Re: [MBZ] 2.5T, delivery valve seals leaking, low power?
This thing doesnt smoke at all. I checked the ALDA line, but will check it again. Not sure what the EGR is doing. I do know I had several codes set in the computer when I checked it a few weeks ago. I will check them again and see what they were exactly. --- Kaleb C.

No smoke with bad knocking at idle, smooth above 1500 rpm and low power is the set of symptoms on my 300D that was cured by new delivery valve seals. Bad head gasket didn't help any there, either. No smoke, low power, and sluggish throttle reponse at low speeds can be plugged fuel filters -- just replaced mine, what a difference!

Re: [MBZ] 2.5T, delivery valve seals leaking, low power?
When mine were leaking, they left a mess on top of the IP, left a distinct Diesel odor as you walked by the car, and it required significantly more cranking to start in the AM. I didn't notice any change in power after replacing them on either the 603 or the 602 engine. -- OK Don, KD5NRO Norman, OK There are three kinds of lies: lies, damn lies, and statistics. -Benjamin Disraeli '90 300D, '87 300SDL, '81 240D, '78 450SLC, '97 Ply Grand Voyager ___ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] 2.5T, delivery valve seals leaking, low power?
Well, I check the alda line, it seems fine. On this car is a little different than the 91. It comes out of the intake, goes to a Y, one of the Y's go to the ALDA, the other Y goes to a pressure sensor by the battery. Does not have the cutoff switch in between. I pulled the codes and it had one for EGR actuator/transducer something or other, one for rack position sensor, and one for starter ring gear sensor. Cleared the code for EGR, but no matter what I did I couldnt get the other 2 to clear, even after unhooking the battery for a while. I also noticed while idling, if you run the engine ad various RPM, the flap deal on the turbo outlet never moved at all. On any other 2.5 I have seen, it seems to move back and forth at various times if you rev it up and/or down while sitting there. No code set for that but something doesnt seem right. I do know when my other one I had, if you had any sort of vacuum leak you had zero power. I suspect there is a leak somewhere. Anybody know how to test all those switchover valves, and vacuum transducers/actuators whatever they are over on the passenger side?

Re: [MBZ] 2.5T, delivery valve seals leaking, low power?
Kaleb: Pull a vaccum on the supply line. If it won't hold, the transducer is toast. I'd replace both of them, it's been known to fix the problem right up (or all three -- EGR, flap, and turbo boost control). If any one of the three is bad, the computer goes to limp mode, self explanatory. Peter On Aug 4, 2007, at 5:43 PM, Kaleb C. Striplin wrote: Well, I check the alda line, it seems fine.

Re: [MBZ] 2.5T, delivery valve seals leaking, low power?
Check the turbo and the waste gate control (electronic? If so, the transducer is likely bad, no boost!) Make sure you have good fuel delivery to the IP, too -- the hoses on the suction side can crack and leak air in -- lotsa knock and lousy power.
