Strange Power Steering Noise on a W140
1992 W140 300SD (350SD).
WHen I steering at low speed in the morning, it screeches. When hot, it seems to go away. Please help. Thanks. Also, I need a motor mount, because it seems the oil leaks from it, where can I get it for cheap. Thanks.

Sounds like a loose belt....though that car has serpentine.....hmm.
Belt tensioner? Usually a screech is the belt and not the pump, could be the pump though. Suspects: -Belt -Belt tensioner -Pump Itself The mounts engine mounts themselves are fluid filled, is that what you mean for the oil leaking from it? Its a common failure, simply buy a new mount. Click "buy parts" at the top of this page and select your model, or you can call phil with the phone number on that page. Putting it in is probably not a pleasant experience though....

Since that is a serp belt you do not want it to break! When they do they usually take a few hundred bucks worth of other parts with them.
The serp belt failed on my friends 735IL back in highschool. Ripped the radiator hoses right off the radiator! $30 belt+$700 radiator and it was good as new! Sounds like the tensioner is not doing its job. Inspect it and see whats the matter.

Probably not anymore. :-) Any folks, could you check on what this part is ? It looks like a shock on the engine. Would it be the culprit from which the oil came out ? Here is the part number: 604 200 02 14 http://72.14.203.104/search?q=cache:SijNtXixeSAJ:www.speed-autoteile.com/MB.EXP.03-2005.xls+604+200+02+14+mercedes&hl=en&gl=us&ct=clnk&cd=1 Says here that it is a tightener. I check and az autohauz and the picture of the motor mount is nothing similar to what I see.

Their is the engine mount, replace in pairs:

Maybe bring it to a good shop.
