| RE: Engine Break-In (289) ? |

Diminished performance and the valve train noise makes me suspicious that you may have a cam problem, Greg. I don't like going to the throat right away but it is generally recognized that as long as your tune up is right and nothing has changed then it's probably your cam. Engine performance generally improves as the parts wear in. You should not have to re-lash the lifter preload so if it wasn't ticking before, then it shouldn't be ticking now unless your lobes are going flat. The exception here is that your rocker stud lash nuts are worn and they are starting to back off. If that's the case, then you could and will suffer the ticking and the reduced performance as well as some potential destruction of the lifter if the plunger has exceeded the plunger well and popped off the retaining clip.
But you first need to ensure that your timing and carburetion are working fine. It's fairly common for the points to close up a bit and the carburetor to pick up some debris in the fuel line. And, as you've already done, ensure that nothing has come loose. As to the head bolts, it depends on what head gaskets you used. There's no harm in checking the torque but I don't think you're going to find the solution there. |
