Oil priming
Oil priming
When I prime my engine should I expect to see oil coming from each pushrod? I'm only seeing it from a few. I searched before posting but learned mostly about frogs eating the moon for some reason.
Re: Oil priming
Yes , All of the pushrods should have oil coming from them if you run the primer long enough . I'm not sure what your using to turn your oil pump but the last time I primed an engine using the modified distributor turned by an electric drill method it took almost 3 minutes for all of em to be showing a healthy oil flow .

Re: Oil priming
You may have to turn the motor over a little at a time to get all of them to have oil come out.

Re: Oil priming
Well since priming doesn't actually accomplish anything except make you feel better about your work anyway, might as well start it up and see if oil comes out while it's running.

Re: Oil priming
Not much to elaborate... I completely agree with this, except for the "see if oil comes out" part, because IT WILL. It always does if the engine is assembled properly. Even that, is a waste of time.
Do the job right, and there's nothing to worry about.
"Priming" is a placebo for the insecure.

Re: Oil priming
Priming also serves to 'wash' out any assembly lube that may have been applied to bearing surfaces.

Re: Oil priming
if you use a good assembly lube, 99% of the time there is no need to prime.
but priming takes just a few minutes, pulling the motor or trans just to replace a bad galley plug takes hours. i hate pulling a motor out that i just put in because of an oil leak that could have been found on the stand.
for that & a couple of other reasons, i always prime.

just a few minutes
Gallery plugs don't "go bad".
Best idea is, look at all the holes before you button it up; then you don't have to fiddle around with a bunch of Charlie Brown's "blankie".

Linus had the blanket. But he didn't prime fresh startups either.

Re: Oil priming
true, galley plugs don't "go" bad, but they sure can "be" bad right out of the package. worse yet is when an orificed plug is put in a rear passage & then painted over. yeah, makes a nice stream of oil, right on the flywheel.
besides a bad galley plug or 2, i've seen the block cracked where the plugs go. my guess who ever put the plugs in wasn't having a good day.
had a couple of motors that the assembler left the front plugs under the timing chain out. i knew something was wrong because the feed back from the drill wasn't right.
pulling the timing cover on the stand is a lot quicker & easier than pulling it in the car, at least with my back it is.
problems like these are why i have always preferred building the motor myself, but in a normal shop environment that is seldom possible.
those are a few problems i've seen and were mostly from different builders.
over the years i have put in a lot of motors.
the few minutes of priming on the stand i've done has probably saved me more time than it wasted.
something else i do that many have told me is a waste of time, checking the torque on the rods & mains, even if that means pulling the pan. the waste of time is when i didn't do it & i needed to.
i probably do a lot of other things that most consider a waste of time.
