  • Engine: Oil Pressure Relief Spring

    I finished stripping my block down (289) to take to the Machinist. I removed the plug and pressure relief spring, but I'm wondering if there's something else in there that needs to come out, like a cup or plunger. Thanks, guys...

    Yes there's plunger in there. They are sometimes ornery to get out, do a forum search on the topic for advice on how to remove. I've had good luck with an easy-out gently tapped into the plunger and then a process of pushing and pulling it back and forth to pull it out of the bore. Recommend using a solvent such as carb cleaner to clean out the bore as there is likely some accumulated gunk in there.

          Easy out, PB Blaster and a lot of patience.

            After spraying with your favorite lubricant, the taper of a Pencil gently forced into the hole in the center will usually, but not always do the trick depending if it is gunked up badly or not.

              I got mine out with a small mechanic's magnet on the end of an extension wand.

                If its really stuck a little heat on face of block will help and something tapped into the center hole, and lots of carb cleaner and penetrant. Luck Doofus

                  STUDERICH - The pencil did the trick...slid right out, no gunk.

                    Tony,
                    You and your machinist are both aware of the pipe plug in the oil galley just under the distributor--yes?

                      Scuse my ignorance - Can you please explain what you mean? Is it supposed to be plugged or unplugged? What are the consequences? Cheers, Quentin.

                        It must be removed to properly clean out the oil galleries -- but MORE IMPORTANTLY -- replaced during reassembly. Otherwise you will have no oil pressure at start-up and bad things will happen.

                            ROCKNE10 - Got that one out, but the plug in the OTHER oil gallery on the opposite side won't budge...

                              Weld a nut to this non-budging plug, wait a few minutes then it will come loose, if your weld held. Luck Doofus
