Oh man where do i begin. was it the 2 gallons of water in the oil pan, the misfiring and explosion of the cat to get it home, the stalling issues....

Anyways I have the heads off and am water testing the heads to see if valves bent when she drank the muddy water so if anyone has the size valves for the sohc on intake and exhaust that would be great. ive changed the diff fluid in front and rear, changed oil 2 times as of now probably going to change it a 3rd after 50 miles but as she sits, i have not checked piston rods for damage. anyone ever take their girl offroad and filled up every cylinder with water and has some hindsight to share?

 

Hydro-lock wouldn't bend valves, would make exhaust valves warp from rapid cooling
It does for sure bend connecting rods, you can put a straight edge across the block and measure piston height at TDC to find out which one(s) got bent

I would just look for a used engine
Any time you rapid cool metal parts they can crack, invisible cranks that will show up down the road at the worst time, lol, not that there is a good time

 

nooooo dont say that! so bent rod is the reason fuel was getting into cats? cause the fireworks display under my truck while having **** compression and them glowing red fuel had to get in there. but it ran just had **** power and it stalled alot even in 4 low limping. if the new valves and such dont fix this issue, next is an engine. i was just trying to avoid it because of the mileage of motor

 

If engine was running poorly that means it was misfiring, no gasoline burned in that cylinder, and that gasoline gets sent to exhaust system on every misfire

When water(any liquid) gets into a cylinder there is no issue until piston comes up on the compression stroke, both valves are closed at that time, the water will not compress like air will, this is called a hydro-lock, and something has to give way, it won't be the water, lol, so either the piston cracks or the connecting rod bends, or both, allowing crank to keep on turning
There is alot of power in the spinning crank shaft, 200 horse power, it pushes the 3,500lbs vehicle down the road, so if water got into the intake and into one or more cylinders while engine was running then pistons and connecting rods were damaged
Not a guess, its just physics/mechanics of how the system works

The valves are closed when the damage occurs so they don't suffer the pressure damage but cold water will cause warping of the hot valves
