I have a load ticking noise, like a lazy lifter, however I've been told there

3.5 High Output

Ticking is different form knocking! Have a mechanic listen to it...should be able to tell if it's in the valve train or not...

sorry its a loud ticking, which I have had a mechanic listen to and that's when he thought carbon build up, so we ran cleaners in the gas, and oil, and higher octane gas, 3 tanks of gas later, I still have the ticking, and the only change has been in the start up in the morning, and after warming up, the ticking starts, and as i travel it just gets louder.

I do not think it is carbon related! Have another mech listen to it....may have to pull valve cover(s)...good fresh oil and the proper sae (type) may help..

THANK YOU

Anytime!
