That's right.
When the 3rd gen Camaro came out they had a hood on some models that had a flap to let cooler air in when the throttle was mashed down hard. Trouble was, when the car was sitting and it rained or the owner washed it, water would leak through and get into the intake.
Then, the next time the engine was cranked over the water was drawn in, and on the compression stroke the pistons would hydraulic the heads right off the deck of the block.
Mack had about the same problem the last few years they used the real Mack engine. The intake manifold gasket would push out at the top then water off the cowl would run down into the cylinder head. The engine would not crank over with the starter so out came the chain & when it was pulled the piston pushed out the side of he block. I saw one that the hood was left open during a rain storm & there was water in two cylinders.
I also saw several times a truck would be parked under a roof down spout with the exhaust directly under the spout in a storm. I was able to hold the exhaust valves open on the hydraulic locked cylinder & bar the engine over to push out the water. I have seen bent rods when somebody pull stared a hydraulic locked engine. If the drive tires are skidding while pull starting there is more wrong than a bad starter or dead batteries.
Chevrolet bought a lot of engines for those cars, and also had a huge recall to fix the leaky air intake issue.
