pushin blue

[chevycanada]

my motor has begun pushing blue alot lately, i did a compression test on it today and figure it would be low but every cylinder was between 180-190. i thought the rings were shot but i didn't think you would get that compression if the rings were gone. is there anything else it could be?
any info appreciated
thanks

valve seals.

Definitely your "Piston Return Springs".

If your noticing it at startup but not so much after driving it (maybe some at take-offs), I would say valve seals (which are a common problem). I don't know how mechanically inclined you are, but with a few tools and airsupply to hold the valves closed, you can do it while in the truck or you can have a mechanic do it (shouldn't be too much, but it all depends on where you are and who you go to). If you want more info let us know.

if you could guide me on how to replace the valve seals it would be greatly appreciated. this is the second motor i have put in the truck its just a temporary thing until i get a new one built. i do have some mechanical knowledge so if you can let me know or point me in the direction of how to replace the valve seals it would be great

It could be your valve seals and/or valve guides.
