i've got 95k on my tibby and i just did an oil change. i turned the car on to fill the oil filter, checked it, decided to put another half qt in, but... when i opened the oil cap off to put in the oil there was white smoke coming out. whats up with that? never saw that before. my engine has been sounding rough like theres a lifter noise, and some other things...

 

Your confusing me.

 

sorry... let me make it simple. i took the oil cap off to pour oil in (where the cover to the spark plugs are) and there was white smoke coming out of there. is that normal on high mileage vehicles? i did the oil change and turned the car on for a few minutes then checked the oil dipstick and went to put some more oil in. thats when i discovered white smoke. not a whole lot.. maybe like the amount that comes off a lit cigarette.

 

Question: is there white gunk on top of yoru oil cap?

 

Clogged PCV system. Change your PCV valve.

without the vacuum from the PCV system, the unburned fuel and blowby gasses stay in the engine longer. Sometimes overnight. If you havn't changed your PCV, you should do so. It's a $3 part and it takes about 5 minutes.

If you have changed your PCV, you should inspect it. You can do so by shaking it back and forth to listen for clicking on both sides of it's throw. it's basically a plunger on a spring and you should hear a metal on metal clicking both ways if there is no metal on metal click, then it' clogged with oil and gunk. If you just changed it, then your internal catch can is probly clogged. see the DIY on cleaning your PCV drain.
