Blueprint 103 - Connecting Rods
Connecting rods are the crux of the engine. They're responsible for carrying the force of the explosions that occur in the combustion chamber and using it to turn the crankshaft. Oil clearance specifications of the "big end" and "small end" are crucial to maintaining consistent oil pressure. In this video we take 3 measurements: Rod Gap Rod Journal (also called Crank Pin) Diameters "Big End" Bore diameter Using the Journal diameters and the "Big End" Bores, you can calculate your oil clearances of each bearing. The process is illustrated here. Anyone rebuilding an engine who doesn't know its history should check all of these clearances whether or not they're re-using the rods. If the crank, bearings or connecting rods are going to be replaced, it's imperative that you measure the new parts as well to ensure they're in spec.

LSx Replace Pistons on Connecting Rod at Home DIY - 4.8 Flat Tops in a 5.3 - LS1
In this video I am pulling one piston out at at time from a 160k mile 5.3. This 5.3 will be going into my 1987 C10. I then show the removal of the dished 5.3 piston from the connecting rod and then the mount of used 4.8 flat top pistons back onto the connecting rod. Then the 4.8 piston and rod are inserted back into the block. This is all happening at home in my garage with basic tools. I do use a press to remove the 5.3 piston but you could easily use the propane torch for the removal by reversing the mounting procedure that I show with the torch. With this video, I am not suggesting that everyone reuse their old piston rings. I am only doing an experiment to see how they hold up. That way others can judge on their own if they need to replace their rings while working on what ever project they may have. I do suggest cleaning the rings better then I did in this video. I do suggest that you replace the rings if you're inside a motor with 160k miles on it. By installing flat top 4.8 pistons into a 5.3 the compression will change from 9.5:1 to 10.6:1. Edited 4-30-14: I just started this engine up last week. I did a compression test, it came back good. I've got a video of it running on the stand here: http://youtu.be/VogkaVNGkCU UPDATE 8-16-14: This motor is running strong. Here's a video of me abusing it: http://youtu.be/AwovZwPUOHY ========================================= Follow me on Facebook here: https://www.facebook.com/AGearHead4Life?ref=br_tf ========================================= Check out my other videos like this on the link below: http://www.youtube.com/user/AGearHead4Life
