    Hello all. My eclipse has had a problem with oil leaking into the cylinders since I originally bought it and possibly a compression problem (or maybe it's just slower than i think it should be, I haven't done an actual compression test yet) and I can see blue smoke on startup, so I believe it to be bad piston rings. However, the car only 70k 2 days ago and hasn't been beat on as far as I know, so I don't think the rings should be going bad already. Thoughts?
    Thanks in advance.

    If it only smokes when you first start it after its been sitting, it's most likely your valve stem seals.

    I never got to drive the 420a as 100% stock, but I can tell you that it probably couldn't get to 60 in 8 seconds.

    Is that a simple job? Or would I have to put it in the shop to get those replaced?

    Depends on your level. Valve springs have to come off to replace them. Haven’t touched a 420a but that’s pretty much most engines. You’ll need some tools as well. Seals themselves aren’t much.

    When he says valve springs have to come off, I assume you know that means the cam shafts have to be removed.

    If you have the right tools you should be able to do it yourself.
