    You’re welcome and thank you Joe. It took awhile and some sharp helpers from Facebook to figure out that oil pressure loss route cause. I was close to pulling the engine. Thanks god it got figured out before all that work.

    Excellent tip Joe! Ive seen this plug forgotten before just like the one that goes in the front of FE Fords. Theres another one that gets forgotten a lot and the end result is even worse... It goes under the rear main cap. I'd make a video but I don't have a small block apart at the moment. Maybe yours is still apart? Edit: then I proceed to read the comments and see this was already pointed out by other Mopar people! LOL!

    I always check with a dowel down the sending unit hole. I have one already marked at the proper depth for the plug. Also on BBs, people leave the pipe plug out below the cam gear that points down to the pan. Have seen that TWICE!! No oil pressure, so they were never driven, and one was not started, just failed to prime. They both survived, and the one that was only primed and not started, ran a 6.9000 in the 1/8th it's very first pass (440, .590 Purple Shaft, 906 heads, TeamG intake with 1050 Dominator, 2" fenderwells, 74 Dart Sport with 4.88 8.75 and J-converter) with a deer-in-headlights novice owner/driver. LMAO

      Excellent! That was the case with that blue Roadrunner in had in. They drove laps around the neighborhood trying to get it to prime 😳. It didn’t happen 😢

    That is definitely not good as you can't clean the oil gallerie..
    Block looks very nice Joe.

    This oil plug arrangement is also the same on early Chrysler hemi's , and probably all of the Mopar rear distributer varieties from the 1950's .

      I wasn't involved with the oil galleries when my dad overhauled the engine in the car in my profile. It probably has the inner plug also like you said.

    Great coverage, Joe. Big thanks to JonnyMopar for shedding some light on it.. I have seen these plugs with a tiny hole drilled in them for oiling the distributor shaft bushing. I don't know if that was really needed, but figured, as small as that hole was, it probably didn't hurt!

    This really is a great tip for all the guys out there. Thank goodness for great machine shops that generally save our bacon a lot of the time! I too have had those already installed by shops...i think for the very reason that Jonny just dealt with. I'm alot like you Joe, I want to be able to put a flashlight at one end and look through to ensure things are clean; and I've almost made this mistake before myself. A guy also has to be careful if he loses one of the original plugs not to use a replacement plug that is too deep which can cause interference in the galley. Thanks again brothers Mopar Joe and Jonny 😅💪👏👏👏

    😎👍. will have to check my LA 360 I took out of the truck a few years back . I would have good oil pressure but after a while it would lose oil pressure when warmed up. the crank bearings started showing copper and had the oil groove all the way around so that didn't help either.

  • @rickseeman5679

  • @aaronbarnes8938
    @aaronbarnes8938 Рік тому

    you can also put a .020-.030 hole in the center of that plug and you get pressurized oil to the distributor drive gear and helps them live longer.

  • @richardbeals1403
    @richardbeals1403 Рік тому

    There is also a drive in welsh plug that goes in from the bottom under the rear main cap. It directs the oil pump output to the filter, if it isnt in the oil will never flow through the filter. It is in the passage under the oil sending unit port.

    • @JustMoparJoe
      @JustMoparJoe  Рік тому

      Yes sir. I can show that in the build video. “Rodney Byrd” and “Mopars are Everything” made a reference to that. Thanks Richard.

    Oh man, such a simple overlooked oops. I can honestly say that we have all done an oops like that. Anyone who says otherwise is either a liar or never touched a wrench, haha! Hell my worst oops was breaking a compression ring and never noticing it until after it broke in the cam. Sad times!

  • @Anthony-nw5zv
    @Anthony-nw5zv Рік тому

    Ya know something, I believe it was last year or 2 years ago, Uncle Tony brought a back yard rebuild 318 to Nick's Garage to brake in a new cam and get some numbers. The oil pressure kept dropping, and Nick pulled the pan and oil pump and besides having a lot of debris in the filter, everything seemed alright. I wonder 🤔...

    • @JustMoparJoe
      @JustMoparJoe  Рік тому +1

      Lunar still had that engine. I believe Nick found out that the engine had .010 bearings on a very rough standard crank. It ran, but kept losing oil pressure for me the extreme clearance. It also had terrible blow by because they power honed one cylinder with a three stone hone trying to take the extreme ring groove out.

  • @CHEAPROLLIN
    @CHEAPROLLIN 2 місяці тому

    I had a bad valve on the rear passenger side of the engine replaced the cylinder head and now I have excessive blow By smoke out of the muffler. Is this normal will it eventually stopped once it burns all the oil out of the cylinder or or can it possibly be out of time and that's the reason why it's smoking again

    Your thoughts on the oil modifications shown on other channels where they block off one side and drill and tap the oil passages in the lifter valley and run a tube from one side to the other? Good thing to do or bad thing to do?

    • @JustMoparJoe
      @JustMoparJoe  Рік тому

      I think it's a solid idea for high rpm stuff. I can't really afford the heads to flow the high numbers over 6,500 rpm.

    How common is it to remove that plug? I mean...hot tank and machine shop maybe? Or? Probably a pipe plug right?

    • @JustMoparJoe
      @JustMoparJoe  Рік тому +1

      I like to remove it and brush that out. Especially in a sludged up engine that ram Quaker state or pennsoil. A hot tank will help, but it won’t eat that heavy stuff all the way out. I think it’s a smaller plug than standard, but they’re usually in the headache kit.
