Rod knock?
:evil: Maybe this post should be in the angry venting category...???
So I was helping troubleshoot a SBC problem over the phone Sunday evening. Sure sounded like a rod knocking - but it was over the phone... I wanted them to check the valves but they were going to pull the engine instead.
Today the knock was quieter and then went away after revving the engine a little bit???
Now I hear it's running fine and that they did check the valves - one lifter was stuck up??? I call BS! The engine would be backfiring one way or another if the valve was open. How can a lifter get stuck upward after doing a carburetor swap?
Anyone hear of knocking "going away" the next day?
