wow your good i didn't think of that but now i remember that yes they do sometimes use oil lines just like turbos

i also posted a link to this thread on another forum http://www.network54.com/Forum/11941...28blown+351%29

"Could be..... December 8 2008, 8:07 PM


-a cracked cylinder wall that is weeping coolant once the bores get hot.
-a cracked intake runner in a head, again weeping coolant.
-a crack across two or more bores (deck surface) or between a couple of head bolt holes and/or coolant holes.
-sometimes a blown gasket torches metal off of the block deck or face of the head (or both) and unless the head or block is surfaced, leaks can occur even with new head gaskets.

His best bet is to pressurize the cooling system, pull all the plugs and see if he can detect water entering a cylinder. Only needs about 10 lbs of radiator pressure...may need to jury rig up a "T" in the heater core lines and adapt an air fitting to allow the system to be pressurized. Patience may be needed here to find a small fault somewhere in a cylinder or two.. "

 

While some of this is possable it is highly unlikely.

I have magnafluxed more engines then I can even guess and have never seen a crack in an intake runner or in an undamadged cylinder wall. I have seen cracks from cylinder to head bolt hole or coolant passages on the deck surface, but that is vary rare and even more so on a modern Ford block.

A leak from coolant to cylinder will allow coolant into the cylinder when the system is pressureized when the engine is off. When the engine is running coolant in the cylinder is only a minor symptom. What you notice first is the engine overheating, the massive heat and pressure of combustion leaks into the coolant flash boiling the coolant out of the engine, overheating and over pressurizing the cooling system. And yes this is true for a head gasket as well.

I have NEVER seen a blown head gasket "torch" metal off the deck and don't beleive it is even possable.

Yes pressurizing the coolant system is a good diagnostic tool and one the OP should try there is a tool available that will do a much better job. a coolant system pressure tester is a pump that camps on like a raidiator cap and has a pressure gauge, just screw it on and pump a couple times up to the pressure # on the cap and watch the gauge if there are no leaks the gauge will stay steady, if there are it will drop and you can then look for the leak.

Edit, I do beleive the OP did have a blown head gasket. It was apparently an obvious blow, and I can think of no other likely option for water in #6. if it was an end cylider maybe but 6. The only other remote poassabilty is a coolant leak from the upper intake that somehow when the engine was off only ran down into 6, just a thought.

I read the other thread and bob also mentioned hydrolocking the motor. This to is vary unlikely it would require enough engine damage to occur that enough water to fill the compression volume could get into the cylinder on one intake stroke. If this did happen a blown head gasket would be your last concern total failure would be vary obvious.

If there is still water making it into the cylinder and it is not overheating it is almost certain it is coming from the intake.

Keep in mind and this is vary important, A little steam in the exhaust is a good thing and is not a problem. It is the natural byproduct of cumbustion and the catalitic converter. HC (fuel) combusts with O2 (Oxygen) to form H2O (water) and CO2 (carbon dioxide).

It's the blue that is a problem there is no good engine function that causes blue exhaust.

 

yeah i dont know whats going on bc i timed my truck with the blower off. but cant leave the belt off bc the sensor in the air filter is reading a a **** load of air going into the motor, where the air intake sensor is reading nothing. so i either have to take the belt off.... to run the engine or leave the blower hose connected. i have, "i guess you would call it" stage 1 supercharger, its not directly over the intakemanifold, but seperate from the engine. but when u talk about their bieng compression i dont exactly no what you mean.??

 

do you mean water in the supercharger itself

 

What brand and model of supercharger?

Compression is the squish, in the suck-squish-bang-blow of a 4 stroke engine. Intake-Compression-Combustion-Exhaust

No unless you are driving through a stream I see no way to get water into the supercharger.

Do you have an intercooler, and if so is it water or air?
