Question What causes ticking valves?

Hey all,

A couple days ago I wrote in asking about a sound from my engion just above 2000 rpm. I figured it was ticking valves and others agreed.

Now I would like to know what causes them to tick. I have a very basic grasp of the whole valve area. Is it the springs shortening, or the holes the valves move through? Any insight would be great.

Also, what will happen if I can't take care of them for a while this summer? I'm a wildland firefigher, and pray to god I get sent to some major fires! (sorry if you live in Arizona or somewhere burning, but I'm a poor college student and 8 grand in one summer is just too good to not "fight" for )

Thanks,

Erich

a tick on a 22r serries motor. That cant be! j/k.

the tick is cause by the rocker arms being out of adjustment. very easy fix, and no, it will not cause any damage. it will be a little noisy, and a little less powerfull, but it can wait if it has too.

when it comes time to fix them, like i said, it is simple.

1. Remove rocker arm cover, AKA valve cover.

2. rotate engine to TDC on the #1 cyl., and feel the rockers that are down flush with the cam and the cam lobe is not pointing up, you will see when you get in there exactly what i mean.

3. use a feeler gauge, and make sure there is not too lage a gap.(i forget the exact gap, if you dont have one, i would not fret)

4. if they are, loosen the lock nut, and use a scredriver to adjust the rocker arms. ( with no feeler gaugem adjust until all play is removed, and back off 1/16 to 1/8 a turn.)

5. rotate engine to TDC on cyl #2, and do the same.

sorry this may sound vauge, but it has been a long, hot work week, and i am tired, and dont feel like pulling my valve cover at the moment. it really is simple, i figured it out by opening the engine and fiddling until it worked. the 22 series of engines is the simplest i have ever worked on, you should have no problem.
