I recently just swaped a JDM H22A into my BB1. I did all the recommend items when doing a swap. New oil pump, water pump, timing belt, and balancing belt. Also, for kicks i got new clutch and flywheel.

But after 1 week of trying to figure out my problems with the NO oil pressure i'm run out of options. I've searched for every possible topic on H-T about oil pressure, this is what i've tried:

-change oil sender with working one
-used mechanical gauge to measure oil pressure
-took the pan off and looked at the oil pick up
-changed all the seals and gaskets with new ones
-gave a quick check on the bearings
*no metal shavings in the oil pan

I've asked some friends that are Mechanics and they are stumped I was wondering if anyone can help me out here. I've come to a dead end. Is there something else that i should/over look to try to figure out my problem?

Could it be that the engine is no good. And all the bearing are finished/worn out?

Please help H-T.

 

It took about 1 minute of idling for my car to build pressure after I installed a new pump.

How long have you tried running the car?

 

I didn't run the car too long...maybe like 10sec's. I didn't want to run the car is there was no pressure. But i'm willing to try. I'm getting deparate.

I've only broken in a couple motors with new pumps, and installed a new pump on my motor once, but in all the situations I primed the pump doing three, 10 second cranks with the distributor disconnected. This should get enough lubrication through the bearings to safely idle the motor for around a minute.

If I remember correctly, it took about 20-30 seconds before the pressure registered on my electrical guage.

You can take my word, or wait for another response.

 

we had the same problem with a tubo H22. Set the balance shafts correctly. line them up and u should have oil pressure. it has to do with the balance shafts!

 

Try disableng the ignition. Crank the car over until the oil light on the dash goes out usually takes over 30 secs. Just my 2cents

 

i am not sure on the H22 but on other engines it would represent bad bearings. When cranking engine you may also want to take out the spark plugs so there is no compression (friction) on the questionable bearings, this makes for a faster spinning oil pump as well. just another 2 cents....

 

make sure that the oil pick up is on tight if its on loose the gasket wont seal and it will just not be able to build pressure.

 

I had the same problem and it was my oil pick-up tube. Check the gasket also. Don't worry man, it will all work out in due time.

92TypeR I'll going to give it a shot. I really hope this works!

I'm sure 100% that the balance shafts are set correctly. But i will take a triple look. I wish a had another set of eyes looking at this with me.

This is at the point where i think its the bearings too. I think all the signs are point to the bearings now.

Yeah when i took off the pan i made sure that the pick up was on tight. I used a TQ wrench to tighten all the bolts to spec.

I really hope it works out all in time. Or i'm out an engine and a car.


Thanks for all the help guys. H-T 4Life!

 

something i picked up in school....there is a device called the oil pressure reliefe valve, its a spring loaded valve that could be clogged/disfunctional. The only function that this serves is if your pressure is too high, it will relieve it. Now, i would think that this device would be in the oil pump itself, but i dont know for sure. But look into that, that would be my best bet.


good luck

another thought... nice thinking

TodaFiend,

When i took the pump off i inspected the OPV. No clogs or difunctional. The pump was brand new. But i did give a check before i reassembled the everything back together.

 

yea, then my best bet would also have to be the bearings. i believe hondas(b series/h series) havea 0.0015 thousandth oil clearance. did you plastigauge?(that stuffs cheap and works wonders )

and if this helps...oil pressure is created by heat, not the pump itself. the pump just creates flow. maybe you need a good solid warm up first?

 

Oil pressure is dictated by bearing clearences nothing to do with heat.
when you installed the new pump did you replace the gasket between the pump and pickup.

r u get n NO oil pressure or is the oil pressure low? if it's low, then it can be bad bearing clearance on the crank. do what was said b4, check the clearance's with plastigage.
if ur get n no oil pressure at all then i would check the gauge u r using. see if the lines r crimped anywhere is its a mechanical gauge

 

well i know this sounds crazy but it's true? i had a kid bring me a prelude w/no oil pressure....during the mist of everything.he simply forgot to put the main 17mm bolt in for the oil squirters."i found it when i was taking the pan off and was going to check the clearances on mains and rods"very hard to do in car....but can be done".....after i put the bolt back in...i started it up and she was fine....sometimes we all can over look the smallest things,but it's the smallest things that can cause the biggest problems.

 

I just ran into this same problem on my LS/Vtec build up using a brand new B18C5 oil pump. We took the oil pump apart and packed it with grease to simulate oil pressure, and bingo it's been around 75 psi ever since... I found out a lot of V8 guys have been doing this for a long time on race motors that HAVE to get immediate oil pressure on new engines. Hope this helps.... I know your frustration, trust me.

 

nice suggestions everybody...
