I just bought my first 03 350z touring edition and i noticed oil coming from the valve covers. I got it too the garage and white smoke was coming from the exhaust along with some smoke from the passenger rear of the engine. It doesn't seem to be leaking anything but there is some milky residue in the oil cap. I am a first timer so any info that would help to identify the problem is appreciated!

-Has 208k miles

 

yeah, coolant in your combustion...

 

Your engine is shot. Coolant is leaking into the engine’s internals. The only repair is a rebuild or new engine.

 

To confirm how bad the engine might be, drain your engine oil and send off a sample for a UOA. Was this a private sale or did you get any kind of warranty from a used car dealer?

 

wow, you just got taken

 

Milky oil could also be the car running on low oil. If you run it less than 2 quarts it will do that

 

Have these things verified before jumping to conclusions...

 

have a professional look at it...another thing I though about was your water pump seal may be bad. You could be leaking coolant into the timing chain case...If you are pretty handy and have a good set of tools and a little knowledge you could put a new water pump in over an afternoon.


just a thought...

 

You bought a 350z with 208k miles? Wow

 

OP, what'd you end up paying for this 2003 / 208k z, did you get a deal on it?

I'd buy a 2003 with 208k on it if the price was right?
