Just put a new 418 in my Duster. I start it once a week or so. When it fires up you hear the normal valve trane noises. Will this eventually cause some problems over time? What I would like to know is there an oil additive I could add to the oil that would help the oil stay on the internal parts better ? Thanks for all advice.



I’m not sure what you mean by normal valve train noises. Do you mean when the engine is cold it makes a little extra noise at start up which goes away after the engine warms up? That’s a true enough reality for most any engine. Curious, have you totally ruled out loose valve adjustment?

I’ll include some links of some products and tricks that will help you optimize lubrication upon cold (dry) start up.

Ample amounts of ZDDP in this motor oil:

Also, consider an old tried and true method of lubricating your engines internal parts on the combustion side of the equation. This is done by adding a very light 500 to 1 ratio of TC-W3 rated 2-cycle oil to your cars gasoline, which equates to 1 ounce to five gallons. We all know that gasoline used to have lead, a heavy metal added to it back in the day as a means to cushioned and lubricated parts in the combustion chamber. So then is it inconceivable to think that a 2-cycle oil that is designed to not only provide a film of lubrication on parts in the combustion chamber but also burn completely and cleanly could provide similar results? This is somewhat of a controversial topic but one I’m going to give a fair shake. Check out the following link for more on this topic:

There are a vast number of threads here on moparts.com with the topic of Zinc, oil additives and the like, which is usually a very spirited conversation. Check out this link for an example of this:

I'll also provide a pdf. attachment that addresses flat tappet camshafts and Amsoil products ZDDP formulations.

Enjoy that new 418!
