In the morning started it up, and it started fine. Drove to the store without boosting at all since I have a boost problem. Came home parked it, and 30 minutes later went to start it again and it started to shake violently. Idle was dropping real low and wanted to die. Then finally it just died. Started it up again and it started fine, but just seconds later car shake and dies again. I look under the car and see a puddle of oil and the car smell like gas. No smoke at all. I have 127,000 miles and believe it's gone. Any suggestions. I check the map senor and it's good. I could see some kind of liquid dripping all along to Y pipe. I thinks it's gas but could be oil. Damn now I'm stuck with bucket for a daily driver and a dead seven. Time for the rebuild.

sounds dead to me

R Xplicit

have you had an oil leak?
and what kind of boost problems were you having.....


otherwise, it looks dreary to one extent or another

check fuel pressure and then compression. Its kinda funny that it would just go like that but weirder things have happened.

Good luck

Yeah I've been having oil leaks, didn't think it was that bad. My car seems to burn off oil about 1/2 quart every 300 miles. My boost problem is that I get no boost before 4500 rpms and boost after. So basically I drive with no boost at all, only somtimes when I drive hard. Okay I just went to start it with the car completely cold and it started fine and then it held idle at 1200 rpms and was shaking bad. How do I check fuel pressure?? I know how to check compression but not fuel pressure.

you know she's FUBAR big time when she's leaking oil real bad and gas is dripping. it might be a turbo that blew up and pissin oil ever were

skunks

you just pull off the fuel line in the engine bay, the fowarm most one, then hook a gauge up to it. check on iluvmyrx7.com with the manual on how to do it, there are pics.

get the leaks done man before you asssume the worst. Find out what's the problem is. If gas is leaking then it's not reaching your engine, that may cause it to die. Good Luck!

126k eh, I say time for you to get a new motor ne way

It sounds to me like your primary turbo might be bad and puking oil into your engine. It may have finally pushed enough through to start fouling out your plugs.

reza

like paw said, maybe your turbo is leaking oil.
The oils may pour into turbo, blocking all possible air passages in turbo.
Thus your engine could not get enough air.

Try this, but don't drive it.
Take out the intercooler top pipe, this is the one leading to throtle body. Start the engine, see if its better.

Thanks everyone for there help. I spent all day looking for a new car. I already have a beater/daily driver but my girlfriend needs a car to. I will check all these things in the morning. Thanks for all the help. I notice that my secondary turbo has oil all around the outter part of it. I also notice that looking for the bottom up. Their is a stream of oil coming from the under the top of the UIM and is leaking down right in to the front rotor leading plug. I can't really see if in fact it is coming from the plugs but I will check tomorrow. Thanks for all your help and I will keep you updated.

I notice also that the puddle of oil on the ground was directly under the turbos. Thanks

Well today I started the car again and the had to jump it. In the process of jumping it, it started fine, and did the accelarated warmup, then it started shaking. To my surprize I saw liquid shooting out from under the back of the UIM. It was definitally gas because I can smell it. I'm now in the process of taking everything apart, and as I was doing this I notice several oil leaks coming from various gaskets. It seemed like all the gaskets were leaking. Now where can that gas leak be at?? I assumed the fuel hose/fuel rail/leaky injectors/fuel palsation dampner. I have never came accross this problem, and don't know where to start. Where is the fuel hose?? Where is the fuel rail?? and where is the fuel palsation dampner?? Please help??

Once you get off the UIM, the location of the leak should be obvious. If it is not, you can run the fuel pump by jumping these two leads in the diagnostic box to find the leak(can't remember which ones... fuel pump and ground?)

The fuel lines run up along the driver's side firewall and under the UIM. There are two lines. You probably either have a leaking line or FPD.

Which gaskets are leaking oil? If you are leaking oil from your intake gaskets, your turbos are leaking way too much oil.

Once you get the UIM off, let us know what you find. I think it will be obvious what is wrong.

take some pics so its easier to understand where the leaks are comming from. becareful not to strip the injector holder plate things (the plates that cover the injectors), these are phillip head screws that seem to strip very easily (i stripped 2 of mines, the primaries and it sucked eggs)!!!

blackscorpio

its times like this when a fuel preassure gauge comes in real handy for the diagnosis. Sounds like you have a fuel leak, should be prettu easy to spot, just follow the ful lines from the firewall till you see where the gas is coming from.

Well today I took the UIM off and now I'm trying to get the soloniod rack off too. I've gotten the black thing that hooks up to the spark plug wires off,next to the rats nest off. I'm trying to take of the rats nest, I've gotten to right side which is the closest to the firwall side off but can't get the side closest to the altenator off. I'm gonna take the altenator off and try from there. I did'nt take the 6 little screws out, but instead went the route of taking the entire assembly off. What is holding the left side of the rack in? I can't see because of the altenator. I've decided to replace every single hose, from coolent hose/fuel hose/turbo vaccum hoses.

Liemoanh

How many bolts hold the altenator in??
How many bolts hold the entire soloniod rack in, excluding the 6 little phillip screws??

Thanks guys I will try all your advice, but it's gonna take awhile. I work from 7AM-5PM and only have 1 1/2 hours of sunlight to work on the car. I plan on letting the car sit for 1-2 months at most. Any suggestions on what to do when letting it sit? I've taken out the battery, but thats about it. Any suggestions?
My oil is leaking from the gasket under the UIM, it's not the gasket that connects to the LIM, but the gasket directly in the middle/under the UIM. Also from the oil filler gasket and I have alittle oil in the hoses from the Y pipe all the way to the UIM. I also notice two broken soloniod nipples on the bottom of the rack. It's the third to the last one and last one closest to the firewall. This explain boost problems. I will keep you posted on my situation, but keep the suggestions coming?? Thanks for the help.

Liemoanh,

FYI, theres going to be a San Diego meet on Giovanni's on Clairemont. I probably won't go, but just thought it might help you in your situation to talk to others in person. Even see if some can help you out. Good luck dude!
