Accusump install
 

Does anyone know what kind of fitting I need for the oil galley plug? I need an -AN hose adapter there so I cam plumb up an Accusump. Are there any concerns about using it in that position to pre-lube the engine? Because it'll be downstream of the oil pump.


Thanks!

I think its M18x1.5
This thread contains info about running a accusump.

Please share info and pics of your install.

I got one of these and can confirm it fits. right next to the alternator. they recommend 1/2" lines but say 3/8" would work. just looking at it, the gallery looks like its 3/8"

Sooo
This should fit?

Wow, I had no idea that these engines had such variable oil pressure! No wonder my BRZ didn't come with an oil pressure gauge - it'd freak out the customers. I mean, holy cow, it's all over the map - 125 cold to 15 PSI warm idle?! There's no way an accusump can maintain oil pressure when it's swinging all over the place like that. Not the 3-quart model, anyway. Otherwise the oil level in the engine is going to be all over the map as well. Am I missing something here? Either you're 2.5 quarts low at 7000 RPM or 2.5 quarts over-full at 1000 RPM. Or a little of each perhaps.

Accusump also make a 1-quart model that might be a better choice for these little engines. The 3-quart accusump was fine in my V8, where oil pressure stays in a 40-PSI range. A 1-quart sump can still pre-lube the engine and provide some high-rpm stability, without making the oil level vary so much.

if you test and find out something, keep us updated, interested in this as well.

While I've never run one of these, there have been multiple reports of leakages and failures on pelicanparts and rennlist of these failing and leaking hot oil in the interior of 944's. Just a heads up. This may not be an issue on the 86.

Every Accusump (3) that I've had leaked initially. The are a pain and generally provide very little protection; based on actual testing by me and others.

I have the opposite feedback reading my accusump system in the race car.

Two things I enjoy seeing is 1. going around the sweeper here and seeing the system dumping oil in ( and saving the motor ) and 2. Seeing it dump oil in as soon as the fuel pump is trigger when I crank the car from cold.

Have had it sitting for 6 weeks and didnt drop any pressure.

You can get an electric accusump valve that will trigger at 20-25 PSI (it will discharge below that).

Regardless of how it gets activated, be careful with this engine and dumping too much oil in the case.
With a boxer engine if you WAY overfill the case, you will have oil behind the pistons when you go to crank it.
I have no idea how much you would have to overfill this case to be a problem though.
And with a "3 Quart" accusump, you do not get all 3 quarts of volume out when discharged.

And where you plumb an accusump INTO the system is also important.
For example: you might be tempted to plumb the accusump into the most convenient place like in an oil cooler loop.
BUT consider where is the oil system most likely to fail.
Dont plug the accusump into a place that is most likely to fail, or if that failure occurs the accusump will just dump out on the ground with the rest of the blowout and not help the engine.

So a good place might be where the oil goes back into the system from the oil cooler, but use a one-way check valve so that IF the cooler blows, the accusump will maintain the pressure to the engine for a couple of extra seconds

Accusump should go straight into the gallery plug, not the cooler.

No check valves necessary.


To the OP, im doing the same thing, with the same fitting from Summit.

D

But where does this "galley plug" feed?
Has anyone located it on a oil system diagram? :iono:
If we dont know precisely where it feeds the system we still dont know if an external oil cooler might benefit from a check-valve or not.

Gallery plug has no effect on the cooler.
It ties in to the main baring feed.

lot of engines dont uave this so they have to use a sandwich adapter and tie in at the filter.
