Evrytime I take a motor apart, even after just a little while, the chain is as sloppy as a pie eating contest. So I tried the tensioner on my stroker 392 Hemi for the drag Week car. I was skeptical, expecting to see shavings of plastic in the oil and trenches dug into the plastic guides. But nope. Timing was steady, and when I pulled it apart there was zero wear on the tensioner guides. I'd do it again.
I used one on a 340 build but also used a crankshaft oil slinger and the oil dripper on top oil hole it was A-Ok when pulled down many years later
