2G Please help ASAP. motor messed up

[BlackRaptor]

Hey guys it's me again I've got a lot more info here and i'm hoping and praying someone has seen this problem before. I thought it was a head gasket but i don't think it is anymore. Here is a quick break down

Car as NO power what so ever. When you rev the motor it revs very slow the motor has a hard time revving up. almost like it's under a load. this is when it's in park It will rev all the way up just has a hard time.

I dropped the oil zero antifreeze in the oil. Oil was clean.
It is leaking antifreeze out the water pump but thats going to get fixed but wouldn't effect this problem

The car does not smoke at all.

It starts up normal and runs fine motor sounds smooth. it's when you give it gas.

One thing i'm fixing tomorrow is they had the BOV venting out into the air. which i know messes some things up. like when i rev it up lets say 1/2 gas and let off it kicks and the motor dies.

I took it for one drive around the block. it builds boost you can feel when it starts boosting but the motor has zero power it will rev all the way up while driving but the car willl not pull hard at all the motor is all revved up and it feels like it should be jerking forward but almost no exeloration.

I'm really confused because if it was a head gasket it wouldn't run that well would it? other then the slow rev.

Almost feels like if you had a bad clutch in a car and when it revs up and boosts it just slips and zero power is getting to the wheels. well enough to pull the car along but nothing more. it's an auto though and goes into D and R just fine. and if it was tranny whats up with that strange rev problem it not wanting to rev up quick.

The cams are loud the wine a little but i was told this motor is kinda loud.

Sorry this was so long i just tried to tell you everything i could think of.
I hope someone can help i am really confused.

Also me and a friend reset the timing just in case that was off that didn't help.

do you have a maft to vent your bov?.....if not recirculate it back and see if that fixes the problem....im pretty sure that could be it....since it drives normal is only at idle that its hard for it to rev correct..and also it dies...im pretty sure its your bov...if not maybe a boost leak?

 

[jepherz]

Yes, that could very well be it. If your BOV is open when in vacuum, you're screwing up the mixture at all times. Try fixing that and see what happens.

 

[EclipseTrbo420A]

Is the whine very loud? and how constant...all the time ? Does it get louder at certain points.

 

[BlackRaptor]

Wines as it revs up. louder as the motors RPM's go up.

It's loud enough where you can hear it from inside the car.

There is a very soft knocking sound too but I need to listen to the motor more before i can explain this one. Ahhh 4G63 motors haha.


do turbos wine if they have shaft play? gonig to look at the turbo tonight also checking very bolt changing every fluid tonight. going to go over it with a fine tooth comb.

I hope the turbo isn't shot i wanted to put my Hahn turbo on my 420A Eclpise but i want the GST boosting before that.

Thanks for the help guys.

Good thing i got this car dirt cheap.

 

[dnhieu]

does the sound sound like WHOOOOOP when you rev it up? you might be kissing that turbo good bye. that would be the sound of blades hitting the inlet of the turbo...

Yes your symptoms do point toward a turbo. Just check the play and report back. Up and down/ also In and out. Look for oil in the housings. Goodluck.

 

[Dream On]

Pull the intake and the lower intercooler pipes off the turbo. Check for shaftplay and oil in the lower pipe.

 

[BlackRaptor]

Thanks guys. Can turbos be rebuilt or for the money it's smarter to just upgrade?

Going to test shaft play tomorrow afternoon and i'll report back

thanks again i sure hope it's not shot.

would this cause the lack of power and the slow revs?

Upgrade...or grab someone elses used stock turbo if you dont actually want to make more power. I woule maybe grab a t-28 fr direct swap, but if you feeling lucky get a 16 or 20G haha Goodluck and SUPPORTING MODS!!!!!!!

 

[BlackRaptor]

I have a Hahn super 16G. But this was for a 420. Guessing this turbo is a huge pain to get onto this motor. or is it not that bad to bolt up? All i want to run is 15 psi with a FMIC and Exhuast and some other little goodies like underdrive pully.

is there a larger turbo out there if i am forced to upgrade thats perfect bolt on. it will bolt right into the down pipe the oem oil lines and everything? or they all will need a little modding to fit?

The T-28 is direct bolt on for the 2G's. Theres one in the classifides as I type this. Also you arent going to want an aftermarket underdrive pulley. The only way to replace your harmonic dampner is with a pulley that has dampening capabilities. If your stock one is fine then leave it, Trust me and if not do a search.

Back to the T-28 its equivelant is a B16G which would be a great street turbo for a moderatly cheap and safe set up of a 190 fuel pump, 550's and AFC/Logger combo even though DSMLink is perferd. Othe small stuff like exhaust and Ic piping will help as well. Goodluck.

 

[BlackRaptor]

Well I think it's shot it's got some shaft play and i hear metal clanking. guess i'll be looking for a T-28. thanks guys. be honest glad it's this and not the motor internals.

going to do some more looking now if i figure anything else out i'll let you know
thanks again.
hopefully someday i'll be boostin haha

[boosted spartan]

i believe i speak for everyone when i say put the hahn on the gst..because if you do it on the 420a it wont go past 7psi (thinking your 420a is stock)..so it wont have as much fun as if it was on the gst....remember supporting mods..fuel, tuning, etc.

good luck.

 

[Spoolin4Ever]

Didn't he say it also has a hard time revving even in park?

