So doing a valve adjustment i found #3 intake to be very loose. I started to adjust and then found this. Why/how did this happen?
Also, why are my leakdown tests consistently 20% leaking through the case? Rings? I did it cold and the engine looks to be rebuilt from how clean the inside of the heads were.  |

That stinks Bob.
So I put a good used one in its place. Torqued it back up and move o to cylinder 4. Im hoping what I found here was a rocker shaft nut and nothing more. The nuts on shaft 3 are copper, not the stock ones. I believe the PO said he had to fix a rocker on number 3 lets hope this is the only hardware that got left behind  |

I would tear down rocker gear on both side and do a full R&R with everything done right. |

(IMG:style_emoticons/default/agree.gif) The pushrod wall material is pretty thick, but I'd always have a little voice in the back of my head questioning their integrity. It's just one of those parts that if it were to fail it would rain a lot of debris into the heart of your motor. |
