LS2 Oil Galley Port I'm looking to install an oil accumulator on my 06 LS2 crate motor and would like to plumb it straight into the Oil Galley on the return side. It looks like there is a plug at the very front of the block that would be the right one. I just want to make sure.
Also, anyone know the right size/threads for a fitting to go here?
Any folks here use oil accumulators? This is in an offroad comp rig and sees a lot of extreme angles.
Any help is appreciated....

I have my Accusump plumbed into the oil galley plug on the left rear side just above to oil filter output boss. It uses a 3/8" pipe thread. You need to put the accumulator line in a place where it feeds the engine directly, rather than where it has to flow backwards to feed the bearings.

Yep, the oil pressure eventually dropped really low on that climb. A new LS2 crate motor costs way too much to let oil starve.
I've thought about a dry sump, but given the complexity and cost, wanted to try an oil accumulator first. I have a 2 qt Accusump that should give me about 30-45 sec of oil pressure "buffer" in a roll over or a real steep climb.
The port above the filter boss is taken by an oil pressure sensor. The one I'm thinking looks like it's on the return line is the one at the arrow in this pic. Driver side front of the block. Does this look right?

I use that port location on my LS6 for the accusump line. The nice thing is that it is a large port, similar to AN10 size, which works great for the accusump.
Earls 9919FFJ is a good 16x1.5 to AN10 adapter (will need an o-ring to seal)

Maybe uninformed (dumb) question but can you run a very simple Accusump-one line out from sump- without any pump or electrical to serve as a oil supply backup if you are not worried about preoiling?
I would think the engine oil pump would charge the Accusump after the engine and keep it charged until engine pressure drops below Accusump pressure?

I know this is the wrong idea but the only oil accumulator I've seen for the LS2's on the GTO's (people keeping oil out of the manifold, IE EGR oil accumulator).
My thoughts would be the accusump idea and have the feeds go into the front section of the valve covers (since the motor would be at an incline the oil should feed down the length of the heads keeping the valvetrain lubed). Not sure if that would help keeping the cam and crank lubed while near vertical though?

Part number wasn't quite right, this is: http://holley.com/9919FFJERL.asp Summit carries it under that part number.
As far as running an accumulator with no valve, no reason it won't work that I can see. I have started mine with valve closed, open etc. I do know when first cracking the valve the oil pressure will dip a few psi, but at idle or cranking speed, it should not be an issue.
