606 Engine Noise Getting Louder @ Idle ? ?
The 1999 210 has recently gotten louder @ idle. Neutral or drive makes no difference. Sounds like the engine/trans is under load, or higher idle. Idle speed is about 550 indicated.
Listening under the hood, no discernable/identifible noise to me, but with a stephscope I am getting a ticking sound near the front of the block. I am wondering if the vac pump is the source. With 250K miles, is this an expected replacement intervial ?? I would perfer to replace, prior to the grenade. Is this a problem with this 606 engine. Second problem with gearshift not returning to Park postion, still working on this, after removing console, shifter module and removing a small "ball-chain" key ring from within.

For the noise, it's probably the mount. Try reverse and see if it gets quieter. My car has gone through 2 sets since I bought it in 2006.
The vacuum pump is a totally different design from the OM603. It's driven by a sliding slot drive, kind of like a universal coupler and the vacuum parts are isolated so they can't get into the cam/IP drive area. After a second read, I may have mis-interpreted your description. Is the ticking the only extra noise you're hearing or is it vibration too?

Kartek,
Are you refering to the engine mounts? I have replaced 60K ago. If the trans mount, I have not replaced, could be the culprit. Drive, Reverse, idle, same thing. I will replace the idler & belt, as the belt looks good, but has 200K on it. I am getting vibration & little louder engine noise, when in passenger comp. Under the hood, I can discern a ticking sound, amplified with the steph. Maybe I am making a mountain out of a molehill, but I have had women passengers who noticed a louder sound w/ vibration at start up & idle.

Drop tension on the spring tensioner and fire it up for a couple of minutes.
If the noise is still present it is not related to the belt or accessoriy devices.
