Where was this engine sitting prior to you taking it apart? It looks like water filled up a couple of the cylinders. Those rusty cylinder walls do not look good.

What did you use to clean the pistons? I used a whiz wheel on mine but I couldn't get in all the grooves on the pistons. Yours look brand new. But I also used it on the block surface and it took all the old gasket material off and polished it up really good.

i used one of them wire brush wheels you can put on a power drill. worked great, i used the smaller version of them. yea the engine had been sitting outside in the rain. i mean alot of rain. the engine isnt siezed the main crank turns and the pistons move so im thinking of just haveing it machined cleaned in the cylinders, unless its fine to use the wire brush i mean i dont want to scratch up the walls, if i recall thats a bad thing. the rust is just kinda sitting on there its not a deep rust just a very very light surface type. but ya the pistons i was on it for about 30 mins and made them all look like that its alot better that what it was.

That looks much better. You want to use something with even less grit than 2000. And you want it wet if you are going to do it by hand. I would soak it just like i mentioned in the afore stated post.

So much for TDC. You'll have to relocate it.

TDC= Top Dead Center. Its a term used to describe the position of the No.1 piston at the top of it stroke.

But I have no clue what he is talking about, relocating TDC?? You got me......

And using a wire brush on the cylinder walls would be the worst possible thing you could do.

All I mean is your going to have to turn the crank until pistons 1 and 6 are all the way up top and then we'll probably still have timing issues.

Don't touch any mechanical anything inside the block. Especially the pistons. You make any type of mistake and you'll be ending up with piston slap wich leads to rodknock if not detected and repaired quickley. In any case you'll be rebuilding again basically.

Some of my slangs seem to throw people off. There's a bit of a clutural clash at times. It's nothing we can't work out.
