OMP block off
Hi all, I'm trying to find a new spot to fill my oil.
I currently have my OMP blocked off/deleted, could I just add a bung to the block off plate and fill my oil through that? Or is that a high oil pressure point. I need a spot that has no pressure so oil doesn't get pushed up through the fill cap while driving

I'm not sure if that would work.... maybe if you remove the piece that indexes with the OMP drive gear. I can tear into a spare front cover next time I swing by the shop.
How about integrating something with the oil return orifice on the rear iron? you could tap the block off plate and run a 90 degree barb fitting with a length of aluminum pipe extended up so you can pour oil.

Collin, I was going to do that I was going to weld a -12 bung to an aluminum pipe and run the line up to about thermostat high . That's when i didnt know where to mount my lsx coils . because I needed the room ,try it and switch the bop back if it doesn't work .

Thanks guys,
I had thought about going to the rear turbo drain that I have blocked off and welding a -10 bung to it. But then my braided SS hose has to run right next to the exhaust. I was thinking if I could weld the bung to the OMP block off then it'd be away from the hot exhaust and right next to where my cap will be.
If the OMP area is an area of high oil pressure then I'll try the rear turbo drain. I was going to "Y" into the front oil drain where the big turbo currently drains, but I'm not sure if having that be the spot where air vents (the oil fill neck will double as the vent) if that would mess up the turbo's ability to be lubricated.

i suppose the supercharger had to delete the filler neck? if so you might have to modify the front cover to have a filler spout attached. or just be creative making a new filler with the stock location, pull the steel insert out of the iron and fabricate something slim to fit under the SC.

Slightly off topic, but is it a good idea to mount the ls coils close to the block in the oil filler area, or would heat cause a problem? my new engine is t2/s5 and space is a premium in the little car. Lotus 7 t2 with haltech and lsi coils coming.

You could add a fill point to the front cover through the OMP point, but it would be a ton of work. The front cover would need to come off to remove the OMP jackshaft. When the jackshaft is removed you need to plug the oil feed point in the front iron.
The question is, why are you wanting to do this? If that much oil is actually getting pushed out the fill cap or crankcase vent holes by pressure you have a bigger problem than where to fill the oil. If you have that much blow-by, and you're successfull in completely sealing the fill neck and crankcase vent ports, the pressure in the crankcase will find somewhere to escape. The next place it's going to bleed is the oil pan seal, front cover/iron seal, and main seals. And when it does, oil is going to come with it.
The first solution is good crankcase ventilation and a catch can. You can arrange the catch can to drain back into the crankcase. The proper solution is negating excessive blow-by, which requires a well built engine.

Yeah its because my supercharger inlet is where the stock oil fill neck comes up. I did some fitting, and the rear stock oil drain location will work. So I'll be adding a -10AN bung to it and the line will run to a filler that is located where the ABS used to be, I'll get some pics up once i'm done.
Thanks for the info C Ludwig.
