Every two months i have to add coolant . Looked all over under pressure and also when cold, Can't find a leak. No coolant in oil. Could it be going out the exhuast? Can i add some kind of sealer to the over flow tank? Also every now and then after truck sits a couple days i'll get a big puff of blue smoke on start up, valves?? 04 5.3 Yukon with 92 K. Thanks for any replys Bob

  The document signed by both parties is public information and Iran has already come out and said they will be tolling the Strait with Oman. But, do you.

  no - I did not cut open the filter btw. I did use a PF63 which I will do for at least a few years worth of oil changes just for good measure. I really don't trust dealers for these tasks - I have no issue using them for larger tasks, but I also tend to consider the value of my time in the equation and if I can easily do it myself in significantly less time than the whole process of taking it to a dealer I will choose that every time. I am a very competent mechanic - I have built cars, engines etc. from the ground up and maintained race cars for years and years, built hot rods even from newer platforms with EFI, swapped engines, transmissions, brakes, rear ends - you name it. Oil change is pretty mundane and I can have it done in the time it takes to drive to the dealer let alone drive back and wait for them to do it.
