This is #2 on my 5.4 that I'm building and am needing opinions on how bad this is. I think it is beyond honing, probably 10 over

 

Well with out seeing it is hard to tell how deep the rust is,but you are probably right.

 

I think it will be fine, take it to the machine shop and see.

 

Lots of honing and larger sized rings.

Go and use a drill hone with a coarse set of stones, then go to med. and fine, remember lots of oil. I usually then go to a fine ball hone and a brush after that. Take your time and keep speed down on the drill to get a good angled pattern. Keep in mind that a hand drill hones does almost nothing comparred to a machine shops hone. You have to be going at it for atleast 15 min in one cylinder to make a difference noticable on a ring gap.
A machine shop may not tell you that it can be done, in order to sell you a bill of goods on an over bore.
Also I dont think any machine shop would hone without removing the entire rotating assembly, which will cost you more $$$ on fasteners. Do it yourself and save that extra $$$ Then if you find that it's no good, you will atleast know that your not throwing money away.

Thanks for the info lowflyingbird

 

what i would do very first thing is take a rag with wd-40 or similar on it and take the surface rust off and see if the metal is pitted that will give you a better idea of where you are at the pic just looks like surface blooms if that is the case then you are ok but if there is pitting you may be in for some work

 

Hone and go. I would not evan remove the piston but make sure you wipe it good after (turn it over a couple of times and rewipe) and a light coat of STP oil treatment for start up

 

DO NOT I repeat DO NOT touch that engine until JBREW approves

 

ummm....




what????
