2.8 Ignition Timing Marker

[dguy]

Does anyone have a photograph of the ignition timing marker on a 2.8, where the numbers are reasonably visible?

Mine...  aren't.  Even after a bombardment by various cleaners, I can't make out the engravings.  

There is however a suspicious white paint mark about two points in from the left-hand edge of the tag.  I'm guessing that either the factory or a wrench placed it there.

Why?

When I checked the timing this afternoon, it was retarded about 4 degrees past the white mark.  After advancing it to the white mark, she runs one heck of a lot more smoothly.  

Like I said, if anyone has a photo of the timing marker (on- or off-engine), please post it.  I'll be making an appointment for her first and only e-test soon, and this is the last item on my list.

Here you go!  I found this on a PFF posting a while ago and saved it.  I was in the same boat as you when adjusting the timing this past spring...

Thanks Tyler!

oh thats nice! I wish my timing marks were that easy to see...mine are all INSIDE the tranni on the flywheel...I have about 2 pounds of goo on mine so I just guess at my timeing!

Knocking.....keep dicking with it...no knocking....dont touch it!

Hmmm...  for some reason I could see the engraved numbers today.  Good thing too--the left-most mark on mine is 14°, not 16° as in Tyler's photo.  Not quite sure why I didn't notice them yesterday.  

In any case, my adjustment yesterday left her at about 12° of advance.  No wonder she ate up 1/2 a tank of fuel over the 130km round trip to work and back.

si the timing mark bouncing around when under the gun or is it pretty stable?


might be time for a new chain.

It makes an occasional hop, but nothing erratic or constant.  ...and to my old eyes the timing is identical for both cylinders 1 and 4, which is another good sign.

E-test minus 48h 40m and counting.

NA NA NA my 3800SC doesn't have a distributor and it flew through emissions. Such old technology some of you slower guys are using. Must be a severe fear of speed and power.Dan
