Looking for a oil pressure relief valve located in the oil filter housing.

Not mine. Here is another one in Utah. Ive seen this one in person. Its definitely worth saving.   http://www.ksl.com/index.php?nid=218&ad=25572011&cat=&lpid=&search=conquest&ad_cid=10

Our red '87 had a fail safe thermostat installed some 7/ 8 years ago. Well, it finally went bad. I know cuz I open the radiator cap and saw the coolant just flowing freely.   Imagine if it had been just a regular unit? A blown headgasket would follow. Well worth the extra fee bucks.
