    Help blown 3.2 engine

    New here - looking for advise or council from you wise ones here. My wifes '03 CTS dumped it's engine a couple of weeks ago on -24 degree morning here in Wisconsin doing 70 mph on I 94. We had it towed to our dealer ....who told me once they had looked at it that it needed a new engine .... and what caused it was a faulty PCV valve tied to TSB that states in cold temps the valve could freeze up causing oil to be pushed out cam seals. My wife said she had no warning ...oil light comes on ....a split second later no more engine ....she could hardly muscle it off the road ...scared the #$^&&% out of her! Has anyone here heard of anything like this? She had 68,000mi. never had any other trouble. Now the bad part ...we were orig. told cadillac was going to foot the whole bill ...man did we feel relieved and good! even gave her a loaner no chg. So they put a new engine in ...she picks it up the other day .... to only be shocked to find out that our dealer is saying cadillac is only going to stand behind 50% and she owes $3,100!! What the heck any ideas here on what to do?? She doesn't even want to drive the car any more! Hope to hear from some of you soon!

    That sucks I had the same thing happen to me last week. The only good thing is that my cts is still running after it spit out 3 quarts of oil. I have the parts ordered to fix it but what is Cadillac doing about this problem?

    Re: Help blown 3.2 engine

    Here's the bulletin if that's any help..

    Subject: Oil Leaking from Engine Cam/Valve Cover Seals During Extreme Cold Weather Operations (Install PCV Hose Kit and Oil Filler Cap)


    Models: 2003-2004 Cadillac CTS

    with 3.2L V6 Engine (VIN N -- RPO LA3)




    --------------------------------------------------------------------------------

    This bulletin is being revised to update the Parts Information section. Please discard Corporate Bulletin Number 05-06-01-007 (Section 06-Engine)


    --------------------------------------------------------------------------------

    Condition
    When operating in extremely cold weather conditions, some 2003-2004 vehicles with 3.2L V6 engine (VIN N - RPO LA3) may leak engine oil from the cam/valve cover seals, especially from the left side just below the oil fill hole in the cam/valve cover.

    Cause
    This condition may be due to the closed crankcase ventilation system becoming blocked by ice. When the ventilation system is blocked, the crankcase vapors and engine oil will then vent through the cam/valve cover seals.

    Correction
    In order to keep the water from accumulating and freezing in the ventilation system, install the Positive Crankcase Ventilation (PCV) Hose Kit, P/N 55558592, and Oil Filler Cap, P/N 12589430. Refer to the repair procedure in this bulletin.





    PCV Hose Kit, P/N 55558592, and Oil Filler Cap, P/N 12589430
    Intake Manifold Shield-ID No.55558589
    Screws (Qty 3)-ID No.11057371
    Oil Filler Cap-P/N 12589430
    Oil Filler Tube-ID No.55558591
    PCV Hoses-ID No.55558590
    Seal/O-ring-ID No.90467543
    Hose Clamps (Qty 2)-ID No.90298229
    Repair Procedure




    From the primary engine PCV vent hose adapter (8), disconnect the following:
    1.1. The crankcase ventilation fresh air (outboard) hoses (9).

    1.2. The dirty air hose (10).

    1.3. The evaporative emission (EVAP) canister purge valve vacuum hose (11).





    Remove the three bolts securing the primary and secondary engine vent hose adapters.
    Remove the primary and secondary engine vent hose adapters. Discard the secondary vent hose adapter (12).
    Important: Ensure the intake plenum opening is covered.





    On the bottom side of the primary vent hose adapter, enlarge the two existing 1 mm (.04 in) holes (13) to 4 mm (0.2 in). Ensure all debris is removed.



    Install new seal (15), ID No. 90467543, on the bottom side of the primary vent hose adapter.
    On each of the fresh air (outboard hoses (14)), measure and place a mark 38 mm (1.5 in) back from the end of each hose.
    At each mark, cut through the hose. Ensure all debris is removed.
    Connect and clamp the inboard hoses (dirty air and evaporative emission (EVAP) canister purge valve vacuum hoses) to the primary engine PCV vent hose adapter.
    With the label side down, use the two clamps, ID No. 90298229, to attach the two tubes of the new secondary engine PCV vent hose adapter, ID No. 55558590, to the two fresh air (outboard) hoses.
    Install the new secondary engine PCV vent hose adapter to the back of the throttle body and intake plenum.
    Install the primary hose adapter to the new secondary hose adapter. Ensure the secondary adapter hoses lay on top of the primary adapter.
    Ensure the primary hose adapter (with the enlarged holes and new seal) is positioned over the intake plenum opening.
    Over the hoses and tubes of both adapters, install the new shield, ID No. 55558589, to the intake plenum.
    Install the three new screws, ID No. 11057371, securing the new shield to the intake plenum.
    Tighten
    Tighten the screws to 8 Nm (71 lb in).





    Remove the existing oil filler cap and oil filler tube. Discard both.
    Install the new oil filler tube, ID No. 55558591, and the new oil filler cap, P/N 12589430.
