So if any one can distinguish between rod knock, injectors out , cp3 bad or something els that would be great , a little bit of haze out of tail pipe , and no blow by but vsry loud knock

 

My phone is trashed so thats why my post are subtle and usually spelt all kinds of fuxed up

 

Very likely an injector. The sound is rather identical. If you hear the knock up near the head area, then its likely an injector. If the knock is down low or louder in the oil pan. then its a rod.. Do you have oil pressure?

 

The oil pressure guage stays above 40 at idle , when it usually qould drop down to about 20 at idle

 

More likely a failed injector...........
