i was woundering how do you prime the oil pump and turbo?

i have a s13 with a sr red top

statik · 12-12-2007, 09:37 AM

Disconnect the CAS so the coils/injectors won't fire and crank the motor over until the oil PSI light turns off, if it's a fresh swap with no oil in it you should take a break from cranking every 10 sec as to not burn out the starter, it can sometimes take a good 20-30 sec of cranking to turn the light off.

UNISA JECS · 12-12-2007, 09:47 AM

what he saiid^^^and most importantly take all your spark plugs out, the cylinder pressures while cranking can destroy your bearing when there is no oil pressure present.

nine3240sx · 12-12-2007, 12:14 PM

so does the pump work off from the crank?

tknbkthrsdy4anfg · 12-12-2007, 12:18 PM

yes, the oil pump is driven by the crank in the front cover.

nine3240sx · 12-12-2007, 12:29 PM

im having a hard @$$ time trying to primp the pump.i took all my plugs and dissconected the injectors and the oil light still hasnt turned off

INeedNewTires · 12-12-2007, 12:51 PM

on the same topic (not trying to thread jack just dont want to start a new thread) if my car is running fine, primed and what not, but i install an oil cooler, how will i go about priming that thing? same process? but i dont want to pull the spark plugs if i dont have to....

UNISA JECS · 12-12-2007, 01:07 PM

I would also fill my oil filter with enough oil just to absorb into the filtering element but not so much that it spills out when screwing it on, and I would get a funnel with a small nozzle and pour oil directly into the oil filter bracket/stud to ensure the oil pump gear are submerged in oil to help get the siphoning effect going to the pump so it can start picking up from the oil pan.

nine3240sx · 12-12-2007, 06:50 PM

well i tried to prime the oil pump and no dice.i read on heavythrottle.com to pour oil through the turbo line on the block and it would help but still no dice.is there any other way to prime the oil pump?

nissan240sxkid · 12-12-2007, 06:58 PM

is this a new pump or are you starting your motor for the first time from doing a swap?

nine3240sx · 12-12-2007, 07:03 PM

this is a fresh swap for my car.i bought the motor with a slight rod knock and got that fixed.the motor startes fine but when i first started it the light kept blinking.today i took my valve cover off and my cams were dry im not getting any oil to come out of the little lines that site on top of the cams

unicoladron · 12-12-2007, 07:09 PM

are you using an OEM steel oilpan? before swapping the engine in (did you do the swap yourself?) did you ensure the oil pan wasn't dented in? this is a common problem on SR's since the engine when pulled rests on the oilpan. i say pull your lower steel oilpan off and bang the dents out with a hammer. sounds like your oil pickup isn't distributing the oil to the rest of the engine. i would stop cranking the engine until you confirm your pickup is getting oil to your engine....

wonkuuzenki · 12-12-2007, 07:09 PM

OH SHIT.
Just had to say that.

nissan240sxkid · 12-12-2007, 07:10 PM

was the block cleaned before it was put back together

nine3240sx · 12-12-2007, 07:22 PM

my oil pan isnt dented up.i did the swap my self and before i put it back together i cleaned the motor and made shue nothing was left behind.the only thing i did was weld my pickup tube bacause ive heard that red top sr pick up tubes are weak.

nissan240sxkid · 12-12-2007, 07:26 PM

Its critical that its in the exact place from the factory so it picks up oil properly. If you welded it you could of tweaked it fro heat and the flange might be suckin air

nine3240sx · 12-12-2007, 07:31 PM

well i geuss ill look at me pick up tube tommarrow and see if thers any holes in it

unicoladron · 12-12-2007, 07:32 PM

which method of welding did you use?

when i was priming my engine for first time startup, i primed it until i saw lots of oil squirting out of the squirters for the cams. basically what i did was uncap the oil filler on the vc, and cranked until oil spewed out of there. it took about 3 separate 10 second cranking intervals to satisfy this.

try cranking the engine with the oil filler off, and see if oil starts shooting the cam lobes or shooting out of the filler hole. this will determine if your pump is providing oil.

also i don't know if the OE oil pressure "sensor" is prone to failure, but did you ever think your oil light could be accurate. from what i understand it's a very basic switch.

if you're really crazy, you can temporarily connect a real oil pressure sensor to your oil filter block.

nine3240sx · 12-12-2007, 07:45 PM

thats the problem i saw no oil coming out of the oil squirters for the cams

gotta240 · 12-13-2007, 01:21 AM

Think about it... What caused the rod knock in the first place?

Did you replace the oil pump?

nine3240sx · 12-13-2007, 07:21 AM

i bought the motor with the rod knock as is

punxva · 12-13-2007, 07:36 AM

yes we understand that, but did you actually replace the pump? if not then what he's saying is thats probably why it knocked

nine3240sx · 12-13-2007, 07:51 AM

ok i never replaced the pump maybe that my problem

punxva · 12-13-2007, 07:56 AM

i'd put my money on that

gotta240 · 12-13-2007, 08:37 AM

ding ding ding. Punxva wins

nine3240sx · 12-13-2007, 08:47 AM

just wanting to know if my oil pick up tube has a hole in it can that cause my oil problem also?

statik · 12-13-2007, 08:57 AM

If your system isn't building pressure then its either the pump, the pickup, or some sort of clog, and as pointed out, since you bought the motor with knock its possible the oil pump died. I would also imagine if your pickup had a hole in it that it would have trouble building pressure as well.

nine3240sx · 12-13-2007, 09:32 AM

cool thanks ill probably look at my pickup tube today

gotta240 · 12-13-2007, 03:58 PM

Try sucking through a good straw. Remove straw.

Now punch a hole in the side of the straw. Re-insert straw into liquid. Suck.

I just helped you answer your own question.

nine3240sx · 12-14-2007, 09:31 AM

i wanted to know if its a must to take the head to put a new ol pump on the sr?or can i get away with just sliding it out?
