I have a 99 civic dx with 112000 miles on it. i am currently getting my parts together for a k20a2 sawp and uhhhhhhhhhhhh there is an issue with my current engine. recently it has started ticking when i accelerate (it eventually stops at about 25 mph) even when i am parked and i give it gas it still ticks. My cat converter and exhaust manifold are old and rusted out the *** so i am hoping its that and not a valve issue or even my timing belt which probably needs changed. any thoughts would be greatly appreciated!!

You probably have a valve ticking in there. Go ahead and do a valve adjustment and that should fix it before it gets worse.

does it mean anything if it only happens every once in a while?

Does it stop when u push the clutch in?

If it was a valve ticking it would do it all the time basically.

That's what I'm thinking it is since it's sooooooo rusted I'll check tomorrow once the rain stops and let you know what I find
