strange ticking noise at back of engine
 

when the truck is fully warmed up and only in either PARK or NEUTRAL when the idle is up higher i have a trucking noise coming from the back of of the engine and when i hit the gas pedal it does not gradually increase as a valve tick would so i know it isnt a valve and it will NOT do it in drive reverse 2 or 1 gear. any one know what this it? it only started when the truck was ran out of fuel and has to crack injectors to bleed the air out. truck has 200,058 miles as it sits and still runs very strong. any help appreciated

sounds like you didnt get an injector line seated back where it belongs...mine did the same thing the line on number six was a little loose

Wouldnt it leak fuel though?

mine sprayed a very fine mist on the firewall it took some lookin to find it originally i thought it sounded like an exhaust leak but after i cracked the hood i found that line spraying a little where the bolt on the line didnt get tightened

check ur valve adjustment

i thought of valves but it doesnt gradually increase when i rev it

check the valve adj

i have seen weird stuff with the valves either way it wont hurt them you cant over adjust

thanks for the input is there a chart where i can find the right adjustments

.010 intake .020 exhaust

thank you sir
