So the RAM has a annoying knock in the motor! I'm pretty sure it's a stuck or loose lifter. how can I tell for sure? Two ways I've heard of: Push the rocker down towards the lifter. It should not budge. And watch for oil outta the pushrods. I just don't wanna blow a rod out if it is a crank rod bearing.

 

Pull the valve covers, wiggle the rockers, see if anything is loose.

 

Well decided to replace lifters as that is definitely where the noise is coming from.

 

SeaFoam it!

 

Already did . No difference, and I run SeaFoam regularly in my oil too.

 

Since this has divulged into a SF thread, I will likely run mine again here in a month or so before I change it.

 

The only time I've ever noticed seafoam helping a motor run better is when you pour it directly into the intake of a hot running engine (being very careful not to hydrolock the engine) and when the product hits the combustion chamber it flashes to steam blowing carbon deposits right off the head, valves and piston. Worked really good on a heavily carboned up motor. Oil: I've had great luck with running 1 quart of kerosene in the oil immediately before an oil change. Run it for fifteen minuted like that (NOT DRIVING) and then perform your oil change. Fixes sticky valve train and did great at dissolving sludge. Best example I've had is my little fuel saver Saturn SL1. It had a clattery valve train, possibly due to a sticky timing chain tensioner (it's hydraulically driven). Did just as I explained with the Kerosene. Runs silently now. I also noticed the brown deposits on the dipstick that've been there since I bought the car in 2008, wiped right off when checking the oil level That was 2 years ago, still going quietly at 157k.

 

I run SeaFoam in the oil to help keep it clean, and the big bonus most people don't know: It helps seal piston rings, helping boost compression.

 

That's what I use Lucas for. Again, my Saturn as an example, blows blue smoke under load in normal conditions, and burns oil in general. 1 qt of Lucas in the place of 1 qt of oil every oil change and it doesn't burn a single drop of oil for about 3500 miles. That stuff is amazing. Like you said with the seafoam, it seals the rings and there's a noticeable increase in pep and acceleration when it's got fresh oil in it. Of course you'll only notice it's effects on a worn engine. A properly running engine won't be affected by such additives other than increased longevity.

 

ya know, seafoam in the oil could also cause problems... loosening debris which find their way to the sixteen tiny trash cans those push rods cradle in, for one..
