wet sump, remote filter, themostat & cooler plumbing

[menostig]

If I've understood correctly it's routed like so:
- out of engine via take-off plate
- to remote filter housing (and filter)
- then into oil thermostat
- if thermostat closed, returns to engine take-off plate
- else into oil cooler, then back via thermostat to engine take-off plate

- with optional inclusion of an Accusump T'd in on the return from the thermostat to the take-off plate.

1. is that right ?
2. so if stat is closed, it's not a dead-end, cold oil returns to the engine ?
3. should there be a one-way valve in either the take-off plate or the filter or it's housing ?
4. where to mount the remote filter to minimise hose runs and thus oil pressure drops ?
5. anyone tried mounting the oil-cooler up against the rear grill with a temp-switched fan pushing under-clip air out through it ? (ok so it's heated air but it's not as hot as the oil, and this way around is better than the side mounted oil cooler with sucking fan just heating-up under-clip air even further, also this way helps removes potentially cubic metres of air under the clip so soon it's quite cool there).

phew
cheers

1. All correct.
2. Correct.
3. Mine does not.
4. Mine is mounted to a plate on the chassis just behind the cooling hose coming up to the swirl pot. The stat is on a plate across chassis rails above the fuel tank, almost over the fuel level sender.
5. I have no fan on mine but have thought about fitting one or two in the back grill.

Note the stat is shown mounted further back in the pics but it fould the exhaust manifold when I came to fit the engine so had to move it forward.

If you install an Accusump, you will need a one way valve just behind the T point so when the accusump discharges, the oil goes in the right direction, and not back into the sump. (I found it really hard to find AN-12 end fitted one way valves. They were all NPT, which meant adapters as well).

I don't think you do 'Need' one.
When the Accusump discharges the oil lines will all be full. If it were to discharge the wrong way it would have to force oil back through the pump which is busy trying to pump something the other way. If the engine is stopped then it may be possible for the oil to go that way but we are not concerned with that.

Having seen your pics Steve, I think I will put in a remote oil filter this winter. Changing the oil at the moment is a bit awkward. Done 6 oil changes so far, so it may be worth considering!

Hmm... I thought though that the general idea was that the accusump comes on when there is an oil pickup problem, so the oil lines would not be full. Does that make sense?

I only use the accusump as a pre-oiler on my dry sump system. I was wondering if when the dry sump pump is not spinning, whether it acts as a "block", which might mean I don't need the one way valve. But I put it in anyway in case that wasn't the situation.

Everything I read said you have to put one in for it to be effective. But then, that could just be me thinking "I saw it on TV so it must be true".

Your dry sump pre oiler situation may be different.

In most cases when the pump has nothing to pick up the oil lines beyond the pump will still be full as the pump is the lowest point.

The folks at Canton recommend that you fit a check valve between the accusump and any oil coolers or remote filters: http://accusump.com/acc_products/acc_

This would seem to make sense as there is a lot of pipework to compress against before you get to the pump and actually start pushing oil into the engine in a surge situation. How much difference it would make in practice I'm not sure. It depends on which path offers least resistance to the oil.
