Okay its definitel confirmed while leaving from my a gas station just befor e i could get on the road mymotor locked up and a bunch of steam came from under my hood.
then i noticed a coolant leak. I know that it didnt over heat because my coolant temp guage was at 190 degrees F andand the car had only been running for like a minute after start up from being parked for like 15 minutes. what are the possibilities of where the water is coming from. Im thinking a cracked exhuast port on the head.... or bad head gasket. either of which still makes me screwed because im hone on a 5 day vaction with 4 days till i have to drive back to NC with what i got no motor.????? i have sat sunday monday and it would have to be working by tuesday. Impossible with out tools. any way what could have cause this any clues.
i did have a crack in the number 1 runner of the exhuast manifold thats how i identified the leak internally on that cylinder could be on all. but i know it isnt coming from the TB because i eliminated coolant line for that. and I check the oil and no signs of water in the oil as its fresh i changed it just before the trip.

this absolutely sux. any help greatly appreciated
 
Along the front of your motor, turbo/exhaust side, there is an aluminum coolant tube about 2" in diameter. It runs from the water pump to the lower radiator hose. It runs against the engine, behind the turbo, under the exhaust manifold. It has a 1/2" diameter tube coming of the bottom side of it that runs down vertically about 3 or 4 inches and a hose attaches to it. Check that connection and if needed replace the clamp. It is located in between turbo and alternator, behind oil dipstick tube. Which is in close proximitty to the number 1 exhaust runner. If your lucky it could just be spraying out of there (easy fix).
 
:D yeah i pretty knowledgeable with the anatomy of 4g63t. I was well aware of the coolant tube from the water put to the low2er radiator hose. I definitley sait it wa s confirmed coming from inside the runner on my manifold. so its not somehting external its and internal failure. I think i might have preignited my motoror just detonated the thing horribly.

Unfortunately you're not as keen on the anatomy of a complete sentence with correct punctuation. :thumb: Anyway, w/o tools, you're pretty much screwed. You at least need to pull the manifold as Gary suggested, but I wouldn't consider turning that engine again w/o pulling the head. What makes you think you've been detonating? If you know it for a fact, why keep driving the car? If it was pre-igniting, you should be able to read it in the plugs as they are generally the most common cause of said condition. The porcelain will look melted down, splattered and fuzzy.
 
I speak in a few different languages so as fas as the why I talk and type I try my best.
Japanese,english, korean, french.

anyway. i see no point of taking off the manifolds at all point less i know where the coolant came from because i have a oil cooled turbo so coolant isnt coming from that direction. it has to come from the head if it came out a crack in my exhaust manifold. And I removed the plugs a while ag o and they show signs of preignition. I never tried to continually start it. it was just a note that the instant the failure happened i tried to check if my crank would rotate and it wouldnt. its locked. But looks like im building a new motor hurray college life is great.
 
well if your not able to take the manifold off yet look towards what we suggested then stop wasting everyones time. taking the manifold off is as simmple as it gets to the common tuner. if your not willing to investigate your problem then just drive the car let it brake. were here to help you out when you ask for it.

1) Being multi-lingual certainly doesn't stop you or anyone from using the spell-check.
2) You asked for suggestions, yet seem to think you know it all already, so why bother?

and before that he wrote:.....
pull your manifold off and check for coolent coming from inside the block.
Why would I listen to you in the first place "take the manifold off to see if coolant was coming from inside the block"?????:confused: you already seem ignorant in reference to IC engines.. the manifold is attached to head why would I do that.... I can tell you dont read posts in full too. ### you still think the motor rotates The car doesn't run and it preignited!!!!:confused: how did you miss that. Please don't offer advice if you don't read the full thread before you do :notgood: . That should tell you the car isn't going anywhere. and Also I didn't have tools to take off the manifold and if coolant is coming from a crack in the manifold thereis only one place the coolant could come from the head. Since I know I didnt over heat and my temp guage said 190 degrees F I also know I didn't blow my head gasket. so I checked my plugs to confirm that. and came up with preignition based onth spark plug appearance. so dont assume im not willing to investigate my problem just because I have alittle more common sense and think logically about things.



Yeah a common tuner can take off a manifold but does a common tuner have enough sense to realize coolant came out your exhuast runner after your motor suddenly stopped and seized and think "wonder what my cylinders were doing?" and read his plugs looking for signs of coolant entering the the cylinders for signs of a headgasket failure then identify indicators of preignition and call it a day?.....And even a common tuner knows the the manifolds bolt to the head ROFL

Enough of that mess.

once again I'm on here for verification see if there was some thing I was missing.
Like for instance some one who had the same symptoms etc or any one who heard of it happen to a friend.

the multilingual thing was more of like a" haha I would loose my head if it weren't attached" kinda humor. but still sorry about the grammar/punc you should be able to tell that from how I type now

I'm more interested in the subject at hand. apreciate every one who helped.

Yeah I got back to my facility and took a scope light to look at my pistons and there is a whole in in my number 2 piston so definitley preignited from what the plugs show and the cylinders look like. basically salvage what I can and move the hell on.
Anyways thanks tothose that did help im greatful you offered good solutions even if I was already going the same direction.
 
well i said block but i knew what i was trying to say. so you be buy-leingwal? haha and ill throw out all your words and sentances which dont make sence.
 
LOL yeah thats what I do its hard to switch between japanese syllables and english consonants and vowels it makes you talk like a retard and also type like one at times.

Like I said im not mad at anyone and aprecciate your valid suggestions
I just dont think it really matters to nit pic grammar and punctuation.

I mean you read "dont" and "don't" the same way right?

but enough of the :beatentodeath:
 
:D ohh kay well the hole in the number 2 cylinder was cause by a valve breaking off and falling it at 2500 rpms. it wasnt preignition at all . when I disassembled the motor to see what it could salvage. what I saw was crazy. when I first took off the exhuast manifold with the engine on a stand I noticed all 8 of my exhuast valves were gone and one was driven thru and still is stuck in the head on cylinder number 4 though. A hole from what was left of the valve stem on the valve that dropped into the cylinder was rammed thru the head on port 1 of the exhuast side of the head( thats where the water came from)
so when I took off the valve cover the upper parts of the stems were still in the retainers and seat locks still in place??????:confused: when I took what remained of those off there was no... none ... no signs of the valves bending at all along the stem. they just looked clean cut all 8. and the remainder of those valves basically shartered in the cylinders and exited via the exhuast ports. motor couldnt turn because fo the one valve that was rammed thru the head didnt make the clearance. .......

but the hey look on the bright side my cylinder walls are fine ROFL

and my intake valves are untouched too.

But thats what happened fromt the way I see it. all 8 of my exhuast valves broke at the same time. and sheared off at the same length almost.

Crazy stuff.

thanks for all the help just figured id let yall know its not preignition. what a relief for me:thumb:
