kirks5oh Posted April 7, 2011 Report Share Posted April 7, 2011 guys, have to report a negative experience with haydocy---3 years after the fact background--- bought '05 GTO in 2007 with 11k miles on it. took it to haydocy for several minor issues under warranty and was happy. took it there in late 2008 with 15k miles on the clock to fix a leaky rear transmission seal. they told me the car also had a rear main leak (minimal leak, but i knew it was there). they told me they could fix both under warranty, and did so. about a year later and the rear main is leaking again no big deal, its just a tiny leak. i drive the car for 2 more years and currently it has 26k miles. right before i put the car down for the winter, i noticed a small rattle under the car that occured when starting from a stopped position (figured it was a loose exhaust shield). i just started driving the car again, and noticed the noise again. got the car up on my lift and found that one of the flange joints on the midpipe was missing two bolts that form a compression joint and hold the midpipe together. that is, one side of the midpipe is formed of two pieces for some reason. a downstream pipe slips into the upstream pipe and is compressed by a flange and a mesh gasket. this was definitely in place when i bought the car, because i installed a catback and noticed this joint and the bolts. it definitely had to be removed when haydocy did the work, and was definitely NOT reinstalled correctly---so i've been driving the car that way for 3 years---wtf? its not bad enough to have an exhaust leak--because the downstream pipe is fairly snug inside the upstream one. it definitely needs fixed, and i'm sure these bolts are going to be dealership pieces---maybe i'll call haydocy and see if they have my fucking bolts laying around. i still have the work order, maybe i'll ask to talk to the tech who worked on my car. frustrating, the lack of attention to detail. and before anyone asks, these bolts are screwed into a 3/8" thick metal flange joint---there's no way they would back out on their own--anyone who's removed bolts from thick exhaust flanges know how much of a bitch these can be to remove. add to that the fact that all the threads in the flange have oxidation on them proves the bolts have been missing forever Quote Link to comment Share on other sites More sharing options...
Cordell Posted April 7, 2011 Report Share Posted April 7, 2011 Sucks to hear, I had a Tahoe a few months ago that some dumb tech put cats on under warranty. Then comes in to my dealership about a year after the fact with an exhaust leak complaint, still under warranty. Fucker had snapped off 2 of the manifold to converter studs, so I got take the manifold off the truck and replace the studs. Just goes to show that there are hacks on all levels. Sorry to hear about your unfortunate run in with a worthless tech. Quote Link to comment Share on other sites More sharing options...
kirks5oh Posted April 7, 2011 Author Report Share Posted April 7, 2011 should be easy to fix. just a hassle to track down the part. helps having a lift. i remember when i had it fixed i also suspected the car had been driven as well.

kirks5oh Posted April 7, 2011 Author Report Share Posted April 7, 2011 just called the stealership---they don't service the midpipe--it would have to be replaced $1300 time to go to lowe's and try to track down a bolt to fit the flange. thanks haydocy.
