Re: 05 sts v8 northstar oil leaks
Well, my 2005 STS with the N* does not leak a single drop and I'm just coming up on 100K miles...I think the mechanic is making a general statement considering that oil leaks were common on the FWD N* engines (case half leaks).
Well...thats pretty low miles for an 05. What I will say from my experience is that when cars sit and dont get driven, things dry out...I've seen 2 of my grandfathers lexus ES350 leak because the import guy who fixed the leaks said "its better to drive the cars than let them sit, cause stuff will just dry out" just my input....obviously we all want as few miles as possible, but cars that dont get driven tend to have this kinda stuff happe(not saying you dont drive it)...mine has 105k, and not a drop. IF its just covers and gaskets, im pretty sure you can find a reputable mechanic who is capable and far more reasonable. I agree with the other guy who said the older FWD had leak issues sometimes, I have heard that...but ive talked to a few mechanics and from what I can tell the 05 and beyond N* dont have too many issues with oil leaks.
Ya...obviously its kinda good/bad luck kinda thing....Could be also when the engine was put together things werent torqued exactly how they should of been ...maybe they started using different gaskets on 06 07 etc because 05's might of had some issues...but I think its just a matter of luck...I know 3 people at my office who have had 02,03,03 sts's and none of them have had the head gasket issues....not to mention on of the guys just sold his with 215k ...and the car was not taken care of at all...but he said it didnt leak at all. I have to believe you can find someone who knows engines and can replace for much cheaper...not to mention I wouldnt think it would happen again in 40k. I always take my car to the dealer for something techinical for sure...but any good mechanic who actually works on engines(not just brakes,shicks..etc) can replace gaskets etc...and probably way cheaper...parts probably arent expensive at all.
