Default Re: Noise in my new 29 a engin

STP is not a lubricant it is an additive and so is Lucas. So, do two modifiers make a lubricant, not likely. Today's equivalent of 600 W is known as Steam Cylinder Oil and you will only find it at the local distributor, not at the auto parts store. Do a search here for "600 W". Remember, when your back on the road with your ears on, the consensus on timing was NOT all the way down. That is the sound of the engine crying and saying; back off, that's too much.
