oil pump

[jizake1jz]

anyway to check if the oil pump is bad vs something else causing oil to not circulate?

if the oil pump is bad on my 1j, can i purchase a new one anywhere? or are there just parts that go bad that can be replaced?

did you change anything associated with the pump? for example did you change or take off the oil pans?

turn the crank, and see if you get oil pumping.........



If you need a replacement, I'm 99% certain a 2JZ-GTE pump is identical.

You just like doing that to me today don't you :eek3dance

haha its a good thing no worries

yeah i checked on this earlier right after i posted. its definately not pumping oil. can anyone confirm that the 2j pump is identical.

an as far as removing the pump, can this be done in the car or does the oil pan need to be pulled off?

 

[jizake1jz]

here is the oil pump that driftmotion sells as a stock replacement for the 1jz/2jz. it looks the same as the pump currently on my car:

here is a pump that titan motorsports sells as a 2jz replacement, but it looks different. is one of these pictures the wrong picture? i doesn't look like the one below would be right for a 2jz...

titan gives the part number as 15100-46052. i need to ask driftmotion what the part number to see if its the same. just want to make sure i but the right part when i buy one.


Or can i just buy parts for the 2jz pump to rebuild the one i have? can an oil pump even be rebuilt?

 

[tlo86]

can always take it off and reseal it. replace the o rings and gasket in the pan as they do go bad an might be the reason you are getting no pressure.

i dont know what the one on the bottom is for, maybe its the backside?
you can always buy the pump from toyota. kaizen rebuilds them as well IIRC

Read up on the procedure for checking oil pump clearances.

If it's not pumping oil, don't worry too much. It may just not be primed,

 

[jizake1jz]

if you crank the motor over, doesn't that prime it?

 

[di_rosa]

you have to crank the engine over for almost 10 seconds before your oil pressure gauge will read anything, and if you do it by hand, you won't see any oil pressure.

like stated above, only real way to tell if the oil pump is good is to rip it out, open it up, and check the three clearances with feeler gauges. or you just gamble with it being ok. most of the time, if when you pull the pan off, and there's no metal in the oil, you should be good.

 

[jizake1jz]

no i cranked it over more than once for over 10 sec. and i have an external oil cooler (aka the reason for my problem) and i have the line disconnected to see if oil would come out. no go.

i drove the car around the bock as well. shitty. i hope everything is still ok.

so if the clearances are off, it won't make any oil pressure?

 

[di_rosa]

they'd have to be really loose to not make any oil pressure at all. i've blown 5 2jz's, and the oil pumps i've used even though it was blown, it was still running about 0.4bar of oil pressure at idle, and when i ripped apart the oil pump, my clearances were wayyyy out of spec. but i still had oil pressure, so yeah, you'd have to be wayyyyy loose to not make any.

if you missed the o-ring on the oil pan when putting it back together, you'll loose most your oil pressure through there. then there's that metal gasket for the pickup you could be loosing oil from.

i don't know about that oil cooler, maybe it's hooked up backwards? i'd probably try ripping that off and making sure you can build oil pressure. if so, then it's your oil cooler setup. if not, somethings wrong, and you gotta pull the engine

 

[jizake1jz]

if it was backwards, would that have have caused the pump to go? i never took the motor apart so i know its not the o ring or gasket.


but like i said, i have the feed line from the block to the oil filter completely off and nothing comes out.


what i had just blocked off the line, so that the pump was basically feeding into a dead end. would it break/ throw off all the clearences from the back pressure of the oil having no where to go?

 

[annoyingrob]

If the pump was feeding a dead-end, you would end up bleeding through the pressure relief valve in the pump, and it would just drain back into the pan.

Cranking by hand won't necessarily prime the pump. You need a fairly quick pumping action to overcome gravity, and get the oil up through the pick-up. This is why it's recommended to prime the pump with the starter, with the EFI fuse pulled.

was thinking the oil pan thing too

how do you know you are not getting oil pressure? stock gauge or aftermarket?

 

[di_rosa]

my stock gauge wouldn't read any oil pressure when i primed it with the starter method, but my greddy gauge did, so keep that in mind. stock gauges are wayyyy too slow.

though i thought he said he had the lines open and was waiting to see oil come out? i had a crap load of oil coming out of my turbo feed line when i primed the engine, so if he doesn't have oil coming off the oil filter housing, somethings wrong.

try pulling off the oil cooler setup completely and going back to stock and see if you have oil pressure.

and i didn't mean take the engine completely apart, i just meant changing oil pans, because there is a stupid little o-ring there, along with a metal gasket for the pickup.

kind of wonder how many people actually changed those hehe i did

 

[annoyingrob]

^ I did too.
