Ticking coming from engine

So a quick background story: I was wheeling, flooded the engine, engine wouldn't start. Drained water, runs now just with a ticking coming from the engine. Thought it may be the lifters sticking due to water still in oil.
After getting ALL of the water out its still ticking. No bent valves/rods and nothing is cracked (that we can tell). Also while running after giving it gas the idle drops very low (100-200 RPM) and then goes back up. Any ideas? I've been without my ZJ for 3 weeks now. I'm having serious separation issues and need her back on the road asap! Thanks in advance!

Did you try putting in new spark plugs?

Could it really be as simple as that????

I did however replace the plugs/wires not too long ago. Could they still be a factor?

I'm honestly not sure, but if it was my ZJ I would definitely do an ignition tune-up if I sucked in water to the point of stalling. Could be fouled plugs causing bad detonation. Is your exhaust manifold cracked? That could cause a ticking noise. Otherwise it's probably the common lifter tick.

No the manifold is all fine. I'll take a look at the lifters when I get a chance

Don't get the evap solenoid click confused with an engine tick either. When I put the 5.9L vents on my hood, the sound is a lot more audible now.
