thanks for the pic, I wasn't sure if simply disconnecting the OMP electically would disable oil delivery...I will give it a try.



I may take you up on the fans just to trouble shoot whats up with my set up (when would be a good time to pick up?). I find it hard to believe both fan motors burnt out at the same time... I was able to verify it wasn't my sensor connection since grounding activated the fan relay...just no action at the fans..arrgh.



Thanks again,



Chris

Well if disconnecting it doesn't do it then nothing will short of removing it entirely. Did k2rd send you the block off for it? Anyway I got to run around today and BBQ at my folks tonight but I will set the fans on the front porch for you. Come by for them whenever you like.

Dave thanks again, I owe you big time!



Arrgh, I just looked at my OMP connection and it was only half-way in!!!! This damn thing could have been running during initial break in without any OMP at all and no premix!!!!!!!!!!!!! https://www.nopistons.com/forums/pub...DIR#>/ohmy.png https://www.nopistons.com/forums/pub...DIR#>/ohmy.png https://www.nopistons.com/forums/pub...DIR#>/ohmy.png



I wonder how long it takes to trash a motor without OMP running or am I just being way too paranoid?? Motor has maybe 30 mins total run time.

Chris

you have a power fc? the power fc doesnt care if the metering pump is plugged in or not, be nice if it told you.



it takes hours to kill the motor with no metering pump

Yea Chris, these rotaries are way stronger than you think.



Mike, he is using a purple box.

hmm it should have freaked out? any other codes?

I would suspect that with the connector off, the pump would simply

stay at the last position - it would still pump. It looks like the

electronic pump just uses a stepper to adjust the stroke, and a pot

to sense where the stroke currently is.

Again, thanks for the sanity check! I connected the OMP and saw no difference in the smoke. Guess I need to stop freaking out and take things one step at a time.



I am going to focus on the fans and getting the battery permanently mounted so I can take it out on the road. I will stop by to pick up the fans in a few mins Dave.



Thanks,



Chris

No codes set on the PFS but I see check engine light comes on after initial start up... need to figure out how to pull the codes so I can see what the prob is.

Years, really. There are some "rotary gurus" near my area who remove the OMP altogether, no premix. It just wears the engine out faster. All the unburned gasoline at the ends of the chamber does provide some lubricity, albeit not as good as oil will do.



Not recommended for running under boost or high RPM for extended periods of time!

Well took it down the road again, and the smoke was just way too much to take it any further... pulled it back in and realized I had quite a bit of smoke coming up into the engine bay from the turbo/exhaust manifold area as well.....looked underneath and there is quite a bit of oil dripping out of the exhaust sides of the turbos....I see it also dripping from the connection between the DP and Cat so alot of oil is being pumped into the exhaust being burnt in the DP/CAT.... now the question is...is it coming from the turbo (bad seal on the exhaust side? or the from the motor? I pulled the IC/Intake tract and its bone dry so I am confident its not leaking turbo oil being sucked into the motor. I am going to pull the plugs again to try and determine if its burning in the engine or not...but looks like either way I will be pulling the turbos off unless I can verify the OMP is pumping it in. Arrrgh.
