Is this worth fixing???

[doghunter9]

Pick up this motor for basically 20 bucks.

It is a 84 super 65 model e65rwlcrs

I was told there was a pistion gone.

compression test cold
#1 0psi
#2 58psi
#3 60psi

Not good, so I tool off the head and found a damage piston in #1. is this worth the work, and parts $70 pistion and rinngs/cyl, and gaskets.

also look at the pics can I get that carbon of the cyl wall with out damaging it?

if so what is the best method?

I think for what you would have into it, it would be worth every cent of it...then again I would love to dump my 35 for a 65!!! If you dont plan on using it, fix it up and sell it for a real nice profit!!!!

as long as you dont have to do a rebore on the motor, I would say to change out the piston and rings (rings on all cyl, the other two holes dont look healthy on compression) and see how it does. with what you would have into it, it would be a good unit either for your own use, or to sell at a tidy profit once running

how much damage is accepable on the cylinder wall. there is some but very little as you can see in the pictures.. how do you now if boring is required, and is honing really reqired?

Also how do you get the connecting rod caps off they are 12 point but the sockets won't fit in there.

I would accept ZERO damage to the bore. If you are going to go through the trouble of replacing the piston, if there is any damage there, it will quickly eat the new one. Honing is definitely required after boring as it sets the rings up for a proper wear pattern. Given the low compression in the other two holes, I would rering them if they check OK, and let it go at that (just hone and rering). Boring will be required in the top hole if the damage exceeds what the machine shop thinks that they can safely hone out, without causing the cylinder to go oversize (this would also eat the new piston)
