hi i just bought an h3 2 weeks ago.i just noticed a rattle at start up. but then it kind slowly goes away after a few minutes.the h3 is an 06 with 40k miles on it. i hope this isn't the head valve issue i have been reading about.any suggestions on what it could be? it ony rattles at start up

 

took it to dealer it was a leak in exhaust manifold. in process of installing new one as i type

 

WELL THE DEALER BROKE A BOLT WHEN TAKING OFF MANIFOLD. NOW I GET A NEW HEAD ALSO. YIPEE I GUESS??

 

Glad they figured it out.

 

THNX i tried looking at ur pictures but they wouldnt show up. just got the jpg logo and blank square

 

WELL I HEARD A RATTLE AGAIN THIS TIME IT'S #2 CYLINDER STICKING. AND HOLDING EXHAUST VALVE OPEN. SO THEY SAY WE WILL SEE
I BOUGHT THIS HUMMER LAST MONTH BEEN IN SHOP FOR 3 WEEKS. I FEEL LIKE A SUCKER
