Hey everyone, i just noticed today that there is oil leak on my car. I looked underneath the car and the only place i see the oil is under the oil pan. It's not a major oil leak but still, so do you guys have any idea what's causing the leak? I did an oil change about 3 months ago and they used the mobile 1 0w-40. I was thinking that they might forgot to tighten the screw or something

Most likely they re-used the copper crush washer on the drain plug instead of using a new one.

a picture is worth 1,000 words.

Yep, the picture would help, there are a couple of places it could leak. Mine started with the front crank seal leaking about 1K after a service. Completely unrelated, in my case and relatively inexpensive to fix.

I'll get under my car today after work and try to take some pictures

It's really hard to determine where that is. Did you remove the plastic underbody panel? If not, it's impossible to determine where the leak is coming from.

Looks like the pictures were taken with out removing the plastic underbody panels.

Please re-take the pictures with those panels removed.

^^^^Take of the plastic cover, clean the area, wait a few hours and see where the oil is coming from. I had a recent oil leak 2....the oil pan screw and the copper washer were the problem...Luckily i needed an oil change, so it was an easy fix.

My bad, there we go. i just took the cover out and here what i found

Looks to be the copper crush washer. Like e1000 said, they probably reused the old one instead of replacing it like they should've. Get a new washer and torque to spec.

jerryml430

will do, thank you all for your help

pcy

in the posted picture (above), I don't see the copper crush washer at all. My guess is that whoever did the oil change, they didn't even put the copper washer.

Good year place did the job, and they charged me $136. I'm not going there anymore

e1000

Do you know what kind of oil they used? Probably a good idea to stay away from thaty place.

+1 That would make me really wonder what else they didn't do right. "Oh, this oil will be fine, it is close enough to what it calls for."

jerryml430

I requested the mobile 1 0W-40, and I was looking at the paper work and it said that they used about 9 thing of mobile 1 0W-40 and they charge me about $10 for each

You will need to remove the drain bolt, put in a new crush washer and you will need to put the drain bolt back on. When you remove the drain bolt, all of the oil will come out - you will have to decide if you want to collect the oil in to a container and pour it back in to the engine OR pour new oil.

When the Goodyear folks changed the oil, what kind of oil filter did they use? paper media type or fleece material filter?

pcy

By the way, you can buy a set (100) of assorted sizes copper washers from Harbor Freight for $4 or so.

If possible you should do the oil change yourself.

samaritrey

I would just replace all the oil just so you know that it was done right with the correct filter.

I just did my oil change today.
How come mine does not have a washer, just the bolt itself.
Is it necessary to have it?
BTW I have 2005 C230.

samaritrey

they all should have the 14 cent crush washer. and you have to replace it every time you do an oil changer or you will have problems. Heck when i did mine this way i replaced the bolt to because i could tell someone did not put it back on right way overtightened and rounded off some. rmeuropean has both for less then $2 lol

jerryml430

If i'm not mistaken they used fram fleece oil filter, it sucks that I have to waste the oil now. I barely got the oil change, its only 2 months. I'm thinking to check if dinan still doing the free oil change, since I live close to campbell

fookoo303

don't waste it. bring it back to them and show it to them. They should be more than inclined to remedy it, and you won't have wasted 130 dollars.
