Engine flush

would it hurt to do an engine flush on my Chevy 6.0 ? I have run Mobil One since 20k. I noticed my lifters are a little noisier now that it has 210,000 miles. I am due for an oil change and was considering Seafoam or possibly the old timers way of adding some kerosene ad letting it idle for 10-15 minutes. Or should I just change the oil ?

    Also certain oil filters cause this... I only use the delcos from advanced auto. When I used the purolator's on my current 06 I get some noise .


    I run mobile 1 and run 1 qt trans fluid once a year... 95K on odometer.
  • IMy 96 had a sticky lifter @ 170k miles. Twice a year I added 1 qt trans fluid to the oil when I was a qt low just before an oil change.

    Drive it for a couple hundred miles. It will clear those lifters and the weep holes hopefully.

    If that dont work pull the covers and spray some blaster down the rods to clear lifters..

    Watch this..

  • Don't use that snake oil. If you want to do something to clean it out, just use good oil and change it more often. I bought an older vehicle that had been neglected and changed the oil about every 1k miles for a few times. It came out nasty the first few changes, too.

    Better to slowly dissolve any deposits and take them to the oil filter rather than put solvent in there and suddenly break it all loose.

    Make sure your PCV system is good too.
