Really Weird

[lilrob2069]

Ok so i have looked for 3 hours trying to find an idea of why I am running rich. I have eliminated the boost solenoid, put in a boost gauge, just did the oil change and put on a new turbo back exhaust. Since all this it is smoking and i can smell gas any help please.

 

[KEEBS]

If you have a BOV venting out and no MAFT between the BOV and Intake, it will run rich

His mods doesnt show an atmosphere BOV...

No im not venting to atmosphere. My car was down since saturday, and i put on my 3 inch turbo back exhaust, and did an oil change... 2 weeks ago i removed the bCS and put in a boost gauge, everything was fine until today once i finished on the inner tie rods. and noticed that while idling it was smoking so i smelled it and it smelled like gas pretty bad, after i drove it for 20 minutes, it went away, i shut the car off and restarted it right away and it was smoking again. Also now, when it warms up i noticed that while trying to pull in 3rd, thats it sounds like my exhaust is blowing out. still seems to boost fine, 9 psi but other than that i mean it runs pretty good. Just cannot figure out why it smokes like it does. I have been having trouble with my temp gauge staying at the first line. I bought a new thermostat and temp gauge sensor just haven't had time to get that done.

Ok guys so i kind of been watching closely to see what could possibly be wrong. When i first start my car it doesn't smoke at all. once it get warmed up it starts smoking and smelling like it's running rich. I believe it is my thermostat causing this cause my gauge doesn't go past a certain point. so i believe the car isn't getting up to operating temperature and the ecu is thinking it is still cold. making it dump more gas. does this sound like it could be it. I do know that after driving the car for 10 minutes it won't smoke at idle until it idles for more than 5 minutes. and my gas mileage has been pretty low.

It could be the coolant temperature sensor for the ECU. If that has gone bad the ECU will think the car is cold, even if it has warmed up.

That was a possibility But everythe fan kicks on like it's suppose to. So im not sure.

I think im gonna post a video on here so everyone can see whats exactly goin on.

 

[lilrob2069]

Alright so Here's the deal still haven't figured out whats goin on. My buddy rebuilt a turbo for me to swap out. Im not running rich, What is really going on is the car doesn't smoke when started up. After 10- 15 minutes it starts smoking. It's oil for sure, i checked my oil level and it's was low so i added some more oil to it. But it gets kind of bad on warm days. I smells like oil and im loosing oil, i think it's my turbo seals. has anyone had this problem before. because i would don't want to change the turbo and that not be the exact problem.

I see everyone is eager to help anyway have you done a compression check? Do both dry and wet and let us know what you come up with.

How many miles are on the motor? Does it smoke heavy under boost? The valve seals like to dry up and crack, that was why my car smoked. Also try replacing your PCV or cleaning it.

New pcv, 78000 original miles on motor. I only smokes when idling, once i drive it for like 5 minutes it will go away, and then let it idle for 10 minutes and it will do it again.

It has probably been doing this for a while. You had a CAT before you put on the new exhaust, correct? The CAT will clean up quite a bit of burning oil in the exhaust, now your new exhaust is free flowing, allowing the burned oil to show itself.

Definitely do the leak down test and replace the PCV

Ok guys one of my buddy's that has a dsm is running 15w40 and said try that, if the smoking stops then it's possible the 10w30 is thinning out and getting passed the rings. He said as long as i let the car warmup before i drive it then i will be fine to run, but don't just jump in and go. Is this possible. to run it without any problems

 

[Bluefire16]

You have not even told us what color smoke it is..... Is it black?

No it's blue for sure, I just had it over to my buds house and we were checking it out, the car only smokes when it's not boosting. Some of the guys there are running 15w40 which is actually a turbo diesel oil, I work and at a ford dealership. ANd i was gonna try it to see if it works.

 

[Bluefire16]

Have you checked the turbo? Check for shaft play...

What oil are you running now? 10w30? I have ran that for years, and so do many people. I also live in Michigan and my 10w30 does just fine for me.

Its possible your thrust bearings or turbo seals are going bad.....

Also, do a compression test, if your seals are bad in the head, you will find out with this test.

Checked the turbo, lil amount of shaft play both ways, no oil pool up. But like most of the guys said that if it was the turbo it would smoke during boosting. It only smoke when idling. Which is weird. haven't done a comp test yet

To clarify, did you remove the BCS and install a boost controller, or just a boost gauge? The only way you can eliminate the BCS is if you put in a MBC, in which case you need a boost gauge in order to correctly dial in your desired boost pressure. Even then, you still need to leave it plugged in to keep from throwing a CEL.

 

[Bluefire16]

^^ False.

You can remove the BSC and run straight from the turbo to the wastegate.

But you are correct about throwing a cell if you disconnect it.

Yeah you're right. My mistake. He said he's boosting to 9 psi, so I guess thats probably what he did. Never mind!

 

[Pitt8807]

It sounds to me like theres a very good possiblity that the valve seals are leaking. This will cause your car to smoke at idle (especially cold idle). Do a compression test (both wet and dry) and there's a very good possibilty that you'll find one or more cylinders down.

 

[Bluefire16]

There are to many unanswered questions with this kids car. I think if he does a compression test he will get some bad results personally.

Yes unhooked the Vacuum liine from the BCS and tied it into one of the line on the Intake. Unplugged the BCS and No CEL. I've got a feeling it might have low compression but At 78000 Miles, and a Grandma drove the thing kind of makes me think Not. But you never know. I've been working so much this past few weeks that i haven't had time to do anything mechanical. Plus with christmas coming it's hard to drop some money. I started doin maintenance when i bought it but ran into problems and had to drop more into it to get it back on the road. All Front end parts. I did notice that At WOT the boost will go up to 14 15 psi. I haven't played with it much because of the smoking problems ask any questions and i will try to answer them. I have not done a comp test or leak down test yet. so exclude those questions. I have put a new pcv and removed the air can. thats about it and put a boost gauge in

 

[awdgocart]

do a compression test and try swapping the turbo out

 

[lilrob2069]

Well now i got bigger problems, Sounds like i have a collapsed lifter so now it's time to tear into some shit
