Possibly a spun small or big end bearing need to pull motor and have a look at least . if you still have the oil and filter cut filter open and look for metal in the element and strain the motor oil through a paper coffee filter but if its noticeable and you have a knock id definitely be pulling the motor . Sorry for the bad news

Slight knock is still rooted bearings - imminent bottom end death predicted.

Just the bearings mate.
Don't use it pull the motor or if not that way inclined tow it to a shop . That metal is throughout your motor The less its run and quicker its fixed = less damage = less money . It sucks but at least you have caught it before a catastrophic failure .

In your opinion guys , for the best result reliability power should I use a ej205 short block with my ej20k heads or just get my crank reground. Cheers
