Runs pretty good but no oil pressure

Iwannagofast · March 7th, 2009, 12:06 AM

ok so i had the thread about the pcv valve problem and such well i replaced that and replace the coil wire and it runs and idles pretty good....idk if im gettin full power because idk how fast it should be with the new stuff

my main problem is NO OIL PRESSURE unless i rev it pretty good

i havent plugged the smog holes on the heads yet...could this be the reason?

also i got coolant in the oil but i started it up to make sure it was all flushed down and then changed it but the oil looked like coffee with creamer in it and kinda lumpy.....

i also changed the oil again tonight and it was already black

but any ideas on the oil pressure....could i have just messed up the sensor somehow....how can i tell if i have oil pressure other than the guage

Well if u got coolant in oil then that will have an effect on oil pressure.. Not sealed right somewhere...

do u use the stock guage... get a mechanincal gauge in there and make sure it isnt the stock guage thats bad

the coolant was in there because i was doing the intake swap and it fell in there when i took the old intake out....

that doesnt mean there isnt something wrong with it.. but your right that probably isnt whats wrong

My stock gauge has never worked properly.. you can put a mechanical one on temporarily to see if thats your problem.. the oil pressure port is right by your oil filter. The stock sending unit is there.. it is a round cylinder looking thing about 1" diameter and about 2" long, with a wire plugged on top of it.

I have a nice "tool," its a mechanical oil pressure gauge on the end of a 2 foot long hose. It just screws into the oil port so you can check what oil pressure you have, without going through the trouble of running a line and mounting up a mechanical gauge.

..The smog port holes wont affect oil pressure, but they need to be plugged.

ok so hopefully the smog holes being plugged will give me a lil extra go to be where i was expecting

You mixed coolant and oil and put it back in the car after the intake swap?

I think he means when he took the intake off, some coolant went down into the oil. Sounds to me like he has drained the oil twice since that happened.

It would have been better if he didn't run it at all with the coolant in the oil, and drained the oil right after he replaced the intake instead. Remember, water is heavier than oil, so the water immediately went to the bottom of the oil pan, where the oil pump pickup is.

Running it with that coolant in there even for a few seconds pumped the coolant thru the oil pump, the oil galleys in the block, the heads, the crank, all the bearings, everything. Not good...

yeah im regretting that.....damnit i just wanna drive it.....this is bs

GoodOleBoyzRacin · March 7th, 2009, 11:17 PM

any oil pressure at all? if i remember stock pump 15-25psi at IDLE is normal. it should be 50psi atleast anywhere else.

Iwannagofast · March 7th, 2009, 11:58 PM

im about to upload a video of what the gauge is doin....gonna start a new thread cus i figure most people have stopped lookin at this one

Notcho · March 8th, 2009, 04:00 AM

They say that you want 10 PSI oil pressure minimum for every 1000 RPM...

A stock gauge doesn't tell you accurate oil PSI. The main idea of the stock gauge is to show you change in oil pressure. If it ALWAYS stays at a certain point, then all of a sudden it shows nothing, you may have a problem. If you want an accurate reading, get a mechanical gauge.

the coolant fell into the lifter valley when i pulled out the old intake

Smirnoff · March 9th, 2009, 06:42 PM

how long have you been running it with water in the oil?

Iwannagofast · March 9th, 2009, 07:36 PM

i just started it and pulled it on ramps.....it made it pretty chunky so im thinkin that chunky part is clogging something....cus if i rev i can get some pressure
