    Does this mean that I need a valve job?Also,I have a small leak around both valve covers.Is this an easy fix?When I do fix those leaks is there anything that I should also do at that time.

    First of all, when you bought your K5, you joined the "Puff 'O Blue" club. Your valve seals are allowing small ammounts of oil to drip through into the cylinders, and it gets burned off when you first start your vehicle. You can fix the problem by replacing the valve seals, but I wouldn't worry too much about it unless you start to have a problem with spark plug fouling.....

    It also sounds like your valve cover gaskets need to be replaced. It's an easy, cheap fix.

    I dont call my K5 old blue for no reason. It just the valve seals no big deal. Someday I will get around to putting in new ones.

    You would think Chevy would have taken care of this problem decades ago! I had an 88 GMC shortbox (low-rider, please don't laugh) and with 35,000 miles on it it would puff a little blue on start up. It upset me so much to see a new (at the time) truck puffing blue on start-up that I paid $200.00 to have it fixed. Its just the valve seals, an embarassing problem but not critical by any means.

    My 81 Jimmy does it now too ( not for very much longer though) [​IMG]
