Hey I have a light but loud tapping sound coming out of my 305 Tpi. It sounds exactly like a loose/old lifter. I was just wondering if there was anything else that would cause this constant light tapping (fuel injectors?)so I can figure out exactly what needs fixed. Thanks for any help.

 

Pull your valve covers, check your rockers. Also, get a long screw driver and put the handle bit up to your ear to try to isolate the tap. Does the tap get louder with rpm/load? If so you're probably looking at an exhaust leak.

 

The tap does not get louder under higher rpms just speeds up. Its defintley a mechanical sounding tap not the typical leaky exhaust sound. So I guess that narrows it down that it has to be one of the rockers.

 

I had the same thing too man, it went away tho somehow on its own...its would come and go, very slight tapping... sounded like it was comming from passanger side valve cover... havent heard it in about a month tho...infact after giving it some gas it would go away

 

I would say pull the valve cover check the rockers. may be a bad lifter

 

Yea mine started a couple weeks ago and has not gone away at all. Ill probably end up pulling the valve covers and trying to figure out which lifter it is..which kinda sucks because I just put new valve cover gaskets on a month ago and now have to tear it all apart again.

 

I was ganna pull mine too, I decided not to because it was so unnoticable and and barly comes.. but If u do keep me posted im ganna add u

 

ok I might eventually pull it thanks man
