2010 M8 - Deep Pow Bog/No Bog Poll

Prairie bound, can you explain this "oil blow back" on the Y pipe?

I'm getting a bog like I am running way too rich and I have had some oil stains/splatters over the inside of my engine compartment from time to time. Sled runs good, and I'm not getting a "too much snow" bog. But just running like it is super rich around 4000 rpm. Feel like I constantly have to clean it up by adjusting the throttle quickly. If the Y pipe isn't sealed perfectly, could it be causing this ?

no bog

no bog

its as easy as 4 1" holes on each side of your gauge. 1 going into the intake on each side and 3 for hot air escape. (they make a frogskin that goes there perfect)

ever since i did this i have not had 1 bog even in this pow!

i landed sideways and off the machine on the one pic you can see the intake mod slightly.

sled mods are listed in signature, but pretty much just a mbrp can and a little intake mod.
