Hello everyone, this is my first post on this forum....hurrahh!
Please go easy on me as I pick up the correct terminology!
I am delighted to reveal that my car is A '67 Coronet recently sold to me by the ever helpful MCI. After my Dad and I do the floor pans and a few bits and bobs, she'll be ready to m.o.t.
We were a bit puzzled though by the use of an extra hose, going to the servo from the rocker cover breather....surely it only requires the vacuum hose from the inlet manifold??
Not a drastic first post but I was dying to ask something so please help!!!
Cheers
Steve

Welcome to the board mate. Be prepared to get inudated with replies that firstly we need piccies of your car.
As far as your query goes, the servo on my charger had two outlets, one to the inlet and the other blanked off. I would say the connection to the rocker cover is wrong.
No doubt someone will come back with more info.
Anyway, lets see ya mota then mate

Welcome.
The servo should be connected to the intake. Any other connections on the servo should be either blanked off or used as a manifold vacuum source or anything that needs it.
The drivers side rocker cover should have a PCV valve in it and this connects with a hose to the base of the carb (manifold vacuum). This draws crankcase fumes/pressure out of the block.
The passenger side rocker cover should have a breather connected to the air filter base so that clean filtered air is drawn into the rocker cover via a larger diameter hose.
Some cars came with the breather and PCV valve on opposite sides. This works but as oil is thrown up to the passenger side from the crank it is better to do it the way I suggested so that oil is not sucked into the carb.

Thanks guys.....thats it sorted then!!
I'd loooovveee to put a picture or two up... I only got the car delivered on Friday and its up on stands at the mo.
I have one or two from MCI's website, I'll stick those on for now.
Oh, by the way this is a little off topic but would anyone know how to get hold of bulb holders for the rear lights of the Coronet?
