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 |

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
Oh me. You're elbow deep now.

Re: Restoring Rusty
Dude, your energy amazes me. You get more accomplished on your rig in one day then I have on mine in the last two years. Thumbsup man!

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!

The guy used to own a machine shop and said they seal better in less than perfect conditions such as mine. Summit description reads: "These OE-quality Sealed Power cast piston rings are made from ductile iron and are specifically designed for stock rebuilds." and they were made in the U.S.A. - Bonus! |

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
Fun Level: -2 |
Re: Restoring Rusty
That coolant you found... Is the block cracked?

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
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? |
Re: Restoring Rusty
It would be wise to get that cylinder head magnafluxed, that buildup on the spark plug is from coolant.

Re: Restoring Rusty
Yea, it didn't seem like coolant to me, I think I mentioned in another thread it might be rings.
As much as you have in exhaust gaskets Gregg, you could have just got some better fitting headers lol |

the intake gasket was the worst, it was stuck around the water passages real good, I can't recall if I used any adhesive around these ports or not

went with these standard size Sealed Power cast iron piston rings on a recommendation from an old machine shop old timer, he said these seat better than the stainless steel ones or them fancy ones

'Cause if you liked it then you should have put a ring on it

Re: Restoring Rusty
Dude, you are prodigious! I can't believe how far you got into that motor in such a short amount of time: Let's see. ..wife's gone, the football game is over, kids don't need to eat til six thirty. ..why don't I pop the top off the motor and have a look-see. Hmmm, still got some time. ..I'll pull the pistons out too.
Dang! |

well by lunch time, so three hours later the pistons were in and torqued down to spec, I'll be honest with you I didn't think it would take me this long to drop them in, but hey I'm a One Man Circus Act
so here's how we did it first I do NOT recomment this piece of junk adjustable piston ring compressor, but hey it's what I had I bought it back when I was young and stupid, now Summit got them non adjustable funnel tappered ones which are awesome |

we also went with Sealed Power brand con rod bearings but these were from Mexico, I dabbed these in oil to give them some stick-to-it-a-vness

... the others went a bit quicker
I did them in numerical order - just because, but making sure I could fully rotate the crank by hand after each one |
