Blown k20z1 engine Cold air intake



This is what happened to a 2006 Rsx k20z1 engine that sucked up water from a cold air intake. One rod #4 cylinder out the oil pan and rod on #3 cylinder out the side of the block. The picture of the piston and rod is what is left of #4 piston and rod, the destruction of sucking up water and hydrolocking your motor with a cold air intake. This is just one of a bucnh of blown engine I have seen ever since the Rsx was made and the cold air intake invented for the rsx. The total parts and labor cost to repaired that vehicle total out to more than $10,000 dollars. I hope gaining a few horsepower is not worth the havoc of a blown engine. Short ram is the way to go on the Rsx because it doesn't like water at all.
That does suck.
For those unaware, you would have to almost completely encompass the filter in water for this to happen.
The key is avoid huge puddles, and if you have no choice, roll in with the motor off and in neutral.
Be careful, use your head.

did you run into just a little puddle or something bigger? just wondering cause i run a cai, and sometimes i run into small puddles and nothing happens. sorry for the loss.

Hydro locking occurs when the end of the inlet pipe is submerged in water and the water is sucked into the engine. Driving the vehicle in rainy conditions is not enough to cause a problem unless the vehicle submerges enough that the inlet end of the pipe is immersed in water. Rain impingement on the filter will not cause a hydro lock condition.

This happen on a rainy day and the customer ran into a puddle of water, he had removed the plastic cover in front of the bumper where the foglight should be. It don't need to be submerged to lock up the motor, if you enguff more water than the area inside the combustion chamber when it on the compression stroke while an engine is still spinning it will lock the motor and in severe case the rod break and tears up everthing inside. When the piston is at top dead center and all the valve is close there is only a small area for compressed air, if water take up more than that area then there is no more space to compress. Something gotta give after that, either the piston or the rod. If the rod break and the engine is still spinning it will turn into a chain saw a wack everthing inside of it.

2 years ago, we had a MAJOR down pour. it was soo bad that when i was driving my 93 prelude around with the wipers on full speed, i couldnt even see. i had to open the window to stick my head out to be able to see. water was able to seep in through the doors and i had a bad mold problem for a while. my books and stuff that was sitting on the floor of my car got wet as well.
i was glad i was boosted because if i wasnt, i would of had hydrolocked for sure.

I will have the picture of the cylinder head on soon, It will blow you guys away seeing how it look. Just because this guy remove his foglight cover doesn't mean that if you run the cai without removing the foglight cover make you less prone to a hydrolock. Last year I put an engine in my friend 03 rsx-s with aem cai, he blew his engine up from driving on a road that has uphills and downhills on a bad rainy day. On the way going downhill the was a large pudding of standing water and the car dive into it. The motor did not lock up but the rob broke and the piston came up and bent all of the valves, the rod kept spinning and crack the sleeve. This was less severe and the head could be saved. This picture of the motor on this thread is less fortunate and nothing could be saved because it was driven or awhile before it locked up. Note the large amount of metal shaving, I could not find the pistion pin, it was totally destroyed.
i live in nj it rains i just dont go through puddles the roads are curved so the left lane usually dosent have puddles.. U realli do need to go through a decent amount of water to lock.. jus be carfull dont floor it through puddles to be cool

Labor is a major part too, not just parts, unless you can do it yourself than you can save crap load.

But seriously, though, damn, hope this is avoided by all CAI people out there.
