Default Breather smoke

I am new to this forum and new to classic cars. I just picked up a 65 convert. It is coded as a 6 cyl but somewhere along the line a 289 was dropped in. Each of the valve covers has a breather in it and they both smoke quite a bit, enough that the fumes come into the car while driving. Would replacing the breathers help since? Do they have filters in them? Can the smoke be vented out under the engine?

thanks

The recomended setup is a PCV (positive crankcase ventilation) valve on the right hand valve cover with a hose to the base of the carburetor, and an oil breather cap with a hose to the air cleaner on the left hand. Excessive smoke may be a result of the rubber seals on the valve stems in the heads (under the valve covers) being defective.

Most of the chrome is pitted and the weatherstipping around the windows is going to get replaced. I have a new rear window on order. We had some good rain this week and when the previous owner had it painted, the pulled all the body plugs so there is some water leakage through the firewall and floor. Making it water tight is my first priority. After that, a rebuild of the 289 and maybe a disc brake conversion. It is my daily driver and most of the drivers in Indianapolis suck so I would like to have it stop in a reasonable distance.
Not to concerned about keeping it original since that was tainted with the engine replacement.

if your floors are wet make sure that your cowl isn't the culprit. take a pitcher of water and pour it inthe vent near your windshield and wait for a bit to see if any water goes down on to your carpet. if it does, that sucks ***** for you because thats one of the crappiest things to have to fix.

+1 on the cowls leaking.That is the number one reason for wet floors.If indeed it leaks when you pour water into the cowl then there are two ways to fix it.the hard way and the easy way.The hard way is the best route,which entails taking your car most of the way apart so you can cut the spotwelds holding the upper and lower cowl pans to get the pans out.
That being the best way to fix it,there is an easy way. It wont "fix" the holes in the cowl but you can get a cowl cover to keep any water from getting in the cowl in the first place.
There are several posts on here about cowl covers just use the search feature to find them if you decide to go that way
hope this helps

That or the heater box is shot... Just hope its the heater.. Though its a pain, it would be a lot easier than the cowl...
