GM owner here – Great Site!

[Aaron]

Hey everyone (and Eric):

I’m a longtime DIYer and troubleshooter of GM cars, with some experience working on smaller Honda, Toyota, and VWs. I also road race at amateur level, so have a decent understanding of how parts wear and break, particularly with suspension and brakes. I’ve also put hundreds of thousands of miles on my daily driven cars, mostly doing my own maintenance and repairs. Hope to contribute and help other members with their problems if I can.

Of course, I arrived at EricTheCarGuy searching for info on diagnosing my own problem (I’m really stumped), and must say the initial reading is very thorough and well-thought-out. I’ve read through the Noises and Vibration Troubleshooting FAQ pages, and searched through many threads from users with similar issues too what I’m experiencing right now. Haven’t found the answers I’m looking for, so feel it’s time to post.

I understand basic posting rules in forums, and topic organization, so won’t go into my problem here in the Welcome thread. But before I start a new thread, what is the preference for posting structure here? If I find a thread with nearly the same issue I’m having, is it okay to resurrect the topic? If not, how about if the thread is more recent? Is this considered “thread-jacking”? Or, is it preferable to just start a brand new thread, just addressing my issue, among the dozens of other similar threads I’ve found using the Search feature?

Thanks in advance for any help I receive, and again, I’m looking forward to giving back when I can. Once again, great-looking and well-organized discussion board – see you around!

Welcome to the forum. 🙂 What I would suggest is start a new thread of your issue
and if you need to cut and paste a post that helps us understand your issue then
its not a problem. What we do frown upon is resurrecting a post that was not yours
and piggy back off it. It just makes it harder to re read the other post then start replying
to your post. It just keeps everything straight with a separate post. 🙂

Welcome. I notice a 455 car in your profile… I am an Oldsmobile guy too.. right on

@college man: Thanks for the info. I posted a new thread at this link:

@andrewbutton442: Yeah, GM products from that time were pretty hard to beat. It’s too bad how Oldsmobile lost its favor with the newer buying market. GM had to do it.

Here’s some info you might find interesting. I don’t think many know that the Olds 455 was blueprinted from the factory, with pistons matched to their cylinders in .0002″ increment groups! Read more in the linked PDF download:

Interesting reading on this great engine!

Interesting article. Joe Mondello is passed away now, but I actually caught him walking around at an Oldsmobile show Several decades ago. He didn’t want to be recognized (so I agreed to be quiet) but he agreed to sit in the Hurst Olds we were showing at time and we got a picture of him in it.. he was very friendly and recommended his port work. Oh fun times..The Olds motor I have been working on now is the forged crank larger bore 400 and its quite different then the later 4.25 stroke big olds motors.
