Sometimes I notice a bit of intermittent smoke from the tailpipe,especially on acceleration...also I added oil the other day,been driving a bit,and today noticed on the stick it seemed low again. Mechanic said last time he checked it noticed there may be some leaks from the valve cover. What's up?

 

are you getting smoke from your dipstick tube while its running? is there oil under your spark plug cover? sounds to me like a typical PCV system issue.

 

Im getting something like this too, Bit of smoke puffing out of the dipstick hole when running. Youre not alone! Im going to tackle the PCV this weekend, is it difficult?

 

Its fairly easy, just will take a few hours

 

just dont forget to put the bracket that holds the lines that runs around the engine on top of the intake manifold, NOT between the block and the manifold.
I did thAT AND COULDNT FIGURE OUT WHY THE CAR WASNT STARTING FOR 2 days...

 

Not hard just takes time. Took me about 6 hours. Make sure you have all the tools you'll need or it will waste a lot of time running back & forth. I have a list of stuff you'll need but if you go through the instructions in the sticky you should figure it out. Be sure to get some long curved needle nose pliers & those funny clamp tools and whatever you do, do not loose your intake bolts.

 

After you do the PCV. Will their still be a small amount of smoke that comes out of the oil dipstick when the car is running, Or should that stop all together?

Dirty PCV leads to abnormal oil consumption -- insufficient lubrication. This leads to excessive wear of piston rings. Wear of piston rings lead to more blow-by, which clogs the PCV, and results in front and rear seal leaks. Clogged PCV also causes oil consumption, which causes poor lubrication and the circle continues and problems get worse.

Instead of cleaning PCV every 60k miles, a 30k miles is in order. Then a 20k miles, then a coca-cola catch-can, etc. etc.

Turbos just exacerbate the problem.

Outside of doing piston rings, keep babying the PCV and stay on top of the oil.

 

If it still smokes after the PCV service it might be the valve seals. I have had a rash of cars lately with bad valve seals. Most do not want to fix it and run 20/50 oil.
