Good evening Ford Crew.
1997 Ford Explorer, SOHC 4.0. I have driven this truck since it was brand new, and am very familiar with multiple timing chain issues, and how the death rattle sounds: usually starting mostly with rattle on cold starts, aggraveted by colder weather. usually not present after motor warms up.
This noise is different... AFTER having a rebuilt engine installed 30,000 miles ago, I noticed that as the engine warmed up, a clatter from the center/top area of engine developes. This never happens when engine is cold, and consistently develops after the engine is fully warmed up. The noise sounds like a few marbles inside the top of the engine. After the engine is warm, the clattering noise is constant, and does not change or go away. It increases in speed and frequency until it can not be heard at higher RPM.
The rebuild mechanic says no problem (of course), and I vague recall that my new engine twenty years ago made a similar disconcerting noise.
Any ideas? Anyone else have this?
Thanks in advance.
