Oil light on....

(Click here to view the original thread with full colors/images)

Posted by: my95mark8

Today I replaced my oil filter adapter gasket. Now my oil light comes on.
It flickers at idle, and gets brighter when the rpms go up.
After I finished working on it, I drove it about 20 minutes, no problems, but later I drove it, and the light started coming on, so I brought it home and parked it.
I changed the oil and used the same oil that I have been using, and a FL-820s oil filter. It doesn't appear to be leaking, and the oil level is fine. There are no strange noises.
I don't see how changing that gasket would affect my oil pressure. I made sure it was the correct gasket, and it seems to have gone in correctly.
I have a few theories about what might be going on here.
1) Maybe I have f'd up the wire or connector to the oil pressure sensor. It did get soaked with coolant when I was working on the gasket, I didn't bother to clean it off. Maybe there's a bad connection?
2) Maybe I somehow f'd up the oil pressure switch..
3) Maybe a defective oil filter?
Anyone have any other ideas or suggestions?
Thanks.

Filter bypass could be stuck open? I dunno...

As luck would have it, I threw out my back yesterday, and can hardly walk today. Hopefully later on in the day I'll feel well enough to go out there and look at it. What is another good brand of filter? I don't want to just grab another one that is probably from the same batch (in case that is the problem). I will probably just change it to see what happens, if I don't find any problems with the wire. I don't want to use the "orange can of death".
The filter is the only thing I can think of that would cause a change in oil pressure. Other than that all I did was take one gasket out, and replace it with another.
Should the old gasket look like the new one? I thougt that I had read that they use an updated design now. One thing about the gasket, it only leaked badly when It was cold out, at startup. I remember in the winter it leaked everyday, then when the weather got warmer, it slowed down.
Hopefully it is nothing serious, I don't want to blow my motor......

Did you disconnect the oil pressure sender harness? I did the same thing on my Gen-II and forgot to plug-in the harness. Sometimes I forget to plug it in after an oil change.

I disconnected it at the switch. I did plug it back in. The one thing that makes me think maybe it's not a pinched wire is that the light changes with my RPMs.

I was just thinking....what if coolant got in the crankcase when I took the adapter off. ALOT of coolant came out when I took it off...and I know I left the plug in, even though I had read something before that said not to. Now that I am thinking of it, I thought about taking the plug back out in case of coolant, but I know that I didn't. There is no coolant on the dipstick.

Often time, on various cars, the sensor and/or the wires to it go bad. I was always worried about it so I just put an aftermarket oil pressure line and gauge on it. Saved me many headaches. Believe it or not I have had a 5.0 that read 0 at idle and I never had any problems. Eventually I did replace the oil pump.

I think tomorrow, if my back is better I will check the wire, and clean the connection. If that doesn't work, I will change the oil. I though about swapping the filter back to the old one just to see what happens, but I picked up a new one.

Don't know. Cars are strange animals.
