oil smells like gas

[dan2288]

I just changed my oil today and noticed that it really smelled like raw gas. I have never smelled it like that. And this oil is really new, just a week of use. I had it in to flush the engine after a head gasket failure. I dont know what could be wrong. Nothing has changed, and it runs the same. Any ideas?

It might be sign of worn rings. Do a commpression check. Does your car smoke?

I have the same problems. ^ dont give bad advice. There could be a number of problems. The thread goes of topic but in the beginning you get the point.

Do you know if your running rich? I havnt found the culpret for my problem yet. But i do know im running super rich
Hope this helps,
Taran

The only place oil and gas come close to each other is in the cylinders. I agree, it may be that you are just running super rich and you are washing the cylinder walls of oil and the excess gas is getting past your pistons and rings. How many miles on the engine? If high mileage, you may have worn rings.

 

[dan2288]

Not too much miles on the rebuild...about 5000. Never had this problem before this. My fuel pressure is at 43 psi on my afpr. I am getting pretty bad gas mileage. Not sure what to do. Im gonna hook up a scan tool tomm to make sure my coolant temp sensor is working. How can I check the o2 sensor?

 

[josh38127]

If you can I suggest a Leakdown test.

 

[My1GLaser]

Have you checked you PCV system? It needs to be functioning well to get the contaminated blowby out of there quickly or it will dirty your oil.

How much boost are you running? How old is the PCV valve? Do you have a check valve of some sort in line b/w the IM & PCV to keep boost pressure from blowing past the PCV valve?

I had the same issue i was just running way rich. What tuning equipment are you using ? If u need a hand in figuring out ## issue i would be willing to help im from the reading area. U can pm me and ill send my cell number

 

[Grimis]

same problem found out #3 injector was staying open after the car was off and leaking.

 

[dan2288]

Im pretty sure the pcv valve is working fine. I do have a check valve in line. My fuel pressure always drops to 0 when I shut the car off so I dont think a leaking injector would let too much fuel past it without pressure. And I just have a keydiver chip for my 880 injectors. I had it for over a year without any problems. I have a walbro 255 pump but my afpr is set correctly.

 

[dsm-onster]

If it is bleeding down to zero fast enough, it could vary well be a sticky injector.

 

[dan2288]

how would I be able to test and see if its the injector?

 

[JusMX141]

I suggest you address this problem as soon as possible or you'll risk washing the bearings and cylinder walls, ruining your brand new engine.

 

[dan2288]

yea, Im trying to . I hooked up my dads snap on scan tool and monitored some things. Looks like the coolant temp sensor is working right and the o2 voltages were always changing. Is that right?

 

[BogusSVO]

yes the o2 should switch back and forth....

cycle your key (not to start just run) let the fuel system prime up some... then pull the vac/boost line and sniff for gas... you may have blown out the diaphram in the FPR..

that hose has to be dry....

also a quick way to see if you have an injector leaking.. pull the fuel rail, zip tie the injectors to the rail and then cycle the key to prime the fuel system.. if one (or more spray) thats the bad injectors.... make sure you unplug the wire harness from the injectors too

*NOTE* this is NOT the best or safe way to do this!!!!!

 

[asb2106]

fuel pump doesnt turn on my 2g's until cranking starts / sometimes later

 

[dan2288]

yea, i dont get pressure until I start cranking. My car always had trouble starting after it sat for a couple hours. It would just want to die and I could smell raw gas. But my oil would akways be good. This just started a week ago.

 

[BogusSVO]

jump the fuel pump relay...

 

[dan2288]

Will do. Just another thought. A couple of the plugs that go on the injectors cracked. I was still able to get the plugs on but they dont clip in anymore. If one happened to get loose, would the injector be stuck open and shoot fuel in or would it not work and have no fuel go through it?

 

[BogusSVO]

it should defalt close.....

hit the pick and pull and get you some new pig tails and solder them in.... you have a typical bosch injector... so it dosnt have to be from a Mitsu.... Ford.. Chevy... whatever...just get the style for the injector

 

[dan2288]

yea, I will have to get new connectors. As long as it doesnt stat open then that cant cause my problem. I will be looking at some more things tomm then. Thanks so far!
