    I am a proud new owner of a 94 Quest. It drives nice, I had it checked out. Great van. There were some issues with it which I will fix, however I purchased it at a great price.

    I heard and found some posts on the internet of these having warping exhaust manifolds, then breaking head studs and it costing a lot to fix. My questions:
    1) Have you had this problem? Was it expensive?
    2) Can I do anything to alleviate this from happening?
    3) Is this a REALLY common problem? I haven’t found 1 post on here about it.
    4) Have you had a Y pipe issue? This was another thing I heard about them.

    The broken exhaust studs are common on this engine. Nissan used larger ones for the 3.3l to fix this problem. I too had the broken studs when i bought my Quest. Pretty easy fix, I removed both heads and took them to a machine shop to replace the studs that was 10 tears ago. This is a great time to get in there and go over every thing. I do a lot of looking on the net for info on our vans and i have never heard of warping manifolds or y pipe issues.
    Good luck!

    When you have broken studs you will hear an exhaust leak at the manifolds. Has nothing to do with idle quality.
