Oil cooler/accumulator Question

[S800VXR]

Looking to fit an engine oil cooler to my LS3 along with an Accusump setup. Likely to tap off the oil filter where there is a transfer cover plate above the filter itself.

My question is... Does the oil filter assembly have a none return valve setup so that if I tap into this cover and force oil back in before start up will it actually go around the engine or simply back feed through the oil pump and into the sump.

Hope that makes sense. This is the area I am talking about BTW.

Started to investigate this before on the VXR8, before I found out that the oil temp gauge was naff. The Camaro uses a cooler, and the takeoff is the place that you've identified.

Good place to also put a pressure sender

So long as you fit a thermostatically controlled oil adapter you won't have to worry about low oil pressure on start up slow warm up. I've got a Mocal oil cooler adapter fitted because the Improved Racing thermostat adapter was still being developed. Otherwise I'd have bought one of those with their sump baffle parts.

Cheers, looking at this currently which will support the thermostatically controlled cooler. The question though is if I T off the out line will the Accusump push oil back around the engine via the internal bypass of this unit when cold or will it back feed through the filter and pump into the sump. Granted there is some restriction through the filter and pump but I'd like to understand if there is actually any none return type valve in the direction...?

Almost all oil filters have a non return valve in them.

Just take a look, if there's a little flap of material blocking the small oil holes, then you will not pump oil back through the filter.

What size hoses are most of these oil cooler kits supplying ?

The main oil galleries in the engine are approx 12.5mm give or take a little.
Whilst I see places in the US selling parts using -10 pipework etc, no -10 pipework actually offers a bore size as big as this when the fittings are taken into account. I think the biggest I measured a while back is around 11-11.5mm

They seem to work...but I dont like the notion of reducing sizes of these main oilways before it even gets into the critical engine bits.
-12 takes it up to about 14mm.

Actual flexible hoses are larger, but by the time the fittings are inside the hose, they reduce the actual diameter available for flow compared to quoted hose diameter.

^^^ I didn't add enough info as I was just getting ready to drive to a drag event today. There's no non-return valve in the filter setup simply screwed to the sump take off.

The plumbing gets complicated with a thermostat oil take off and an Accusump. I was looking to use the oil prime port on the front end of the block near the oil pump to plumb in the Accusump.

I was struggling for space on my converted car so sold the Accusump instead and fitted the oil scraper/baffle only (inferior F-Body sump). I did almost exactly this on a kit car with an Accusump and a Toyota engine for years and never had any issues.

I'm looking at -10 minimum size really. The extra couple of litres won't hurt either I suppose till oil change time (extra cost that's all).
Will wait to get my car back from the Fish and crack on with this I think.
Cheers all.
