Oil Regulator Question (1 Viewer)

[Coolerman]

Here is a pic of my cleaned and blasted oil regulator. The piston or valve which ever you want to call it has some wear marks in it and was adjusted ALL the way in. I hear this part is no longer available? How about the internals? O ring? Valve? I could always hone the cylinder and valve but don't think that will help the oil pressure!

Should I start looking for a good used one or just shim this one and go?

Also thought some would like to see the PO ghetto fab on the oil lines to the filter. I was scared at first thinking the idiot had restricted the oil flow but after looking into the filter housing and seeing the tiny 3/32 hole I was no longer concerned. I am replacing these anyway as they are too short to properly clear the headers.

Oil pressure regulator

That is an interesting Micky Mouse job on the oil lines. It must have been done a long time ago before BSP fittings were available . .

The pressure valve just opens up to regulate the oil pressure but I thought that was on the oil pump. It isn't a bypass valve in case the filter gets plugged, is it? At any rate, I wouldn't trip on it, based on its appearance. Shimming it would be a trial & error thing. Getting all the gowlau out of it probably was all it needed.

I think a true ghetto-fab would involve some JB Weld and/or Duct Tape

That amount of scoring will not let enough oil slip by to worry about. Before worrying about the fact that it is adjusted all the way in... what were your pressure readings?

If that spring is trashed (doubtful), then you can just replace the spring. Or shim it (so long as you do not wind up bottoming it out and preventing he valve from opening.

If you are rebuilding a tired motor, then the regulator may have been adjusted all the way in, due to an attempt to keep pressure up. With fresh bearings, you may find that you have to back it out anyway.

BTW, don't be tempted to increase the flow to the filter. If you do, you reduce the flow to the bearings.

Well I'm bringing this thread up again as I'm now putting the engine back together after painting some things.

While reassembling the regulator I found the O-ring shown in the first pic has a crack in it and must be replaced.

It is hard as a rock and does not appear to be just rubber but some harder compound. I'm researching O-ring materials but thought someone may have an idea as to the material I should replace it with? I'm not a materials engineer. It will have to withstand engine oil temps and pressures. Of course if someone should have this o-ring just lying around feel free to speak up?

Mark, the oil pressure was in the 40 PSI range but the mechanical gauge that was installed was questionable. This engine has sat for several years with an occasional start so the mileage is probably 100-130K tops. (Odometer no worky) No smoke and plugs look good. While I have the pan off should I look into the oil pump? I have no intention of messing with the oil flow at all. I may even re-use the ghetto oil lines!

I have a complete 1976 2F engine/t-case-tranny sitting on a trailer ready to drop in if I need too!
