Did valvesprings and studs today have question

I did my valvesprings and studs today but when i set the engine to TDC and removed the cams I did the ziptie trick around the cam gears. I use air pressure the keep the valves in and did cylinders 2 and 3 first because they were down. I left the car in gear with the parking brake on and put a little bit of pressure into cylinder 4 and it moved a bit and pulled the cam gears together. the timing belt may have slipped a tooth on the crank a little bit, so I was going to take the RF wheel off and check the timing against the mark tomorrow.

Does anyone have any advice? I got all 16 valvesprings done (what a pain) but now I know the timing is off. I found the marks for the timing on the cam gears (this was easy) but I don't know about the crank timing mark.

Please respond. I want to do this tomorrow and I don't have any special tools nor do I know if I need any. The timing belt is still on there its just my cam gears have been removed so I will have to squeeze it all back together and set the timing. I was assuming this wouldn't be so bad.

Oh, the work being done was headstuds, cams and valvesprings (without removing the head)

So just continue as you would a timing belt job. If you didn't put everything back together yet, and just slipped a tooth, take some tension off the belt and slip it off the cam gears. Line them back up to TDC with the marks on the valve cover (might need 2 wrenches and extra set of hands to hold them in place while you or someone slips the belt on). Tension it back up and check your marks again, it pulls on the gears when it tensions. Might have to do it 2 or 3 times to get it lined up just right after it tensions.

The thing I'm worried about is the balance shaft thats on its own timing belt. This wont be affected right because its on a completely different belt right? I mean there is no way it can be out of time with the rest of the engine because the only thing that slipped is the cam/crank timing?

I was hoping I wouldnt have to do the majority of the steps in the timing belt "how too" because i'm using the same belt that is already on there, it just is off position.

I was going to check all three marks (intake cam, exhaust cam, crank) and make sure everything is lined up good.

I'm worried about balance shaft issues because I saw that a bunch of times in all of the timing belt threads.

thanks for your answer!

You have to check the oil pump sprocket too, because that is where the second balance shaft is. To do this you will have ot remove the lower timing cover. You don't have to worry about the other balance shaft though because that on is on its own belt off of the crank. In other words there are 4 marks to line up (both cams, crank, oil pump).

yes I just realized that (I'm piston dumb, - used to working on rotaries)

Thanks SO much for your help.

But wait... so the timing mark on the oil pump lines up just like the crank/cams? As long as the marks are together I am cool, or it can still be "out of phase"... I was reading so much it sometimes get confusing.

You're going to have to remove the accessory belt and timing covers to check and make sure all the timing marks are still on. EvoMoto has a timing belt how-to write up that should help you and answer most your questions. Its not too bad of a job, just take your time and be careful.

I think I've gotten everything timed correctly now. The marks lined up pretty much perfect. The front oil driven sprocket gear is tricky. I tried setting the mark at 12 o clock and letting it fall but it really didn't want to fall. I did this one by rotating it one way from 12 o clock and then the other and seeing which way it wanted to go easier. I set the timing with the sprocket where it was easier to turn counterclockwise back towards the little timing mark. Is this right? I don't want it to be 180 degrees out of phase.

bump for feedback on oil sprocket
