actually i was thinking why not just bypass the oil cooler and get the shorter threaded rod and run no oil cooler to see if that fixes the problem?  you'd still leave the coolant lines hooked up to the cooler...

So I flushed the coolant and swaped in a brand new oil "cooler" now I will try to get rid of the oil by replacing the coolant a few times and we will see what happens.

Please let me know how replacing the cooler works out for you...i just got mine running today and am having this exact issue. I've tried flushing the coolent system twice with water (didnt seem to do much but hard to tell if I got all the oil out), bypassing the cooler by hooking the 2 coolant hoses together (seemed to make it a bit better, but there was still a little oil), drained about a litre of oil (no coolant that i could see...nice solid black with no foam at all). The coolant wasnt super gross but it definately lost its nice transparent green and turned milky, i could see little oil droplets coming up the overflow line and into the bottle.
I have a couple of air/oil coolers kicking around that i'll try to hook up to see how that works. Any tips for fully washing the oil out of the cooling system?

i'm not sure if it is advisable, but orange cleaners REALLY cut the grease...  they might do other harmful things to the motor though.  i would stick to one of those heavy duty coolant system flushes.  basically get all the coolant out by back flushing, fill up the coolant system with a hose and pour in the bottle of coolant system flush.  be sure to have the thermostat installed.   then run the engine for 10-15 minutes to make sure it gets nice and hot.  i had a nice brownish liquid coming out of mine  :lol:

I have used castrol engine degreaser concentrate to the cooling system.  It breaks down the oil and flushes the system out perfectly. ONkly need a few cups.

is this an okay procedure? won't wreck anything inside the motor? just curious...

Could the car be driven to a service station so that they can flush the coolant system and add new coolant?  Many have a machine that they hook up that automates the process.  You'd also keep antifreeze from leaking everywhere.  If you wanted to do it yourself, parts stores sell flushing kits that contain plastic adapters for the garden hose and drain line plus the chemical for the flush.
