Where does the oil go in an overhead cam engine?
Engines with an overhead cam design have pressurized oil ports in the engine block that supply oil to the camshaft and lifters. The head gasket is responsible for sealing oil pressure between the engine block and the cylinder head.
What happens when a camshaft seal fails on a car?
Over time, seals harden and begin to leak. Seals can also fail from excess crankcase pressure, but that happens much less frequently. A failed camshaft seal can result in oil loss and potential timing belt contamination. On most vehicles, a timing belt replacement is a big job that requires the removal of the timing belt and camshaft sprocket (s).
When does the camshaft position sensor stop working?
Note: If you are new to all this, you should know that the camshaft position sensor is a different part from the crankshaft position sensor. Just like every part or component in your car, the CMP sensor will eventually stop working when it’s reached the end of its service life, because an internal part, wire, or related component has failed.
What causes a camshaft to run out of travel?
As you increase valve lift, the rocker arm swings farther on its axis. Therefore, the slot in the bottom of the rocker arm may run out of travel and the end of the slot will contact the stud and stop movement. The slot in the rocker arm must be able to travel at least .060-inch more than the full lift of the valve.
What causes the camshaft to be over advanced?
The over advanced position can be during the retarding or advancement phase of the camshaft timing. What causes the P0024 code? By using the camshaft and crankshaft sensors, the ECM detects the camshaft timing to be over advanced. The Oil Control Valve (OCV) to the bank 2 camshaft is stuck closed or has clogged passages.
What is the diagnostic code for camshaft position B?
Cost of diagnosing the P0024 code. P0024 is a diagnostic trouble code (DTC) for “Camshaft Position B – Timing Over-Advanced or System Performance (Bank 2)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What causes bank 2 camshaft to be stuck?
The Oil Control Valve (OCV) to the bank 2 camshaft is stuck closed or has clogged passages. The oil is too thick, causing the passages to become clogged due to lack of oil flow to or from the camshaft phasers that control the timing. The camshaft phaser is stuck in the advanced position due to damage or defects.
