My oem was green as well as for this oil pressure issue and using the black o ring I take it this could be mu issue?

 

sounds like a cam bearing issue .

 

I'm hoping not but I wouldn't be suprised. Cam bearings can knock only when hot? I talked with my coworker and he thinks it's no lower end since it only do it hot. Said mains will knock hot or cold as well as rods. I can't even think clearly ny brains tired of guessing. I'd hate to pull it out and find out I overlooked something as small as an o ring. Also I did find out that I got the wrong specs for the retainer plate...saw in a thread anything over 12ft lbs cracks the plate mines at 18...

 

do not use anything other than the green O ring for truck pickup tubes, yes that o ring could cause low oil pressure, in fact, no o ring causes 0 oil pressure, if there is not an adequate seal, oil pressure will be "lost" through there

 

Isn't the motor already damaged regardless of the cause?

 

Subeone thank you sir. Andgmc that's what I was thinking after spending what I did in just pulling it and sending it back. It started knocking again yesterday

 

Well the builder is taking it back. Here's the video lol

 

Why is your harmonic balancer pulley so out of whack? Does not sound good.

 

That puppy is toast...I'm not sure I'd go back to the same shop that jacked up the build the first time but hey...who knows. Good luck - post a new vid when you get the block back.

 

thrust bearing took a **** ?
