Hopefully Molecule and the oil gurus can step in here and recommend something here.
A little history: This Mack only has about 10K miles on the current cam. An expert mechanic mentioned that its exhibiting the properties of a bad cam already (popping sound in the air intake). This truck has be owned and operated by my father's company for all it life, with marginal maintenance. The cams are lubed by windage off of the crank and rods. Our trucks have always run a commercial grade name brand(what ever is cheapest in 55 gallon drums) 15w-40 diesel. The truck is a 10 wheel dump truck that sees equal amount of on road and off road work. I'm sure that the off camber operation plays havoc with the splash lubed cam (ie oil not always getting to the cam evenly).
In a last ditch attempt to keep it running (this is after a winter of repairs) we dumped a gallon of Lucas into the oil to see if it would help keep the cam lubed. We will also have to adjust the valves and hopefully that popping will go away.
Even if it needs another cam, this will be the fourth that the truck has seen with a maximum of 200K miles. My question is, is there a product that we can use that will help keep that splash lubed cam from grinding to a nub? I was thinking a super EP suppliment or something? The engine is very clean inside, however I was thinking of adding ARX to the crankcase for the positive effects of the esters (cleaning and EP).
