could desire to or no longer it extremely is your cooling fan? Get out and dad the hood next time to get a greater powerful look and pay attention. On those warm summer season days that fan has to artwork somewhat greater effective to maintain th engine cool.

Cooling down of the cat. converter. The dripping sound comes from oil dripping back down from the top parts of the engine to to pan................

It is called either bad timing or back up in the exhaust. Most likely though it is caused by a bad timing in the engine. Usually though, it only lasts about 10-15 seconds.

most of what you are hearing is due to the catalytic converter cooling down after operation,often engines will pop & creak while cooling down...........dont be concerned........theyre not gremlins.
