I am at the end of my tether. I bought a motor interstate which was claimed to be mint condition.
I got it delivered at which it was the wrong year model. So I sent it back as he sent me an 01 instead of an 04. Just got him barely to accept and agree to send me what I paid for an 04.
It arrived and looked good but was difficult to turn over by hand. So I squirmed some oil in each spark plug cylinder and tried again.
That's when I noticed brown water coming out of one of the spark plug holes. It must have been sitting in the rain or something of which the wrecker denies. And doesn't know how it got there. I decided to pull the head and this is what I found. Two cylinders at the rear opposite sides filled with rusty water.
Upon wiping them down and getting surface rust off I noticed score marks on four of the eight cylinders. Some I can just catch my finger on.
It's meant to be a low km block. Would you run the engine with these marks? I can just catch a finger nail on them. It won't hang on it but will grab as I run it over the marks.
I get the distinct feeling the wrecker doesn't want to help out.
No I bought it doing bank transfer. The wrecker keeps saying he doesn't know how water got in there and to just run it. Obviously he doesn't want to replace the engine. Annoying that I paid very good money for a supposedly mint condition engine.
When I put new rings in do I have to machine them to fit? It will be my first re ring of a engine.
I honed 0.003+ and reused the stock rings.. runs great, no blow by, no oil burning and no piston slap.. and this engine was way worse than yours, she had water and rust in every cylinder..
I'd yank it apart for a good inspection, give it new bearings and rings.
It you use this without overdoing it, you should be able to retain stock sized pistons & rings:
I have a ton of these at the house, these do fantastic work and cut alot of expenses down of having to take it to the machine shop. Biggest advice I can give about these is, make sure you use the right speed drill, use a honing oil or cutting oil like TAP MAGIC, and make sure you do it consistent across all cylinders no more then 10 seconds at a time, you have to be quick enough with your up and down strokes that you get a good 45* cross hatch, if you go too slow it will be too shallow, if you go too fast it will be too steep. It wont kill you but 45* is ideal for proper ring seating and oil drainage. It WILL take off alot of material if you overdo it, and you will notice it in your ring gaps. You also have to use the right abrasive grit too that is recommended in the service manual. Some people prefer a 220, some people prefer a 400.
It's only done 72000kms.
Im in Australia hence the kms.
So very low. I think maybe it was seized from sitting so long?
First time doing an engine. How hard is it to do the bearings?
Should I get a shop to hone it or will that take out the marks I can feel?
Generally speaking if the scratches catch your nail, it needs to be bored, not just honed. If this is your first engine build, take your time, and read up on how everything goes together. None of this is particularly hard, but following torque specs and measuring clearances with the proper tools is KEY to success.
So can I hone with the above ball tool, or do I need the three fingered Honer? What then do I do for rings. Bigger rings? Do I have to modify the rings?

If you use just a hone, you keep the factory sized rings, you wont need oversized, but depending on how much you remove with the hone, will determine how your ring gaps will be affected. I'd recommend the ball hone vs the 3 stones, as they produce nicer results.
Be aware that there's a few particularities about these engines. The head bolts cannot be re-used. There's a oil galley by-pass above the oil filter....
Buy yourself a good book about these engines. NOT a high performance build book, they assume you already know how to build them.
