One poly engine mount?
One poly engine mount? I've had LT's on my car for 3 years with no issues, but since I installed a cam the drivers side header now sometimes rubs the k member due to the engine shaking at idle. I was going to pull the d/s header off to grind down where it rubs and touch up the place on the header where the coating wore off. I was thinking that while I had the header out I would replace the d/s motor mount with a Prothane poly piece, but really don't want to pull the pass. side off too. (#$@%! #8 spark plug!) Would It cause any problems or increase vibration to run just one poly mount?

The passenger side does make a difference but some might get away with only doing one side. I did the driver's side first and my Y still hit just not quite as often. So I did the passenger side and it seems to have made the difference.
I started doing my motor mounts and by the time I was done with the driver's side I was pissed off enough that I said screw the other one. I only did it to stop my exhaust from banging and the one mount did that.
um y would that make a difference? r u saying the engine turns the other way in reverse... 
The driver side of the engine tries to come up under acceleration and the passenger side presses down. The weight of the engine already has the passenger side pressed down so yes, the driver side mount does the most to control engine movement.
Do it right the first time and swap out both mounts. It is a PITA, but thats the price we pay for our cars.
...and WTF is this about reverse and the passangers side motor mount?
My god, the crap that turns up on here sometimes!
