Important oil cooling problem with the stock 7mgte

the stock 7m oil cooling unit is crap IMOP! no one should run their car with the stock unit. let me explane why. The stock cooling system is on a pressure relief valve. what this means is that your motor has to hit x amount of oil pressure before the oil will get to be cooled and the oil thats cooled will not be filterd. not to mention the oil cooler is only like a -3 or -4 line. If you look at the next pic

you can see how this works. you have to use a oil filter relocater to drop a 7m in a mk2 so instead of just adding the kit to the stock system ie where the filter went you should take the oil cooler relief valve of and stick the adapter straight to the block. you will have to take a threaded nut of a 5m or 7mge so you now have something to thread the adapter onto then run -8 lines to you remote oil fillter, then to a new bigger oil cooler and back to the adapter. this way all your oil is filterd and cooled all the time at idel and at full wap. i run my car this way and i have found that i have lower engien temps then most. i have yet to prove its do to the oil cooler but if you think about it where would you want to stick your cooled oil back in the system or into the pan. it just makes sence and you dont have to drill a hole in you oil pan to have a oil cooler return line.

Good posting Dave. Since I knew that Jim K didn't have an oil bracket on his 7mgte, I don't either but will add oil cooler and filter relocation kit. I figured that since I don't drive much or very long, don't need to worry about oil temp. Meanwhile, if it does get hot then I'm sure that Amsoil synthetic oil can handle the extra heat!
