Oil Pressure Regulator

As I am cleaning and checking things, is there any caveats I should be aware of regarding the Oil Pressure Regulator? I have 39 PSI at the sending unit on teh passenger side of the engine. So I figure I am OK. I am not wanting to pull it but since I had some rather thick sludge in the bottom of my filter case and some build-up in the lines when I took them off, I thought I had better ask.



I did notice that there are some older threads that state the filter is actually fitering only a small portion of the oil flow. Some here even go so far as to suggest that the filter can be removed and the two line holes plugged.



Some users took the middle road and state that a little filter is better than none.



Some users took the other end of the line and state it needs to be there.



I am understand all three view points. I am going to stay with a filter as it was OEM.



Thus, my question above.

    40 psi is normal for the stepdown 6's at operating speed

    as you stated there are several opinions on the merits/draw backs of the filter and you have made your decision, good luck with your choice.

    as for OEM on the filter, it was an accessory, most likely by the dealer. the cars left the factory (typically if not always) with pipe plugs in the ports.

    IMHO, the easiest and safest way to clean the engine of sludge is to drive it and change the oil and filter every few thousand miles.

    You checked your oil pressure at the correct place, you can be sure that is the real operating pressure. Like has been said, 39-40psi is fine.



    About every oil filter of the time was a by-pass filter of some sort or another.



    Its better than nothing.



    My '49 has an oil filter. The Wasp does not. I keep a close watch on the Wasp's oil and change it at 2000 miles or less - whatever is conveinient.



    The reality of by-pass oiling is, the oil being picked up from the sump does not get immediately filtered before it goes through the engine's bearings etc. The idea is the by-pass flows more oil through it than the engine is using through the bearings etc. , therefore the quantity of oil gets filtered "before" the oil pump picks it up. In theory, the only oil available to the engine has been filtered and returned to the pan.

    Understood.



    However, if one were to remove the regulator, what should one look for?

    Regarding keeping the oil cleaner, if you ever have the oil pan (crankcase) removed for cleaning, etc. (the manual tells you to do this every six months!!), it can't hurt to install some magnets in the bottom. These will pick up metal filings, etc. that are floating around in the oil. They really do work, it's amazing how many damaging particles they can remove from the oil. That's why most automatic transmissions use them. You can get a set of round ones from Radio Shack for a few bucks. They resemble really thick 'washers'.

    Excellent piece of advice.



    Sure wish I had thought of that before buttoning up the 308 in the '49!



    Isn't it possible to find magnetic drain plugs as well?

    Thank you.



    Back to the original question.....Is there any thing I should be aware of before removing the regulator? As I am in the process of taking a few things off to check and clean, it is "on the list."



    Did Hudson send the engine out with the regualtors installed and the plugs installed?

    You can place a strong magnet outside the oil pan for the same effect.

    Engines were sent out by factory with regulator in place (otherwise pressure wouldn't be regulated) and plugs in place if no filter was installed. I can think of no issues with removing, cleaning and replacing regulator.

    Thank you, Fred. I see now that I asked a silly question. I meant to only inquire about the plugs.



    Out it will come, cleaned and inspected it will be then I'll put it baack where I got it.:)
