Oil Filter
Have any of you heard of an AC Delco (PF48) oil filter leaking?
A friend took his Vette to local dealer for some work which resulted in an oil and filter change.... got it home and it left a puddle on the floor. He took it back and they said the sealing packing was made wrong and even though the filter was tight, the seal leaked.
They said they see it once in a while ... have any of you experience such an issue?

I think they didn't tighten it properly and using the "defective seal" to cover their butts.

Hmmm?
Sounds good

Don't we ALL love the dealers? Well...?

It could also happen if the filter is over tightened. It should be hand-tight. More than that and the base of the filter can be distorted.
I've seen it happen when the oil change flunky used a filter wrench to make it 'good & tight'.

Sounds like a oil filter double seal issue, that usually results in a leaker.........
Double check when changing your oil filter that the rubber seal remains with the old oil filter not stuck up in the engine block.

Never seen an oil filter of any make in 45 years of DIY wrenching to leak except when a dealer gave me 5 free oil changes with my 98 suburban purchase. Leaked several weeks after the oil change on 2 of the 5 changes due to the QuickLube Monkey failing to install tight enough. I crawled underneath to stop it myself on those two occasions.

I think mechanic error is more likely but it could have been a defective part. All's well that ends well....you got it fixed with no damage to the car. 
FWIW I prefer a bit more than "hand-tight" especially if the car sees 'vigorous' use. I've seen oil filters (and drain plugs) vibrate loose. I wouldn't tighten a filter to the point it crimps the seal but for me I'll wrench it more than hand-tight.

Then compare them. Both are cheap and made in the same place.
Buy a Wix! Much better filter!

+1 on the error being from the installation.
Ive had maybe 3 to 5 oil changes done by dealerships in my life. The oil changes were free with one of my cars. After the tech left the filter loose and I had a puddle of oil in my driveway, I decided it wasn't worth the free oil and filter.

I'll stick with the "D" man! or food for thought.
I will stick with the Delco filters for a few very good reasons.
1) "No question" that your warranty will stay in effect.
2) Many people have used the GM filters the whole life of ownership, be it short or very long with no problems including engine wear, etc, from the use of the Delco filters.
3) From what little reading on filter quality including anti-drain back valve design, etc. the Delco's design is superior in a lot of comparisons and must be good enough that GM trust's the filters design & construction to protect their engines through the warranty period.
4) Design is very important; just like the ZR1 air filter meets GM specs. but is suppose to flow more air than the Z06 air filter because from what I have read on here GM uses a little less media in the ZR1 filter to get a higher flow rate. Well just stuffing more media into an oil filter just because its possible "may" reduce engine oil pressure and flow rate which is not a good thing. The amount of media in a Delco filter may already be more than what is required.
So there you have it, now chew on that for awhile.

I had a filter that didn't flow. I started the engine and waited for the oil light to go out after an oil change. The light didn't go out, I shut the engine off to investigate an discovered all five quarts of new oil on the floor. The oil filter seal failed when pressure built up beyond limits. The auto parts store replaced the filter and oil, but I had to clean up the darn mess. There are defective filters.
