All you have to do is use a light and a magnifying glass and look at the machine grooves on the parts. Cracking the cap leaves a slightly irregular mating surface between the rod cap and rod. It would be quicker (and pretty close in cost) to just buy a rebuilt crank and new rods. Also the large chamfer and small chamfer should always be on the same side as each other on that rod. How do you get 2 feet of snow out of a convertible if you accidentally left the roof down? In modern automotive internal combustion engines, the connecting rods are most usually made of steel for production engines, but can be made of aluminium (for lightness and the ability to absorb high impact at the expense of durability) or titanium (for a combination of strength and lightness at the expense of affordability) for high performance engines, or of cast iron for applications such as motor scooters.

Micromatic automation technology includes the handling of connecting rods, caps, and bearing shell during the assembly process. lots of patience start by looking at the rods big end,you will see where one side is slightly tapered that will sit up next to crank shaft radius,the square ends will be side by side.The bearing locating notches which the bearing tabs sit in will go on top of each other.Now if your pistons are on the rods you will notice a dot or other mark at one end,along the same line as the piston pin.This mark is to be toward the front of the engine.By lining up the pistons and the way the rod caps are on you will be able to find which is left and which is right side parts.Now use plastigauge to check the rod clearances,you may have to move these around until all clearances are with in specs.Good luck and just take your time,you will get this done. i think i may have mixed mine up :/ If the connecting-rod caps are mixed up, the crankshaft willnot rotate when you assemble the engine.

According to Modular engine expert Sean Hyland, all Modular engines have cracked powdered-metal connecting rods except the 2000 Cobra R (fitted with forged Carillo rods), the supercharged 2003 Mustang Cobra (fitted with Manley forged-steel rods), and the supercharged 2007–up Shelby GT 500.
