Hope for a good outcome. My concern would be that at 170K you are entering the nickel and dime stage. And you will see that a new engine aint cheap.
if they dont cover it, buy a new gasket and put RTV Black silicone in that corner of the cover.I have had a 2008 Vera Cruz GLS for about two years now and it has the oil leaking onto the alternator issue. Looked it up and it was done in April of 2015. Hopefully they will cover it again. Mine has the ABS,TSC and AWD lights on all the time. I have read that it could be the oil leaking causing these lights or wheel speed sensor. I also have a start up issue. Turning the key gets nothing sometimes other times it fires fine.(I have opened a thread on here for that.) Also the keyfob only unlocks drivers door and hatch. Does not lock anything. Dealer programmed it and I did not notice it would not lock anything until I got home. Just frustrated. I like the vehicle and would like to keep it if I can get these things fixed.
