Mods, can you sticky this please!!
Recently I had mine hydrolock due to water dripping on top of my intake manifold and somehow getting into the engine and destroying it. I would just rule this out as one random bout of bad luck. But I've been floating around the forum for a little while and I have found at least 3 other threads with people having the same exact problem. I figure I could have avoided an entire engine replacement if I had seen a thread about the leaky cowling.
Just putting this out there.. modify/move it how ever you want

It is extremely unlikely that water on top of the motor
is the cause of water in the cylinders. More like, just
the remaining evidence of a big splash that got sucked
up through the intake path as well.
If there was a significant hole in the top of the intake
you would know about it.

it was parked in the driveway on a clear night. Was running strong when I parked it. It rained 4 hrs before I tried to start it. The only part under the hood that was wet was the right side of the intake manifold. Filter was dry, throttle body was dry, maf was dry. Only one cylinder hydrolocked #8, which is on the pass side at the rear of the engine..

This is not sticky worthy. There is no "common" problem with LS1s hydrolocking due to sitting in the rain. Thousands of people here even wash their engine bays (myself included) without issue.
Obviously, something happened to your engine. It's not a design flaw though, otherwise this problem would be as common as broken power window motors.

Was your engine warm when you pressure washed it?
I believe that was discussed in one of these posts..

Given that, how did you determine that the engine hydrolocked for sure? Could have been a bad bearing that coincidentally **** out right then.

I pulled the intake manifold, #8 port had some water (not coolant) inside it. After I got the intake out I discovered it too had water in it. There were no loose vac or sensor connections at the back of the manifold, no cracks either. The night before my idle was smooth and not high. The power was the same as it was before, it easily broke lose on pavement at 45mph or less. I never went above 2k before it was at operating temp.

I don't get it either. I even checked to see if the coolant line running through the TB was the culprit. Unless it somehow squirted past the intake valve and up into the intake. I seriously doubt it cracked the valve, and I'm even more doubtful that, that much water could get back into the intake that way. I already put it back together so I could get an estimate from my insurance. So it will be a little while before I can pull it again to look at the heads.

IIRC, there is a possibility that water leaked through the fuel injector housing. Based on what I read, the rubber gasket around the fuel injector number 8 can get dry and cracked, thus allowing water to go in.
I am just re-stating what I read a few weeks ago.

If thats the case he would of still had a vaccuum leak prior. If the leak is letting in water, than it sure as hell is leaking unmetered air... Wich would result in surging, high idle, or a miss fire. The car would not run perfect, then just randomly hydrolock after sitting in the rain lol. Were missing a piece to the puzzle!
