFAIK, that isn't common. Had Noltecs for a number of years. I think they may have settled a mm or so, but nothing even remotely looking like that. Who made them?

 

+ heat maybe? My exhaust side mount didn't look too happy recently (wish I had a pic). Same color, did you use McMaster Poly? Mine was more of the melted look. I guess heat could cause stress & vibration cause it to chip apart

 

Wow, thats not good!

 

Not all upgrades are an upgrade.

 

Hmmmm, I crawled under the car last night to take a look after seeing this thread.

Everything looks the same as the day I installed them 4 years ago.

Who made those mounts?

 

can oil + heat cause this? my car has a minor oil leak right by the mounts so everything back there has a dirty layer of oil on it.

I bought them from a forum member, I think he custom made them from mcmaster polyurethane. They've been in the car since summer 2009.

I'm going to be using IRP mounts now.

 

My IR Performance mounts look the exact same as the day I installed them. Good catch, and glad you caught it early. A hard pull and you could have bent the PPF with mounts in that condition.

 

I had a set from a group buy years ago. I sent in my 94 set with heat sheild and got back a 93 without a heat sheild. They crumbled in to peices when I removed engine. Only a few thousand miles on them. The missing heat sheild could be just as much of a factor as the material they used.

 

pass side on left, drivers on right.

that's all that was left.

I realized the engine was lower and the ac pulley was rubbing on the ac line under it. An I had driven it nearly 300 miles like this!!

 

Holy ****, thats bad, i guess stock mounts aint that bad ...
