Need to Know what SIZE Engine to give this Internal Technical Info to you. Externaly The Crank Sensor picks it up from Harmonic Ballancer and so there are NO EXTERNAL Marks Nor Does the Manufacturer Provide this Info
There is a 2.4L DOHC Engine and there is a PROCEDURE Rather than MARKS on the 2.4L and Requires you to Fallow EACH STEP EXACTLY and in a Very Long Texting . But On the> 3.4L Engine and INTERNALY on the 3.4L the Marks Alighn With #1 @ TDC CAM Mark is STRAIGHT DOWN and the CRANK MARK is SRTAIGHT UP < This is Internal marks on the 3.4L Engine
GM does not provide timing chain timing marks, or information to perform timing chain service without the special tools shown in the timing chain service procedure

If the "check engine" or "service engine soon" light is flashing, it could be the engine is miss firing. This could be caused by a bad spark plug wire or spark plug. How old are they? After changing the plugs on my 2001 Olds Alero (at 125k miles) I noticed the engine occasionally miss fired and the "service engine soon" light started blinking. I used a timing light to determine which cylinder was miss firing and changed that spark plug wire. Advise would be to change the whole ignition wire set, but I was cheap and just changed the one wire, which cost $23 from a GM dealer. That was 14 months ago and the car runs great.

SOURCE: Where is the radiator drain plug for a oldsmobile
The radiator drain plug is on the lower left front (drivers side) of the radiator. To access it you may have to remove the front air dam. It is a white plastic plug and requires a Torx socket to loosen (sorry but not sure of the exact size of the Torx socket). Insert Torx and turn counter clockwise a half turn. Pull the plug out using a pliers until fluid begins to drain. Be careful because this is a plastic plug and may break easily. When fluid is finished draining simply push the plug in and turn clockwise half a turn with the Torx socket to secure.
SOURCE: my 2001 oldsmobile alero has a cylinder #4 misfire
The misfire can be caused by an open injector , injector pulg or circuit, bad spark plug ro wire lost compression as a burnt valve blown gasket ( antifrezze foulingthe sparplugs ) Low compression from overheating over mileage or flooding from injector leaking. Take out the number 4 plug and any other and compare what they look like if they don't look the same swich them and see if the miss moves to the cyclinder that the #4 plug moved to. If it does run good or misses on the new cyclinder change the spart plug with new and then look for loss of coolant or oil on plug wire carrect leak and try again
