Does anyone have pictures of an h22 oil pump install and should I pull the motor or leave it in which route would be easiest?

 

Ugh you are going to have to remove the upper and lower timing cover, timing and balance shaft belts, harmonic balancer, oil pan, auto tensioner etc. Ive done them both in and out, I prefer with the motor out but have never taken the motor out just to replace the pump.

 

if it was me i would pull the engine. it would be a pain in the a$$ in the car but i can be done.

 

Dl the service manual. http://www.spoonhonda.com . I can't imagine why it'd be difficult to remove the oil pump with the engine in the car.

 

it can be done with the engine in the car there just isnt much room in there.

 

Well, you remove all the stuff out of the way including the balancer shaft pulleys. After that unbolt the oil pump bolts and just slide it off the crank right?

 

Yes, just easier if you don't have to work around everything. Whats the reason for replacing the pump? Just preventative maintenance or did something go wrong?

 

I just put together my h22 and its not getting any oil.

 

gL with all that.

I would pull the oil pan off first and check the oil pick up thing and inspect that first for clogs.

Besides that the crank pulley bolt will be the hardest thing to get off without proper tools. So heads up on that.

Did you ever get in touch with the builder and find out if he used new or used parts for your build?

 

Ahh why didnt you say so? Did you prime it? The pump really isnt going to quit working unless something breaks in it, but then you'd have other problems. If the motor is new I would say it needs primed or maybe the pickup is hitting the bottom of the pan. Dented pan maybe?

Try removing the large allen bolt at the rear of the oil pump and pouring oil in there to get it going, if its dry in the pump its not going to be able to pull oil out of the pan on its own. Put some oil in there, put the plug back in and give it another shot, I bet that will take care of it.

 

I've had an oil pump that partially failed. It was producing pressure, but not enough. It was right after a build, too. 15psi@3000rpm.

It could happen, by chance was yours primed? There are just two steel gears in there in the aluminum casing, if the gears arent actually broke then the aluminum casing is probably worn so that its no able to make pressure. I imagine that if the oil pump was dry when installed on the new motor the steel gears would gall on the aluminum casing and it would tear itself up, then when the oil finally did get up into it it wouldnt be able to hold any kind of pressure.

 

i doubt this thing was primed but are you sure it needs primed first and it wont pull oil unprimed

 

The priming didn't work. It just let the oil drain right into the pan, so im not sure what to do now.

 

you are priming the engine so everything is lubricated upon startup and to be sure that the engine builds oil pressure. if it doesnt build pressure and you start the engine, it will be toasted in a matter of minutes.

you arent giving us enough details, but i would inspect the oil pickup.

 

I pulled the oil pan off, I inspected the oil pickup and there is no clogs anywhere. This is really driving me crazy because i cannot figure it out. What other information do you need to help me out.

 

I was told that the oil gally may not be plugged. Would this cause my problem? And if so does anyone have a picture of what I should be looking for?

 

Well I just pulled the oil pan off and it appeared that the pickup gasket may have had a small leak. I put a better gasket on it and some grey RTV. Hope this does the trick

 

Ok here is an update. The RTV didn't solve the problem, I filled a bottle with oil and submerged the pickup into the bottle. I cranked the engine for about 30 seconds and it didn't pull any oil. Is this a sign of a bad oil pump or something stupid im missing although it seems like I checked everything?

 

Hmmmn I'm stumped, maybe you just need to pull the pump off and check it out. I really can't think of anything else you can do if you are sure its being primed.

 

Well the thing is I know its not getting a prime, when I try to prime it like you explained the oil just falls back into the pan.

 

when the engine stops rotating, the oil is supposed to fall back down to the pan.

 

So I guess there is a bad gasket somewhere?

 

we cant give you any definite answers. If there is oil falling back into the oil pan, i dont understand what problem you are having as that means the oil pickup has pressure to suck up the oil which means the pump is providing pressure. The oil doesnt stay pressurized once the oil pump stops spinning, it falls back to the oil pan.

How are you determining that you arent getting oil pressure? Do you have a gauge?

 

Yes I have a gauge but I took my oil pan off and submerged the pickup in oil and cranked the engine. None of the oil was sucked through the pickup.
