Fumes in cabin. pros i need HELP

[icwalkinthugi]

damn just traded my 2000 civic wit GSR swap for this automatic 98 gs-t =[
welll

now it smells like fume everytime turbo spools
while im driving i cant even breathe ahhhhhhhhhhhhhhh
and its idles when its in drive and when i put it in to N or P rpm stays at 1500
transmissions lil bad but biggest problem is the smell while driving oo yea previous owner told me he did timing belt and some gasket that has to do wit the spark plugs
but the head gasket looks like its bad =[
and previous owner told me that some times it spits oil thru the dib stick area -_-
well please tell me what i have to change and how much you think its gonna cost

looking for goood mechanic guy in tristate area not tooo expensive =[ help me guys

Fist off, losing oil from the dipstick is common. When the rubber seal on the top of the dipstick gets old, it begins to harden, and no longer holds the dipstick in tight. First generation motors sometimes have a tendency to actually pop the dipstick out (I just experienced this last week during a mis-shift) and create quite a mess. The gasket by the spark plugs is part of the valve cover gasket set. The valve cover has a rubber gasket that goes all the way around the valve cover and there are 4 smaller circular gaskets that go around the sparkplug tubes.
Now, my question for you is; you said that the "head gaskets looks like it is bad," How do you know this? Did you take the head off? With out the head off, you can't actually see if the head gasket is bad. You will know if the head gasket is bad if you have oil in your coolant, or coolant in your oil, if you are burning white smoke from the tail pipe, and in some extreme cases, you could actually be spraying coolant out of the motor or find coolant pooling up in your cylinders. Also, if you do a compression test, you can sometimes determine if your head gasket is blown as well. I would suggest doing that and reporting back with the numbers.
Now, for the fumes. This is a really hard one to answer, as we do not know what it smells like. Does it smell like burning oil? exhaust? coolant? fuel? When turbo charges cars go into boost, the fuel pressure rises to accommodate in increased airflow. This could explain the fumes if you have an exhaust leak near the front of the car. It could also be that your turbo is blown. If the turbo is bad, it can burn a lot of oil which is can smell real bad. Check for shaft play. Up, down, back, and forth play should me minimal, (.035", or about 1 millimeter, which is about the thickness of 9 pieces of printer paper). There should be no in and out shaft play. If there is in and out shaft play, your turbo is pretty much done for.
As for the high idle, it could be a number of things, from vacuum leaks, to a bad ISC. My guess is that it's probably the ISC. They are a known culprit for idle surge and high idle with DSMs.
I hope this helps. And report back with your findings, it will help us further diagnose your problems.

It sounds like your PCV valve is leaking and I'm going to guess that there is a small breather filter on the passenger side of the valve cover instead of a vacuum hose running to the intake tube. Under boost the leaking PCV is allowing the crankcase to become pressurized. In turn those vapors are getting blown out of the breather filter (if you do in fact have one) and making their way into the cabin. The remaining pressure that is unable to vent through that filter is finding it's way past your dipstick.

I would start by replacing the PCV valve with an oem one. If you do have the breather filter remove it and run a vacuum hose (3/8" if I remember correctly) to the larger nipple on the intake tube. If it is already set up this way then just replacing the pcv valve may solve the issue.

I would also recommend doing a boost leak test. Make yourself a tester as shown in the Tech section. It is something that you will end up using many times over to keep your car running well.

Let us know what you find.

check compression.

thanx for the comment shawn
well i had a 95 gsx before and had BIG problems wit the head gasket
and it kinda feels same so i thought it could be the gasket
well there is lil bit of oil on tha where the block meets head and the fumes smells like exhaust fume thanx everyone oo yea how much is it to run tha compression test?

A compression test gauge costs ~ $20 - $50 and requires about 20 minutes of your time. The rest is free, and the good part is it is free after the initial purchase of the gauge.

1) Idle the car till it is warmed up and at operating temperatures.
2) Turn the car off.
3) Disconnect the crank angle sensor from the wiring harness.
4) Remove all the spark plugs
4a) This is a good opportunity to inspect the plugs and check that the gapping is correct.
5) Place a rag or cloth over the spark plug holes so dirt and debre doesn't get into the cylinders.
6) Install the compression tester gauge into cylinder 1
7) Push the gas pedal to the floor and crank the engine for two seconds.
8) Record the compression reading from the gauge and clear it
9) Move the compression tester to cylinder 2 and repeat steps 7-8 till all cylinders have been tested
9a) If the compression is off from another cylinder by more than 14 psi, poor a small amount of oil ... 1/2 cap full or so of oil into the suspect cylinder. Reinstall the compression tester and crank for a few seconds (If compression is raised as a result of this test then it is most likely a piston/ring issue and not a headgasket or valve issue).
10) Install spark plugs
11) Reattach Crank Angle Sensor.
12) Remove the negative terminal from the battery for 2 minutes, then reattach (to clear the ECU code thrown by having the Crank Angle Sensor disconnected).
13) Restart the car. (Note: if you did the oil in cylinder "wet" test, then you will belch alot of smoke for a minute or so... Also the car will run poorly till the ECU relearns due to it being reset... 15 minutes idle and 15 or so miles of highway constant speed cruising).

Remember to check the o2 also because the oil will cause it to fail.

 

[icwalkinthugi]

the comp test
anyother ideas?

Do the boost leak test like said above as well. They can make your car run rich as hell (possible source of fumes) and run like crap.

You got to also check for exhaust leaks. If you dump some seafoam into your throttle body intake line you will see smoke in the engine bay if there is a leak in your exhaust system.

I second the idea of checking for exhaust leaks. Turn the car on, block off the exhuast with a rag or something, and check underneath, especially under the cabin where you are smelling the fumes
