4ag oil cooler

I will be fitting an oil cooler from a Twincam/SX to my 4agze, the kit in question is an oil bypass cooler which directs any oil that has bypassed the filter throught the cooler and back into the sump. i need to know if the standard bypass valve on my engine has to be modified or blocked when i fit the kit?

vic you sure it puts it back into the sump?
i'm setting up an earls cooler up on mine, and, the inlet and outlet both mount to where the oil filter screws in.
one thing i found with mine, is, that if i used the sandwich type from the 100kw motor oil fitting (the thing that the oil filter normally screws to) its too short - i had to use one from a RWD 86kw type as the shaft is longer...if that makes sense...

I looked at the setup before i pulled it off the engine, the sandwich plate has only one outlet which is after a valve that goes to the cooler and the line from the cooler returns to the sump.

I am very interested in getting a oil cooler for my 2T-G also. I may have to make the sandwich plate myself. Maybe I will get the 4A-FE setup and modify it. I have looked at the 4A-FE on some AE92's, and they have a sandwich plate. Oil line goes from that via some valve, to the oil cooler, and back to a banjo fitting on the side of the sump.
More info on oil cooler please, and oil temp and pressure gauges. I don't want to kill my new motor.
Where does the oil filter fit in the normal oil circuit? Is all oil filtered? or just some?

Jonny, how keen are you on having a thermostat in the cooler system? If you dont need it, then motorsport connections offer very well priced sandwich adapters with 1/2" NPT connections for an inlet & outlet to a cooler. All oil still passes through the filter.

I need a water thermostat. But I don't think I need a oil thermostat. Is that what that valve is on the botttom of the 4A-FE base plate? I will need to look at my engine again. Does the oil just go back into the sump after the oil filter? If so, I can have the oil just go from the filter to the cooler to the sump all the time right?

If you go for an aftermarket sandwich plate, all of the oil will go through the core, and the filter, then back into the motor, not the sump.

There's 2 types of oil cooler systems, high pressure or low pressure. With high pressure (the one phil just described above) all the oil flows through the cooler before it goes through the filter & then to the motor, so the cooler & it's associated hoses are under full oil pressure.
With low pressure, a thermostat is used to bypass some of the oil away from the motor & through a cooler & then returns it to the sump, but only when it's hot enough to open the thermostat.
There's good & bads in each system.

my 4AGE is running a 1118 earls adaptor which bolts to the block - this then has a hose which travels to a remote filter mount (ford z9 or std 2T filter) which then goes to an oil cooler mounted up the front. from the opposite end of the oil cooler, oil returns back to the 1118 adaptor on the block.
these setups are not cheap. when you start adding up hoses at over $20 per meter, it gets quite expensive. but worth it in my mind - cheap insurance.
jonny - you could use the 100kw type setup on your 2T - earls say that the 1118 is supposed to fit the 2T - sure it screws into the block, but, its about 2-3mm not wide enough so the rubber seal doesn't seal up. i have one of these 100kw type bypass sandwich things if you're interested - i won't be needing it.

So is the valve on the side a thermostat not a by pass valve?

It's a thermostat that bypasses oil. 
So yeah, it's both, a thermally controlled bypass valve.
