    Thanks, Andy. That was more helpful, I said in my experience they always smoke at startup, but my experience doesn't include seeing them fail. I always got them after they were wasted. It just seemed to me that kslust just wanted some suggestions before looking at the expense of replacing seals. It also seemed like he was saying it just started or he just noticed it. I would suggest the pcv because it is cheap and is also a maintenance item, then if he is always filling them at the same station, try a different place because they may have contaminated fuel, then some seafoam to clean it all out. Plus the thicker oil like you guys said if it is still smoking. I understand his frustration, it doesnt look good to the customers to see that.

    More symptoms! PCV Valve is saturated with oil, changed it. Still saturated. Doing a leak down test, will come back with results and hopefully a solution.....

    Results from leak down test; All cylinders with the exception of 1 is only showing 0-5% compression loss. The other cylinder is showing an 18% compression loss and air hisses out of the oil cap?!?! Yeah..... Burned Ring. If anyone else is experiencing an issue like this, I think I have got a fix. Problems 1) Car smokes when pulling away after idle (embarrassing) 2) Car burns about a quart of oil every 7-800 miles. If I can alleviate the problems and not affect the performance then, kool right?? So, I took off the hose from the PCV valve into the throttle body which moves the oil from the engine and into the throttle body and being burned off causing loss of oil and smoke. Plugged the hose fitting on throttle body and added a breather (filter) to the PCV valve. By doing this the oil will go through the PCV valve and be stopped by breather and eventually drain back down, letting no oil blow by into the throttle body. So..... In theory I have alleviated all the problems without sacrificing the performance of the car and MORE importantly having to replace a motor. I have tried it over an hour idling and NO smoke!!!! I will see if any oil is lost during driving, will check stick in about 500 miles?!?!?! Crossing fingers here!!!

    Doesn't matter? Yes, I'm using 10w30 now (hoping not to beat up the motor to much).

    Some people like to put their patches on their shoulder, but that might cause a problem as not all roads you will be traveling on have shoulders. My recommendation is a (control) arm.

    Switch to full synthetic, If you are burning oil synthetic will not burn therfore you will have no smoke! Just make sure you check oil at every fill up and top off as needed.

    You may want to try pouring about 4-5 ounces of top engine cleaner down the spark plug hole of the offending cylinder and letting it soak for 2 hours, it could be a carbon sticky piston ring. Your pcv fix is very unconventional. Steve

    So............ Yay!!!! No smokey!!!! I managed to stop the smoking, but it does still burn a little oil, about 1.5 quarts in a 3000 mile period?!?! Breather replacing the PCV hose is working pretty good!

    1) I will try that "Top Engine Cleaner" bit.
    2) What do you mean "Unconventional"? I thought it was a pretty good idea?!?! It seems to help at least even if not completely fixing the problem.

    P.S. I love the Nicoderm Patch Bit!! LMAO!
