Tonight I was driving home and hit a large puddle of water in a parking lot. All of a sudden my car started knocking and chugging and my oil pressure died. I had the car towed home and there is oil leaking from it but I won't know where it's coming from until tomorrow when I jack it up in the day time.

Any ideas why this might have happened or what is leaking?

 

hydrolocked and sent a rod out the block?

 

Checked it out with a flashlight and there isn't any oil on the sides of the block and doesn't look like anything shot out of it.

 

yeah i too bet it hydrolocked and u cracked the block, do u have a ftra on the car?

 

No, I have FRA but I don't see how the water could get that high because the puddle didn't seem that ridiculously deep.

 

I would guess that you hit the pan and caused the rear main to leak.

 

That is how the guy I bought my car from explained what happened to my 98 Z. It had 2 broken rods and cracks in the block. They were very hard to see without a lift and a high power light. Good luck, but My gut feeling is you are in the market for an engine...

 

Good luck with it, if how ever you need an engine I'm here to help

 

I think you cracked the oil pan as well....

 

you guys think it might be possible that if the cold water hit a hot engine it could have cracked the block?

 

very very unlikely the cold water would instantly crack aluminum. and the from what it sounds like he was just starting off from work so i doubt the engine was that warm. but hell anything is possible lol. I still will lay 8 to 5 that its hydrolocked. If it is call the insurance company.

 

Cold water splashing from the road won't crack the engine.

Cold water entering the intake track and hydrolocking it will though

 

hmmm... just seems like i've heard of people cracking their block when they go wash their engine bay when the engine is hot... could be wrong, but could have sworn I've heard that before...

not saying this is what happened to the OP... but brings up the question if it's possible and if so, how possible...?

 

naw, the block wouldnt be cracked b/c of cold water....you drive in the rain right?

 

FMI,
How would the engine hydrolock by hitting a puddle? I mean I can see it of the water is up over the hood and all.

I mean does that much splash up into the air filter and get through the throttle body into the engine???

 

X2 on that.

 

x3

 

the water doesn't need to go over the hood.
It doesn't take much water to hydro an engine. 8oz or so in a cylinder would do it

 

I think what we are all asking though is how does the water get in there in the first place? The intake seems to be the only entry point....?

 

Once again X2!!
