EDIC timer, how many seconds?

[lostmarbles]

Thanks.

So this is that mysterious "sandwich":



And it's a device that fits between the oil filter and its holder that captures the oil flow for extra filtration, extra cooling or whatever.



Yes. I'd certainly have no qualms about dumping that!

Is it homemade or does some company actually sell these things?

 

[pedrocalima]

Exactly! That is the sandwich

After searching a lot online I figure out that there are 2 types of the "sandwiches" available.

One type is just a "spacer" that doesn't reroute the oil anywhere and is used to plug sensors for gauges. In fact one could theoretically use it for bypass oil filters I guess taking the oil from just one hole and returning it on some low pressure oil place back to the engine.

The other type (the one I had on my 3B) is a "sandwich" that reroutes ALL the oil thought one of the roses on the side and get it back from the other rose. All the oil from the oil pump HAS to go thought the detour.
Mine was is made by MOCAL that I believe is a brand for racing stuff (they also make electric oil pumps that can be used for pre-lube systems)

I think people might use this extra oil radiators for racing cars where my cold sticky oil problem doesn't apply.

I will use my truck tomorrow morning and it should be pretty cold, lets see how it behaves.

I just wish I had dumped all this radiator stuff sooner.
How bad do you think the morning "dry" starts could have damaged the engine? Sometimes on -20 Celsius the EDIC would cut the engine 4 times before the oil pressure would raise.

As I understand it, you were already running cold-climate oil (5W-40) so it's not as though you hadn't taken any steps at all to protect your engine.

And during those cold starts instant fresh oil surely wouldn't have been needed for cooling purposes.

And I bet there was still sufficient left from the previous engine-shutdowns for lubrication purposes until your sticky treacle oozed along the oil galleys to provide a fresh supply ....

Does your oil gauge still show some oil pressure at idle with the engine warmed up? If so, I'd rest easy about it.

 

[pedrocalima]

This morning the thermometer was showing -15 Celcius and after starting up the engine the oil gauge went up in half a second, I couldn't believe my eyes

Before removing the extra radiator the EDIC would cut 4 to 5 times at this temperature before the oil pressure would raise enough.

What I noticed is that the gauve show oilr pressure higher in any situation, cold start at idle, cold running, warm running and warm idle. The last case used to have the gauge sitting BEFORE the first mark on the dash, now it sits a little after it.

I'm happy now and all my plans for Pre-Lube, Webasto, EDIC capacitor change, 0W40 oil etc are no longer needed. At least not on the near future.

Not all sandwich adapters aer full-flow all the time. The one I installed on my H in this thread has an internal thermostat. Oil will start flowing to the remote oil cooler around 165 degrees F. The thermostat is fully open by 180.

The H doesn't have an internal factory oil cooler. That's why I added one when I added the turbo. I think the 2H has an internal oil cooler.

 

[pedrocalima]

That is nice!

I saw what looks like two metallic round parts inside your sandwich but I didn't realize it was a thermostat.

If that works properly it would have saved me from all the cold dry starts I had.

What is the brand of that sandwich? Where did you buy it?

Thanks

Just for knowledge's sake can someone tell me if the picture is correct?

I mean is this the right path for the oil in a 3B engine? Are those the right valves on the right places?

If yes I suppose my low oil pressure on cold mornings were due to the relief valve being forced to return the oil from the oil pump to the pan without lubricating anything :whoops:

 

[lostmarbles]

I've been thinking about those "sandwiches" and your old oil flow setup on and off too Pedro. So I'm glad to see you aren't resting either.

From my experience, older FSMs tend to supply better information.

The 3B design is based on earlier B and this is what an early B FSM shows:





Hopefully that block diagram answers your question..

[pedrocalima]

This diagram is great! I have to say that my power point was not that far

I think I understand what was the cause of my issue and that is the most important thing. I'm fore sure not messing up there again!

I think that the "middle" bypass valve from the diagram, the one that opens with 11.4 - 17.1 PSI is the internal relieve valve on the oil filter canister right?

Regarding the "sandwiches" the one RufusTheDufus used with the thermo valve should work good as it acts on start-up like if it was not there, all the oil goes to the filter and does not circulate to the extra radiator (assuming all the oil paths are big enough on the sandwich).

Thanks again for this diagram, really clarifying.

That early B-engine didn't yet have cannister-type oil filter but instead had a "replaceable element-type" as shown here:



As you can see - YES. You're right. That relief valve is indeed the one that bypasses the filter if it becomes too blocked.

And I cut one of the cannister-type filters (that we use) apart a year or two ago too:



This enabled me to inspect the relief valve that's incorporated in the element end-cover where the spring sits as shown in my next post (hopefully).

 

[lostmarbles]

So here's where our relief valve is (if I'm not mistaken):



In the recess where the spring sits:


And this means it's opening pressure could of course vary according to who made the filter..
