Weird noise @ 2k and 3k RPMs
ej20g short block
ej25d heads Hey guys, just recently started hearing a weird knocking noise at 2k and 3k rpms... It goes away before/after these rpms and it gets quieter when at WOT... I feel no power loss and I can't figure out what it is... My question is: Isn't a rod knock supposed to make that loud knocking noise throughout the RPM range and have massive amounts of power loss? Thanks for any and all input.

That rev range is typical for rod knock. Is it louder when the engine is hot?
