This 603 engine doesn't sound good to me...

[Chris_87_300D]

Please see (listen to) the attached PDF which contains a sound file of my 603 engine (1987 300d turbo).

I recently had the injectors rebuilt - first time ever after around 335k miles (unless it was done in the first 50k before I have records). The injectors were at the very bottom of the pressure range spec (all between 133-135 bar) - they were set after rebuild at the mid of the factory range (142 bar +/- 2 bar). I also adjusted the alda as per the many other threads.

The thing drives like a champ - seems to have more power, a bit quicker, etc. but, it sounds very noisy vs. what I recall before my "upgrade". It also smokes a little just sitting at idle which I don't recall seeing before and runs a little rough (sitting in the cabin).

I'd appreciate hearing some comments about the sound - I can live with it if it's not the sound of something wrong or going wrong...
