no oil pressure?

[logan1600]

So I just did a head gasket on my l16 and didn't really mess with much else just cleaned up parts and so on I didn't take out the cam or lifters. I just put everything back together and it starts up good and seems to run great but the oil light is on and its not spitting up oil threw the oil filler cap what could he causing this? I filled the oil filter and oil pump with oil prior to Installation.

"Spitting up oil through the oil filler cap"

 

Huh?

[logan1600]

Before it would spit oil through the cap when I took it off when it was running

[banzai510(hainz)]

to do head gasket you didnt need to take the oil pump off so I would assume its still fine unless you puilled the whole front cover.

 

wire on sender?

 

put another oil filter on.

ck oil level?

"Spitting up oil through the oil filler cap"

 

Huh?

Obviously lots of blow by.

 

 

 

 

Did you put 4 quarts of oil in the engine?

 

Pull the Yellow/Black stripe oil sender wire off. Light should be off with the key turned to ON (don't start). If the oil light is ON then it's pinched and grounded somewhere.

 

Pull the coil wire off. Remove the oil pressure sender. Have someone crank the engine with the starter. Oil should pump out the oil sender hole, so be ready with a large rag. If no oil do not run engine until fixed. If oil spurts out check the sender.

[logan1600]

Yes 4 quarts. And I had to do the clutch and flywheel so I pulled the engine/trans out replaced all gaskets including timing cover gaskets I did accidentally rip off the tip of the sender wire that hooks on but replaced it I will try what mike said. But if its not that what then? Oil pump?

[datzenmike]

Disconnect the send wire and turn ignition on. The light should be off.

 

If the end was ripped off the wire may have been pulled very hard and could have a hole in the insulation touching ground. Perhaps the new plug is grounding on the side of the sender.

[logan1600]

So I pulled off e sensor no oil coming out of the hole what now? Must be oil pump right?

[datzenmike]

Need to know if we can trust the low pressure light first or is it stuck on.

This is with the engine turning with the starter? If yes than it appears that the oil pump is not pumping.

Try removing and filling the oil pump with oil. Remove the spark plugs (so it will crank faster) and crank the motor over for 30 seconds. The oil pump is self priming but a loose gasket on the pick up tube or the oil pump will allow air in.

 

If you tested the red warning light and can now trust it, the light should go out from the oil pressure made from cranking the engine over.

[logan1600]

Yes its with the engine turning with the starter I actually forgot to pull the dist car so it fired up for a second and still no oil coming thru the hole. And when wire disconnected it was off when the key was on so im sure no problem with the sender. I'm going to try putting the oil pump off my ka on and do what you suggested.

[banzai510(hainz)]

make sure oil in pump before install

[logan1600]

Filled the pump to the brim. And light is still on.

[logan1600]

I don't get it! And I have to drive this thing to work in the morning damnit haha

[datzenmike]

Did you have the oil pick up tube into the oil pan off?

[datzenmike]

Try again filling the oil pump and crank with the plugs out so it spins faster.

[logan1600]

No I never messed with the pick up tube I inspected it and there was no stuff on the screen. But I never took it off and I filled the oil pump twice and made sure it was tight and the timing was all matched up. I will try cranking it with the plugs out but I had it running with the sensor out and it didn't spit a drop of oil

[logan1600]

Should I try changing the filter?

[logan1600]

I used a fram cause they are cheap and I planned in changing the oil in like 500 miles with a Better quality filter but it was full of oil when I put it on.

[banzai510(hainz)]

I heard of a bad valve in the oil filter.

But i think the oil sender hole oil would come out as you said.

 

spun bearing

[logan1600]

What does a spun Bering mean?

[logan1600]

Google to the rescue. Haha but when I had the engine out I didn't see any damage? The engines not making any funny noises and runs great. Aside from no oil pressure

[datzenmike]

It might provide a huge oil leak that prevents pressure building but oil would have to flow past the sender hole to get to it.

 

 

A blocked oil filter should still push past the relief valve behind it in the block... having said this there's no harm is replacing a fram, that's for sure.

 

Any chance the pick up tube was bumped while moving the block around?

[logan1600]

I did bump it once when I was unloading it out of a truck but it didn't move to my knolage and was still tight

[logan1600]

If I check it what should I be looking for?

[datzenmike]

Possibly bent or cracked? The pump won't be able to suck up the oil, like a hole in a drinking straw. You can unbolt the crossmember between the torsion bars under the pan and remove it. Unbolt the idler arm and let drop down slightly out of the way. The oil pan can now likely be dropped so you can see the tube. If cracked or bent up above the oil line you'll be able to see it.
