Oldsmoble 3.4


-To start things off, in the yellow
you will see the digital EGR system.

-This is the Direct Ignition System
consisting of three coil packs that each fire two of the six spark plugs.

-This is the Crankshaft Position Sensor from the outside of the engine. It is extremely important not to damage this sensor because if there is no message from the CKP the engine will not start.


-Unlike many others this water pump is part of the timing chain cover.

-This is the Oxygen Sensor that measures exhaust gases and tells the PCM if the engine is running too rich or too lean so it can be adjusted.


-Throttle plate and body system is the intake for newer vehicles.

-The Throttle Position Sensor is there to tell the PCM how far it is open or closed so it can compensate for each change.

-This is the two stage heads that
consist of valves and spings in the bottom half of the two heads and the
hydraulic lifters and camshafts in the upper half.
