Blue Smoke only at start up

Recommended Posts

Hi...So since quarantine, my car has been sitting for longer periods of time than normal.  I do however make a point of starting it every 3-4 days to get the fluids moving.  One afternoon, while outside, I remote started it and notice a small plume of blue smoke come out of the exhaust.  Thinking it may have just been a fluke, I shut it off and let it cool down.  I re-started it about four hours later with the exact same result.  I know blue smoke usually means burning oil, but I'm not sure what could be causing it.  My car has always had unusually slow acceleration (unless you punch it, which then, gitty up!).  It's a 3.6L 2014 Ltd with only 148K km's.  The engine isn't throwing any codes.  I recently, about five months ago had the timing cover replaced due to a small oil leak.  It fixed the leak, but I'm not sure if perhaps it caused this?

Valve seals! then change the plugs...  google it

 

otherwise when you shut the car off, the oil seeps thru the valve seals and goes in combustion chamber and will burn off when you start it again.. Wont hurt nothing other than youll have to add oil occasionally and also will have to change the spark plugs more frequently!!.. til you fix it! PS: run thicker oil,,,

Watched the video and noticed he said that it will burn blue for about 5 minutes.  For me, it's basically 5-10 seconds then transitions to white smoke then followed by clear exhaust.  I would rather start with a PCV valve as I had my spark plugs replaced by the dealership about a year ago and noticed from the invoice that there is no mention of the PCV valve being replaced at the same time. If it is easy enough to do on my own, I would prefer that. 

 

If that doesn't fix it, then I'll have the dealership  troubleshoot the valve seals as I know this is not something I can do on my own.

 

When I start it, I do sometimes (about once a week) try to take it on the highway or at least do some city driving.

5 minutes smoking if its really bad.. otherwise first 5 seconds is valve seals also! ask a mech if you don't believe me.  you might get lucky and it will be the PCV.. I doubt it though.  Pull the pcv and shake it.. does it rattle.. YES then its working!

Sorry, I didn't mean to make it sound like I was questioning you...Further from the truth, I appreciate all feedback I get.  Although not a mechanical beginner, I'm also not a mechanical expert either and this issue is new to me.  This Journey has been a journey through my wallet and bank account and to fathom I may have to drop some more serious coin on repairing valve seals makes me regret the day I bought this thing.  So far, I've replaced the oil cooler, thermostat, cam shaft pos. sensor (needs to be replaced again, was replaced only two years ago), timing chain cover, serp belt and tensioner, ball joints and soon struts.  I can only imagine valve seals will be a costly repair.

 

If anyone can point me to the location of the pcv valve on a fwd 3.6L, I'd appreciate it.

 

Cheers!
