Chinesium in two takes

Not driving my 1965 Dart 273, but needed to move it. Would only idle cold. Once warm, needed accel pump shots and overheated. Closing the choke helped so running lean, probably a vacuum leak. Plugging the brake booster hose didn't help. Then found the PCV cap at the valve cover fell off. The rubber grommet had fallen apart. A purty after-market part. Even the rubber trim rings peeled off.

Second picture is adapter for 4 bbl air cleaner on a 2 bbl. I barely leaned on the air filter housing. The way it cracked doesn't look like a tough plastic (ABS or nylon). Another purty Chinesium product. Their new apartments with paper-mache stucco look purty too but don't last 2 years.

Yep, You'll have that now days. My carb adapter ring is from a inexpensive aftermarket air cleaner. I robbed the base reused the filter, and sold the chrome top. My PCV cap is a original HP 273 cap that fits on the stove pipe on the OEM valve cover. You must be running aftermarket covers. They don't do a very good job providing quality grommets and caps for those.
