Car Just Died. Annnnd Here We Go.....

Wtf... It would take a LOT of coolant to hydo-lock a running motor. That doesn't happen on a small drip or even a little stream. It would need to be gushing pretty good.

Lets do some math here....

Your engine is what... 4.6l?

4 stroke motor. Intake valve opens once every 2 rotations. So we divide that by two. 2.3L of total cylinder intake displacement per rotation.

Compression ratio is what... 8:1? 9:1? 10:1? For the sake of easy math lets call it 10:1

Lets go a step further: Assume that hydro-lock occurs when half of the cylinder space at the peak of compression is water. 20:1 compression. 1/20th cylinder displacement would be water.

Take 2.3L, divide by 20, we get 115ml injected into the engine over the course of a single rotation to clog it.

Now things get fun: Multiply that by 600rpm idle, we get 69 liters per minute to lock it. ~8.5 liters per minute, per cylinder. That's a LOT of coolant to leak in there to "lock it". It might run like a turd with even a fraction of that, but I reason that it would take a major leak to lock the motor. You'd notice it. Blown hose or something?

i was going to say it couldn't be the oil pump.. if the censor detects low oil pressure it automatically shuts the fuel pump to avoid engine damage.

did you check your coolant level? i doubt a leak would hydrolock the engine. it takes a good amount of water to cause that.. my 4.6 was leaking water through the intake and all it did was throw a code on that cylinder.. could be bad install on the KB or they fucked with something that last time it was there..

P.S.

no buy backs on your gear

This is my baby. I'd know if the coolant was low. AND I guess you missed the earlier posts about the intercooler and possible failure.

Thanks, long story short, the intercooler is not the issue.

What did the dash cam pick up of the guys doing the service?

[OrionStang]

Dash cam was inop on this one. I had to unplug it since I couldn't start the car, and it was acting as a parasitic draw.

Just got the car back, its running fine. There is a ticking noise from the bottom end that wasn't there before, though. Not gonna risk it, having it towed up to the performance shop next week.

what a fuckin mess man. At least it's running again and you don't have to redo the whole motor.

knock on wood brah knock on wood

[OrionStang]

Still gonna rebuild the motor. I need reliability. And power LOL.

Hittin up Pardeus?

[OrionStang]

Im open to options.... but pretty sure I'll be using L & R Engines out here, support the local economy.
