I took turbo off and the loosened the plate/shield on p/s, it has 2 studded bolts just loosened the nuts enough to give room to get injector rail off

It can be hard to pull the turbo out of the intake manifold. Be careful with the o ring on the adapter. Also make sure to lube the o ring when u go to install the turbo again. Its hard to get it seated completely, really have to look at where the adapter goes into the intake to make sure its seated properly.

Got all the bolts out and the flex hose out and took off the down pipe nuts off and the nut that holds it in place with the eye slot that allows you to slide it out what else is holding it besides the oil drain ?

 

[bpman1234]

Also should I remove it with the tb on it ?

 

[gsbuick65]

I used a crow bar stuck between the turbo & intake put pressure on turbo and wiggled it, i took tb off

Ok thanks gonna go finish .

 

[bpman1234]

Ok the only thing holding it down now is the drain to return is it easier to unscrew it from the intake or from the turbo

 

[bpman1234]

Rain got me . Hate stopping in the middle but Time to do some something inside thanks for those that chimed in also that oring gasket that goes to the down pipe can I get that at the plain old auto store or where ?

The oil drain should just pull out of the intake gromet.

I would unbolt the throttle body as well.

The downpipe gasket, i dont remember if its reuseable metal. I know i didnt replace mine.

Becareful with the exhaust elbow bolts,theyre easy to break.

 

[bpman1234]

Yeah took of the throttlebody off laid it to the side the only thing that is holding it there will be there on the drain ?so I should just be able to pull it right out?

Yeah but its hard to pull the turbo up off the intake because that oring. If you have a pry bar it might help prying it off the intake.

 

[Boost231]

Make sure it's unbolted from the intake bracket on the passenger side a well. The turbo has a y bracket on it which is bolted to a plate that's bolted to the intake. The oil drain can be left on and pulled out with the turbo. I would leave the throttle body on as it's easier to lift it out when it's bolted on.

Ok thanks yea got them bolts at the back its moving freely but have to get more lift using the pry bar rain stopped me from going farther

 

[Boost231]

I just rock it back and forth using the throttle body as leverage while pulling or prying up

Hey I may have never worked on a Buick T or GN but I have bloodied a knuckle or two in my decades of being my own mechanic. If you are in no rush spray down those bolts/nuts with WD40 or brake cleaner, re-apply once or twice, and take your time but do NOT strip a bolt/nut. Have fun and learn and you will then be able to play "roadside mechanic" and almost never get stranded.

I need to expand my tool selection and play "traveling mechanic".

Yea have a spare of almost all that I may need for my 87 maf coil module cam sensor and the tools to do the jobs call me crazy but you never know . Test light volt meter fuses .
