145,000 k recently changed oil and did not use mototorcraft filter. used fram last time with no
problem.

Have you had it since new? Sorry, I should have asked that with my other question.

 

And using the correct weight oil? These engines typically are trouble free. Guessing, it sounds like it could be main bearing(s).

 

If you did an oil change then it is because the timing chain tensioner was not upto pressure. If the noise went away, don't worry. If the noise persists I would get it checked out.

I always have filled up my oil filters to reduce dry start problems. 225k and no chain noises ever.

 

FYI : Fram filters are junk

 

Have not had since 120,000 k. Will try new oil and filter reccomended by OEM, Start with the simple stuff.
Thamks to all!!

 

I'll 2nd and even 3rd that
