Funny you mention it. I took my egr off 2 days ago and cleaned out the ports because I had begun pinging under a load. It was clogged pretty good. Verified egr operation and put it back on and no more pinging.

Honda 2.2 Injector knock
- Thread starter harrycalahan
- Start date
How many miles on it.
Knocks when cold, now under load..... Main or rod bearing about to go bye bye. Piston slap has its own kinda noise.
Injectors will tick, maybe even "loudly" but its not a knock.
Shoot some video and post it, let's hear it.

injectors will tick but the knocking could have been caused buy one stuck open or closed....sounds like you might have a spun bearing
It sounds like a rod knock but its on the top end. 278k miles. Its a tight motor though. Rod knock/bearing knock typically gets louder as the engine heats up and clearances increase/oil gets thinner. At least thats been my experience with rod knocks. My engine has been doing this off and on for about 6 months or better. Only yesterday it did it most of my 30+ mile trip into work. I drove it home last night from work and it didn't make a sound, even cold. Thats why the injector theory peaked my interest because nothing else really makes sense. I can try shooting a video with my phone. I'm not sure how well it will pick up the sound though.
Ya I'm familiar with the ticking the injectors make when they're firing. Thats why I was shocked to see people saying they can make a "knock" sound. I don't see how an injector can make this sound but I've been fooled many times before.
smell the oil..gasy smell could be one hung open..but if it doesnt skip or run rich????
the knock could be it leaning out due to stopped up or not firing properly..slightly louder than spark ping
Yep. You don't even know its idling and I get 30mpg. For 278k miles, you'd never know it. Other than the super loud knocking sound when its cold and the shot interior lol.
that sounds like a rod knock
Well, my thinking is its taking place in open loop on a cold engine. Everything is cold (cylinders, combustion chambers etc) and its got extra fuel. This sound is not a pinging/detonation sound either. It literally sounds like a hammer hitting my block lol. Somebody come and go for a ride with me. I'm totally baffled with this.
