Exclamation Warning to those who change their own oil. Pls. Read.

I changed my oil today without much incident, as I've done many times in the past. Unfortunately, when I took the car out in the highway, I noticed my car was trailing behind a rather dangerous thick white smoke. My oil light was on and my first thought was that the Proline Oil Filter had burst! I pulled into an outdoor mall immediately since their was a Trak Auto their.


Well, to make this short, when I removed the oil filter at the parking lot, a rubber ring fell out. It was from the previous oil filter I had removed during the oil change! When I was putting in the new oil filter earlier that day, I didn't notice the old one had left its O-ring where the oil filter screws on to. So when I screwed the new oil filter on, the two O-rings rubbed against each other causing the other to twist and create a breach. This caused ALL the oil to spray out all over the exhaust and engine block. Hence the white smoke.

So, the next time you remove your oil filter, make sure the O-ring isn't on the engine! Otherwise, the new oil filter you put in won't seal properly!

This is not a flame, but I think I have seen this warning in every auto book I own. We should all keep this in mind.

Thumbs up

You're lucky... I accidentally dripped a little oil onto a hot manifold once and had to put out a nice underhood campfire.

BTW, thanks for the tip. I'll be watching that next oil change.

Also, make sure that the filter you are putting on has the ring.

Hehe, I actually had this happen when a buddy and I changed the oil in his civic. Well we got all done with it, and then fired 'er up to check for leaks and oil level. We heard this gurgling sound and then panicked when oil was flowing on the pavement beneath the car. Moral of the story, when you pull off you old oil filter, check to see if the o-ring came off with it. I never thought to check that before (been doing my own oil for a number of years) but I now check that every time.

Please don't take this the wrong way, but if you wipe off the area where the filter goes, like I do, I don't see how this could happen. I ALWAYS wipe off the sealing area on the bottom of the block to make sure it's dirt free.

I always clean the block face off as I love to see the shiny aluminum. Always worth check for crud there.

Been there, set a RX-7 on fire because of that. No major damage, but I've never made that mistake again.

I'm sorry...I don't make a lot of posts, I don't know a whole lot about cars, I don't don't wanna sound like a d*ck and I don't wanna incite some sort of flame war. But, I have to say that I've been doing oil changes since I was 12 and that's just the most ridiculously stupid thing I have read in a long time. I don't know about everyone else but that to me is just a common sense thing...

Shrub0,
it sounds ridiculous to someone who's been changing oil for 12 years (as it should...) However not everyone has been for that long, and some things aren't second nature. I've made a similarly stupid oil change mistake (don't pre fill your oil filter), and any tips like this are helpful for muffler bearings like me. if you already know it, good for you , I'm sure someone is proud of you.

That's one of the reasons I start the car and check underneath to make sure there is no leaks. There are other reasons too, like a filter with a bad o-ring. The list is long but remember to check for leaks ALWAYS... Cya, Gary

Everyone has different levels of expertise on cars. That's what this whole BB is about to me. Helping and sharing info isn't it? I've learned a ton of things here
I did a little FAQ that we have on the AZ site on oil changing. Here is my version on how to change the oil.

-------

Changing the oil on an Impreza has to be one of the easier cars ever to do
it on. Get yourself a oil drain pan and catch the oil to be recycled. I
take mine to the local Jiffy Lube but places like Autozone or Wal Mart will
take it too. You can even get one of those catch pans that have a lid and
pour spout. You can use it to transport the oil too.

It's not necessary to raise the car but, I usually put mine on some Rino
Ramps. It just gives a little more room to move around under there. I
always change the filter when I change the oil.

First let the oil warm up so it flows more easily. I remove the filter
first and catch the oil in the pan. After it stops dripping I wipe the
gasket surface w/ a paper towel. It's good to double check the filter
gasket didn't stick there on the motor. If you need a filter wrench to
remove the filter then it was on too tight. You should be able to remove it
by hand. It should be snug but not that tight. Then I remove the drain
plug, it's a 17 mm. While it's draining I prepare the oil filter. Put a
light coating of clean oil on the gasket, then fill the filter w/ as much
oil as you can. It will take a bit to soak in and you can put in more.
After the oil stops draining from the pan, put on the filter by hand only.
Once the gasket makes contact only go about a 3/4 turn more. Too tight and
you'll squish the gasket and start to hit the metal of the filter. If that
happens you can get leaks or worse strip something. Put the drain plug back
in. You are suppose to replace the crush washer that's on the plug but I
only do that every 5 or so changes. I haven't had any leaks so far. I don't
actually torque the bolt in there, I just make it snug. Fill the rest of
your oil down the filler tube, start the car and let the oil light go out.
Shut the car off, start it again and look under there for leaks.

That's the way I do it anyway. Oh yea don't forget to record your change in
your handy dandy car log book.

This is helpful to know. Another thing that makes it easier is a www.fumotovalve.com drain plug.

oh peaty---if you want a neat trick tht a subaru tech showed me......try poking a hole in the filter on the top of the filter(the bottem if it is on your car)...this lets the oil in the filter drain b4 your try to unscrew the filter off. this is the point tht i get dirty. if you do this all the oil will drain so that you don't have to 'race' the oil in the filter running down your arm!

This is one of the first things they taught us in autoshop in high school, so it's second nature to me. But I could see how it might not occur to someone not so formally trained.

Here's something else I learned the hard way: Always thread spark plugs into the block by hand! If you thread it with a wrench, it's impossible to tell when it isn't seated properly. All it takes is a few seconds for an improperly seated spark plug to strip the threads on the engine block. And that sucks.

i just got my drain valve and its going on this weekend. no more driving to the dealership for those damn crush washers that no one else uses (in that size).


also, as a FAQ, the drain plug can be painted on from the factory making it ridiculous to get off. this is how it was with mine. i had to take it into a shop where the tech, with it on the lift, had to hit the end of the wrench with a hammer to get it loose

oh, and another reason to warm up the oil first is to help it pick up all the crud in it instead of it sitting on the bottom of the pan.

Jeez. I was just passing on the information and for some of you who are car experts, you could get complacent and forget about this little "mistake".

If I prevented a car fire for others here, good. That's all that matters. Coz that was my point of proudly posting my stupid mistake. So I started changing oil at the age of 17 and I'm now 33. BFD! So I made a mistake! Maybe others will learn from it.
