can an oil filter be replaced the wrong way round?

Answer 1

Yeh, you can put them on inside out if you’re not careful.

Answer 2

With great difficulty.

Answer 3

Not really. Can be cross threaded, overtightened, sides can be punched  by using wrong tool. Or the old O ring can still be there.. All  cause leaks--always Check For Leaks after each oil filter change. Stop engine immediately if you see one.

  A drop in type can only go in one way. Its element can be damaged, the cover and tube might not be assembled right. O rings on these can slip out if not careful. I had an  old Honda with this type, it fit  over oil cooler adapter. Each time, I'd have to replace Both  O-rings. And be careful the  adapter did not slip  when tightening. 

Answer 4

The Devil has best answer

Answer 5

how do you screw in a sealed end !!!! others us if mesh filter , how do you stop the junk coming out of it if it is replaced . yes you can put them in backwards if there a mesh type .. but wont work as filter as good .

Answer 6

As much as like putting a condom on backwards.

Answer 7

No, the canisters pump oil "thru" them, not from one end to the other.

Answer 8

What's the wrong way around? There's only one spot with threads to screw the filter onto the oil filter housing. If you have a car with a paper filter read the directions.

Answer 9

No.  They were thinking about people like you.

Answer 10

That depends. 

There are two basic designs.    One is a metal canister (that has the filter element inside)  this screws on just one way. 

The other is a filter element that sits in a housing,  it would be possible to force this one in the wrong way. 

BTW:  

In regards to design one above,  you have to check the old filter to make sure the rubber seal came out and is with it.  Don't reinstall a new one over an old seal.  Also put some oil on the seal and hand tighten it.
