Re: Restoring Rusty
and all the pistons out of the passenger side as well, and numbered
I realize I'm stamping them on the bottom part that comes off but I don't plan on having more than one apart at a time |

Re: Restoring Rusty
I took care to cover things up and tried my best to prevent debry from falling in where it don't belong

Re: Restoring Rusty
before and after honing pics
the mirror like finish is actually what you don't want when putting in new rings, you want it to be dull(ish) like the second pic |

Re: Restoring Rusty
yes I did get a ton done in one day, I wrapped things up late at night by de-ringing the pistons, and oh boy did I find two problems
but first the good side, the passenger side, all de-ringed |

Re: Restoring Rusty
things got a bit more interesting on the driver's side
two oil rings were broken, can you guess which two? remember the two middle chambers in that head #3 #5 |

Re: Restoring Rusty
no gentlemen I did not brake them whilst removing them off the piston, they were broken already that's why they would not spin at all
here's a closer look at #3 oil ring snapped in two |

Re: Restoring Rusty
and here is the broken oil ring of #5, this one broke into three pieces, a tiny small one if you look closely
I think we found our problem(s) folks! so lots and lots of work today, I can't believe I tore it all apart in one day so quickly like that, and I hope to put it all back together tomorrow can I do it? stay tuned... |

Re: Restoring Rusty
Wow - impressive amount of progress. Waiting to see the plan to address this. Better set of rings? Something you can do to keep the next set from breaking... Good luck getting it all back together today!

Re: Restoring Rusty
well after cooking the kids breakfast (yes I took them to IHOP - shhhh, don't tell the wife) I had an hour this morning to prep the block for the pistons, ie scrape the old gaskets off

Re: Restoring Rusty
First pic in post 4767
1- looks like you need to cut the ridge off the top of the cylinders 2- is that a mark on the crankshaft journal? What do the bearings look like |

Re: Restoring Rusty
I will have to take another look at the crank, when I examined it the first time, it looked good, bearings had normal wear, but I bought brand new ones anyway

Re: Restoring Rusty
If you could get the pistons out fairly easily, you can probably get away without removing the ring ridge. Theoretically, the new rings won't hit the ridge, or be damaged by the ridge. We hope.
I like the flex (ball) hone for finish better than the cylinder hone you used. It will still work either way, as long as the glazing has been removed. My block had 0.007" taper, and it took a bit of wiggling to get the pistons out. I got half-way through cleaning the pistons (Easy Off over cleaner works great - just don't let the cleaner linger on the pistons. Soaking in Diesel works well, too), and decided I didn't want to be here again in 5 years, so I had it bored 0.020". And balanced. And with a torque plate. And the cha-ching cha-ching for machining. Is this the original block?
