Boricua SS said:My love for my gmt is fading away... while cruising to the gym today, the beaSSt developed what we hope to be a top end knock... she knocks at idle, while parked, and the knock increases in rpm's... so back to the dealer she went... they already tore apart the top end as they believe its definetly in the heads.. more like a loose rocker... the crate motor only has 470 miles on it and I haven't even filled up the gas tank 2 times... she is completely stock all yhe way down to the paper air filter, I've followed the crate motor manual for break in procedures and I haven't taken her over 70mph... so I'm beyong pissed and fed up at this point.. I love my truck, but enough is enough...
The only reassuring thing so far is the service manager had an awd SS that had a crate motor put in at 44k miles and his knocked just like mine does now... his was a loose rocker, they fixed it, and now at 80k miles and a new owner (who lives by me btw) its running as strong as the first motor...so fingers crossed.. but in the mean time.. I think reality is here... its time to cut ties with the beaSSt...
Aparently, I spoke to soon!
