Without a better pic, there is no way to tell for sure. I am not going to tell someone it looks ok, if I can't tell it really is.

Thats true, but i'm sure not gonna tell him its off one tooth either as it isn't that obvious. I'd hate to tear into my motor if its not off one tooth, although the front cover isn't that hard to do. I guess thats probably a sign i've had my car apart to many times.

Re: Remove timing chain cover = dropping the oil pan?

I'm in college right now to be a laser tecnician, and my first year was all electricity. Electricity does some weird things when not grounded properly. It can and will change voltage quite a bit. If you are driving and the ground isn't making a clean connection, it can cause the electronics and sensor to act differently and the compuer would probably try to act accordingly. I'm not saying it is your problem, but it doesn't hurt to go back and re check grounds especially after a rebuild.

Re: Remove timing chain cover = dropping the oil pan?

Also another thing to check is your plugs again. Even though you put in fresh plugs, maybee one cracked the porcelin. You might want to look under the hood in darkness to see if there is any arcing. You can also take a spray bottle with water and spray it on each header to see if you have any cold cylinders. Those are a couple of ways to see if all of your cylinders are firing correctly. They aren't 100% for sure, but its the easy stuff to rule out first. It's too close to tell in your picture about the sprocket alignments.

you had an extra "/" at the end of the link

yours looks fine with the dowel at 3, the cam at 6 and crank at 12

look at post #26, no need too e-mail it, it works

on topic, i didnt drop the pan at all too remove or install the timing cover
on the inside of the timing cover is a lip that the front gasket seats into. when you pull the timing cover off. you will see that the lip has pointed edges on each side...you can cut/grind those "ears" off the timing cover for an easier install without dropping the pan

dont take too much away tho as you can go too far and cause an oil leak. only about a 1/4" needs taken off each side
