Exclamation Engine issue - P0024/P0025

Hi guys,
I have a 3.8 2010, and moved from IN to CA recently.
My CEL has been on for some time (almost an year) but it drives fine. The OBD codes P0024 and P0025 codes are coming up and due to that I can not pass the smog test to register the car in CA That was a non issue in IN.

I am showing it to a local mechanic here who has changed oil and oil filter, put cleaner in the engine, replaced one of the sensor and cam phaser (OCV) - but still the CEL is coming up on driving a few miles.

I searched and found a few threads where people having similar issue got their engine replaced from Hyundai under warranty.
My car is at 118k miles, so I am afraid to go to a Hyundai Dealer as the warranty won't be there.
Would you be able to suggest any course of action to get it fixed/pass the smog test?

Thanks in advance for your help!
AJ

I asked the mechanic and he said the timing chain seemed fine to him. He did not open the cover to inspect it though. He said he'll have to take the engine out, so that required much more labor for him.
Is there a way to tell that the chain needs replacement, without taking the engine out?

You may be able to tell by taking the valve covers off. And I don't think the engine needs to come out to put a new chain in.

Update: He took off the valve covers and the timing chain looked all good :/
Any idea on what might be going wrong in the engine?

the cam gear(s) or the chain skipped a tooth?

with valve covers off, rotate the crank with hand tools, check to see if cams are in correct position when crank is at DTC.
Might have to crank it 4 times to get the cams in the correct position (or close to)

The mechanic gave the car to Hyundai to get a second opinion as he did not find an issue there.
Now the Hyundai dealership is reporting the CVVT on the exhaust bank needs to be replaced - something close to $1800
Does this seem legit?? I'm starting to wonder how much $$$ to pump in considering the car is already at 120k miles

Well its a sheet show no matter what.
What kind of oil you put in it? Try draining and putting in a lighter oil, then wiping the codes and see if they come back. Just dink around in it for 10, 20 miles or so and then give a couple nice revs nice and high once its plenty circulated and warmed up.

You'll either get the code back sometime in that, or flush whatever may have caused them out if it correlates to the oil control valve.

To be honest, haven't heard much about that kind of thing with our cars but we did that with I want to say a Merc or BMW that was using way too thick of oil down in Arizona. Sure beat the several thousand dollar quote offered by the dealer there since it was out of warranty.

EDIT: Also the cam sensor for exhaust is like 60 bucks at autozone. Give that a spin.

There is a procedure to check the cam phasers for DTC P0024/P0025 but you need the Hyundai GDS system to do that. The OCV solenoids can be checked with just an ohm meter and there is a TSB that shows how to do that though it's pretty simple.

FWIW you can get a Hyundai GDS system off ebay for around $120 or so.

I thought the OCV was just a metal screen filter.
Maybe different on the 3.8


BTW the CVVT/ cam gear is like at most $500 and the procedure is pretty much the same as a chain replacement accept you replace the cam gear in the process.
So the part, plus labor which is about 2 to 3 hours. My assumption is they are marking up the price of the part.

EDIT: part number for the CVVT gear is 24350-3C113
Issue is whether it's just one gear or both that is having the issue... or if it's something else in the CVVT system.

About $120 for a gear on fourgreen

The OCV is a solenoid operated valve with a screen. To change out the phasers as I assume there is no way to clean them out, would mean the valve covers and timing cover needs to come off too.

On the 2.0 at least the OCV is just a metal screen filter.
On the 2.0 they made it a PITA to get out, because you have to remove the head to even get to it.
Unlike on any of their engines, where you just had to pop, a bung or a sensor.

The OCV was already replaced, and clean oil was changed 3 times along with engine cleaner - all the time some sludge was in there.

My mechanic got the car back from Hyundai after their diagnostic.
The cost for replacing the cam gear is looking to be $250 for the part, and about 10 hours of labor - totaling $1300 or so at his shop.
I'll ask him if the fourgreen gear would also work. Thanks for the link!
By the way, do you think this is a 2-3 hour job?

EDIT: Its the exhaust cam gear

Looking at how the accessories are laid out more like a 4~5 hour job, for someone that hasn't worked on the hyundai 3.8 engine before.

The accessories and resealing as he is put it back together is going to be the bulk of the time is going to go.
All that just to get access to the chain tensioner, just to remove the cam gear.

@Red - odd that they label the solenoid an OCV well on the 2.0 it's and oil strainer.

How reliable are these parts from fourgreen?
The mechanic insists on getting the original parts from dealership, in case anything goes wrong due to a faulty part.
Also, the timing chain and tensioners might need to be replaced as well

chain, tensioner, and water pump are good things to change since he'll be in there.
It's one of those things that "if you're in there anyways, might as well change them, instead of doing all the work to take it apart and put it back together again later".
If the engine has 25k~30k miles on it, then I say it's not really necessary.

And whether parts are genuine hyundai parts. I found that for our cars, most online vendors only sell OEM parts. You really have to be searching hard to find 3rd parts, unless it's something cosmetic.
You can probably find a few 3rd party parts from napa, oriely's, and those types of places (which would cost just as much as genuine parts online), which they don't stock on location anyways.

Hey guys, so I had to give in the car again to dealer for a second diagnosis as he said he had to take another look.
This time there's some new stuff that he's putting in:
"if we are going to replace the CVVT we would need to remove the engine timing chain cover and replace all related seals (valve cover, oil pan, water pump gaskets and intake gaskets)"

Since you guys know a lot about removing the cover, are all these things required to be replaced? This has increased the cost estimate by around $750.
On a side note: I can appreciate our car so much now after taking Uber daily in the Honda Odysseys and what not

They have to take the cams out to test or change the CVVT. So that means the timing chain needs to come off, which means the timing cover needs to come off. So yes all that is needed.
