Hey! Were you able to track where the car came from? When I was 16 my parents bought me a new 1987 Grand National in Tampa, Florida. I kept it for 10 years and it had right around 100,000 miles when I sold it. Since it has over 100,000 miles I am just wondering by chance this one could have possible been mine at one point!
I was told by Pull A Part that it was turned into their Louisiana yard. I am not sure which one. There was some owner info in the glove box so email me and I can give you the details. classicgbodygarage@gmail.com
@@ClassicGBodyGarage 👍👍would be super cool if u did and highly appreciated. I just got a new core support and have no idea on how to change it. There's nothing on here on how to do it.

How are you doing there today? I got a 1986 Pontiac Grand Prix.it was my best friend Chris's car that passed away five years ago of a lifetime of diabetes and heart failure. It sat for 5 years and now it's mine... I've been trying to get it running again. but I'm pretty sure the motor has either a bad valve seal maybe a couple and or the rings.the murder was built by a local shop here in Pennsylvania. It was built for a circle track car stock car pretty much many many years ago. It has a 700 r4 that is lightly built and a stall converter it has headers neighbor hater exhaust. Lol All the goodies.

Since you started this. Now you need to bring it back to life all the way. With a full mechanical restoration, and cosmetic restoration. Hope you have money, you are going to need alot of it. To bring it back.
@@bren-xmotorsports55 oh no I'm sorry to hear that. But still a Grand National! I hope to run in to a deal like that. Well I cant wait to see the finish of the Buick keep up the great work

I bet the turbo is toast. Beware rebuilding/boring out these V6's. Could have pin holes in the cylinder that doesn't show up until it's bored out. That was my nightmare.
Love your videos but all you have to do is get some shop air and tread it into the spark plug hole then listen for where the air is going (carb,exhaust or radiator.

Why are you happy that the piston rings are the issue instead of valve seals? Piston ring replacement is much more labor intensive than ring replacement. Also you didn't mention how your going to fix the low compression, are you going to replace the rings?
Will pull the motor apart if I have to and replace rings and anything else needed. Will do it right, just want to see how well it runs as is. The rings could be stuck due to sitting and it may or may not get better.

Thanks!
Dude you're killing me with anticipation to see this thing run..... YOU CAN DO ITT.....!
haha thanks man! Next video soon!
Do you have a video for moving the broke electronic seat forward. I need help wit that.
No not yet but one of my cars has the same issue and haven't worked on it yet. The gear box is what usually breaks.
Good job Brian. Mne is about ready to fire up as well. Go man go!
Do you still have the Grand Prix? I like that one!
Sold all my GPs
Man we need them weekly vids from your golden channel bro 👍
One of my dream cars
Any videos on changing the radiator core support on a g body???
I can do one
@@ClassicGBodyGarage 👍👍would be super cool if u did and highly appreciated. I just got a new core support and have no idea on how to change it. There's nothing on here on how to do it.
Appreciate your videos is there anyway you could do a video of converting a limited slip over to posi traction
I can film a video once I have a rear to do the work on.
Oil seals on turbos are very often the weak link, Youre on the right track,
Great video keep em coming !,
I never thought I’d see the day
Looks like Bubba has been working his magic on your car.
Brian I cannot figure out my air vent fan shut off on high I got low medium but not high fan I bought a new switch and it did same same thing ??!!
Large red wire has a corroded plug most likely as that is a common issues or the high speed relay is bad
@@ClassicGBodyGaragethanks got new relay nothing but I sprayed wire with pb blaster and basinga 😂
When do you anticipate loading up Part 4? You're killing me with the gap in videos. Turbo shot? Head gasket? What's going on with this GN?
Soon. Its already filmed. Thanks for keeping up and the delays won't be long now.

When is part 4 going to be out?
Sometime this Spring.
Man I miss you videos good seeing you Brian mr gbody garage ftw
Thanks Chad!
Did you do a leak-down test on cyl 5 to see where the compression loss is coming from?
yeah and it seems like it is the piston rings.

surprised you didn't remove the downpipe flange and replace the gasket and inspect the turbo.
Downpipe donut gasket is fine. Turbo is tight, i checked it out. Seals might be going bad tho, will worry about that after i get her running right.
It's good to see you're still making videos on utube. I was starting to worrie thinking you where done with this. Good to have you back Brian👍🙏🙏🙏🙏🙏🙏🙏
😄 dude just gonna roll through the whole video without mentioning he been gone for a year😄. I like that. 💪. Hope the next video ain't a year from now👍
i thought about mentioning that but you all are doing a good job a it! LOL

I'd see about changing those coils out for new ones or for the newer style with 3 separate coils.
The rings may be stuck from sitting. I’d try soaking the pistons in marvel mystery oil for a few days then run sea foam through the engine.
What bore scope did you buy?
Its from DEPSTECH off Amazon.
any new updates?

How much do you want for it
Ill buy it
I live in illinois

or All the Above....
Thats next if needed
The piston would of been clean if it was a headgasket antifreeze would of cleaned all the carbon out im guessing burnt exhaust valve face
Is this car still for sale ?
car was never for sale
How much do you want for the car?
I don't own it. Pull A Part does

you'd rather have low compression due to worn piston rings than needing head work? why? heads are easier to fix.
Also, why put new plugs and wires on it when you have to yank the motor and re-ring it (at the minimum!)?
it doesn't sound like he is going to r-ring it.
why not see what happens as is then go from there.
it will get the work it needs
okay. I can't wait for the next video then lol.
