Ticking like a Time Bomb (Engine Noise)

[Hellz]

sure it is not a broken exhuast manifold bolt?

very very common problem for the H2.
symptoms include loud-ish ticking sounds at idle, and driving
easy to spot...

open the hood and look at the bolts that hold the exhaust manifold to the heads.. typically it is the drivers side very last bolt to the rear that breaks first..2nd to last one to common as well.

Well I'LL BE DAMNED.!!!!!! Drivers side exhaust manifold bolt is broken, just like you said "last bolt to the rear". Any recommendations for a repairshop? I'm still trying to find one that is local. The local GM dealership said that they don't work on HUMMER's.

they are full of shi!t if they wont work on it.

take a look at the bolt..if your handy enough, you can take the header off and use vicegrips and remove.

another trick is if you have a welder.. tack weld a nut to the bolt, and try to remove it that way, just becareful of what your welding.

this should be a somewhat easy task for any shop really.. its just time consuming because they most likely have to remove the header and possibly disconnect the exhaust to it.

i think when i had mine done.. it was $200ish for 2 bolts, but it was warrantied

personally, if this happened to my H2 again, i would order some good quality bolts, and do it myself.
