Experts Needed - Engine Vibration - Problem Undetectable...NOW FIXED!!!

[Paul G]

This is a great thread. Having the solution to the problem is a great thing.

BTW in 79 I traded a 73 Sat Sebring Plus for a 4 cyl Vega! Gas mileage was better but that Vega was the worst car I ever owned.

My dad sold his 1970 383 4-speed cuda in 1974 for a used beat up pinto, which he later gave away.

All:

It appears we should start a new thread titled "Regrets! Yes, I've got a Few" to chronicle the multitude of stories by people who traded or sold perfectly good MOPAR's over the years for reasons that now seem foolish.

Hind sight is a wonderful thing but so is the future. For those of us who made foolish decisions concerning the cherished MOPAR's of our past we have the future in which to atone. The best way I know to do that is to restore one of mother MOPAR's past creations. In my case I have lots of guilt! I'm working on my second one!

To paraphrase from a song by Frank Sinatra.... Regrets! Yes, I've got a few but in the end I did it my way!

So straightening out the engine fixed the vibrations?  I found this topic because I noticed my tail stock was also no centred in the floor.  This was when installing the adapter for my new gear vendors tranny.  Did your's bend towards the passenger side?  I called GV tech to ask about this and was told that "all dodges were like this".  I'll try to explain the way I remember it.  Dodge has such a flat drive train that in order to get the 3 degrees or whatever in the dive shaft they have to angle things a little to the side to make up for it.  I had no vibrations before.  I surely would have this time tho, since it is now touching the floor.  I am going to adjust it as per your instructions.

Just wanted to see if anyone else ever heard of this.

i agree with the the above posts. I would also look into the front fan and water pump. Of course when you installed the new damper im sure you would have noticed if the fan bolts were loose. However, we had one car come into our shop that had a bent water pump shaft(at least the tip was bent) that didn't leak any water and was nowhere near noticeable until about 3000 and progressively got worse. Probabbly 1 in a mill but it want cost you anything to check

have you checked spark in all cylinders? Have you used a gas analyzer or wide band? A simple aproach would be a dead cylinder check by pulling the wire off of one plug at a time and noting the rpm drop. no rpm drop = dead cylinder.

personally it sounds like a balance issue, but these are a few easy things to check

Not to change the thread, but.  Iceblue, what a beautiful car you have there.   Nice, real nice.
