4.7 cold knock/tick
I have a cold knock on my 2000 dodge durango. It only lasts for 30 seconds, but it is annoying as hell any ideas? oil pressure is good. oil is changed every 2500 to 3000 miles. i use 5W30 oil and the filter i use contains an anti drain back valve. i have been informed that the noise is the hydraulic lash adjusters building up pressure, and that it is not harmful to the engine. I want to know if that is true or not. Any ideas? I welcome your answers!

no im almost 100% sure the manual calls for 5w30, but either way i run whatever the manual recomends,
and i forgot to mention mine is only there when it has been sitting for a while, like overnight, or during school, if i park to run into a store for 10 -15 min its not there when i come back

This is proally gonna make the die hard non-additive peeps hate me=Lucas Oil Leak stopper =works good for that lil knock especially if it's a high mile engine..I use that and also z-max oil additive.Use the z-max first and then add the lucas and add both with the engine running and then drive atleast 20mins to circulate itand make sure you do this aftewr an oil change and supstitute the lucas and z-max for one quart of 10w30.and and make sure you prefill the oil filter atleast 1/2 way..good luck and I'd love to hear if any one has had problems with z-max or lucas products

Im kinda thinking it might be what Hydrashocker Mentioned, after closely examining the symptoms i am starting to believe all my little "Quirks" are coming down to just Sludge. Hesitation/oil consumption/coldstart-tick/non-synthetic oil with this much mileage
hmm.. so now where do i start with this repair?
