Does anyone have a pic or the dimensions of this part? I think i might be having oil pressure issues and just need to be sure i have the right washer installed. Thanks in advance.

It looks to be the washer for the crank gear for the timing belt, PN: 90023412700

I don't have the info, sorry.

Part diagrams dont give any dimensions from what i saw.

If the plunger at the end of the oil pressure relief valve is obstructed an unable to close fully would the make a car have no oil pressure? I had a small piece of wire lodged in between two of the four holes at the end of the OPRV that wasn't letting it close all the way.

I have a 87 944 n/a, sorry thought i had that in my signature still.

A piece of wire!?! How in the world did that get in there? You're lucky it didn't destroy something. Does the piston in the OPRV still move very freely and smoothly throughout its travel. If it is rough, or the surfaces are scoured, it should be replaced.

OPRV seems to be fine, so this would have been the cause of the no oil pressure?

HondaDustR · 10-08-2010, 07:14 AM

If it's fine and you have no oil pressure, then it's probably the big washer or something related. I wouldn't substitute any other part for the correct one, so you should order a new one or find a used one off of someone if yours is missing or damaged. I don't believe they changed it across the model years, but I could be wrong. Make sure you have a new green o-ring that gets sandwitched between the chamfer in the pump drive gear and the washer. Then it's the cam gear, then balance shaft gear, making sure the cam gear is facing the correct way (can't remember off hand what that is). If you have power steering, make sure the pulley stays seated around the end of the crank as you screw in the crank bolt/washer and not getting pinched between the end of the crank and the crank bolt washer. Also, make sure the bolt is torqued to 158 ftlb, since the pump drive gear relies solely on the tension put against it by the bolt, washer, sprockets, etc. It is not keyed or splined to the crank.

Good write up honda but would that still doesnt answer my question. Would it effect my oil pressure that much?

HondaDustR · 10-11-2010, 07:55 AM

Well, the short answer is yes. The washer can definitely affect oil pressure if it is missing or not of the correct dimensions, most likely thickness. It is roughly 2mm thickness IIRC. The oil pump drive gear will slip on the crank and not be driven enough if at all if any of the parts between it and the crank bolt are either incorrect parts or incorrectly installed. It needs the tension of the bolt torque to hold it and if the washer is too thin, the main bolt washer may bottom out on the end of the shaft before sandwitching the crank running gear against the oil pump gear hard enough.

Hate to say it but I was talking about the OPRV.

Thanks for the responses though.

HondaDustR · 10-11-2010, 02:26 PM

Well, what does the pressure do without the wire jammed into the OPRV if it otherwise looks and feels fine? If it's still the same problem, refer to the above posts about the washer and crank pulleys. It's not rocket science. The only other thing that would kill oil pressure is a cracked or broken pickup.

ace_944 · 10-12-2010, 05:52 AM

Thats just the thing I took off my oil pan thinking it was pickup so i have to wait for parts to come in before i can throw her back together and see. Ill let you know how it goes.

HondaDustR · 10-12-2010, 10:51 AM

If you have it apart waiting for parts, you should have the pickup reinforced, since it can crack.

ace_944 · 10-15-2010, 06:14 PM

Wow im pretty sure i found out what my problem was my over do everything a$$ caked the cam gasket with sealant thinking it was the right thing to do, come to find out its supposed to be dry. Guess i learned my lesson the hard way, ordering a new gasket next week ill post results and try to get a few pics up. Thanks for the help everyone.

ace_944 · 10-23-2010, 05:02 PM

I finally got it running right i forgot to install the oil pickup tube seal.

HondaDustR · 10-25-2010, 07:38 AM

Ouch! O.o ...yeah, that would do it.
