You had some work done - what work, and did it involve the timing belt?

What's your mileage and when last was the timing belt changed?

How much slack do you have on the belt between the two cams?
Hi Ron,
Thanks for the feedback. As far as the work that was done--that is a long story. To boil it down, the transmission was repaired and upon getting the car back it ran like crap. Turned out to (most likely) be due to the air box left open of all things which made the car run super hot (diffusion welded upstream o2 sensor to manifold, blew radiator) and caused some permanent engine problems which the kia dealership eventually gave up on trying to resolve (specifically, a knock sensor code and some corresponding predetonation).

Recently, I brought it to another mechanic to have front wheel bearings done, and talked to him a bit about what happened previously. It seems that he tried to resolve our problem, but (interestingly) did not tell us. It was clear that he looked at things which are not the wheel bearings; for example, the clamps on the intake pieces had a couple of tightening screws that were replaced. When we got the car back this last time, the engine sounds different and has very little power. The predetonation (and code) is gone. I think the mechanic was trying to help and may have caused more problems in the process.

Car has 115k miles, I replaced the timing belt at 100k (thanks to instructions on this forum). Slack is fine.

I certainly don't expect anyone to pull off their timing cover, but I was hoping someone would have some pics from when they did theirs. I always take a picture when I start work, unfortunately I no longer have the picture I took from when I did the timing belt . If I recall correctly, the correct orientation actually has the E/I marks pointing in a little bit.

Here is a picture of each cam straight on. I put a skewer across the bolts for reference, as its hard to get a good camera angle. Thanks for looking at this, and let me know if it looks right to you. It looks to me like each mark currently points out a bit.

Tension is fine btw.

Most folks, myself included don't take photos of a job like this when its as simple as lining up the timing mark on the cam and crank pulleys with the mark on the timing belt cover backplate.

The photos you posted don't make sense - the mark on the backplate is cut off from the top of the photo - all that's needed is to position the crank pulley on its mark, then confirm that the two cams markings line up.

Quality and not quantity counts.

Oh geez, the last car I worked on didn't have marks on the steel plate so it was a matter of making everything vertical. :/
Using the marks on the steel plate, the timing is definately off by one notch.

I'll take your word on that, because I've never come across one like that.

See marked up photo - we need one like that taken direct in line showing those marks.

Maybe I just wasn't aware of the notches then, but I didn't use them.
The timing is one tooth off: it should be in tooth 18, not 19. Thanks again for the help.
