Broken again BIG TIME. Need my brothas help here.

[Hurleyatticus4]

So friday I swapped the ported small 16g for my 14b. I went to streets (huge meeting spot) [content removed]

Well, the next day I drained my coolant and put in the new stuff. And I was driving around and I noticed that when I would open the car up and get around 6500 rpms, that the car would like, cut off and jolt forward (knock of some sort?). I figured it was because I'm still using my stock 450cc injectors and I'm running really lean.

So I went back to the race area that night and [content removed] I launched from about 5000rpms. Next thing I know before I shift into second there is a big clunk/clink sound and the car feels like something is dragging under it and I couldnt put it into gear. I immediately though "Great, blew the tranny again 2 weeks after I redid it." But when I pulled over to the side of the road, nothing was dragging under the car, and all my coolant was leaking. Smoke was billowing from the hood obviously. But I really don't know what is wrong with the car.

We pushed it into a lot nearby, and it was making a clicking sound while we pushed it. I'm pretty sure all of the coolant is out of the car so I am afraid to start it right now. While it's sitting I can go through the shift patterns and everything seems fine. So what could be the problem?

My friend is coming over to look at it after school, but I thought I would ask some of you here who are more experienced.

Water pump? Old faulty hose maybe? Why does it feel like something is dragging under the car? Did I blow something?

Please let me know if you have any words of wisdom. Thanks guys.

street racing is looked down on here majorly...

Your from schaumburg, huh?? If its in a parking lot, I could drive down and give you a hand if you'd like , LMK, Im available all day long. I hate to see a broken Talon in my area. It could be a couple of things. It wouldnt go into gear when the car was on???? Did the motor die when you heard the clunk noise?? Oh, and that cut off and jolt was from you hitting fuel cut off, you maxed out your stock injectors, what psi boost are you running??

 

[coving21]

I't could be a bunch of things, once you figure it out upgrade to 550cc or bigger and a new fuel pump. Also even if all the coolant leaked out, you can still start the car just don't run it for more then 30 seconds or so and watch you temp! maybe 15sec to be safe.

No, dont let it reach operating temperature.

To respond to a couple of the answers here, I do have 560cc EvoVIII injectors, they just aren't in yet because I haven't yet recieved my SAFC-II. As soon as that gets here I'll be putting in the injectors.

robs90tsi, we pushed the car from the bank parking lot, down higgins and onto my street. Eventually to my house. It was FREEZING haha. So right now it's sitting in my garage. My friend Nick is coming over today to check everything out, and then I'll let you know if you could be of any help. Thanks for the offer.

So I need the bigger injectors in and I need to find out where the leak is coming from?

Thanks guys

Did you check for boost leaks? They cause fuel cut also.

I think you answered your own question. If you gave us more information about how many pounds you were running we might be able to help you. Most likely you killed the motor.

 

[coving21]

No, dont let it reach operating temperature, you can let it run, just once it reaches operating temperature, the thermostat opens and circulates the coolant, in your case, you dont have any, so if you want to let it run, just shut it off either as soon as it hits operating temperature, or just before.

 

[boostedinaz]

Do not start the car and let it run. There is no coolant so it will heat up much faster and you will not know what the actual temp is becasue there is no coolant for the sensor to read. Have it towed or risk damage. Some will say they have done this and that, but they will not send you money if it does not work at for YOU on YOUR personal case.

 

[robs90tsi]

^^^^ Ah, see completley forgot that your temp gauge is for your coolant, since theres no coolant, you cant get a good if any reading, forgot, thanks for setting me straight on that one.

IM so glad you saved me from typing that.

boostedinaz, I was boosting roughly 18-20psi.

To repeat a few things:

*The only fluid that leaked was coolant.
*It felt like something was dragging under the car.
*I only tried for a few seconds, but it would not go into gear right after the whole shebang after the launch.
*While the car is sitting, and off, I can go through the shift patters smoothly
*The car is already at my house, we pushed it here that same night
*The car was making a weird clicking noise while we pushed it, and I believe it only does it now when the wheels are all the way left or right

NO, the car did NOT die right after the sound during the launch, I was able to let it roll to the side of the road and I shut it off once I saw the smoke coming out from under the hood.

Hopefully this answers some things.

That is way to much for stock injectors. If the motor isn't dead be glad. Let us know what you find.

If it only makes noise when the wheels are and full lock it could be a CV joint check those out.

Dude, why do you guys get DSMs a think you can just go around and run that kind of boost on a stock motor. I replaced the motor in a 2G TWICE in a six month period because the kid couldn't learn his lesson. First time I got his shortblock under warranty somehow. He destroyed #2&#3 running 20psi out of a EVO 16G on a stock motor. New short block and kid some back with a hole in the block the size of my fist on the front side. I shine a light in and realize I can see the starter. Pull the pan and the girdle is in three pieces. #4 was there intact but the piston top was heavily damaged. #3 was there but seperated from metal nub hanging from the crank. #1 & #2 were completlely gone out the block. 16G was also destroyed. I was like dude. WTF were you doing? 25lbs of boost. but now he had a Buschur 3" and an SAFC. People wonder why Mitsu is crazy with the waranty on the EVO.

Moral? Cross your fingers and hope you didn't just toast anything major! DON'T RUN MODS/BOOST THE ENGINE CAN'T SUPPORT! If you ran my FC the way you run you DSM, it would have blown up from you just turning the key.

Pull the lower oil pan make sure it's all right. Get some coolant in it and see how it runs. DON'T run without coolant unless you really want to warp the head. Coolant Temp Sensors aren't made to read steam temps. Check the Xter case as well.

If your car jerks when you are at high rpm with an upgraded turbo running more then stock boost your computer detects higher boost reading and what it will do is shut off the fuel and the spark to the motor causing to jerk or jult. hopefully this will help with your question

 

[olmytsi]

Do you at least have a fuel pump?
