Thread: Trouble setting timing.

i got tension on the chain, its super snug now definitely made a big difference replacing tensioner.

now i am on the issue that i am getting from under the valve cover, doesn't sound like the timing chain, but more like a rocker? not to sure, posted up a video

I left 20 rollers between the can gear timing marks which is What the fsm specified for,but I keep reading 21 is the right number. Any one care to verify?

Definitely, 20.

Intake keyway @ 10 o'clock, exhaust keyway @ 12 o'clock
#1 cylinder @ TDC and you should be timed correctly.

Also make sure there is no slack between the exhaust gear and the crank gear. That could screw things up.

Kyle's writeup from our "how to" section: http://www.sr20-forum.com/naturally-aspirated-all-motor/43837-how-check-camshaft-timing.html

Check that all of the guides and shims are there and the rockers are seated correctly.

thanks guys il definitely check the timing again, its making this horrible knocking sound and i keep getting a kocking code pending immediately after clearing it.

i havent read anything about the rockers being seated so i will look into that.

BTW this forum is awesome, i get much more motor help on here than on the G20 site. ha

i had a chance to take off the valve cover earlier, the shims and guides were all there and i didnt see any of them with damage, but there are still a few of the rockers that allow side to side movment. intake side on cylinder # 1,2,3 and exhaust side on cylinder #2,3 could it be that it was having this issue before, but now that i have a new tensioner and the chain is fully tensioner i am getting much more noise?

If the noise is consistent regardless of the RPM, you can usually draw the noise back to something in the valvetrain. If the noise is intermittent and only comes up during certain RPM ranges, you could still have cracked guides, and a chain that is slapping around with variances in the tension.

it stays pretty quiet at idle but around 2k rps to 4k its the loudest..also its loudest on the lower gears and when im giving it throttle.

its weird though because i wasnt having this issue before i put in the new tensioner..but i also did reset the timing chain because it got knocked off a tooth by accident when i had the VC off

Watched the video. That is a strange sound, reminds me almost of a transmission whine.. Of course that's not it, but its def not normal. At first it just sounds like a noisy valve train

right...i find it off..il take another video today on my way to school
