Need ? No, but they do take up the slack from chain wear and stop the timing mark from bouncing around as much when checking it with a timing light.340 small block how do I know if I need a timing chain tensioner?most of my experience is building big block Chrysler's, building a small black is new to me.
I agree. Unless it's grocery getter, dont leave home without one!I Run one and won't build another without one.
Stable timing is a win!
Pics or it didnt happenMine had a raised ridge on it that the rollers rode on. With the side plates not contacting the shoe, there's no shavings to be had.
