Motor Mount melted

[mtroxel]

Last oil change I saw some melted grey stuff on the belly pan. Followed it up to the driver's side motor mount. Thought it was just leaking, but it turns out the grey neoprene bonnet that covers it had melted. Obviously this is about 1" from the bottom of the turbo. All factory heat shields in place.

Anyone seen this? If I put a new one on, I would think that one would melt too.

Dude for it to get that hot, you should be looking for issues related to the heat. Are you sure they're neoprene, it generally wont melt but ignite at around 500F.

Maybe it fully collapsed and a peice of the mount rubber was against something hot??

Shameless plug, I have some brand new 034 motor mounts for sale :)

Maybe your turbo is getting that hot? Beat the out of it before it happened? The turbos can pretty easily glow red hot (thats about 500f) when being driven hard, that could heat that up pretty good if you get it hot enough. I feel like that's scary hot to do that though. I'd be worried about the life of the turbo at this/that point

No I'm not sure at all. It was just my way of describing it.

I don't see anything touching the mount at all. Nothing looks weird there at all. Heat shields are all fine.

I'm wondering. I did a APR Stage 1 in June. I drove it hard for a few weeks just to feel the extra power. But I've also had a lot of "boost control range not reached" since the Stage 1. That means I've been doing WOT runs to log my boost. And when I graph those runs, I'm usually a good 1 1/2 PSI under the boost request as shown below. I've read that underboost codes can mean the turbo is always spinning faster than it should to try to make the ECU happy. That's my current theory.

How much? Why aren't you instilling them?
