Default Cupola questions

I noticed little droplets of water working it’s way up between the threads and the nut of the head bolt adjacent to the distributor on the drivers side. Does this indicate a blown head gasket?
Also, where would I look for the cause of backfiring when the engine is turned off.

What is the cause of the gas leakage around the carb in the photo?

"...backfiring when the engine is turned off" is almost always timing when I did my first tune-up I could shut off the car and get out before it sounding like a rifle went off.


It is never good to see that on a head as it indicates a crack. If it were my car and it being driving season in most parts of the country, I would either leave it and monitor it until the winter when the head can be removed for inspection, or remove the nut and put a little permatex sealer around the bolt and tighten it again and monitor it until the winter when the head can be removed for inspection.

It looks like more than just a head nut leaking.

The gas leaking, could just be bad gasket and sloshing allowing it to leak out or float level is set too high.

Have you re-torqued the head lately? Should be done periodically.
