Guys I'm trying to install an oil cooler for my 81 928S...I have a radiator (oil) laying around and was looking into purchasing one of those universal adapters that goes on were the oil filter fits when I came across this posting. I'm not quite sure were these 2 holes are drilled on the engine and would it be just easier and better to go with the adapter or should I do it the proper way and unplug these holes and buy whatever is needed. What do I need to buy and from whom ? I also noticed talked of a thermostat. Where would it fit ? Thanks.

Install the thermostat pieces. Find a used block and steal the fitting out of it to insert into your own block, instead of the two plugs. Install a radiator with a cooler on the driver's side. Install a set of oil cooler hoses. I make replacement hose sets out of hose with PTFE lining with the original German Hose Ends (exchange your leaking old hoses, only). Bullet proof.
If you can't find a block to steal the two fittings out of, I stock metric to AN adaptors for both the block and the radiator in -10, -12 (prefered), -16. By doing it this way, you can run hoses with AN hose ends, instead of the German hoses. Eliminates the "need" to find the block fittings and a set of "original" oil cooler hoses.
Beware: The threads into the block (actually the block cradle) are notoriously fragile. The plugs or fittings almost always have Loctite on them, which is actually what causes the problem/damage. Removal of the plugs/fittings frequently will "break out" the leading edge of the threads in the block, requiring some "special tricks" to get the fittings to seal. Do yourself a favor and heat up the plugs with a torch, before you attempt to remove them. Get them hot...a propane torch will not get them hot enough. Heat destroys the Loctite bond and they will "jump" out of the cradle.
