I purchased a chrome kit for our 66 Coupe. Right now each valve cover has two holes, one(driver side front) holds the Oil breather cap and the other in the back of the motor on the passenger side of the engine. I am not sure where it goes to. It ends up to the thing behind the carburator. (Sorry I am not very mechanical nor familar with the car parts. As you can tell) I called the place that I bought the kit from and they said that they have included 2 PCV plug. I should cut one to fit around the breather cap and I need to completely plug the other hole in the valve cover (The one on the passenger side).
If I plug the hole on the valve cover, what do I do to the other end of the hose? I can't just leave it hanging. Where does that hose lead to and what is it called, EGR valve (Behind the carburator)?
BTW the kit came with no instruction what so ever. I have a feeling that I'll be bugging you alot.. Sorry

Thanks In advance.

The way it's supposed to work is fresh air is drawn in thru the breather on the drivers side,
circulate thru the engine to rid it of fumes etc, then be drawn out thru the pcv valve, positive
crankcase ventilation, thru the hose you spoke of and into the carb base where it gets burnt
in the cylinders. Can't quite figure out how they told you to rig it up. Did they give you a hose
to go from the one on the drivers side to the carb base? And no you can't just leave the old
hose hang, major vacum leak.

You should do a search on the PCV system. It has been discussed a couple of times before, and there were a lot of good posts regarding the setup.

Anyway, heres a short version of it. The way I got the set up on my 66 Hardtop, and I think it should work.
Of course there are other ways to set it up as well, so as mentioned above, do a search on the forum... . /forums/images/icons/wink.gif

I have 2 holes in each valve cover as well.
Both front holes are plugged with oil filler caps, while the one on the back hole on the drivers side has a breather cap with a hose which runs into the aircleaner (ingoing air).
Of course there are different styles of breathers, that dont require a hose that runs into the aircleaner.
But that is what the PO installed and I kept it that way so far.

The back hole on the passengers side has a PCV valve, and the hose of the valve is going into the PCV port of my carb (outgoing fumes/air).

Bottom line, as far as I recall is, that the drivers side should always have a breather for the ingoing air.
The passenger side (back) should have the PCV valve for the outgoing air/fumes.
Thats the basics of the PCV system.

Im afraid that my knowledge on that is a bit weak, but I guess the facts are right.
If Im wrong though, please correct me... . /forums/images/icons/smile.gif

Exactly. That's what I thought. They told me that I should just plug the one on the passenger side that goes to the carb base. No, they did not give me a hose. Just two plugs, Two valve cover, 12 Wing Nuts, One oil Breather and Chrome airfilter.

My original air filter has two hose coming to it. One from the oil breather cap and one from the same unit you mentioned (Carb Base). The one from the breather cap os no longer used. That is fine. Then what should I do with the other one?

Thanks for your explanation. I will do a search as well.

Don't believe that will work with just one oil breather, blowby will force an oil mist out
of that breather all over your shiny new covers. What brand is it anyway? Just so I
knows to stay away from them.

If you have two holes in your airfilter housing, which arent used anymore, you should plug them I think.
Otherwise there might be the possibility of getting dirt into your carb/engine thru these holes.

Again, theres only one hole/plug on my airfilter housing, and its connected to the breather cap (driver side-rear hole).

This is the kit that I ordered:
http://www.cal-mustang.com/cm_able/showdetl.cfm?&DID=7&Product_ID=3164&CATID=19&CM_SA=1

I hope that shows up.

I will remove the original air filter housing and replace it with the one piece chrome airfilter. The breather hose is eliminated, but the one that goes to the back of the air filter remains. I don't know what to do with that one.
Also if plug the PCV outlet from the Valve Cover (Which I will not), then the lower carb will have two hoses sticking out of it that no longer go anywhere. One that was going to the intake housing, and one that came from the valve cover on the passenger side.

I think that it is time to gove the folks at CalMustang another call. I have already called twice and they have said the same thing twice. "Plug the outlet and the hoses." Unless I mis understood them.

First of all, you are not bugging us.When you ask a question, it is because you need help...And, there probably more people out there that are interested in solving the same problem.
Passenger side hole in valve cover(should be at rear of motor) gets the PVC valve. Install the small rubber gromet, then put the PVC valve in. Now, use the original, bent hose to run to the back of the carb. base.
Now, for the driver side. You can do this a few different ways.
#1 way: put breather cap with hose connection in. Hook hose to bottom of the breather.
#2: Go to your local auto parts house. They sell a chromed oil cap that has no hose outlet on it at all. Install this one, and block off the hole in the breather.
Also, look at your breather without the top cover on it. Where is the hole for the hose? If it is on the outside of the filter, you don't have to plug it. If it is inside the element, it must be plugged. If the air commong in is filtered, the hole came be left alone...

Thank you.
I ran a search last night and read many many posts.
Your Option number 2 is the route that I'll be taking. The kit that I bought comes with the Oil Breather cap that is closed (The one without a hose coming off of it).
I will be replacing the Aitfilter all together and replace it with an aftermarket one piece air filter. This will work good if I eliminate the hose coming off of the oil breather cap/filler. If I researched correctly, I will need to punch out a hole in the aftermarket Air filter and connect the hose that is coming from the base of carb to it. This is one of the hoses that was going to the back of the airfilter housing and had it's own filter. Therefore, I assume that it is okay for this not be filtered.

Thanks in advance for all your help.
