You can try and get your insurance company to cover repairs. If it happened due to flooding and you were using stock intake insurance may cover it. If you weren't using the stock intake then just put it back on and say you were.

 

yea we were using a cai

 

really good info thanks!

 

I hydro locked my engine while running a CAI across a very shallow skim of water. I would say around 4 or 5 inches deep, yet the CAI managed to draw the water up into the cavity where the filter resides.

The article was right about usually bending a rod. If you don't attempt to restart the engine, the hydro lock might not cause any damage. But trying to restart and forcing the starter to bend the rod as it turns the crank, this is usually where the damage occurs.

I disagree with the statement in the article about it not being economically feasible to repair an engine with a bent rod. When I had my car towed after hy locking it, I pulled the pan immediately to look at the rods. I new the clack, clack, clack, noise it was making had to be a bent rod. Sure enough, when I got there, the rod was bent, I could see using a flashlight looking past the crank. I ordered a new rod from Acura and pulled the head, rod and piston assembly and had the local machine shop swap the rod. Total cost for my weekend repair, around $150 for rod and bearing. Sounds economically feasible to me.

I have put on 52K miles since the rod swap, and it revs out just fine, all is well. I got lucky and reused my old piston and rings, head gasket, head bolts, and oil pan gasket, with no problems at all.

 

can also hydro lock from liquid injection lol...saw it on water injection once.
