Got 4 Bosch's on sale and should have checked them all out at the store. Shook them and the internals of one were totally loose. So what's a BITOGer to do?

Show it off!

The friggin leaf spring was put in upside down like this:

Should be like this:

And the center tube only had half the holes as normal:

2nd time I've bought a Purolator clone that's been all messed up.

I'm sticking with the Napa Proselect from now one. Not the greatest media, but they are built like a tank and only cost around $3 bucks.

I couldn't really cause the parts jockey looked the part numbers up and was courteous enough to get them for me. Didn't want to look like a total jacka$$ at the counter!

"Sir, why in the [censored] are you shaking all the filters?"

I always examine the filter before I leave the store with it. Shake it, smell it, look down the tube for any odd or foreign material, check the threads for burrs and check the seal for the right fit and smooth surface. Check the can for dents or any other imperfections. It is very unusual to have problems with a Wix filter.

I really like the ProSelect filters. I use both the ProSelect air and oil filters and they are very well built. The media in the ProSelect oil filter does not concern me in the least. I change my oil and filter at every 2800K to 3K.

Is that because neither work? Both filters and watermelons require a visual inspection. The stem tells you the condition of the watermelon. A green stem is a green melon, suitable for consumption next week. A brown stem is a ripe melon suitable for consumption immediately. Both kinds are desirable depending on your situation.

I heard about thumping for years and never got consistent results from it. Then a friend that worked for grocery told me about the stem trick which gets me good results every time.
 
I look inside oil filters with a flashlight and wipe the threads with my finger before buying. If the threads are dirty or the insides don't look good, I put it back. It's also good to check the part number to make sure someone didn't switch boxes on an expensive filter and put the cheap one back.


I bet they have a guy at the filter factory who's job it is to shake filters, all day long.

All of my purolators and purolator clones were fine.
