Default timing belt

I'm doing my timing on my 98 RS and I have everything lined up, as far as I can tell correctly. The only thing is when I put the final idler pully on it pulls the drivers side double hashes (to align the intake and exhaust cams) out of alignment. They look like they're 1/2 a tooth off or so. The marks all line up on the belt and the teeth count seems correct.

Is this normal? And does the tensioner realign everthing?

Thanks,
Brian

Everyone should be given this site when they register, www.endwrench.com. Since you have the '98 RS I'm pretty sure you have the twin cam engine, if that matters in the case of a timing belt.
I guess my question to everyone that reads this post is, does it matter which 2.5L you have (twin or single cam)? I think they switched to single cam in '99, but I have the lil 2.2 anyway.

Anyway, try this site out, http://www.endwrench.com/pdf/engine/...ReplaceF00.pdf Hopefully this will answer all your questions.

Thanks, I found that article on my computer. I had downloaded it awhile ago and saw the stuff in the end about the left side not lining up correctly is fine as long as the tooth count is correct. So I'll just have to fire her up and see if she works. Hopefully I torqued the heads down correctly...

Yes, the 2.5 went from dohc to sohc in 99. This post is basically referring to the 98 and older ej25. SOHC won't have to worry about aligning the cam gears (intake/exhaust) in relation to each other cause there is only one cam gear for each head. If you have a 98 2.2 then it should be a SOHC. You can tell if it's a SOHC or DOHC by looking at the timing belt cover. If it has 2 gears on each side of the engine then it's DOHC or 1 on each then its SOHC.

Thanks for the info.