I didn't know a turbo going out would effect the engines ability to rev in park or neutral?

 

[BlackRaptor]

Well i'm about to cry at this point the motor is 100% shot.
Anyone have a 4G63 that's rebuilt or in good shape they wanna sell or trade for a 00 CR250 modded motorcross bike? Thats what i'm having to sell for motor

Anyways i guess i'll tell the story.
The turbo on there now has lots of shaft play but the fins don't seem to be touching and the blades aren't bent BUT the thing is leaking oil and the intercooler piping has oil in it in every low spot right up to the intake in the IC piping.

Okay well i'm sitting there running the motor listening to the turbo there's still that slight knocking which isn't very loud at all which i thought was the turbo, now i'm sure it wasn't.

I rev the car in park up to oh 1700 ish rpm's and i hear a thud and smelly smoke. I look under the car to see chunks of cast. I'm sick at this point waiting for my mechanic friend to get to my house, which by the way, my garage is a lake of oils and stuff used up all my floor dry. haha Good thing I own my house otherwise the land lord would be out for blood haha

Anyways, my friend sees the cast and says what i was thinking something was sent through the block so after 4 hours we have the motor on the floor, which was easier then the 420A BTW.

I look on the backside and the oil pump went through the block on the back side of the engine there's a big hole about the side of two thumbs.

So lucky me is now in the market for a turbo *unless i can get that hahn to work* and a whole new engine.

if anyone has any advice on where i can find a motor please let me know.
pretty depressed right now.

in my shop right now i have a GS and a GST without engines. GS is just waiting to get put back together. GST's motor went straight to hell haha

 

[LessIsMore]

I look on the backside and the oil pump went through the block on the back side of the engine theres a big hole about the side of two thumbs.

Do you mean the rear balance shaft gouged a hole in the block?

A few years back my rear balance shaft spun the bearing it rides on and was just wobbling around in its bore, making a horrible knocking sound. I can't imagine it could lead to a holed block.

You could always replace the oil pump, eliminate the balance shafts and patch the hole. Depends on the severity of the damage and the condition of the engine.

I'm sure you could find a motor in your area without too much of a hassle. Check all the local junkyards. I know around here 6-bolts are a dime a dozen. You may also want to drop a 6-bolt in if you have too much trouble finding a 2g 4G63.

And installing a Hahn 16g is easy. Pick yourself up either a 6cm or 7cm housing, swap out the monsterous 10cm housing and that bi*** will bolt right up to your stock manifold/O2 housing. You may need the necessary oil lines and j-pipe for a 2g install.

Good luck!

 

[BlackRaptor]

Thanks for teh Hahn turbo info.
I have one with almost no shaft play sitting in my shop guess it would be stupid not to just use that.

As far as the hole i'll take pics tonight and post in them so everyone can see the mess.

Is that the balance shaft that's hooked into the timing belt right next to the crank? That's the deal that went through the block.

 

[EclipseTrbo420A]

Ahh man that sucks to hear. Do you have a full turbo kit for your 420A or just the Hahn turbo? Anyway get those pics up.

 

[BlackRaptor]

For the 420A I've got turbo intercooler complete piping BOV manifold Hmmm i'm guessing i'm forgetting something but thats pretty much it.

Which i'm having to sell that stuff off now to help pay for this huge mess. I have a brand new log style manifold and other goodies i gotta say goodbye to now for the 420A boost project.

I need the money.

Oh well i just want this stupid GST running again. my luck soon as i get a new engine in i'll find out the tranny is sh*t. haha

I can't believe the motor went through the block.
I'll have pics up tonight around 9pm Minnesota time.

 

[BlackRaptor]

Sorry guys i'll have pics tomorrow i promise

I picked up a motor today
http://cgi.ebay.com/ebaymotors/ws/e...30010153816&rd=1&sspagename=STRK:MEWA:IT&rd=1

Lemme know what you guys think.
I sure hope it's a good motor i had to sell my dirt bike to pay for this. I am LOW on money dang DSM. Oh well i still love my car. haha

The Engine says complete so it should be a simple drop it. even has the turbo. onlt 45-65K miles too.

well for that kind of money that should be a sweet motor to get and just drop in. Make sure you get some oil running through there before you fire it up by cranking it over with the plugs removed, and honistly I would do alot of maintenance while its off the car like the t-belt KIT that includes all the new parts water pump, pulleys tensioner etc... Im sure other wil chime in with words of wisdom. haha Good buy for a qiuck turn around.

 

[BlackRaptor]

the motor has 30 K miles on it just talked to him
I have a timing Belt and water pump waiting in my shop.

Very jazzed, 7 days it will be here.
so 8 I"ll be boosting again. this gives me time to install my new FMIC new BOV Boost Gauges and other goodies.
My MBC gets here tomorrow.
And i have a fresh motor to bolt it down to.

And I'll have my Super 16G turbo down pipe all finished too.

Ahhh such a money pit

Hey, might I suggest some polyurethane motor mounts to go along with everything you recently bought. I just put mine in and it, along with DSMLink might be the greatest thing I have bought for my car. You can really feel the difference with the power going to ground rather than bucking back at your firewall haha. If I think of anything else Ill let you know.

Oh yea a head gasket and ARP studs would also be pretty east with the motor out.

Also that turbo might eat up the stock clutch rather fast so.....haha you know.
