How to align distributor correctly
I have a 5.2 318 2003 and took off the distributor with out marking it. Is this the correct procedure for installing it?:
Put #1 plug on TDC compression stroke, ensure that the distributor rotor is pointing directly to #1 lug, ensure your crank shaft is at about 6 degrees BTDC.

6 degrees is not right when mechanically setting. The procedure below still needs to be done after you get it installed. Even if you get it aligned correctly and running you still need to get this procedure done. It's called "Setting Sync Signal". It is to align the cam and crank sensor signals. If you don't do this, you may run lean or rich depending on NEG or POS signal, causing pinging or burning too much fuel.
You also may need to turn the oil pump drive to mate with the distr shaft prior to putting it in.
- Connect DRB scan tool to data link connector. The data link connector is located in passenger compartment, below and to left of steering column.
- Gain access to SET SYNC screen on DRB.
- Follow directions on DRB screen and start engine. Bring to operating temperature (engine must be in “closed loop” mode).
- With engine running at idle speed, the words IN RANGE should appear on screen along with 0°. This indicates correct distributor position.
- If a plus (+) or a minus (-) is displayed next to degree number, and/or the degree displayed is not zero, loosen but do not remove distributor holddown clamp bolt. Rotate distributor until IN RANGE appears on screen. Continue to rotate distributor until achieving as close to 0° as possible. After adjustment, tighten clamp bolt to 22.5 N·m (200 in. lbs.) torque.

Thanks for the reply! I don't have access to a DRB scanner but the pictures helped. Ill set it directly on the marks for now and search for the cheapest option on getting things synced with the DRB scanner. Just out of curiosity do you know typically how many degrees the distributor needs to be rotated?

It's a Dodge Ram van conversion. Had to pull the engine to change out the oil pan gasket so I just put a full new engine seal kit (heads, plenum, rear main seal, ect...) on and forgot to mark the distributor. I'm a ways a way in NC but thanks for the offer!

Sorry to revive this thread but...
So I got quoted over a 100$ to set the timing at the dealer.... Which is enough to make me wonder if I Can use my scanner to zero out the timing. It shows how many degrees off TDC it is, can I just zero it out? Does a DRB do anything special and absolutely nessesary?
