Need help ASAP..DD car is down well i started my vacation last week and decided to go ahead and fix the exhaust leak i had from the header gaskets so i replaced them with new MLS ones from GM and everything was fine. well i get back from my nice trip to austin and on my way to work this morning i was slowing down for a car to turn and there was a pop and now i have a loud leak somewhere and the car is idling rough. i am thinking it may be a head gasket so my question is how would i go about checking that? and does anyone have any suggestions as to what else i may need to look for

car is staying at regular operating temp but yes it does warm up quickly. i've looked around and i can see no sign of any coolants or liquids around the block.
i ran the codes and got p137,160,301,1133,1153...any suggestions with these?

nope..plugs were still in.
i have never heard of anything like that happeneing either...when i looked at the plug a small portion of the threads were stripped but the new one went in and fits snug so i have no idea what happened

o yes...i seriously thought it was a blown head gasket and even when i saw the plug dangling there just hanging by the coil i also thought the threads would have been stripped. my question is though...why/how would a spark plug be shot out like that? when i replaced the gaskets maybe a few days before i went through and made sure all of the spark plugs were snug

same here...i'm speechless really
but i have also noticed that after a month spark plugs on the drivers side sometimes come loose and i have to retighten them. not hardcore but when i move the connector boot i can kind of feel it wobble. think maybe someone who put them in before may have done something to cause this?

^^ This guy right here answered your question but you paid him no attention. You have detonation going on which is very hard on your motor. It is like a bunch of hammers in your combustion chamber. It backs the plugs out. Extreme heat there in TX and bad gas (too low of octane) could be part of it.

The tuner can see if the engine is "knocking" and pulling timing out. Hopefully you can get to the bottom of that before it hurts anything. Are you higher compression or anything?
