What to look for after water got into the motor

At some point last august my motor sucked up a whole bunch of water through the intake, and naturally it started to knock very bad. I've finally came around to take the motor apart. But this is the first time I'll be doing such a thing. What are some things you guys would look for? I've already removed the valve covers and the intake. Under the valve covers everything looked great. But under the intake there was a whole bunch of mud as well as dirt. Also when I dumped the oil there was no metal in it. I plan on taking the heads off over the weekend. Thank you for any advice.

Just imagine how a bent rod would look in a motor right now, it can wear out the piston skirt or cylinder wall, and can cause piston slap. Even more likely, if the rod is bent it's a bit shorter which means the bottom of piston is hitting crankshaft counter weight.
The knock could very well be the piston hitting the crank.
also, if rod is bent towords the front or back of the motor, it can lead to wearing/grooving the rod bearing

You'll just have to get it apart on a bench or at least pull the pan to see.. The the decisions start.. ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Ive fixed a couple out in the woods in 4x4's that got drowned. Replaced the rod,piston and put it back together.. It wasn't perfect but it drove out... I've also pulled the piston and rockers for the bad cylinder and drove them out.. so a hydro-lock isn't necessarily fatal..

I'm hopefull that my motor isn't completely gone because it was still running completely fine , there was no stuttering, no misfire.

Between school and work I just never really had the time. And then the weather got bad and I dont have a garage. And I was kinda intimidated with taking it apart. But it finally started getting warmer and I figured what the hell its sitting anyway I doubt that I can make it any worse now. You think this motor is unsalvagable? I was hoping that I might be able to rebuild it?

Hey Vlad, do you really think Moekluse meant bent pushrods? You should check your CONNECTING RODS if water damage is suspected.

If you can take the oil pan off and and can get to the rod bolts, that might be possible.

It might be, but that depends on what kind of vehicle it's in. 4th gen Camaros, for example, the engine is far easier to drop from the bottom of the car.
