A few things I found out tonight working on the Insight.
There is not an inspection panel to check the crankshaft end play. The oil pan would have to come off. The oil pan is clear of any obstructions, but it has the oil filter and something else attached to it. Decisions, decisions.
Here is the rear motor mount from my MT Insight. The mount is pictured just like it sits in the car. The broken leg points toward the front of the car, the good leg towards the rear, and the short leg points upward. The lower right leg is cracked clear through. Both lower legs are compressed when the car is in any forward drive gear. That means the lower legs are stretched when in reverse. With a broken leg the motor mount will not dampen the engine when in reverse. I was thinking of taking some of that Urethane window caulking called 3M Window Weld and gluing the broken leg back into place, but more importantly adding a bridge from the top leg to the inner ring. That will help the reverse gear chatter and help hold the broken leg in compression and hopefully make it a bit more stable. A new mount is about $80-$100USD. So a tube of Urethane and some time is a good trade off. The motor and trans are balanced well so that the rear mount being removed does not require anything to hold the motor in place.
