Does this letter code mean anything to anybody?
How you remove the oil pressure relief plunger? I have the cap and spring out, plunger won't come out. I tried a magnet, but no luck.

Well I got that wrong- ECAAACE is the code, stamped up by #1 bore.

I only see two A's. Spray some carb cleaner in the bore on the relief valve, preferably so that it is soaking in it and after a while tap it down just a hair to try to break it loose then try the magnet and hopefully you can start to work it back and forth. Probably frozen in with carbon and old baked oil. Use the carb cleaner to break it loose then some WD40 after that to lube it as you continue to try to move it. WD-40 is also a solvent.
