i have a 2000 honda civic and my engine is not getting any oil to the heads.. the engine sounds like also something is rattling inside but i cant seem to figure it out i need some help.... my first prioritte is to find out why its not getting oil to the heads any ideas please let me know

Does the rattle go away after warm up, or is it constant? What is your oil pressure reading?

jfrear21

the rattle is constant... and after about 10 min's of idling the rpms start to go up and down ...

pityocamptes

Any CEL's being thrown? Have you checked your pressure with a mechanical gauge? One idea might be to pull the valve cover and run it with the cover off to see if you are getting any oil up top. Is it bone dry? If the gauge shows no pressure then it sounds like your pump with south. As far as the rpm's maybe a vac leak or bad sensor?

How do you know there is no oil getting to the head?

That's my question. My second question is, if this is true, why are you even attempting to run the engine?

jfrear21

the oil light is constant I changed oil pressure gauge changed the o ring and gasket of the oil pump changed oil pump as well i primed the oil pump before running the oil pump I took of the head cover and ran it to see if oil was spitting out u can see the cam is lubricated the oil light still won't go off I put a gauge on it and it doesn't read any pressure any ideas what it might be

You haven't figured this out after 8 months? Where did you install the gauge? Did you tee off of the sender? Did you swap that out?

jfrear21

Yeah I got another car and left the civic alone now I want to fix and get ride of it ...well I connected the oil gauge where the oil pressure switch is at by the oil filter ...

Did. You. Change/Check. The. Oil. Pressure. Sender. Unit?

Drop the pan and replace the oil pump. Problem solved.

jfrear21

I checked ad replaced the pressure sender unit I took of the cover from te heads to check of there was oil going to the heads and there is oil shooting out but has no oil pressure

Former User

Your engine just may be worn out. How many miles? Was it run low on oil?

thenext

How can it be shooting out with no pressure? Are you checking oil pressure with the motor fully reassembled or is the valve cover off?

Former User

My understanding is that the oil [edit] pump creates oil flow not oil pressure. Oil pressure is produced by the engine.

Sleepy_Red_hatch

oh you are SO going to get flammed for that typo.

and yes, basic engine knowledge, the restrictions in the oiling system create pressure, since an oil pump is simply a positive displacement pump (meaning a set cc/rev)

Former User

What typo? (Edit - whoops! Yep I meant oil pump.)

Flammed?

I didn't know the fuel pump had anything to do with the oil. With the valve cover off, the PCV system wouldn't be sealed and there wouldn't be anyway to maintain oil pressure. Are you saying it might be a good idea for him to test his rings?

Former User

My goof: fuel pump ---> oil pump

The PCV system doesn't play a role in oil pressure. It has do with having a "tight" engine (e.g., bearing free play not out of spec).

jfrear21

I have. Checked it with the valve cover on and off ..

jfrear21

Could a clogged oil filter cause it

Have you checked with a mechanical gauge yet? If you have good pressure readings then I would suspect the wiring to the sending unit. If that wire is shorting out against bare metal somewhere then it would make your oil light turn on.

I have an aftermarket gauge in my 97 w/ d16y5 and although it has an electrical sending unit it runs at 60psi cold and then in the 40's-50's when it's good and warmed up, then typically when I get 20-30 it's low on oil so then I know it's time to check that.

Former User

That would generally increase oil pressure.

You didn't answer these questions:

What engine?

jfrear21

The engine has 150k miles and have always had it running with the right amount of oil

This question has been asked at last TWICE. You have yet to answer it. Why do you only respond to the first sentence in a reply?

Edit. Actually, most of your responses have been very non-responsive.
