1st Gen section didn't have much to say so I'll try 2nd gen section.

Any of you guys that remove the OMP and run premix, did you remove the OMP drive gear and shaft? It appears most people leave the OMP shaft installed--prehaps cause they don't want to go through the trouble of taking off the front cover. I'd like to know if anyone has miles on their engine without this shaft installed--and of course running premix?

I'm doing the TII conversion into an GSL-SE. Planning on running straight premix and thought why can't I use the OMP mount connection for my turbo oil drain (FBs don't have a turbo drain)? It's in roughly the right spot and seems like it would work OK.

I see only one problem and it may not be that bad. There is an oil journal that runs from an inlet in the opposite side of the front cover, through the front cover, and then feeds the OMP shaft and pump with oil. I presume the excess oil just drains out the gear end of the shaft and a little hole that is drilled on the OMP mount. If I remove this shaft the oil will have no restriction and would result in less backpressure on the oil feed system--since the oil can then just drain back into the pan via the front cover. From what I can tell the OMP is the last component in the lube system before draining back to the pan. Would the oil system just adjust and feed more oil to get the same system pressure drop? Definitely don't want to screw up the the oil system/engine.

Thanks in advance for your help.

That's a good question. And I don't know the answer....but have you considered that when you put the front cover back on (assuming its off) that you put a piece of gasket material over that very small hole in the front covers left side when you put the cover back on. That should stop all oil flow thru the front cover to the omp. Not the answer to your question, just a way around the problem. Sorry, I don't premix anything, including my whisky.
