Plenum Intake gasket on 3.8 gasket and torque.

[zipster223]

My first post here. It's time to change the plugs on my 2010 3.8 sedan. I'll have to remove the intake/plenum. Doing this requires some new gaskets but I'm not sure which ones. I see up to 4 but do not know if I need them all.

Also not sure what the torque specs are. My manual says 26nm but that seems high. Not tightening pattern lasted also.

Check out this video, the shows the gaskets and part number that he used and they appear to be used on most all 3.8 V6 engines. As far as the torque spec of 26Nm, that is 312 inch pounds which is pretty high for bolts. I would try to access the online manual for maintenance. I am currently waiting for a response from them and will add a comment when I get it.

This (intake manifold) looks wrong to me too.

Are the intake manifold and plenum the same? My earlier post said 26Nm was 312 inch pounds and is incorrect. I agree with you.

My engine unfortunately looks different.

Maybe share a picture of your engine?

First image is the VVT that is leaking. When I tried to order one, it gives me 4 options. Which one do I need? I'm guessing it's the left intake.

Different than my 2014 and others that I have seen. Your oil filter appears to be on top like the 3.3 V6 which makes me think you have the Series I 3.8 V6. Hoping someone can weigh in on this.

The car is a 2010 but it says the manufacture was in early 2009. I'm guessing the engine is a 1st gen.

Looks like bank 2 exhaust vvt/ocv. https://cargeek.live/docs/hyundai_Lambda_Engine_Guide_Centennial_Equus.pdf. Check page 11 for the diagram.
