Relief valve in rear of FE block? Did I miss something?I didn't see a spring or releif valve in my 427 FE Side oiler service block. The only releif valve I saw was the oilpump releif valve spring.The vented plug behind the timing chain gear to vent any trapped air in gallerys and squirt oil on chain

Mike it is the high pressure relief valve in the rear of the oil galley.
It blows off oil back into the pan when the oil pressure gets to high. I don't have a picture handy. I not sure but your service block should of had it too. There should bee a couple of allen plugs where they Machined the oil passeges from the rear to the front of the block. There's three around the cam plug and the two down the leftside. This is just from memory so you might want to check out some other resource or maybe someone can post a photo hear.
