Intake bridging hose on R16
Hey all... going through the 67.5 1600 I picked up at auction... engine bay is a mess, slowly starting on fixing it.
Re-routed the fuel lines correctly and pulled off the plastic split loom someone had wrapped them with
Replacing the old cracked throttle cable that continually sticks, despite the homebrew 'return springs'. Ross from Sports Imports is express shipping another one (so good to live in Canadia )
However, looking at the intake manifold, someone has bridged a hose between the two runners:
Car seems to start, idle and run fine despite this. Should I pull and plug the intake runners or just leave the weird hose there... looks fugly.
Thanks,

Re: Intake bridging hose on R16
Both my high windshield cars have plugs in the intake where your bridge hose connects.
I'd remove the hose and plug the holes. You're right, it's ugly.

The zip ties do not add much either
Plugs are easy

Re: Intake bridging hose on R16
totally useless. The large casting between the runners is hollow. The manifold is already bridged.

Re: Intake bridging hose on R16
There is already a balance tube cast into the intake manifold so that hose is not only ugly but superfluous.

Re: Intake bridging hose on R16
supposedly those holes are for balancing air flow - since they exist on pre-smog cars - never found anyone who uses them effectively - KeithoLan??

Re: Intake bridging hose on R16
You can use them to connect a vacuum gauge to each of the runners for tuning purposes. I tried it and it does work. You can adjust the two carbs to the same reading quite easily. Ultimately, a digital EGO gauge is the beez neez

Re: Intake bridging hose on R16
How would you get a good vacuum reading from those holes when the bridge in the manifold connects them?

Re: Intake bridging hose on R16
Loose the hose. The balance tube in the manifold is more than adequate. In the early cars that is actually a casting hole plugged with a screw in plug. On the later ones they used it for emission stuff. The hose is: in the way, looks ugly, a problem when it fails, not needed.
