engine knock

[souhradaj360]

Slight rod knock started last week. Very noticeable on cold starts, but seems to go away after warming up or higher rpm. I read a vaccume leak could cause this, anyone have any ideas? Or should I start looking for a 6.0 to swap? I can pick up a used on for $175.

A vacuum leak would never cause a rod knock. There is no relationship between a rod knock and vacuum leak. If you are sure it is a rod knock and not something else. Yeah you might want to look for a motor.
