Possible Rod knock?


Recommended Posts

Hey guys and gals,

I'm having a hell of a time trying to diagnose my 99 Legacy B4 twin turbo motor.


I'm hearing a knock, it isn't load and you can barely hear it.


The spark plugs were changed about 2/3 months ago, I was told to check the gaps but I'm sure sold that, that is what it could be.


I changed the oil to 10w-40 and I put awhole bottle of Lucus Oil treatment.


Still knocks, I used the famous screw driver to block trick and I hear the knock in the back 2 cylinders.


I attached a video. It sounds loud in video but it isn't that loud.


Can anyone help?
