So I can't seem to find much information on diagnosing bad stock twins. I have lots of oil coming out the exhaust, blue smoke everywhere. It is also running quite rough. I have experienced a blown turbo in my speed6 before and it also blew tons of smoke and ran terrible. Which I'm guessing is from all the oil on the 02 sensor. The motor is freashly rebuild with new oil control rings so I almost feel like it's the turbo. It has also been fouling plugs, which may be from the bad 02 readings and it running super rich.

Any ideas?

 

who rebuilt the motor?

 

I did

 

was it your first rebuild? Did you reuse a lot of the components?

 

It's my second, I reused some parts but they were in good condition.

 

Check and see if your turbos are spitting oil, also did you clearance and clean everything when you did your rebuild? Did you check the OMP injector valves?

 

you mentioned fouled plugs, were they oil soaked? if so, sorry but you gotta rip the engine back out again.

a faulty turbo will leave oil everywhere past the turbine wheels, a faulty engine will leave the plugs soaking in oil.

 

I am running no omp and 1:100. The plugs had a little carbon on them and fuel so I really don't think it's the motor. What would cause oil like that internally?

I will try to get the down pipe off tonight to see if there is oil in there.

 

im interested on the outcome of this post.
Having similar issues. just park the car and haven't touched in about 6 months since then.
i have a spare use twins that i will replace some time next month. if doesn't work, well.. REBUILT will be the plan B.

sorry yourmom23 to hack into, but this is a good post.

 

how old are the turbos?

 

I just hope I can figure it out, these cars can be really frustrating.

 

Honestly don't know how old they are, the previous owner had a jdm motor put in at some point.

 

I pulled the plugs the trailings were dry I'm attaching a pic of the leading.

Took a short video of the car running, if you try to rev it above 3k it just backfires.
I have no clue what's going on I have double checked all my connections vacuum lines, and tried a different ecu. Nothing seems to help.

 

map sensor issue

 

**** have you seen how much they want for the?!? 500 bucks wtf

 

i didn't say it was the MAP sensor, they rarely if ever fail that i've seen.

check the lines, check that the filter isn't plugged somehow, check the routing for kinks or whatever. and last but not least check under your left front fender for the tire rubbing through the harness.

 

Thanks for the reply, I checked the map sensor lines and filter. Nothing seems out of place, checked under fender and nothing there. I also set my tps, you do that with the ignition in the on position with the car not running correct?
