Official Gen III Block Thread
I just received my Gen III block and figured we could have a place for all of the Gen III block questions.
So, I am curious how everyone ran their oil cooler. Pictures? Thanks!

The oil cooler has two purposes on our car- warm the oil up to temperature faster and then cool it if it does get too hot. Oil temp rises at about 1/3 the speed the coolant rises, so getting it up to temp faster dramatically helps the PCV system work by burning off water/fuel in the crankcase.
If you run a cooler without a thermostat you really hurt the cars ability to truly warm up (oil fully warm not coolant) as quick, compromising the integrity of the oil by being over contaminated with water. It would be interesting to do a test on the differences in oil warm up time with stock oil-coolant heat exchanger, no oil cooler, and an air-oil cooler without a thermostat.

Ill be looking to add an air type oil cooler as well, but on LSJ block, the main reason is I dont like the bulkiness and location of the factory cooler.
My concern is what to do about the factory coolant lines that go to the oil cooler, should I just swap to a gen 3 Tstat housing or what?

i thought you bought an ldk? ldk is still considered a gen 2 if im not mistaken since its essentially an lnf. either way im pretty sure the gen 3 some blocks have oil coolers for the 2.0 regardless. its like the older le5s some have them some dont.
none the less as ive seen on the forums you cant just drill and tap the holes either for the exsisting oil cooler. if you did that there wouldnt be any pressure. gm has a sleeve in there ive had to machine before to make the non oil cooled block adapt for a oil cooler.

I have talked to Mr B about cutting off the oil filter housing and mounting it there with a remote mount filter. I was wanting to see everyone else's before hacking of a part of the block haha
