Oil change Fiasco! Emergency!
 

Yes, I'm dumb enough to screw up an oil change.

So, start the car, no oil pressure, and I hear a squirting noise. I shut the car off and see oil gushing from the oil filter housing. Stupid me forgot to replace the o-ring, and so I went to remove the lid, and it wouldn't budge. I jammed, pulled, done everything I can possibly think of and it won't budge.

Any ideas? I talked to my indy and he can't do anything for me until Monday.

Tap it up/off with a rubber mallet or screw driver handle???

I don't understand - the nuts come off, but the cap won't pull up when you tug on it?

I've had a hard time pulling the cap off before due to either suction from a seal with the oil inside, or just because of the weight of the oil in the filter... but usually a good pull with my fingers prying up around the rim of the lid will do it.

Maybe there is more oil than usual in there, or a sort of seal formed with the rim due to the lack of o ring causing a vacuum making it hard to pull off. :confused:

Yes, pulling with all my might. Prying with various devices, chiseling with a flat screw driver and hammer... No dice. I'm infuriated.

Start it up. Pressure should push it off. Cover it with a big rag or towel. Can't make that much more of a mess than you already have.

Rubber mallet

Highly doubtful that the oil pump can exert more force than I can, plus with the amount of oil leaking out, I seriously doubt its creating any kind of pressure to push up on it.

Rubber mallet where? Has nobody ever had this problem?

Hey Tyler, you have a knack for baptizing every diesel with engine oil don't ya ? :D

Try loosening the 2 nuts to where they cover the stud threads, then tap on the nuts with a hammer. If that doesn't work, tap all around the side of the cover. Without the o-ring, you may have wedged the cover into the housing.

The old o-ring should still be there. I'll give it a shot.

If it doesn't work, try to hook an edge of the cover with a short flat blade screwdriver and tap screwdriver with hammer.

Sounds like something is bent or jammed. I'd let your indy look at it, if you keep hammering it your probably going to need a new lid. They are just cas aluminum, ie they don't bend they crack.

Maybe without the O ring the shaft went in a bit to deep and got stuck?

hammer a flat head screw driver in the side from alternating angles

I don't know about that....100 plus PSI of pressire times how many square inches for that lid. That is a lot of force!

I run the car for 5 seconds, and it creates a 5 square foot puddle of oil. I'm not going to start it again.

Tried the hammer and screw driver... I can only get to about a third of the housing with all the obstructions. It bends, but doesn't move.

No doubt I've ruined the lid by now, the entire motor was moving from the force I was exerting on it.

He did say oil was gushing out and no oil pressure.
