Oil Priming a GM Truck Vortec LS Engine – Rebuild Video 4

The Vortec (LS) engine does not have a distributor for spark. It has a coil for each cylinder. This means we can’t use the old trick of using a drill in the distributor to build up oil pressure. Luckily, with some ingenuity and a little patience, these engines can still be pre-lubed.

Using an old oil pressure gauge and a drill powered motor to build up oil pressure, I was able to get oil through all the passages and oil up all 16 push rods to the rocker arms. I watched a bunch of videos on YouTube and created a hybrid solution from my favorite vids.
So, check out the video, and be sure to check out my other videos, subscribe to my YouTube channel, and like and comment.   Thanks!
