Title: 305 tbi ticking sound
Post by: dylan.lauenstein on November 17, 2014, 10:21:40 pm

I have an 87 custom deluxe with a 305 that has a very annoying ticking sound. It doesn't do it at idle but once you give it throttle it starts doing it. Any help or ideas would be great!

Exhaust leak?

Or is it a mechanical tick like a loose rocker arm?

I can't find any exhaust leaks so far

Have you got headers?  If so, it could just be header slap.
