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.
22RE Toyota Pickup/4Runner Valve Adjustment
A recent major oil leak from my valve cover gasket leak meant I had to
remove the valve cover and reseal it. This was the perfect time to film how
to adjust 22RE valve clearances. Grab a snack and a frosty beverage and see
how it's done.

22RE Engine Rebuild: Part 1
This is part 1 of the 22RE engine rebuild. At this point, most everything
has been removed that is going to be replaced; what's going on is a race
ported and polished head w/ 280/440 cam, 70lb valvesprings, titanium
valvespring retainers, 1mm OS Ferrea valves, matched and flowed injectors,
and new rocker assemblies, HD timing chain kit and a whole bunch of red and
silver powdercoated top-end goodies. Props to 22reperformance.com for
providing top-notch products and customer service.
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.
