oiled head

caniborrow50cnts · 07-11-2007, 12:02 AM

i am not getting any oil on my head. I finally finished my 6 bolt swap. I started the motor after priming the engine. Oil doesnt make it from the pump to the head. I purchased all the 6 bolt parts to make it work in my 97 gsx. the oil is filling the filter and front case, its just not making it to the head oil ports. it has plenty of oil. what would the likely scenerios be?

guess it is too late for me to put this in the problem diagnosis thread...

It really sounds like the pump isn't working to it's full capacity. Sounds like it's not pumping it through. Is it new?

the head and block are fully rebuilt, the front case and pump are supposed to be new, but they are probably rebuilt as well. everything on this motor has 0 miles on it. I put an impact wrench on the pulley also, spun it to about 500 rpm, still doesn't flow through. both balance shafts were removed though, but that shouldn't make a difference.

Did you make sure the head gasket had the correct oil flow ports in it before installing it? I'm sure you did, but you never know.

i hope it was installed correctly, a business built it for me, but with all the issues I have been having, i wouldnt doubt it. the oil drops down from the head into the pan. im going to try and blow air through the holes to make sure it is passing through. anyone have any tips or advice for fixing the pump?

Replace? Best I can think of.

Did you get in touch with the shop that built it?

Remember though, you need to test the ports from which the oil pump send oil up to the head.

working on it, i will post updates on it. its just here in florida, it rains every day. so i just have to wait til its dry so it doesnt get water all in it and rusts

alright, so i get a day off when its not raining. I pulled the front case off, also took the oil pump out. It appears the clearance is within specs. I took an air compressor to force air through the system, in the direction it is supposed to go.

I pumped 140psi ofair in the hole with the arrow and blocked that hole with an X. From what I found, air is flowing through to the pistons, and I can feel air all around here.

As you can see though, the head is still dry, except for the original oil fill that remains. I cannot feel any air flowing, nor does any air make it here.

Anyone have any idea how the oil cant reach the head or how 140psi air doesnt either? Would this have anything to do with the head gasket and is there a possibility of putting it on backwards? Where are the holes located that the oil is supposed to be flowing through in the head?

Did you use the same lifters or different ones? If you got new ones then they need to be primed before you can use them... In case that step got skipped... If they aren't new, then I would say your problem lies more so in the oil pump/front case...

caniborrow50cnts · 08-09-2007, 07:03 PM

every moving part is new; new lifters, springs, pistons, and oil pump. I cant think of any other way to prime. how else would you do it? the block appears to be getting plenty of oil.

Blackcrow64 · 08-09-2007, 08:07 PM

You submerge the lifters in... I believe we used kerosene? And you have to use a paperclip and stick it in the end of them and then pump them up while submerged and holding the paperclip in until all the air is out of them. If not, when you start the car up then they will go flat and fail to support oil to your cams and such... I'm pretty sure it was kerosene we used.

Take your head off and look at the head gasket like I said earlier. They could have put the wrong gasket on with different oil ports. you need to see if the air is making it through the gasket.

caniborrow50cnts · 08-13-2007, 12:06 AM

after taking off the cams, I can tell some oil had flowed through to soak the braces. apparently I didnt prime them good enough with 5w-30 oil. took out the lifters again, I can still compress easily with my hand. I'll try the kerosene. also I did some research on the head gasket, before I venture on an 8 hour job with it, I don't see how the wrong one could have been put on, and from the design, it cannot be put on backwards or upside down. unless one had been cut out or customized. right now I am working on putting the oil pan back on so more air could be forced to the top. sucks working on a car when you dont have a garage though, living in florida, it rains every other day in the summer, if it doesnt rain, its 99 outside.
