Honda D16 Connecting Rod Lightening
Watch as John Edwards @ Costa Mesa R&D Automotive Machine Shop takes a set
of D16 Honda rods and lightens them on the engine lathe. He removed over 40
grams of material! (949) 631-6376 Don't forget o 'Click' and SUBSCRIBE!
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.
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:
This motor is running strong. Here's a video of me abusing it:

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
In this video we take 3 measurements:
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.
