1971 2,2 T Oil discharge pipe from air intake question
Hello,
i have a question which i would like to introduce.
My mechanic (not a Porsche specialist) is servicing a long time 2,2 T matching number car that was left unusued for years.
The air filter housing, in the back, has a rubber pipe that goes into a metal pipe that goes under the car, seems to discharge
the oil in excess, and going over the right heat exchanger.
It seems strange to me, and when the car revs high a glass of oil goes from there to the heat exchanger.
My mechanic says probably the car has low compression and the oil goes back for depression.
Could be a bad linkage of the pipe? something like an oil discharge that goes on the heat exchangers seems strange, to me.
I have searched for a scheme of the rear of the air housing but i have not found that linkage and that rubber pipe that goes down.
Any help?? Thanks to everyone from Italy!
