Hydrolocked Mirage Engine New!!! Pics

i know my way into cars. im not a certified tech or anything like that but i know enough. ive never pull a head by myself. Ive helped others do it and ive been thru the whole process but ive never done it myself. so i need a little reassurance and maybe some guidance of things to look for.

STORY

My best friend is on his way to his girlfriend house. She has been bitching the whole weekend because he had to stay at college for a ROTC training. It has been raining for a couple hours. raining like crazy. he is in a hurry, she is bitching, he hasnt slept since 3am when he got to the Training and he sees a big puddle. he runs it, his car has a open CAI coming from the side of the headlights. his car stalls and he calls his private mechanic :( me.

THE DIAGNOSIS

He didnt told me the car stalled while running a puddle until way later. so i went there, cleaned the ignitor cap, checked for current and tried to crank. i heard no crank. told him to push start his car, nothing. we bought a new ignitor cap as his was broken and a electrical spray(supposed to clean connections and [shizzle]) changed the cap and tried another push start. Nothing and it felt seized. i ask him again what had happened and he revealed that it died while running the puddle and i almost beat him into a pulp. Why the hell is he hiding that info from me? if the engine wasnt [fizzle]ed before after the push starts it certainly is. i tried to move the crank an it is stuck to hell.


SOLUTION

i have to fix it. :mad: and im not getting paid for the work either. (he is the kind of friend that when my ps3 was in service he came to my house without being asked and gave me his PS3 so i had anything to play with) He is helping me though. beside opening, looking for whatever is bend(there will be bends) and sending the head into the machine shop what do i have to look for?

we are also changing the timing belt(with its tensioner) and obviously the head gasket has to be changed. Is there anything i have to look for beside all the work involved?

when i got the corpse open ill post pics.

Its a 1995 Mitsubishi Mirage 1.5liters

thanks for the replys


EDIT forgot to say that i pulled the plugs and all of them had water in the gaps.


PICS









THERE IS MASSIVE damage to the lower parts of the piston. Also a very good looking S on the rod.

how about just getting a JY motor? seems the likely choice.

or sell the car with the description "freshly cleaned engine"

but seriously if it feels seized i would check the oil pan as well. If water got in there its pretty much throughout the crankcase. I've come close to a hydrolocked engine but luckily i was able to keep my truck from dying when our town flooded. I got close, probably around 200-300 rpms before i was able to slowly get it to come back up and then i floor'd the bizzle to get it going again. that was a scary day, i didn't think i would have a day where the water in my area would be level with the bottom of the door.

Sounds like it possibly has bent piston rods. Does it turn over freely with no spark plugs in the head?

nope not turning at all, the starter is not moving either sounds like its trying to move.

i cant move it with a wrench and a tube. i know its fucked pretty bad. i hope i can fix it in a day but im not positive.

Yeah, it sounds like that motor is toast. You would be best off finding a new motor from a wrecked car and swapping it in.

Just for fun, tear down the dead motor and post pictures of the carnage. I want to see some bent rods!

UPDATE:

We worked on the corpse today. it had a lot of water on the exhaust manifold. Pistons show a lot of water in there too. Apparently the head is good:confused: its turning well by itself(disconnected the timing chain and tried to move it, it was moving ok) but i suspect there could be something bent in there. The bottom end must look like spaguettis(sp). we didnt work much on it and we were stuck with the oil pan because theres a screw impossible to reach. we will hunt for more tools tomorrow and work on it on wednesday hopefully. unless the storm hit us then i will spend the day eating soup, playing video games and enjoying my wife:D

i think i should start looking for a motor:p well he has to start looking for a motor, my wife is starting to bitch about his car being too much time on the garage.

even though this has been hard work and theres a lot more involved it has been a HUGE experience for me, to do this by myself for the first time. :jump:

as soon as i have and inside view ill post the pics!!!

:( there was nothing nice to show maybe when i take the bent rod out. its not that bent either. i was hoping for more carnage.

what happened was that the piston went into a side and there was lots of metal chips in there. it was not a radical position either. just went like 5 degrees off its flat position. the head is perfect everything is moving right. there was lots of water though.

what really got fucked was my finger. i lost two huge chunks of my pinky finger while moving the head checking for anything stuck, the timing gear crush it pretty bad and it thought i lost it. thank God nothing broke.

still woulda been worth it to see pics.

We could have sent them to the spanish tuner, "water cooling the bearings, give you 40 more HP!"

Hope that pinky is okay. Crushed fingers suck :(

i have some doubts on timing this bitch
left only the link because i cant resize the pixzsx :p

http://i202.photobucket.com/albums/aa214/prjavelin/timingdiagram.jpg

im using that out of a manual i found online. thing is since the piston was stuck i couldnt mode the timing to their timing marks i had to take it apart and now im a bit confused on this.

i know i have to set the #1 piston to TDC of the compression stroke. i think that settings the pistons is not the hard part. setting the heads is that i find the hardest.

im confused on the gears as the cam gear will rotate once while the bottom one will rotate twice thru the cycle. pretty much the heads gear is fool proof. now how do i set the pistons?

this motor moves two pistons to TDC and two go to BDC. i think that setting it either way will not create trouble. if i rotate the small gear in first or second rotation will not create problems.

anyways, can anyone clear my doubts??
