well i know my c5 motor alway had that type writer tappin type of sound, (if any of you know what im talking about) but recently i put my exahiust and header on and for some reason a valve tap seemed to be present, though it was an exhaust leak but i dont think so, so i had the valves adjusted still there, i hope this isnt jsut in my head. if it is a valve tap how can i got about correcting it.

 

its it a ticking or a tapping? lol

 

removal of the cast iron OE header will result in louder valve noise.

the injectors also make some noise.

does the ticking increase as you increase in RPMs??

 

yeah my stock injectors tick a and its a pretty nice noise maybe that could be your problemo

 

I have noticed a little ticking from mine also. I thought it might be the valves but they were adjusted about 7,000 miles ago after I broke in my new engine. You dont think it would be an electrical problem do you? I got a new longblong under warrenty but I dont think they changed out the distributer and I know they didnt change out the wires. Keep in mind the car has about 89,000 miles so I fiqured a good tune up is almost due anyway.

 

yeh i def noticed it more when i put the dc header on, so that may be it. and the noise to does speed up as i increase rpms.

and i know the injector ticking noise, its not that

 

ttt

 

bump

 

the noise is there all the while... when you remove the stock header you can hear the noise it better.

-adjust valves
-live with it

 

fuel injectors also have a ticking sound. but if you have had them adjusted then your fine...unless the person that adjusted them did not do them right.

 

well...

 

I do all of my engine work including adjusting the valves every 1500 miles and after every 5 races. I found that due to the high rpms and heat your rollers collect a considerable amount of resedue which causes you valves to open a little more and not close completly. after cleaning them the tick (not a full tap) goes away until a few hard miles. I installed a set of skunk 2 cams on my boys car and his ticking is practicly non existant. so dont sweat it. only worry if they are rattling of tapping inconsistantly.

 

It's only in your head, don't worry about it. (engines do make noises by the way )
