My Deal With Chevy
As some of you may remember I put a standard 350 chevy engine in my mother's 95 suburban with myself and my mechanic. Well it's a fabulous 500 miles later and there is a vibration coming from the engine I believe. We changed over 3,000 dollars worth of parts/sensors/gaskets/wires/etc. on the overall rebuild.... but still the vibration came. So today I took it down to the dealer and told them that my mechanic and I believe there is a vibration in the engine and I showed them how it felt. The service director believed there was a vibration but wasn't yet convinced it was from the engine. So he said that they would look it over free of charge and find the vibration and if it is truly coming from the engine. ....More drama will come when I call them tommorow and find out the results. So yeah...just random bickering.

Well chevy said that during the install that I should have changed the engine mounts and that is what is causing the vibration. I think that sounds like a legitimate reason. My problem is that it only gives off the vibration when the car is in gear @ idle. But the RPM are holding @ about 6k which is normal for a suburban. Your thoughts?

First, I want to make sure "...in gear @ idle" means what I think it means: Car is on, it's in Drive, one, two, etc, (the "in gear" part) but you have the break on (the "idle" part) so you aren't actually moving.
So you only feel the vibrations when the car is in gear and idling (meaning you have the break on and aren't moving) and you feel it, then I take it that you don't feel the vibration when you left off the break and start moving? If so, that to me would make sense. Unless it's vibrating like crazy, would you really feel it over road/terrain vibration?

Good luck with however you end up going about getting this problem resolved.

Not sure how suburban motor mounts are but they shouldn't be that tough. jack under the motor to support the weight and a couple of bolts to drop out the old ones and replace with new ones. A large crowbar for the required gentle persuasion to line up bolt holes.. BUT the Burbs might be different. If you replaced the whole engine, I'm sure you From the write up, def sounds like they could be the problem. Are they rubber/poly cushions or are they hydraulic. My pops had a special service Taurus that exhibited similar problems and it was the special hydraulic motor mounts that were $800 to replace.
