Not real clear that the new mounts are torn? Those ripples on the sides of the rubber are common. What would be a real concern is a tear through the soft black material.
The shaking side to side is either (1) a bit of crap got into an injector, or (2) you over adjusted the rack damber bolt. If the latter was the case, you will notice the engine will shake or will act up after running it up and letting off the throttle. If it is seriously over adjusted it will die with the same run up.
Maybe just follow up the work with a diesel purge session.

I Don't know if it helped, but right after I adjusted the rack dampner, I poured a bottle of Redline's diesel catalyst. Would that help? Moreover, I have a new Rack dampner bolt coming by mail. I'll have to see what that does!

You should get a can of diesel purge and follow the directions carefully. Basically you run it full strength through the fuel filler and into the IP, with the fuel return line running back into the container, until the entire can has been used. I do this once a year with both of mine and they always show substantial improvement after the purge. Just using fuel additives is not nearly as effective.
Don't get oversold on that damper bolt. If it is set right and is doing what it is supposed to, that problem is solved, until the bolt gets worn futher. You already said the engine smoothed out when you set it. That is a very good result. There are a host of other things that will make these old diesels shake and so on. Just solve one at a time.

Sounds like really good advise to me. Thanks!! Would you recommend a good brand of diesel purge. I've never done this before so any recommendations will be great!

Diesel Purge is the brand. Go on google and you should be able to find it as cheap as about $6 a can.

I think he might be referring to "Diesel Purge," from LubroMoly. I ordered some recently from E.T.Y. Parts, based on a suggestion from someone else on the forum (sorry, I don't have the time to search so as to give him credit). I paid $7 per can for a quantity of 5 cans, and shipping seemed reasonable.

Search the forum on "diesel purge", and you'll find plenty.

Thanks to all of you who have chimmed in! I'll try that purge as soon as I find it! Again thanks for all your comments

He fellas, just wanted to chime in here and tell you all where I am at (maybe this will help someone else). I took your advise (of doing a diesel purge) and placed it on hold until I finally recieved the rack dampner bolt I ordered from Performance Products. Well I finally got in today, and installed in the IP. At first I didn't know how far to go with it, so I just screwed it in until I felt some resistance. I acclerated and let the accelerator go, to see if it stumbuled, but it didn't so I left it there. I tightened the Lock bolt and went for a drive with my wrenches in hand. WOW What an improvement. I would have never imagined a stupid little bolt would be responsible for so much "sea-sickness". Anyway, I am planning on running the Diesel Purge, but I have to find a retailer round town that carries it. I have 2 questions though. 1. Did I tightened the bolt too much?? and 2. How do you actully run the purge through the system? I read a couple of threads that say that just pouring it into the filter will only send it back to the tank. So how is this done???

Again thats for all your input! Couldnt have done it without you
