So, my car decides to start leaking oil all of the sudden. And, it's leaking pretty badly.
I'm losing about a tablespoon every night the car sits. Mostly when very cold.

It doesn't look like it's coming from the filter, the pan or the plug.
My guess is the o-ring on the oil warmer. Agreed???



Any reason these just go out? Never had a problem till I switched to full Sythetic.
Thought the filter was loose or something. Now this...

 

I think I've seen some threads about the o-ring going bad as you pointed out.

 

How many miles were on the car when you switched to synthetic. I dont know how true it is but supposedly if you switch to synthetic when the engine has higher mileage(75k+) it can cause leaks.

 

75K+

 

yeah man its a orange o ring pull your oil filter off get i want to say a 27 mm deep well socket it may be a 24mm i cant remember but anyways and where your oil filter would screw on pull that little adaptor out and pull off the warmer cooler and you'll see it. easy fix

 

So, I changed out the stupid orange o-ring today. It is a 22mm by the way.
We'll see if the bish lactates all over my garage floor again tonight.

 

Synth' oil can be used on new, not-so-new AND downright old cars w./o. any kinda fear.
All it does is withstand much, much better the damaging effects of friction, high temps,
foaming, carbon deposits, etc. It won't "leak out easier" than dino' oil, as many believe.
It's probably the "O" ring deal.

 

glad the O-Ring worked out, easy fix. The synthetic oil probably has been clearing out a lot of build up that had the small leak clogged. You probably wont have any problems from the O-ring.

 

Fixed.

 

I've heard this a million times as well (don't know if its true...but I've heard it)

 

Yep. Dealership told me the same thing when I was buying my orange-ring.
