yes, thats right.
any idea you know about it?
when i driving and i feel like a *POP, POP, POP* hard to acceleration during city.
but highway went to good but still noise.

So the engine was able to run on it's own, with no noise before replacing the fuel injectors?

i was repair fuel injection o-ring kits. somehow i was start but there stuck like a lock becuz of flood...so, waiting around 10 mins later...i start again and there got a noise lately.


Hydro-lock is the nail in the coffin. :-\ This probably means rod bearing damage. Piston and/or wrist pin damage is also possible.

Pulling the fuel injector wires one at a time while the engine is running may make a change in the noise. But it looks like you get to pull the engine out and replace the block at the very least.

You can check the valve lash before tearing the engine apart in case there is some sort of coincidental damage like maybe a spring has broken or if a guide has slipped and is holding a valve open.

rod knock. if it hydrolocked with fuel, you may have damaged the rod bearing or bent the rod on the flooded cylinder.

Here's my happy rod bearing in my outback.

I initially said that it was a spun bearing and I stand by that. The hydrolock is the death of the engine. You probably bent a connecting rod at the same time. Let us know what you find, but that block is now a paperweight.
