Timing chain tensioner replacement - fix engine rattle
piked up the "revised" tensioner today from my local chevy(with the oil pressure slot). i'll be doing the job in a few days, myself, on my 2006 HHR..at the dealer, i spoke with one of the service guys who has done this job more than once.he said that the slot will "self-align" once oil pressure hits it....which i hope is right away upon starting the pup.......let us know how it turns out.........thanks.
Well, that was special ! first off for the terrified, if the old tensioner does come apart, I used a magnet to remove the spring and two other parts from the hole they lived in, nothing dropped into the engine, whew!! I looked at the Haynes book and ensured I had all the pieces shown in the exploded picture. the new part went right in, I torqued to the specified 55 ft/lbs and started the HHR no issues no more noise, ahhhh! success. there was a little bit of oil drip but not much. so have a paper towel or rag ready, I used my 32 mm socket, 24 inch Johnson bar, then torque wrench to set it at proper specs.
my '06 makes an odd "wheezing" sound (although I suspect it's mechanical and not vacuum based) at part throttle that goes away when I give it some boot .. I suspect it's timing chain tensioner ... will give a new one a shot to see if the noise goes away.
Very happy to see that it's less fussy than doing one on a 1998 VR6 GLi (engine removal makes it possible
)
cheers
