I've got a parallel valve io-360 that i'm overhauling for my 8. It's got about 1000 hours since an overhaul that happened 30 years ago. I'm tearing it down because of pitting and a severely spalled lifter. I've sent all the internals out and have gotten everything back with tags along with a reconditioned cam and replacement tappets.
There's just one last thing to find out before it goes back together...
I see that the lycoming mandatory overhaul list does not include the pistons themselves. If they are re-used, how are they cleaned of all the carbon and lead that accumulates on them? I figured that if they were being re-used, then a place like Aircraft Specialties would clean and inspect them, but I don't see pricing for that on their website like I do for all of the other internal components they will refurbish.
I'd love to save $500 and not buy new pistons if I don't have to, but i'm reluctant to stick new rings on these things without knowing for sure that they're ok to use not to mention being cleaned.
So, the questions:
Re-use them or just toss and replace?
If re-use, how are they cleaned?
Is this something I can do myself, or should they be sent somewhere?
Thanks!
