Re: [Amc-list] Amc-list Digest,- Zinc oils/roller engine/scraper

[Davis Martin <martin-davis@xxxxxxxxxxxxx>]

Ken,
   roller engines have cams with roller lifters on them so instead of a flat surface riding on teh cam it is a rolling wheel and requires less lubrication so not as much zink is needed. Some engines have roller cam bearings also instead of the soloid Babbit material.
   A crank scraper is a part that fits close to the crankshaft and the rest of the rotating assembly to scrape the excess oil from it.

Hey guys, ?Thanks for all the? great threads and info on the oils with zinc. I will start using that wall mat pre 88 or the diesel engine oil in my pre 88 cars. $9.19 a gallon for the diesel oil is not bad, 1.39 is good too. I have been using fram filters for years and never had a problem?in 40 years,?but i do read the threads of how much everyone hates Fram.
ok for the non engine tech types here, like me, what is a roller engine versus non roller or whatever that makes the zinc not necesary?? is it overhead valve, versus overhead cam? Never took a motor apart so I hae no idea, but I may too to try sometime soon when i restore my dads 74 ambo 360, sitting for many years. what are are amc?engines-where is the roller thing??and what is a crank scraper? In quiring minds would like to know... regards.
and thanks,
