Got the new oil pump on and primed on my 4.0. Have slightly more pressure than before. Yay!

New noise I'm getting now:


I did it from the interior because the garage echo is horrible. I get the noise from startup. The noise didn't seem to get louder when I revved it, so I'm not sure. I do remember one of the rods had a VERY SLIGHT wiggle when I was under there replacing the pump. Any suggestions?

 

Just recorded second clip out of the garage:

 

thats really hard to hear but is that a lifter ?? what oil did you change in to the motor??

 

Put in 10w30. Was running 5W30 but with 140K, was recommended to run heavier stuff.

 

rod knock will get alot lounder when rpms go up........check the common things...TC bolts,balancer.

 

not meaning to hijack here, my 99 was making the same noise then died noise got quieter when rpm's went up. then it just died while idiling wouls a cracked flexplate cause that to happen?

 

maybe.....get under there with a flashlight and check....

 

i hope mine will be that simple...we'll see.
