Here's how the engine lubrication system works in your car, and why oil is so important!

It all starts down in the oil pan:


Oil gets sucked up through the pickup tube and into the oil pump:


The oil pump is a gerotor type:


Then oil flows through the upper oil pan to get filtered:


This is what the inside of a neglected filter looks like:


It's then fed through the timing cover before going back to the engine block's central gallery to feed the main bearings.


The timing cover carries the oil to the main block gallery and splits it off to the VVT gears and timing tensioner:


The main bearings lubricate the connecting rod bearings on the crankshaft through internally drilled holes in the crankshaft:


At the engine head, the camshaft bearing cap has tracks for lubricating the camshaft and feeding the VVT gear:


This is the solenoid that controls it all:

Going to come back and look at this in detail. Thanks.
