    Had some oil leaking from the left front of my car

    Last week I saw some oil on the floor of my garage. It was under the left front corner of the car in front of the front wheel. Probably coming from the charge pipe connection to the intercooler. So, I took it to the dealer. At first they said there was some leakage from the valve cover. Ok, makes sense that it could be the PCV valve. They said they would replace the valve cover. Sounded like a good plan.

    Then they didn't call me back when they promised. I finally got hold of them a day later and he says that called GM tech support and they think there's "too much pressure in the engine" (their words) and they want to replace the pistons and rings.

    I assume they are concerned about the rings leaking and getting blow-by into the crank case. I'm a little nervous about this. I'm not entirely sure that this is the cause of the problem and haven't had any experience with this dealer before.

    Any thoughts?

    Since you haven't mentioned any prices, I'm assuming this is being done under the powertrain warranty. I don't think GM would authorize that unless they were pretty sure there was a problem.

    It was not uncommon for the 2011-early 12, and sometimes later models, to crack a piston at the ringlands.

    Ask for them to do a compression test and provide you with the results before you authorize them taking your engine apart. And ask how many the tech working on the car has actually done. Lots have had a piston or two lopped in that broke, and are still driving their cars today. A small handful had more unpleasant experiences.

    This is very true its not uncommon at all. You know OP my Cruze had oil coming down on the passenger area like you are mentioning they changed the throttle body they changed the PCV trying to fix the problem, they was unsuccessful in repairing the final diagnosis found broken ring lands on #2 & #4 pistons - so they rebuilt my engine & 1 week later - melted intake. Then complete engine replacement.

    I am not saying this is your issue - but unfortunately you may be experiencing the same dreaded piston issue. - But be sure to update us all on your progress & your outcome w/ GM & good luck!

    Thanks for the concern.

    They've had my car for almost 2 weeks now and are "still waiting on parts". I am not at all impressed with the level of communication I'm getting from this dealer. For every 3 calls I make I get one back.

    We'll see what happens next week.

    I got my car back on Saturday, almost 3 weeks in the shop. But,they fixed everything!

    They replaced:
    - 4 pistons and rings
    - Timing chain
    - Intake manifold
    - Valve cover
    - Charge pipes
    - Water pump (I didn't even mention this to them)

    So far, so good. The only problem is the CEL is on - P0236. Could be from something they did. I need to connect my scanner and see if there's a boost problem. If so, I'll take it back. Or see if it clears itself.

    OP, if I may ask, what is the build date of your Cruze? (It's found on the drivers door sill sticker)
