I just did an oil change the other day and noticed this leak immediately after words.

It is a 2006 NA manual with 112,000kms (65k miles).

I didn't change the O'ring on the oil filter cap when I swapped the filter. Do you think I could be leaking down the oil filler cap and presenting down here?

Anyone else seen anything like this.

I apologize as I am color blind so I struggle to determine the color of the fluid. Judging by its location I do not think it is coolant.

Any insight is greatly appreciated. I am going to pull the filter now and look at the O'ring and replace it.

Update

I think it was the O'ring on the oil filter cap. The image below is after I wiped down the surface. Prior to this, I could see oil on the rim and up and over the O'ring on the filter housing. You can see pooled oil in the crevices around the oil filter

I hope this is the root cause. We will soon find out.

Though I am fortunate enough to not be colorblind, I usually “smell” the fluid if I can. Usually by the time I find a leak it has dropped down and spread, mixing with road grime and lost whatever original color it had.

I do however discourage “tasting” of any car fluids as a general rule :)

or just spilt oil from changing the filter,I hate those type filters. shame on gm for using them and the companys that make the filters that wadd up when tightened down. I bought about 10 of the made in france GM filters that are a zig zag pattern that dont wadd up.they are the only ones made correctly to compress and not wadd up. with 2 solstices they may last me a life time.
