I changed the oil in the Thunderbird on Saturday........TWICE!! I don't know if anyone else has had this problem or not but for me it is just ranting.

Apparently, while I was snaking the new filter through "the path", the seal ring came out of it's groove after screwing the filter on. I did not notice and filled the car with oil. Then drove it off the ramps and out of the garage. Well, after stopping and turning to look out the front window, there is this like of oil leading from my car back into the garage to a large puddle on the garage floor. Now I am pissed because 2 weeks ago, I did the J-Mod and ended up with a 1/2 gallon of ATF on the floor and had to clean that up. Now I have a puddle of engine oil on the floor. So I shut it off and push the car back into the garage to find out what happened. When I unscrewed the oil filter, and started to snake it out, the seal ring fell to the ground.

Has anyone else had this problem with Motorcraft filters or did I just get a defective one? This is only the second oil change using these (I used to use Fram until I found that the Motorcraft ones were better and cheaper) and I want to keep using them.

I had one come off once, but I dont remember if it was a Motorcraft filter or not. I saw it come off before I threaded it on, so I was able to pop it back into place.

It's happened to me twice, as I was installing the Purolator Premium Plus filter. It's almost as if the crimping for the gasket/O-ring wasn't deep enough. Fortunately, this happened while 'snaking' the filter into position, and not after installation was complete.

It had to have happened while I was snaking the filter through but the ring did not fall out totally. It must have just came out of the groove on the filter enough that it did not seal. It did not fall out until I got the car back up in the air and unscrewed the filter from the block.

wow...I can't even imagine how this could happen. I've never had this happen, and I've changed a lot of oil in a lot of different Fords with impossible to reach oil filters. Try changing the oil in a pre-96 3.8 liter Taurus sometime...it's lots of fun.
Maybe I have better luck because I have wicked long skinny arms ending with little delicate computer nerd hands. :tongue:

Sounds like you got a defective filter. I've had 6 Ford vehicles and used Motorcraft filters on all of them without any problems.

Are you sure the old o-ring didn't stay on the block when you removed the old filter? If you don't oil the new o-ring prior to instlling you have a chance of it sticking when you remove it later. I have seen exactly what you are describing from two o-rings being where only one should

Yep! It happened to me, first oil change on the new Bird. I didn't think anything of it at the time. I did catch it before it was too late though. This does seem like more than a coinicdence though. I wasn't really that rough when "snaking" the filter on. I think this warents some kind of corespondence with Motocraft.:mad:

Some years back I replaced a 3.0 Taurus oil filter. Failed to check it out. As I started to work the next morning, I noticed (nearly a mile from home) a trail of oil behind me.

Turns out that the OLD gasket had not come off with the old filter. The double gaskets did not seal, and most of the oil was gone. SO I walked home (at least the weather was decent) -- got more oil, tools, and rags to clean up the mess.

Rotten way to start the day. But no damage to the engine. It was still fine at 165,000 miles when I sold the car.

Yeah, I'm sure. I always check to make sure the old seal came off and is in good condition (ie not cracked, broken, torn, etc.) and that I put oil on the new seal before putting it on.

I just picked up the seal off the floor, wiped it off, put it back on the filter, oiled it and put the filter back on the car. After snaking it through, I made sure the seal was still in place and will always from now on.

I had the oil filter gasket get stuck to the block once and not notice it on a 1998 f150 with a 4.6 one time. I drove that thing down the interstate for like 5 miles and then when i got off the seal blew and spewed all the oil on the ground. It was a dumb mistake. It was a couple of skrewed up things in that ordeal. When I changed the oil i did it with the truck on the ground, so i couldn't really see what i was doing. When i removed the filter it fell into the drain pan and somebody else emptied the pan and threw away the filter. I didn't find out till later when I pulled the second filter off what had happened. I just got lucky that thing blew in a parking lot and not out on the highway.
