I have an 07 na with 212 000kms and of course without fail , another leaking lower intake gasket. Should have been a recall lol. Anyway I've done this once before on my other 3800 and was just wondering if there's anything I can do while I have the lower intake off. I mean anything I can do while I have it apart that far. Like maybe the valve cover gaskets. I thought about the timing chain but was thinking if all that extra work is worth it for fuel economy or more power since these are almost bulletproof lol. Thanks for any feedback,
