Why, oh why is this car STILL leaking oil?

Question

Back in April I took my car to garage (2005 Kia Sorento) to have an oil leak diagnosed. They changed gaskets and I paid $694.00 for this service. Two weeks later it starting dripping oil again, not a lot, just enough to notice on my driveway.

Finally I took it again last week and the pvc valve was changed. When I got home my husband drove it one time and I had to have it towed because the radiator gushed liquid out......puddle under my car when I picked up from the pvc change. I believe they pulled the hose away from the radiator (though accidentially), I had to pay for the radiator fix.

I've spent more than $600 this month and my dang car is still leaking oil. Two ?s

1 - Shouldn't this be warranted?  I've only driven 6,000 miles since April.

2 - What else could it possibly be causing this car to leak oil? It seems since they changed the pvc valve that it leaks even more.

PLEASE HELP!

Warrantied for what?

Chances are its a rear main seal leaking, for that they have to pull the transmission out to change it.

The car is 9 years old and if it has anywhere near or over 100k a minor oil leak is to be expected. I would not worry about it and just check the oil level once a week, and add as needed.

PCV valve should not be the source of an oil leak, it could be the oil pressure sending unit leaking, valve cover gaskets, oil filter not tightened properly, front or rear main seal leaking, cam shaft seal leaking, or any other various seal the engine may have, even head gaskets can leak oil to the outside of the engine, I have seen it.

No if its a different seal or gasket than the one they changed its not a warranty issue.

Wash the engine carefully, then drive it a few days get under it or look in the engine compartment and try to find where its coming from its your car you need to do some detective work. The oil is coming from somewhere you need to find it, then get it fixed. leaks can be a pain but are to be expected on older cars, trust me I have had my share.

I spent about 5 grand having an engine rebuilt it didn't run so good when it needed rebuilt, but it didn't leak oil. I got it back and it ran like a new engine should but leaked oil like a sieve, I had to take it back 3 times to get them to re do the valve cover gasket, seal the bolts holding the distributor on they go into the oil galley in the head, and had to get the rear main seal replaced again all was free for me because it had just been rebuilt, but it was annoying paying that kind of money and I bought a problem. Its all fixed now and the car runs great and no leaks but it was a fight to get it that way.

I have had older cars too that leaked oil and I just kept a couple quarts on hand and checked the oil once every week or two also and added as needed, the choice is up to you to fix it or not and just live with it!

When engines get old and well worn, the best PCV in the world won't handle the blowby gases.
The result is pressure rise in the crankcase and sump, and if there is a weak gasket or seal anywhere, oil will be leaked.
The other effect is loss of power, as the PCV passes too much of the blowby gases into the engine intake, leaving less chance of getting fresh air supply.

no they didn't pull a hose for your PCV valve (positive crankcase ventilation)

the original leak puddled somewhere that will continue to drip for a little bit(unless they steam cleaned her)

its an almost ten year old korean special
