yact: i just screwed up my car

[BHeemsoth]

i have an 89 ramcharger with a 318 engine. Today i drove through a deep puddle and now my car wont start. It cranks fine, but wont turn over.

Any ideas on what may have happened? ideas on solutions?

 

[Mandos]

A deep puddle? How deep was this 'puddle'?

 

"Turn over" and "cranking" are the same

Your igniton is wet, spray the wires, cap and rotor with WD40 and try again.

 

[BHeemsoth]

approximately 2 feet deep.

 

[iamwiz82]

How fast were you going? Did the engine shut down when you went through?

 

[Bulk Beef]

2 feet deep is a pond, not a puddle. Do like Roger said.

 

If he drove fast enough and the engine sucked in water through the intake, it would be hydro-locked and would not crank over iamwiz82, if that;s what you are implying

it'll crank after something breaks when the pistons try to compress the water. I've seen it

Details, details.

The starter motor wouldn't be strong enough to break engine internals, but it could turn over if something broke when it first hydrolocked.

It would probably make some not so very nice sounds, though.

 

Notice that he did not state that the engine made any noise what so ever when it shut down, do you think I'm stupid iamwiz82 ?

No, but he didn't go into much detail either way

 

Well he didn't state "I drove through a deep puddle and my engine made this horrible noise and now it doesn't start" did he ?

A picture is worth 1000 words. He tried to crank it after the engine shut down due to ingested water.

 

engine shut down due to ingested water

Key words here.


Highly unlikely, that crank exited the crankcase because the engine was running when it ingested water unless of course he had a 50 hp starter

What we think happened was that the first cylinders were fine and fired without an issue, but they compressed the one with the water in it and it aided in his air intake.

aided in his air intake.

Please explain this phrase to me.

Hmmm...... Are you sure that's how the story went?

That'd have to be one hell of a powerful starter motor. :Q It takes a lot to break a connecting rod, if you imagine the forces they're put under while the engine is running....

Although, I think I understand your point. I suppose its possible that if say, one cylinder ingested water.. and when you tried to start it, if the other cylinder(s) fired, it could probably throw the rod.

But in that case it wouldn't really be the starter motor doing it, so..

When I hydrolocked, my engine shut down as well, but I never cranked it until I pulled all of the plugs and it started back up after some prayers, cussing, and wrenching.

The "aided in his air intake" was a joke, seeing as how he has lots of fresh air coming into his engine now.

 

iamwiz82, it requires a lot more force than one or two cylinders firing against a hydro-locked cylinder to break a crank and send it out the side of the block, momentum is required.

I can see a bent connecting rod from such an incident, but a shattered crank, no.

Notice the little bits and pieces of block in the pic ?

Think the starter did that ?, that was from momentum.

 

[BHeemsoth]

Thanks Roger for your infinite knowledge!

First off, I am sorry i was not more descriptive initially. The car ran a little rough all the way home, but i did make it. I knew that it was water under the cap, but i figured it would just burn itself off.

I was worried for a little while that my car was indeed hydrolocked, and i was sh!tting my pants worrying about how i was going to tell my dad i ruined my motor.

Thanks ATOT (especially Roger)

A preventative oil change is not a bad idea...

 

[Dark4ng3l]

Well if the car ran after you hit the puddle than I would say the engine is fine.

wouldn't you just blow the valves and/or the plugs out the top of the cylinders?

Negative, connecting rods and the crank are the first to go unless of course you own a late model Ford with their el stinko modular engine, these blow spark plugs out just from running.

I can attest to that... the spark plugs on the modular ford engine that is... hell I probably have a dead one now...
