A mechanic ran the pcv to the external bowl vent

[1968 Charger]

The mechanic that installed my intake and carb ran the hose from the pcv valve into the external bowl vent.
He put a rubber cap on the pcv valve of the carb.
I assume I need to run the hose from the pcv on the valve cover to the pcv valve on the carb.
Do I just leave the external bowl vent open. (what does this vent do)
I'm also putting a Mopar breather cap in drivers side valve cover because he had it capped off.

Any help would be appreciated, comments, suggestions.

That PVC hose needs to be attached where there is vacuum. Not on that bowl vent. You can leave that bowl vent open. It's an old smog connection for fuel vapor that was routed to a canister on the firewall years ago, in another galaxy! HA HA

I am assuming he is your EX-mechanic?

One of those cheerios box graduates!

Well to be fair , the guy probably has never seen a car with a carburetor. now a days it's like taking your car in to Midas and having them try to dial in a six pack

It vents the fuel bowl to atmosphere. Did you two come out of the same box of cheerios? Lol. Just messing with you. Where did you find this guy? I tend to give the benefit of the doubt to young guys seeing as how cars haven't come with carburetors in over 20plus whatever years. A lot of newer cars dont even have pcv valves. They now have elaborate crank case ventilation systems built into the valve covers. Whoever it was needs to ask someone next time

I'm thinking this is why I had an oil pan gasket leak, I had no crankcase ventilation.
Now when I run the pcv hose to the front of the carb and have a breather on the drivers side it should be fine.

I hate to say it, but I'm about to put the fourth oil pan gasket on.
I have already taken everything apart (steering linkage, oil drain, oil filter, headers, starter) three times in the last month and every time I start the car there is an oil leak.(taken apart three times, put back together twice, the last one using rtv just squished out)
I was using the cork gaskets, but now I'm going to use a FEL PRO rubber coated fiber gasket.
I think crankcase pressure might have been the problem.

Run a hose down away from the engine. Just in case your needle valve screws up all that raw gas will dump on the ground instead of your engine

Where is it leaking from the oil pan? Possibly from the timing chain cover to oil pan attachment? By chance?

Wonder why they don't dump it into the carb like the Holleys, seams safer to me. Sounds like your doing the right think as far as venting goes ( air in one side and out the other).

No raw gas, only a vent. There is very little if anything that serves any function there. The Important thing there
'Is the carb Vacuum pulls excess oil/combustion fumes from the engine, and burns it up back in the engine..Imagine a 67 GTX with a vent on the top of the carb, which it has. That year, it vents to the atmosphere. In 1970 and newer, it goes to a canister. that is all there is to it.

The bowl vent on my 71 goes into the valve cover breather, with the idea that the engine acts as the canister, 70 should be the same. 1972 model year changed to the canister system

No, everything is good up front, the leaks are on the passenger side, first one at fourth bolt from the back and the other two around 2nd bolt from the back.

It was designed to hook up to a carbon canister.

almost sounds like a fuel pump is leaking oil out the spit hole or gasket is bad

I wouldn't run a open hose on that external vent. It will pull a dirt in to the carb. you can hook it up to the airfilter or just cap it off,if the carb has the vents open on top of the carb. That external vent was for cars with the vapor canister. You may want to look and see if you valve covers have the baffles installed too. Good to see the CS carter in use.

Sorry 68Charger....

LET THIS BE A LESSON TO YOU

WORK ON YOUR OWN CAR

 

[rumblefish360]

That vent should be left open! No cap! Just left open. No hose on it. It doesn't suck in anything. It vents (outwards) fuel vapor. Run that hose from the PCV to the front of the carb.

Fire the mechanic

did he do the wiring on the firewall too? looks like a barn burner waiting to happen, or the engine bay is wired for speakers...
