I have a '91 Camaro with a 305 TPI engine which appears to be tilted to the passenger side when viewed from below (ie trans pan vs. crossmember). I know that when measured at the plenum, a straight edge across the shock towers will show that the passenger side is lower than the drivers side. Is this carried throughout the engine, beyond the intake?

I'm trying to have a vibration diagnosed and the mechanic is uneasy about the fact that the passeger side of the motor sits lower than the drivers side. He wants to replace the motor mount, but I don't think it is neccessary.

If the mount bracket is hitting the frame....??? Vibration..??
Motor lower on one side...? Never mind.

 

How much lower does it sit?

 

Kinda depends on where you take your referense points. Across the trans pan with reference to the tailshaft crossmember, it maybe has 3/4" difference.

Matt,

Motormount would be the first guess, assuming the suspesion is not tweaked. If the "tilt" is visable, then most definitley it should be checked....the mech should be able to pry up in the MM area and see if the the rubber is shot on the mounts or not.

My guess is you don't want to pay for the MM replacement? Lotta labor involved for a 12 dollar part, but neccessary. There may be a tech article on it, if you're handy, invloves removing the lower arm to gain access, IIRC.

 

you don't have to remove the A-arm i heard....just alot of swearing and throwing of the tools..lol

 

The passenger side motor mount usually wears out or gets crushed quicker than the driver side mount.

Camaro6spd is right though......I've done my passenger side mount, and it includes lots of swearing.

 

Not as much swearing if you remove the control arms. I had to anyway because I was installing ES control arm bushings at the same time. Might as well, right?
