Default What damage can bad motor mounts do?

The motor mounts on the turbo are shot (per the PPI my dad had when he bought it). I'm debating getting them fixed, but may not be able to for a while. I know to go with OEM instead of aftermarket, because they last longer, but what can happen if I don't fix it? any major damage? thanks!

Keep an eye on your fuel rail.

More vibration is never good. Fatigues stuff.

If left long enough a really bad vibration can contribute to the dreaded oil pick-up tube crack and will accelerate cracking of the 951 headers. Bad PO but at least he was up front and told you.

I heard if its really bad you can start to ruin your crank bearings toward the end of the block. Please do not quote me on that i was just told that

-oil tube cracking
-trans mounts will go quicker
-ive seen stuff rattling loose like airboxes/vac lines
-fuel rail leaks
-header/exhaust fatigue
-let it go long enough you could have other problems as well...

When I bought mine the driver's side mount had collapsed such that the turbo water pump and the throttle-return spring were resting against the brake reservoir shield. Maybe mine was just extreme, but that can't be good.

One of the heat shields on the cat had also vibrated loose, possibly due to the abnormal vibrations of the system.

Anyway, after having them replaced the car was soooo much smooother. It was like a whole new car
