Oil thermostat question

[spiller]

ive asked similar questions about this topic before but I now have a very specific application to ask about...

I am considering using on of these Earls sandwich plates - its an adaptor to fit oil lines and a thermostat all in one.



Now, usually when you hook up a full flow oil cooler kit, you include a remote filter relocation as well - I do not want to do this because my filter can be easily reached and extra lines and fittings for this take up space and complicate things. I simply want to put that sandwich plate between the engine block and the oil filter, and two oil lines to the cooling core.

Now, the americans tell me that with this set up, the oil is not filtered before it goes to the cooling core and thus you have dirty oil entering your core, is this a problem? (i mean technically the oil is still passing through the filter, just not right before it goes to the core). Most of the japanese kits use this type of thermostat rather than an in-line style from what ive seen.

insights are appreciated!

Unfiltered oil entering the engine is bad. Unfiltered oil entering the cooler is not - unless your oil somehow contains rocks or something? Seriously, how is "dirty" oil going to hurt a cooler, which is essentially a bendy metal tube?

there is also the chance that you can pick up a stray metal filing from your core, its better that the oil is filtered as close as possible to it entering the engines oil circuit.

this is what i was thinking, as long as it is being filtered at some stage (which it is bcause the filter is in the factory position effectively). and if those thermostats were so bad/unsafe, then why would reputable companies like earls make them in the first place.

i just needed to hear it on australian turf, as we all know the yanks are known for "overkill"

I bought a thermostat/adaptor in one from VPW.

Haven't tested it yet, but it cut down on a lot of oil lines.

Cost about $80
Part number was HAY-205 from memory. Can't find it on their site though.

ah yep, this is what im talking about. its by far the simplest way to run a full flow cooler with thermostatic control. the earls adapter is 95 US but i might just get it anyway since i cant find the mocals ones anywhere...

There's a better way to regulate the oil temperature ->



A water-to-oil heat exchanger. It keeps the oil temperature stable as it follows the water temperature, and helps the oil warm faster after start. Apart from the water plumbing it's a more elegant solution.
I also quite like the WRX oil coolers.

my mid 60s Volvo 1800S had one of these......




The adapter CrUZida shows uses a bimetal spring to open/close the adapter. Mocal makes a similar unit, their thermostat is a bit different

Where's the cheapest place to get the mocal stat?

Billzilla, water to oil is a bit of overkill for me as the car is driven on the street mostly but I just want some temp stability at practice days where i'm doing no more than 8 laps per session
