A blown head gasket or cracked cylinder head or block will do that. I don't recommend to drive the vehicle as major damage to other engine components can occur.

    Thank's their is no visiable leak just corrosion around the plug boot and retainer just found this while changing spark plugs.

    Then don't worry about it. That can be condensation. I thought you meant inside the burning chamber.

    You are OK. Have a Good Day!!

My number 6 cylinder in my 2002 Trailblazer is not firing I changed the coil pack is still missing

I don't know what testing you have done? A lot of things can cause a misfire, fuel--spark--compression. My info shows coil on plug ignition, did you visually check for spark at the number 6 plug? Did you check fuel injector pulse?

White smoke coming from tailpipe during cold start from chevy trailblazer 2005 ls

You need to determine if it is indeed smoke or steam. Water condenses in your exhaust when it cools off, when you start it in the morning that water will turn to steam. If it is smoke, it will linger around longer than steam. Coolant in combustion chamber (head gasket) is the most common cause for white smoke. Unless it's an older vehicle with a transmission vacuum modulator with a torn diaphragm, most likely coolant. You can confirm coolant by pulling spark plugs, they will have a crusty whitish/gray build up on the end.

What's the best spark plugs to use in 05 chevy trailblazer

After playing around for years with different plugs from coper to platinum I have found that the AC plug that came with it is the best replacement. GM plugs are now rated for 100,000 mi or 160,000 KM.

My 2002 trailblazer was missing, so I took it to the shop. They put a tune-up on it, but it is still missing. They said I need a timing chain, truck has 110,000 miles.

Timing chain usually does not cause a miss. It may run sluggish or even backfire, but a miss is like a spark plug with the wire off. Like a dead cylinder. Chevy timing chains do stretch but those engines can handle quite abit of timing. I had one with 120K miles and it was only off 4 degrees. That's nothing for chevy to handle. A tune up is usually nothing but a set of plugs and a hook up to a diagnostic machine. I would look deeper. Go out at night, start the engine with the hood open. Make sure you are in a very dark place. Look for sparks jumping from plug wire. Another way to to use a spray bottle of water. Spray a very fine mist of water around the wires. If they are bad, a spark will jump. Check cap for deposits. You can only hope that the plugs were gapped right.
Good luck
