oil cooler vs non oil cooler

Hi guys have another question to put out there. I am doing a jdm engine swap on my 2001 tacoma v6. My original engine had a oil cooler. The replacement Japanese engine did not have an oil cooler just a cover instead. I would like to reuse my original oil cooler but.....
my original engine block has a nipple for the hose to the oil cooler. The replacement Japanese motor has a allen plug instead of the nipple. The plug is becoming a nightmare trying to get it out without stripping out the inside of the plug. You all know what is about to happen. To avoid this nightmare from happening is it necessary for the oil cooler. Does anyone know why some engines have it and some don't. For how little the oil cooler is does it realy make a temp difference.
Or does some one know a sure fire way how to get the plug out. I have soaked it with WD40 and heated it with a torch.
Any thoughts or help is appreciated.

 

the difference is car motors dont have oil coolers. The swap over for my JDM conversion was pretty straight forward look for "JDM Motor in 2002 DCSB SR5 Prerunner" as I cover all of the problem I encountered and then some.

 

were you able to get the plug out of your jdm engine

 

yes, see my reply in th JDM Motor post.

 

You could always weld a hex nut on it. Also try to get some real penetrating fluid in the threads. I like 50/50 acetone and atf - it's been tested to penetrate better than anything you can buy on the shelf (because ?).

 

high jack thread here ... I use parafin wax. A little heat and it travels down the threads and when it cools you have a lubricant as you remove the fastener. In my experience with other lubes, PB Blaster, WD etc. if the fastener is close to galling as it comes out with parafin it doesnt, with the others the higher the friction the hotter it gets and the others burn away. But having said that it is impossible to "know for sure" because what are you going to do, put the fastener back and try something else?

 

I think you can get one here. The kit attaches to your spin on oil filter.
