Oil filter/engine damage and warranty coverage

[Mark_888]

This is why I do my own service work.

Interesting though - nowhere in this thread is it explained what actually happened. Cartridge type oil filters don't leak. The filter housing/cap and the pan drain plug are the only possible source of leaks. On the so-called "cartridge" system favored by Hyundai, the paper filter is completely enclosed within the filter housing.

The plastic cap can leak if the o-ring is not installed correctly.

Can I ask how this was resolved? My engine just died in a similar fashion in my 2009 Genesis and they are denying coverage because they are blaming the oil filter. Seems to be a theme.

Who did the oil change? What brand of oil filter was used?

But nobody's talking - certainly not the dealer

Cartridge type oil filters don't leak.

There are several sources of an oil leak using cartridge filters.

Bad gasket. I have experienced this once but luckily my preferred shop caught it before trying to install the new filter.

Cartridge doesn't seal properly. This is usually an installer issue. They don't seat the cartridge properly when tightening the bolt so there is a gap between the filter housing and edge.

Most cars today use screw-on filters so most shop techs have not seen cartridge filters before (they were common on English cars several decades ago). I know from personal experience they are more complicated to install than a normal screw-on filter.

All true - but the filter used in the cartridge system cannot be a source of a leak. It is completely enclosed.

That said, there are plenty of opportunities for screw-ups. A previous poster mentioned the omission of the large O-ring, for example. And, with the V8, the filter is suspended between two separate posts and requires extra care in installation.

Spin-on filters are far less subject to such screw-ups, but the argument against them - believe it or not - is environmental. They are hard to recycle and it has been said that Calif. alone throws away enough spin-on filters every year to re-build the Brooklyn Bridge. I haven't personally counted.

The original post, 3-1/2 years ago said that the oil pressure light would go off and on, along with the check engine light, and then he DROVE the car to a dealer.

Most people know that if that happens, you should stop the car and get a tow.

Expensive mistake.

How in the hell could many quarts of leak out of the filter and the owner not notice?? I don't get it

John

if it has a cartridge oil filter it is sealed within the engine and will not leak on the ground it will only bypass the oil filter and send contaminated oil back to the engine causing the damage

the oil dose not need to leak out to cause damage if the oil filter is installed improperly the oil can bypass the filter and go back into the engine

Oil bypassing the filter does not damage the engine. It also does not cause the oil to run low.
The bypass valve is there because it is 100% better for the engine to get unfiltered oil than to get no oil (clogged filter).

Correct. Now try to prove that for a short time that caused the damage on an engine with 100,000 miles. Was any of the oils saved for testing?

i must be looking at another post i see nothing that says low oil caused the damage it says the oil filter did the damage if oil bypassing the filter dose no damage why do we have them I know the bypass will open if it needs to but if u have no seal on your filter a lot moor oil is going back to your engine un filtered

yes you are correct unless this was done multiple times and you could prove it that would be a hard argument to win

The first oil filter I bought for my 2010 was missing an O ring on the filter itself (not the O ring for the filter cap). I had to go exchange the filter for another one, because there was supposed to be an O ring in both ends and mine only had it in one end. Who knows what damage may have ensued if I had just installed it without checking.

Always check your new oil filters.

A little oil would have bypassed the filter. For one oil change period, that would have done no harm at all.

Even at normal operating pressure & volume? If that's true, I'm glad to hear it, just a little surprised, that's all. But thanks for the info!
