I have been searching and trying to find some good information on determining if a pair of mine are still good. I know Rich had a little write up that used to be in the for sale section but i cannot seem to find that anymore.

So if you have good site or some informative information let me know or point me in the right direction. From what i have found it is basically people telling everyone to have a rotary shop check them out.

I am asking because i just installed my new streetport and a used set of twins running non seq. I run the car and it sounds good. I run it again the next day and it is running on one rotor. I pull the plugs and see that there is definitely a lot of oil in the rotor housing possibly causing one rotor to not fire. I look by the stock twins and can see a good puddle of oil underneath them. I change the plugs and disconnect the intercooler piping and put a filter on the greddy elbow. start it up and bam it is running on two rotors.

The next day i pull the twins and cant see any oil just a lot of burned oil. The exhaust absolutely smells of oil. i just put my old pair back in and and waiting to see if the car runs better.

Anyone else know of another reason as to why there might be a lot of oil in the Tb/UIM or causing it to run on one rotor? besides blown twins

These are the spark plugs after a mile of driving the car.

Rear rotor housing are on the Left Front rotor housing is on the Right

 

This is in reference to the stock twins.

 

im kind of suprised no one has any input.

 

have you checked to make sure there is spark coming from the wire?

did you rebuild it?
oil can come from bad oil seals?

do you premix

 

^ twisted......omfgwtfbbq! I.....I pulled my plugs and.......and:

 

I'm also trying to figure this out so I pulled my entire intake system, intercooler and everything out, there was a puddle of oil underneath the twins.......so I think they might be blown (which is why they're not spooling)

 

yes there is spark coming from the coils.
I did not rebuild the engine. i had a specialist rebuild it.
No i do not premix.

More info.
PCV is eliminated and lower nipple on Filler neck is going to the primary nipple on the primary turbo intake.
Full non seq turbos.
PFC with commander and datalogit.
850 +1680cc injectors. Primary rail milled down. new insulators & new diffuser on primary.
Oil injector vac lines routed into the greddy elbow.

I'm a little confused as to what you are saying? Are you making fun of me or saying you have the same problem?

 

I have the same problem

your thread is a godsend......I was trying to figure out wtf is wrong with the car

I'll pull the twins out tmr
