94 v6 vacuum question

Hello, Maybe y'all can help me with this hose.

It looks like something is supposed to go on the end of this tee on the hose coming off of the intake running to the driver side valve cover.

it was taped up by the previous owner.

I think it maybe causing a vacuum leak.

I just used a piece of rubber hose to replace it. I am pretty sure its something like a vent for the motor. I'd have to look on my car to make sure, but I think that's what it is.

Re: 94 v6 vacuum question

I suspect it is causing me a hesitation problem.

When I give it throttle from idle there is a slight hesitation before it revs.

I have had the car one week, it was running pretty rough when I got it.

The previous owner said a friend of his who builds race Mustangs had rebuilt the motor 10k miles ago.

From the looks of the visible gaskets he appears to be telling the truth.

So far I have cleaned MAF, throttle body, EGR, IAC, replaced air filter, fuel filter and ran sea foam through.

It is running tons better but still the small problem.

Re: 94 v6 vacuum question

Thats supposed to be just one line running over to the valve cover so plug it up(the top part that has tape on it) correctly. It works in conjunction with the pcv valve. The pcv valve is sucking vapors from one valve cover and that one (you asked about) aids in circulation by being connected from the other valve cover to the intake. That line doesn't have any recognizable pressure on it while the engine is running but it does go from the valve cover grommet directly over to the intake. That fitting is not OEM, it should just be a 90 degree elbow.
