I did a quick search for school shootings during the Trump Administration... and Google didn't show any results.
However... Google did show results for the most amount of "mass shootings" during the Trump administration.
Problem with that is... the FBI considers more than 4 or more people...
Magnaflux won't work on aluminum heads. That's why I suggested dye penetration.
He replaced both bent exhaust valves... and got compression up to spec. However... the guides may still be an issue.
The LS 3.9 mV8 has no rocker arms. Wrong engine.
Usually you set up a dial indicator on a base... and check for lateral movement of the stem in the guide.
Depending on the manufacturer... usually determines the specs... which are found in the book for whatever specific engine.
Only way to really find out is to install the center section and check backlash. Also test the wear pattern after install.
That's done by "painting" some of the teeth on the ring gear... and turning the assembly to see how deep or shallow the gears are meshing. Contact on the center of the...
There were a few good posts and "write ups" from about a decade ago regarding the front sway bar swap.
I tried digging around the site some... but haven't found them yet.
Are you sure about that? Did you confirm that it was in stock? FPG and Tasca have been a bit suspect lately with "in stock" parts... only to find out the part is back ordered.
Just a thought... but maybe the bent valves damaged the valve guides on #7 just enough to cause extra oil consumption.
Take the suspect head to a machine shop and have them pull a vacuum on the intake and exhaust ports of #7.
Maybe have them dye-pen the head too to check for cracks.
There are ways too eek more power out of the 3.9... but it's expensive and takes time, parts, and labor. (and tuning) It would be easier and cheaper to make the LS handle better... than going fast in a straight line. I'd like to see that Buick take some of the curves I have taken.
Enjoy the LS...
Better yet... put him on here to share his knowledge. He'll leave with his tail between his legs.
We can start with suggesting the wrong fluid. (rolleyes)
Sounds like all he is... is a fluid jockey.
