Sweet!

@  dezldave961 : (07 May 2020 - 04:14 PM)

Got bored and started making build video...

@  dezldave961 : (04 May 2020 - 04:05 AM)

I need to hunt down the little black trim bar that's at the top edge of the GS rocker panel cover, for driver's side between rear door and wheel well.

@  ejguillot : (03 May 2020 - 02:42 AM)

I've been on there too. I hope this forum is kept open, there's too much info to allow it to be lost!

@  dezldave961 : (24 April 2020 - 10:25 PM)

I've been monitoring GrandPrixForums and 3800Pro (don't have FB)... also hopped on TurboBuick, but 99% GN chatter from boomers

@  ejguillot : (19 April 2020 - 02:33 PM)

Everyone at home, plenty of free time.

Hope the new year is treating everyone well..

@  ejguillot : (16 December 2019 - 01:55 AM)

Hi all. Decade is coming to a close... I'm feeling a little old!

@  M_Dogg : (05 December 2019 - 11:20 PM)

Cheers!

@  ejguillot : (02 December 2019 - 01:13 AM)

Hi there. Some of us are working to keep these cars alive and running. Glad you had a good 15 year run.

@  opera_bob : (30 November 2019 - 08:39 AM)

Every time I see an Old Buick I have major respect for it. I know what kind of torque these cars make.

@  opera_bob : (30 November 2019 - 08:38 AM)

I sold my 2002 GS back in 2017. She was falling apart all over the place. So I sold her and bought a 2017 Focus RS in 2017.

2000 Buick Regal GS

At idle, there's a pretty obvious knocking sound, but once the rpms get anything over about 1k, the sound gets very feint almost to the point to where you can barely barely hear it. I've replaced the tensioner for the supercharger belt, and I've replaced the coupler inside the snout ready. I'm at a loss. I've been asking people and they keep saying it sounds like rod knock or piston slap. When they say that, I think to myself, wouldn't you be able to hear both of those all the way through the rpms? The closest video I could find with the same sound is this.. https://m.youtube.co...h?v=nIpIrwsn5pg

This is my daily, so I'm trying everything before I have to get rid of her.

In some cases the noise will not sound the same during different levels of the rpm speeds...this is because the oil flow and way the bearing could be damaged..a rod could float and create less noise....there is also the valves to look at if you are hearing a knock to ticking coming off the top end...a floating valve can get louder and more violent with rpms aswell...Bryan has the best idea....if you think it's a sc issue than remove the belt...the screw will still turn slightly but not at all at normal speeds....if you still hear the noise do a compression check...if you still have issues the only way to check for a floating valve or worn guides is to remove them.

Check into a cracked flexplate. Common problem and sounds like a bad bearing. Worse at isle, goes away with rpm. http://www.regalgs.o...ate#entry390405
