What do you have to make sure to line up perfectly on the camshaft and crankshaft?
In order for the intake and exhaust valves to line up precisely with the up and down cycles of the piston, the camshaft and crankshaft must work together with precise timing. In order to do that, a timing belt, timing chain, or other synchronizing device connects the two shafts.
What is the difference between the camshaft and crankshaft?
A camshaft uses egg-shaped “cams” to open and close engine valves (one cam per valve), while a crankshaft converts “cranks” (the up/down motion of the pistons) to rotational motion.
When does the ring Gab break on a Subaru?
This is when the spaces in between the ring gab break. This is mostly false. This myth is used to sell aftermarket internals and aftermarket tunes that boast the claim of reducing your chances of this happening. In a way, the myth is true, but not for the simple reason of the structural design or factory tune.
Where are the piston rings located on a Subaru?
The piston rings are placed into grooves on the top edge of the pistons, and they close the small gap between the piston and the cylinder wall in order to hold back exhaust from entering your crankcase. Some still slips by through the ring gap, and this is know as blow-by.
What do you need to know about a Subaru long block?
It is everything, minus the intercooler, piping, hoses, and fluid reservoirs. Also known as Turn-Key. A complete long block strips away bolt-on components such as your turbo, manifold, and headers. A bare long block is the same thing, minus the valve covers, timing components, cams, and pulleys.
What makes the wheels turn on a Subaru short block?
At the very heart of the short block is your crankshaft (crank), which turns the crank pulley on the back of your engine. This rotating motion is translated to your drivetrain which turns your wheels.
