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?

Lawsy

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.

Hi,

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.
