325_driver 422 Report post Posted March 1, 2019 Wondering if anyone could describe early symptoms of big end bearing wear. 220k on the clock. Engine makes a slight rattle under load, like If I put it in a lower gear and accelerate it up a hill. No rod knock noise though, I know what that sound is like. Is the crank usually un harmed at that phase? Thanks! Quote Share this post Link to post Share on other sites
