Going to confront mechanic - what causes wicked engine vibration *only* at 4k rpm?

I think my engine was slightly out of time when I first got the car...smoothness increased across the operating range with a re-timing. It wasn't like I eliminated one resonance at one engine speed. Worth looking into, though.
FWIW, my 83 did not have the U stamped into the sprockets, so they were replaced. It may not be unrealistic to assume that someone changed the sprockets on really early cars.

My car didn't have the U's. I doubt yours does unless someone in the past changed them...but your car is a low mileage car so you'd probably have records of that at least.

I live in an apartment complex, so no real time or space, though I am almost ready to debut my backup car to DD status... ugh...
I am in the North Wales/Philadelphia/King of Prussia area... would love to find a fellow rennlister to look at it...

^ Just don't pay attention to the U's ^

I have a playdate on Thursday with a fellow lister. I don't want to bring my car back to said shop anymore... I'm probably fixing my door handles myself tonight... oy. =) But very very grateful for all the help.

No problem. These cars really aren't that beastly to work on.

I am sure Thursday will be a very good day for me. =)
Right now the 944 is my DD and I sold my backup car (my supposed, DD). I have something else in the wings but I am driving it back on Saturday, then it needs inspection/registration...
Saturday = Oil, trans fluid, brake flush, rad support replacement, to name a few, on the replacement (and official) DD. Those are things I can do without too much trouble.

Lower Balance Shaft Pulley Was Not Installed Correctly By Dinardo Foreign Motors... Stay away!
Big props to RS Barn for the assist!
Found some other niggly things that have been addressed (a few more to do myself but they are easy (cap, rotor, air filter, wires, spark plugs, finish vacuum lines, and clean grounds), to start. =)![thumbup](https://rennlist.com/forums/graemlins/thumbup.gif)
