Will leaking delivery valve seals on a 2.5t cause low power? I have one that
has 240D like performance at times it seems, has bad leaking seals, but runs
great. Will the leaks cause lower power or should I look elsewhere? Yes, I
will be replacing the seals anyway

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.

Norman,
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

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.
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.

I can't really
Wonder how much them things are. Maybe I should try some used ones first.
