1994 E420 ,Coolant going down,no leak
 

I have looked all over,and fixed all the leaks i can find.Do the intakes on these cars leak into cylinders or am i looking at a bad head/gasket.
There are no leaks at any normal spot.I have dye in system.Not heater core ect...
Getting desperate.Used to leak one cup coolant a week now per day
:confused:
Thanks

Sure sounds like it, getting misfires? Have you had it over heat? I thought MB had gotten that figured out around 92-93, maybe not.

Thats the problem,no misfire,runs at the perfect temp,no oil in the water bottle.Just coolant loss

Its possible its leaking into the exhaust. If you didnt top it off you would eventually have a problem yes? Same symptoms on my 740i, we kept adding fluid until it let go. Then is misfired. :D
