Oil on Water

[Mr Cerbera]

Wotcha Peeps - and particularly you Mr. Messling.

7 years ago we were fitting Oil Temp Guages after a Group Buy and discussing where to fit the sensors.

At the time, Peter, you had used an Oil Filter Sandwich plate - which I thought was a good iea
BUT
When I looked, at the time, I couldn't see enough space to fit it.

I was having a rummage this week and thought "What on earth was I thinking ?"
and I now see that there is ample room.

The problem is.... I stored the Sandwich Plate details that you recommended but it has disappeared from Ebay now
sooooooo, I wondered if you could recommed any of _ these here_ for an AJP 4.5 ?

Thanks Mate and, in fact, anyone

Half of those seem to be to add oil coolers into the circuit, which the Cerbera already has, and it (usually) does the job slightly too well on the V8s. You could fit an oil stat and to help the oil warm up and use the oil presure gauge as a guide to when the oil is warm or not.

[Jhonno]

Oil thermostat is a good shout on a Cerb..

[morebeanz]

I thought it was Peter who sorted the oil thermostat too?

I have one sitting in the garage unfitted still!

[ukkid35]

I thought about fitting one, then I remembered that I hardly ever drive the car when it's cold

[Flatplane8]

I thought about an oil thermostat many years ago, but someone (could've been Andy at APM) said the problem would then be that the cooler would be bypassed a lot of the time, possibly leading to sludge build up in it.

I have a small block of foam insulation covered in duct tape that I slide in front of the oil cooler every autumn and remove in the spring. This seems to do the trick. I do recall driving to Bristol down the M4 one winter for work (after fitting an oil temperature gauge) and being quite surprised that the oil never got out of the 'blue/cold' zone. Hence the Heath Robinson foam block.

I wonder whether the path of the coolant from the pump across the sump to the passenger side head has any interesting effects when the engine is cold

Does it heat the oil?

Does it mean one head is cooler than the other?

[pmessling]

Yes was I.

I used the sandwich plate for the sensor and a test point so I can add in a gauge should I need too in an emergency

The oil stat can be specified with different opening temperatures, originally installed for quicker oil warm up on cold days but mine doesn't really get driven in the cold any more.

The sandwich plates are pretty much all the same. Come with the four adapters for which ever filter is fitted.

Cheers Mate

Have now ordered it - YeHaaa !

Don't forget that the oil goes directly from the pump to the oil cooler, before returning to the engine via the filter, so you will need to change the hose routing to install a thermostat

Well, you know that I'm dumb

Sooooo
Why would I want to install a Thermostat.?

The sensor (and guage) are only there as observers.
I did not intend them to take an active part in changing the warm-up (or any other oil) procedure.
Am I missing out on an opportunity to blow-up my engine here ?

[CerbWill]

To warm the oil up faster and keep it at a reasonable temperature.

The Speed Six engines use an oil to water heat exchanger so the oil is heated up to, then held around the water temp. The V8s use an air cooled oil cooler just infront of the radiator on the left hand side. The cooler is sized to cope with track use, so on cold days with normal road use the oil in V8s doesn't get warm.

Adding an oil thermostat into the hoses to/from the oil cooler allows oil to bypass the cooler when cold and keep oil temps in a sensible range.

Thanks Will You're a STAR

Guess I'll have to put that on the back burner then
( but, as it has taken 7 years to get this far, I think that I'll have to leave that in my Will )

Do you think the path of the coolant through the sump may have a similar effect?

Oh Mate ! Wotta disaster !
Did I misundertand summat when you gave me the URL for the Sandwich plate ?

Coz the one I've received is COMPLETELY the wrong size !!

[Gazzab]

What problem are you trying to resolve with a sandwich plate and oil temp gauge? The ‘take it easy’ for a few miles and give it full beans after 20 minutes is ok in summer months. In the winter there isn’t enough grip to use the revs anyway.

[Mr Cerbera]

Hi Gazza

Nice to hear from you

As you will know from your long-term Cerbera ownership, you can be tootling along as beautifully as an arrow through....etc
when, for no reason in particular, "A Noise" makes itself known.

If you're picking up the papers from the Newsy down the road it's not going to be a problem.
If, however, you're pulling out of Cerbere, France and you're looking at trying to beat the TGV home, an annoying "Noise" can give you a myocardial infarction strong enough to drown out any AJP aural distraction.

The sensor and guage would just help me assess the possible depth of imminent disaster that could be approaching.
(Plus, I would like to comlete the job which I started seven years ago )

Have a FAB Mothering Sunday

Thanks for the photo of yours, fitted

What I don't understand is how you put he filter back on the Housing ?

The Housing thread length is 16mm....


But the Sandwich plate is 29mm....


Did you make some sort of Female/Male adapter or summat ?

I hope that you've calmed down since you said "you can stick any help .... up your arse"

[plasticman]

I think I must be missing something . Why would you use a sandwich plate at all ? You are going to way over complicate the oil pipework . Just fit the thermostat where the 2 pies to the oil cooler are at their closest which is probably in the front of the passenger wing out of sight .

[TwinKam]

Paul, that threaded pipe unscrews, and you should have received an extended one along with the sandwich plate to replace it.
To clarify your intent, are you fitting a temperature gauge or an oil thermostat?
If the latter, Plasticman has suggested a more elegant solution than the sandwich plate.
If the former, is it not possible to drill and tap the OE filter head to accept the sensor?

Edit: The link a few posts above show 4 adapters, one of which will screw on to the existing thread extending it in this instance, rather than replacing it. Did you not receive these with the sandwich plate?
