The bird in my profile has been setting for several years. Finally get back to it and got her running but aside frommaome fuel leaks it's developed a lifter noise (louder then normal) on the driver side. I assumed it was bleed down from the amount of time it's been setting, but this evening I started and let it run till tstat opened up and it never went away.

Oil pressure is good 40psi @ idle, and revving didn't seem to build up pressure for the lifter.

​​​​do i need to let it run longer?

 

Lifter is stuck. BTW this should be in Gen III Internal....

 

You are correct got in a hurry
@TheBlurLS1 could you move this to the correct section?

Block is iron 6.0 but valvtrain is l92 heads for what it's worth

 

1/2 and 1/2.... but should still be Internal....

 

Marvels Mystery oil to the rescue! Wouldn't hurt to pull the valve cover and check the rocker arm bolts to make sure they are torqued to at least 22 ft lbs.

 

I was either thinking marvel or lucas treatment. But gonna pull the valve cover first. Cause it's loud almost like it's smacking the vale covers....

 

You can easily run an LS motor with no valve covers. Just remove them, plug in coils again and let hang down. we do it all the time when these POS trucks AFM lifters collapse, break springs, bend pushrods, etc etc.

 

Clearer head and less caffiene........ I pulled the VC this morning everything was actually good torque was right

I have 3"tall valve covers and I flipped them and saw where the rocker arms were slapping the edges where it wasn't quite lined up right
