my project spawning project is close to a near end, i got the intake and carb and everything back on, i start her up with the drivers side valve cover off. barely any oil was coming out.

now my neighbor said that the oil pump could have taken a crap ( which may have caused the collapsed lifter in the first place).

another thing is he said some distributors have a rod that goes in to the oil pump, he said it may have come out or it may have not been sitting right..

do the 305s have that rod?

and can anyone else either give me another idea of what may be wrong, or if one of the two possible scenarios i was told is more likely?

i hope someone can help me, this is driving me crazy

As long as oil is coming up, you're probably fine. It's been my experience that some engines like to shoot oil all over while some just dribble. Too much oil to the top is a problem too.

Your 305 does indeed have the rod that you mentioned. The distributor drives it, which in turn drives your oil pump. Did you line it up to seat correctly with the distributor when you reinstalled it?

Make sure it's correctly joined to the distributor before running it again.

well only 2 of the rockers were getting a little oil dribbling out.
the others were bone dry.
does the car sitting for a month have a play in it?

and Quick_Trans_Am, i was not aware of this rod, is it visible? or do i have to look into it?

If the engine has oil pressure then the pump is working.

Oil to the rockers is more for cooling than lubrication. As mentioned above, not all will squirt lots of oil. If in doubt, put the rocker cover back on and drive around the block a few times then recheck.

If you have a collapsed lifter, you're probably going to need a new cam and lifters anyway.

My race engine has oil restrictors to limit how much oil goes into the cam gallery which eventually gets to the rockers. Using roller lifters and roller rockers, I don't need as much oil. When I pull my rocker covers off, there's always oil on top of the heads.

hmm so then i should be good?

should i take off the distributor and check the rod anyways?

would an oil change be a good choice to do as well?

oh btw, sort of off topic, i found out what could have been draining my battery! the oil pressure sending unit. i'll def try to get it done this weekend.

The oil pump drive shaft is attached to the oil pump with a plastic sleeve. It goes in from the bottom and engages into the slot at the bottom of the distributor. The camshaft turns the distributor, the distributor turns the oil pump through the pump shaft. If you have any kind of oil pressure then the pump is turning.

I fabricated a primer to prelube the engine during assembly.

Get an old HEI distributor. Strip everything off the top until you have just a shaft and the body. Grind the teeth off the gear. This can be dropped into the distributor hole. It fill block off the cam gallery like a regular distributor and engage into the oil pump drive. With the teeth ground off the gear, it won't make contact with the camshaft. Attach a drill onto the shaft and spin it. Instant oil pressure will fill every gallery in the engine. It won't pump oil up the pushrods because the lifters are not pumping up but every bearing will get oil and with a gauge, you can see how much oil pressure the pump is making. If you get over 50 psi pressure, you'll probably need to use a 1/2" drill to keep it turning.

Oil pressure sending unit should be a single wire. This is a ground circuit providing a variable resistance to ground. Broken wire, no pressure on the gauge. Wire connects directly to ground, max oil pressure on the gauge. It shouldn't drain the battery.
