This is coming from a supposedly new Ford SC engine, with only 8,000 miles on it, and the noise started when i switched to 15w50 mobil 1 synthetic.
Sounds like a bunch of pool table balls clacking together continuously, or kinda like a big diesel engine at idle.
It only happens at idle, and only after the engine has warmed up. It also is running rough with a bad misfire that rarely goes away.
Am I in trouble? Is this motor about to crap?
I notice sometimes it's louder, and sometimes it's soft, barely noticeable. I do hear a couple of lifters tapping along with it all the time.
What do you think is going on? Do i need to replace the lifters?
thanks-
