CP-Carrillo - an inside look
CP-Carrillo: an inside look into the making of pistons and connecting rods
for the high performance racing industry.
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.
Land Rover engine rebuild stuff you must know - CON ROD
There are more things to check with a feeler gauge than just valve
clearances on you Land Rover four cylinder engine. In this video we share
with you how to measure of couple of things on the 300tdi Land Rover engine
when undertaking repairs or overhauling an engine. Checks you should carry
out when removing the con rod from the crank.
We look at crankshaft end float and the need to check for distortion in
the con rod big end.
A Better Way to Install Rods on Pistons
Installing spiral locks into a performance piston is a pain. I've found a
tool that can make your life a lot easier when it comes to building

Blueprint 105 - Main Bearing Oil Clearances
In this episode we measure the bores for the crankshaft and calculate the
oil clearances based off of information gathered in the previous video. If
you subtract the diameter of the crankshaft from the bore diameter, you end
up with your oil clearances.
If this were an assembly with new parts, I would have also paid close
attention to bearing measurements 45° off-centerline just to make sure the
bearings aren't pinched. I would also have double-checked the clearances
using Plastigage. But what I'm doing here is just getting baselines prior
If you're doing a dry assembly like this, DO NOT ROTATE THE CRANKSHAFT.
Without oil, there is nothing preventing it from being damaged.
COME Racing block clearancing & component balancing.
You need to make sure components fit the cylinder block correctly and that
rotating and reciprocating parts are correctly balanced. This in another of
our short block V8 building videos goes through these functions.

How To Swap Pistons on Connecting Rod at Home - 4.8 Flat Tops into 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:
