With all the flooding that plagued Indiana this spring, I was unfortunate enough not to see the road flooded.
By the time i crested the hill and saw the High Water sign 20 feet before the water it was to late.
I tried to hit the clutch and key to kill the motor, but i think the water did it for me......
I'm sure it tried to hydrolock.

There's no oil showing in the coolant. There's no coolant showing in the oil.
But it's got a bad ticking type noise that seems to be coming from the top.
Also it seems to be surging from about 900rpm up to 1700rpm at idle.
In gear it wants to idle around 2000rpm.
The strange part is it's not showing an engine code, and my AFR's are still running between 14.8-15.3 cruising down the road.......

Bent Valve?
Lifted the head?






If you can't fix it with a hammer, you've got an electrical problem.

Start with a compression check (180-200ish psi I think is the target, and +- 10% or so between cylinders), and make sure you don't have a vacuum leak somewhere -- water rushing into the compartment could have knocked something loose. A vacuum leak can cause it to idle funny just as easy anything else.

Ticking could be a collapsed lifter, but it'll be hard to tell that for sure without taking the top end apart. I don't remember if ecotecs are hydraulic lifter or not, but probably are -- which could potentially save you from bending a valve at the cost of collapsing a lifter.

Sleeper style, they don't see it coming that way.

that's the plan, but first i need to get a friends grand am out of the garage......

Yeah I would compression check and report back.
