Post Oil pressure light on, need opinions

Ok, I just got my oil changed. I have a B&M oil cooler so the oil filter is relocated. The oil filter I have to use now is rather large, and the guy who I bought the oil cooler from said to use a "Ford" oil filter. Anyway, everything fits, changed the oil and I fired the car up. Everything is fine up to this point. So I shut the car off, clean up the old oil and prepare to go the dumping station. I start the car, drive off, then before half a block away from my house the oil pressure warning light came on. Went home, checked the oil drain plug, fine no leak there. Checked the oil filter, thought it was on tight (it is) but anyway, there appears to be a small leak there. That's probably my problem.

Question now is, do I have to get a new oil filter and basically do another oil change? Or is there something more serious? Most importantly, can I still drive my car? I will probably take it to my dealer or somewhere and take off the oil cooler.

You need to know what the right filter is. There are a lot of "Ford" filters. Also, how tight did you tighten it? If you overtighten the filter it might get bent out of shape and not make a good seal... doesn't sound plausible, but maybe.

That's what I was wondering too when he said that. Anyway, it's a HUGE filter.

And I think I might have overtightened it..I kinda went overboard cause its mounted funny so I didn't want a leak. Sucks...thing is I DO have a leak, and it probably is because I overtightened it.

I can just change the filter right? And then add more oil to top up?

The "Ford" filter can hold a quart of oil. Add in the extra hoses and the cooler itself, that adds up to another 1/2 quart. When you changed your oil, I hope that you put in 5 1/2 quarts, maybe more.

Double check your oil level. Remember, oil filters should be hand tight. Do not use a filter wrench to tighten a filter. Pre oil the gasket on the new filter before installing. This will help to seal and makes it easier to remove for the next oil change.

Later, ARG

That much oil?? A whole quart??

I put in 4 and a half bottles of Royal Purple.

I'm pretty sure I did crank the oil filter too hard though. Oh yea, I always use my hands...

But inorder for the oil light to go on it must register a few psi of oil pressure to go on. A little drip shouldn't turn on the light. I am sure when the oil light goes on on a car, the car have almost run completely empty. Kent I think you might have a faulty oil sending unit.

I have the same oil cooler as you and it also came with a gigantic "domestic" oil filter. I didn't use it. I still use Subaru oil filters on my oil cooler. I also did not use those huge oil lines that came with the kit. I had stainles steel lines made instead. I have not had any problems with an oil light. I have to add another quart (total of 5) when doing oil changes.

I would say ARG is right...

Chances are the oil stat open to the cooler....which was empty.... when you fit an oil cooler or do an oil change, you always pre-fill them first... pour oil into the oil filter.

Otherwise you could ruin your engine!

The reason they use "domestic" filters is due to the thread type... not being metric link the Subies.

ARG - which Subaru oil filter do you use? Cause the mechanic at the dealer that installed mine said that the Impreza oem filter won't fit the oil cooler.

I think I'll go add the extra half quart I have left.

I haven't had a chance to change my oil yet and I don't have my manual with me. How much oil are you supposed to put in there during a oil change 4 or 5 Quarts?

The oil sending unit is the sensor that turns on your oil light when there is not enough oil pressure.
