For that ticking noise try marvel mystery oil it works 1 quart all it takes smooth as silk and a little better gas mileage if you mix it with your gas used it for years its 100 years this year

Sorry I didn't your message earlier I did use some Marvel Oil added Soon after I did the work on my truck Not really sure if it helped a lot I think my cam and lifters are kind of worn out The motor runs really strong Other than the ticking It's coming up on its 300 big 1 It needs to be Taken apart and gone through But that's for future T Thanks for the advice
