Hey guys, I was helping my friend rebuild a 3.5, everything was going as planned but when I came to help today I noticed he left the pistons in a bucket to get rid of the carbon. He also but the rod's in there too. The rids have surface rust and the pistons ate cleaner. He says he didn't screw anything up, but noe I feel I like I'm wasting my time helping him. The Clorox created surface rust.. is it worth it to continue the rebuild. Sorry for the grammar, writing from my phone..

 

Put** and he left it in a bucket of Clorox (rods and pistons)

 

he should just run sand through it LOL

 

Rust on pistons and rods ain't a good thing. replace them

 

LMFAO. Placing steel in a strong oxidizer - pure genius.

 

i had a facepalm started just reading the title lmao

 

Guessing this rebuild is going to be an epic fail... so whata you guys think is going to happen? I think the engines going to work for 1k or so then its going to start to knock.

 

 

3ClO- + Fe3+ --> Fe2O3 + 3Cl-



Think I may have added an extra electron into that equation somewhere.

 

im far from an engine builder but even I know you dont do that.

 

I read the title...had to check out the thread....yikes.

 

pics or it didnt happen

 

In for pics.

 

Jesus..

 

Wow, really?

 

ill post pics rods look shot surface rust got much much worse, pistons look okay

 

It should not be that bad. Note that the connecting rods are always in a bath of oil inside the crank case. And, moisture is required to promote rusting which is not present (It better not be) in the crank case. I would suggest a nice wipedown of the connecting rods with oil and keep them aside for a couple of days and see if the rust increases. If you are overly concerned with the rust, just replace the connecting rods.

I used to work as a engineer on large cargo ships and we always have a little rust on the spare unused engine parts. As long as they are not bearing surfaces, we clean them thoroughly, apply oil, and install them. Granted that the large engines have inspection doors / windows to the crank cases, so, you can check the parts periodically. On cars, it is not the case.

Finally, it is your call. Good luck.


Also, can you just check the material of the connecting rods (cast iron?)

 

 

Found it. Like this?

Damn your ninja editting.

I think this wound up being a joke. I could be wrong, though.

 

Im old school when it comes to those ninja edits lol

 

While it's an incredibly stupid move, I really don't think minimal surface rust on the connecting rods will cause a disaster.

 

When I read "clorox" on the thread, I thought got to be some kind of idiot to do something to put metal in it. There's a stuff to clean carbon, called Part washer or cleaner, it's the same stuff they used for carbuetor that get soak in a basket, to remove varnish and carbon. but CLOROX? definitely setting it to rust and early part failure. Definitely replace the parts, I wouldn't take any chances even though you have some rust but it definitely changes the metal molecule structure thus weaken it.

 

should have used snuggle.

 

man i ve heard of tide but never that its almost like an hot tank bath at the machine shop, but wow wonder where he got his info from ?

 

You ask if you're wasting your time helping him...

Part of me says "be there, get the experience and wrench time in," but there's another more realistic part that knows he will blame you when it fails because "you tightened that one bolt on the power steering pulley, now it threw a rod."

 

So the Audi thing is clearly a joke, but I don't think this is. I can understand the logic behind the move, at least, whereas I don't think ANYONE would pump sand into their engine.

 

Is the damage too bad to have them glass bead blasted?

 

OMFG - just pull up your panties, clean up the surface rust, put new rings and bearings in it, and put it together. Most likely just surface rust, and it probably won't dramatically affect the engine life at all, as long as you clean it up before you put the engine together.
