Do ticking valves hurt anything?

Hi I just wondered if ticking valves hurt anything? I have at least one making some noise and it might be a while before I can lash them, and I just want to know if it's alright to keep driving with this problem without hurting anything? Thanks

Re: Do ticking valves hurt anything?

specifically on Zuks,"i dunno", but it could be ticking because of cam/lifter problems...plus the head is aluminum, so it may do some damage to the valve seat area...just my damn two cents anyhow...maybe not much help...but i'd find out why it's ticking soon...

Re: Do ticking valves hurt anything?

Ryan,
I am not sure, mine have ticked for over a year and I finally opened up the valve cover and found that I had
somehow blown 2 of the intake valve guides completly out and they were "ticking" up and down on the valve
stims.
and yes it did cause problems, Looks like I may be replacing the head....????

It wouldn't hurt to just have them adjusted and inspect them.....

Re: Do ticking valves hurt anything?

Seriously, The tapping can be the valve seats coming loose or the misadjusted rockers tapping on the top of the valve stems. Neither are particularly good things.

I'm not ure how helpful the Haynes manual is on adjusting valve lash, but the '88 shop manual has detailed info on setting valve lash on an 8-valve G13a. Send me personal mail if you would like the details on it.

Re: Do ticking valves hurt anything?

Well the tapping in my old engine was the valve guides flipping up and down from the head to the top of the
valve stem... also, you get quite the oil injection into the cylinder....

Are you burning any oil, or large quantities of oil?

It is not hard to just pop off the valve cover, just make sure you are carefull not to damage the gasket.
and when you put the bolts back in , they don't need to be torqued or you will bend in the cover.....

then take a very little flash light and start looking inbetween the springs and look at the rockers and such.

good luck,,,,

Re: Do ticking valves hurt anything?

Thanks for all the quick info. I Actually got a chance to tear into it tonight. A friend of mine whoose a mechanic and I lashed all the valves according to the Haynes manual, and when that didn't work we tried a few other ways and I still have a ticking sound. Accoding to him if we tighten the valves anymore i will lose engine performance. He says there is nothing to worry about and that i can keep driving it. It still really sounds like a loose valve. Is there any kind of oil additive that might quiet it down? Thanks again

Check the fuel pump with a long screwdriver toughing the fuel pump and listen to the handle
of the screwdriver. It may be the fuel pump lever bouncing on the cam eccentric.
