Oil cooler diverter valve

Ca technologies are doin a good deal on these diverter valves they are just over 50% at 55 quid a steal so ive got one for mine.
What they do is remove the thermostatic valve in the oil filter housing allowing the oil to circulate round the cooler from a cooler temperature keeping down oil temps on track.if you want a valve just mail Ca mentioning the register and he will hook you up
Ive got one for mine and takes minutes to fit easy job

What did I say to you the other day LOL?

Order me one and you can fit it when you do the breather :blalalala:!

Hopefully they haven't dispatched yours yet :clown:!

Sounds interesting :thumbs:

Keep em peeled as im gonna do a fitting thread lol
Not that its a Sunday afternoon job but at least you guys can see them being fitted

Dude 55£ is a deal for everyone mate i can get you one out tomorrow don't sweat lol mike you can order it yourself if you want.there is no group buy discount he has dropped near half way for us as is
Let me know and i will get you one

Seeing as you'll be fitting it, you might as well just double up your order :supz:.

Order me one Adem . @ £50 it's worth a punt

For you guys worrying about track temps, have you fitted a Motorsport/tropical water stat?

The high track temps won't be cured with ANY of these ideas guaranteed. Bigger oil cooler won't solve it either.

The idea of better airflow migh work and I think I might try to bonnet lift idea before I do the aux fan delete/electric fan install.

But will obviously help to reduce temps up to the heat soak point.

Not following your logic here at all.

Oil temp is oil temp, so when the oil reaches
95 degrees the oil stat opens, when the oil
is cooler than 95 degrees it closes.

If you remove your Oil stat then it takes longer
for the engine oil to warm up from cold, and most engine
damage occurs with cold oil not hot.

On track your oil is up to temp, or higher, so the
Oil Stat is always open so I am not
sure how the Oil stat closes for Track use if higher
oil temp is the problem.

Point being is that if your engine oil temp
is lower than 95 degrees and the Oil stat is
closed then you can not have a high oil temp
issue.

Hi Danny,
The way it works on the S54 engine is that it doesn't release all the oil through the cooler when it gets hot, so this is why you get excessive oil temps on track, as the oil cooler isn't being fully utilised. The diverter valve ensures that all the oil is passed through the cooler, which should mean it maintains the temps at a more acceptable level.

Obviously as mentioned, it takes longer for the oil to warm up, but providing you monitor the temps and don't go yea-ha before they're up to normal operating temperature, I can't really see the problem.

Given the cost an ease of reversal, I think it has got to be worth a punt as the oil pressures drop really low (as you know) when the oil temps get really hot, which means the VANOS is put under strain as well. I'd rather wait longer for oil temps to reach their optimum than worry about excessive temps on track.

Hi.

I am not sure I folllow any of this any more.

The Oil stat in the S54 Oil filtre housing
is controlled via a spring return stat that when closed
pushes the oil across the to the other side
where the Oil cooler return is, which in turn feeds
the distribution block for the oil galleys.

When the stat is open the oil flows into the
oil cooler and back to the distribution block.

When the Oil Stat opens oil pressure does not
alter or drop theerfore the flow path with the
Stat open will take the majority of flow and volume
of oil as opposed the oil flow path when the
stat is shut.

Oil flow is similar to water flow in that it will
always flow in the direction of the least line
of rtesistance, which with the stat open is
straigh on, not acreoss the 'bridge' as when
the stat is closed.

[Oil pressure is measured via resistance, flow and
oil viscosity]

Hence my point Oil temp is oil temp, so in order
to achieve a greater oil flow you require a larger
id bore and or a greater pressure, otherwise the
volume of oil going thru the Cooler with the stat
open is pretty much the same as the amount of oil
going diretly to the distribution block with the
stat closed.

You also mention Vanos which is the second from last port of
call on the oil feed supply chain.

If you have the Oil stat removed and in effect
a blanking sleeve fitted, on start up not only
is the oil much cooler for a longer period,
not particuliar good, but your having to
pressure up the oil cooler and oil cooler lines before
oil is fed up to the Vanos, and then Cams which is not the
case with the Oil Stat fitted.

You want the oil to the Vanos and Cams as quick
as possible on start up, not start introdcuing
delays.

There is no free lunch, and if you think that
50 or 60.00 pounds is going to drop oil temps
on a S54 at being ragged on Track then fit them
in, I'ii just stick with my oil to water heat
exchanger which works fine with the Oil stst
still in place.

Hi,the description i wrote was a basic 'this is what it does'i included the link to CA which goes into detail of what the valve does.
I see your point Gorilla but i also see mikes too!
It does increase the amount of oil flow through the cooler and this diverter is prob not a good idea on a road day to day driving car!however!!
If the oil temp raises to 125 degrees+ on track before the stat opens the surely if there is no stat present the oil cant reach that temp in the first place???it will stay at 95 degrees.track use!!m going to try one and record the info and let you know how it stands!


They have put time and money into research so im sure it must work(for some engines)!!

This contradicts your reasoning behind the motorsport water stat though?

This contradicts your reasoning behind the motorsport water stat though?

That was exactly what I was going to say, but for a different reason LOL.

If you're using the same feed as the OE item for your water cooled Mocal item, which as stated limits the amount of oil it allows to flow past it, then surely your cooling method will be no better than the OE air to air item, as the issue isn't actually airflow through the oil cooler, but the amount of oil it actually allows to pass through the oil cooler?

I don't understand how your cooling method is an improvement?

Hi Lawsy,

Not sure how.

55 degree water stat is so that the
water path / cycle opens and stays open and so the thermosat [std one]
is unable to fluctutate, once open it stays open to
ensure that no hot spots in the cross flow of the
water jacket of the head might or could occur.
[split seals/HG failure/ cracked head and so on]
and that water temp is more even due to the fact
that the lower rated water stat is more constant
for all round flow and temp.

With the Oil temps the removal of the Oil stat
is almost the opposite where on long straights
the oil temp as its always passing thru the oil
cooler and is ambinet air temp cooled could
drop down to temps where the oil is at it
weakest in protecting internal engine components.

Back on the twisties and its rising again, and so on.

Thus you create surges in oil temps which
is not good as their is no stat to close when
temps start falling below 90 deg ti try and
hold the temps more even.

F430 458 New M5 the list goes on all are running
oil to water heat exchangers, many no longer
run a std air cooled Oil Cooler, as they aim to try and
keep oil and water temps as constant and even as
possible.
