when i bought my 65 a few months back it had some aftermarket chrome valve covers on it with breather caps. but i noticed when the car is running i see smoke coming from the filler hole.and when driving u can smell the smoke(oil burning smell). i was told that there was supposed 2 be a pvc valve from the valve cover to the carburetor spacer. is this true?where is this smoke coming from and where should it go?i noticed mustangsplus has breather caps with slanted tubes coming off them so i was thinking to buy 1,and a pcv valve and a piece of hose and running it to the spacer to suck the smoke out but will this suck the oil out to?any help would be great.i really want 2 know how 2 fix this smoke problem.

thanks.

Your engine crankcase needs to be ventilated. This is normally done via a PCV valve. Best bet is to get the appropriate grommet for the valve cover and PCV valve, then run a hose from the valve to a vaccum source like the carb base.

65mustang:
Your 289 engine is supposed to have a rubber grommet on the passenger side valve cover. The PCV (Positive Crankcase Ventilation) valve sits down in this grommet. Then there is an L-shaped hose that runs from the top of the PCV valve to a fitting that is on the back of your carb spacer. The hose is held in place on both ends with some strong clips made of thick wire...you could use two small size "radiator" style clamps, but these
are not "correct" for your car. (I don't know how accurate you want to be.) The PCV valve is available at any decent auto parts store. The hose (an original Ford part that was still available last time I checked) and the correct style wire hose clips are available from any good Mustang supplier.

Make sure those "chrome" valve covers have a baffle under the pcv hole or it WILL suck engine oil. Some of the cheap covers do not have baffles. You also might have to adjust the idle and or mixture screws a little, since the pcv valve does introduce a small amount of air in the intake, and it might throw the carb adjustment out a little.

thanks for the help. i bought the grommet and pcv valve and hose and hooked it all up and now i dont see anymore smoke. i bought a breather cap with a stem for the driver side valve cover and have to go buy the fitting for the air cleaner so i can hook up the hose from the cap to air cleaner. thanks again for the help.
