Straight Six No Oil Preessure

i think they mean the plugs at the ends of the lifter bores, some engines have like mini freeze plug type and some have thread in 1/8"npt pipe plugs. maybe the pump shaft is out or the pick up screen???

you should be able to hear a lot of oil moving inside if there's a plug missing

not familiar with the internals on that one but yeah it happens. long time ago a bud left a plug or 2 out of a small mopar, had some pressure cold but no pressure as the temp came up. between a couple guys that worked on it they were sure the plugs were missing, after they got them in the motor was fine except for being a small mope LOL

another, big mope, the lazy machinist supplied std bearings on an undersize ground crank. same deal, some pressure cold falling away as temp came up. swapped bearings & it's still running 20 years later

Does anyone here have any experience on the 170-200 sixes?

The Falcon wagon I just bought has a rebuilt six in it. Got a bit more of the story - the last owner and his buddy tried starting it, ran but no oil pressure. His buddy suggested that whoever built the engine may have left a "plug" out from the timing chain area and that was probably the issue. Anyone ever heard of that? Engine is obviously a rebuild that has not seen any use and has been sitting a long time. Oil looks new, everything looks fine. Thought about pulling the distributor and seeing if I could get some pressure built up with a drill. The guys said they only ran it for a short period and shut it off when pressure didn't come up. Looks like it had never been cranked before they tried it. Any suggestions before I yank it out? Whoever built it installed a brand new fuel pump, carb, distributor, coil, filler caps, filters, etc.

May not keep it in here, but a rebuilt six does have it's own appeal and I would like to hear it run before pulling if I decide to go the V8 route.

1) "plug" left out?
2) oil pump lost it's prime from sitting?
3) bad oil pump?

	Going to try the drill first. If nothing, then I'll pull it out. Thanks guys.

	From what I was told, the pressure never came up. I had not heard of a plug by the timing cover. I know some engines have oil ports that are plugged to slow or speed drainback to the pan - whichever is needed - but this one is news to me.

	i worked on lots of falcon 170's way back in the day. i'd try the drill thing and maybe remove the valve cover or something to see if any oil is flowing
