Knock, Knock, Whos There? Help!

I'd get after the previous owner for "selling' you that car with a faulty headgasket.
Noticed that he doesn't seem post here anymore....

I'm not too sure who put these headgaskets on. I was under the idea that these were stock headgaskets until I talked to my dad and he said they had been off before.

With this vehicle sitting 11 months out of the year, then me coming home for some r and r and beating on it, sure didn't help.

This car needs a lot of work and I'm aware. I'm pulling the motor and going to rebuild(as funds permit)

Luckily, I have this board to help me through my first rebuild.

The motor is ready to come out after the motor mounts, crossover, and transmission are disconnected.

Its possible that is graphite from the head gasket, make sure you drop the pan and inspect the pickup and clean out any debris. How was your oil pressure?

It was magnetic. Oil pressure was normal.

Rick Fernandez posted a video on his Facebook awhile back of his motor making the exact same sound mine was. He sent his motor to William Avilla. Tore the motor apart and found it to be the rod bearings.

In my little bit of reading trying to understand the bottom end. The rod bearings are the ones under the crank and the main bearings are the ones on top, correct?  If this is my issue, they should both be replaced, right?

It may not be as simple as just replacing some bearings.  The condition of the crankshaft bearing surfaces needs to be assessed and dimensions measured. Finding a reputable machine shop with experience in turbo Buick V6's can do this for you for a fee of course.

Where is the car now?

Im not underestimatin g the amount of work this motor is going to take. I already have a guy ready to check out the block, crank, pistons, etc. I was purely just curious if they were something you pulled out and set back in. I'm trying to learn as much as possible during this process as I see it as the best time to do so. ☺☺☺

if the bearings are bad, there is a very good chance that the crank will need to be resized and the rods also reworked....if you want to insure long long life...

the journals must be inspected and mic'ed to know how serious the problem is

[daveismissing]

Zimmerman's machineshop in Phoenix comes to mind as among the best.

What about this guy.

I think Zimmerman does most of Arizona GNs machine work. So either way your in good hands.

You are correct Larry.  Nick uses them for the machine work and then he and his son do the assembly

The OP said he has a GUY to look at the engine- not very inspiring unless he is experienced in Buick motors.

take it to a buick specialist like Nick and drop it off and wait. IMO.
