Problems starting 6.2

[levib]

Last weekend my 6.2 blazer took a dip in a little stream. Stalled out, but started up again in a few minutes. Drove it home ok, let it run for a while, and it still started up later. But now it wont start at all, it just turns over kinda slow. I charged the batteries, changed the starter and still no luck. I'm out of ideas. Any suggestions?

Check your oil, if water got in the oil you might have a problem.
If in doubt dump the oil and put new fresh oil in it and give it a try.
You might also want to try to take out eh GP's and see if the motor turns easier if not you have a problem internally from water getting in, like water washing off the oil off the bearings and they are seizing...

Thanks for your help. You were right, I found water in my oil. I changed the oil and got lots of water and some metal flakes. I tried to start it again, still doing the same thing. What would my next step be?

Well the water I was sure of, the metal flakes means it's worse than I thought.
You were able to start it when you were in the water so you ran it with water which cleaned the oil off your bearings then ground the bearings down until all the soft metal wore out and got to solid metal and caught your crank.
You pretty much are done here you need bearings and either another crank or have it ground and renitrided.
If I were you, and I have doen that already when it happened with me, find another engine and drop it in, much cheaper.

And I thought running it for a while would help get the water out. So if you get water in the motor, what do you do? Just change your oil right away?

Well you get out of the water, get home or the closest you can to a plce where you can change the oil and change it, yes.
The longer that water sat in the engine the worse it got.
And don't think I learned that from the books, it happened to me.

Yes, water and engines....I remember that....might I suggest

www.govliquidation.com

I keep my eyes on that place, lots of cool stuff but everything seems to sell for way more than I thought it would.

I'm trying to find someone on here who has an extra 6.2.
