I cant get it to prime! This is the motor i got from Muley. Ive tryed spining it over with no plugs a few times. i only have a test light hooked to the sending unit. but no oil is coming up to my top end. light stays lit. any ideas? it was lying on its side for several years. i have 3 quarts of oil in it. nothing. i dont have the oil vent box on the motor or the dizzy in. valves have been adjusted. any ideas?

You might just have to invest in a cheap Harbor Freight oil pressure gauge. The fitting I believe is 12mmx 1.5. Only then you can be sure.
-
Might just be a bad oil pressure switch. Remove a valve cover and see if any oil is reaching the rockers or loosen the banjo bolt where the oil line to the heads is secured to the block and see if oil squirts out there when you crank it.
-
rockers are dry. no banjo on my ev.

Sure there is: right near the oil pressure switch, down on top of the engine case. Or just remove the oil pressure switch and see if oil squirts out there.

same here in Ct., hate it

If the pump is totally dry, it may not want to prime. I had that once, on a motor that was dry for a long time. I buttoned the motor up tight. pulled the oil pressure switch, and put a few PSI of air pressure in through the oil dipstick hole using a rag wrapped around an air line. After a time, a little oil started to ooze out the pressure switch hole. All was well after that.
-
Standard procedure on dry VW engines is to pack the pump with lithium grease for first startup. Wayne's method ought to work, too.
-
that might work if i had it apart that far.
-
Go with Wayne's then.. I think Charlie has posted he primes engines that way. Takes a while with low air pressure.
I'll see if I can find that thread..
-
cool!

I have in the past, on ones that won't prime by themselves. I drilled and tapped a drain plug for a schrader valve and screwed that in the dipstick hole. 5 psi is all it usually takes.

Thanks, Charlie.. I couldn't find that thread. :smiley:

With my luck, at some point the air line would come off of that schrader valve, it would not work right, and there would be a lot of pressurized oil everywhere. :boozing:

On the one I made, the core isn't in the schrader valve and I pressurize with a $4.99 Harbor Freight tire inflator with gauge. Haven't made a mess yet, but there's always that chance! :grin:
-
i bet my landlord would like to see the garage sprayed with oil...ill roll it out side at daylight to hot now, done hit 90...very humid!
:evil:
-
Pull the pressure switch and crank -- see if oil comes up the galley. Did you fill the filter with oil?
-
no i didnt. might drop the pan and do that. didnt think of it
-
i bet you could fill the oil system from the top too. if you had no air
-
determine if the pan gasket hasn't been installed upside down.
It's easy to do.
don't ask me how I know. :undecided:

It's no big deal.. trust me on this one.

whar he said
-
i think the gasket is instaled
correctly
-
I was wr wrr wrrrong. lol its was hot that day. and it finally cooled off. i dropped my pan and danmmit both gaskets were bass ackwards! filled my filter too. pump is ok. try sometimes this week to retime and drop my dizzy. and readjust my valves
-
been there, done that.
glad you found it.
-
And THIS is why I love the Wild Goose Chase and it's premium members! :thumb:
No point in naming y'all, wouldn't want to leave someone out !!
:bow:

remove oil pan fill filter with oil remove oil pressure switch and try to fill with oil remove plugs and crank it over pressurizing crankcase does work but do not over pressurize could push seals out.Some parts stores carry an engine oil primer you can rent for a small fee that works pretty good.
-
I would definitely stop drinking while you wrench.
-
I havent boozed in years
miss it lol :boozing:
-
At the risk of sounding very naive, how does one determine which way is upside down?

The other way doesn't match the oil holes. I hate it when that happens.

it was a 100 degree day when i put it together and i wasnt wearing my glasses. nuff said.

what RK said.

I bet the glasses for the optically challenged has something to do with it. :tongue: Sweat in the eyes while working on something will have a negative impact. :shocked: BTDT. :grin: Feel your pain. :1:

An easy way to plumb in a gauge is to attach a second banjo on top of the one that's there, drill out a longer bolt with an extra set of holes to match.
I mounted the gauge for my Eldo and the California II onto the crash-bar so it doesn't need to be flexible, plumbed with copper tube.
