Noticed something strange this morning, and wondered if anyone here has any thoughts.
Truck starts OK. I walk to the front of the Explorer, and I hear some popping near the front of the engine block. Popping is inconsistant. Kind of sounds like carb blow-back. Another analogy would be that it sounds like ice cracking.
Will see if I can isolate the problem tomorrow morning, but thought I'd ask the question to see if anyone else has gone through this.
If you live in a cold area at this time when you turn the engine off its normal for the strange sounds from the exhaust cooling down sounding like that. I get that all the time. Hope this helps
