I'm about to start building a 5.3L LMG engine from the bottom up. I plan to install all new bearings, seals, and which ever bolts have to be replaced. I know some bolts can be re-used, while others are meant to be replaced. This will be my first complete re-build, so I need a little guidance.
Where can I find all the torque specs for a Gen-4 engine? Is there a book or service manual that has all the torque specs? Also, I will need all the tolerances for all the bearings. Where can I find those? I know there are countless videos on Youtube, but I'd prefer to have everything in one place. What's the best advise for someone doing a complete rebuild for the first time?
