1978 450SL Vacuum line question - Problem solved
Hello all, new to the forum. I just got done replacing and re-routing the vaccuum lines on my car. The previous owner's mechanic had them routed wrong and they were cracking and brittle.
After getting everything hooked up their was a lone line coming off the crankcase breather hose that goes from the passenger cylinder bank (1-4) to the air filter assembly, photo attached.
I looked through the vaccuum diagram thread and through my manual but can't find where this goes or even if it goes anywhere. Any assistance would be greatly appreciated.
