Julio, it looks like you have done a good job so far.  I have only painted one car in my life and I painted like I colored with crayons.  Not well at all.  they say Prep is 90% of the job.  I also figure having dry air in the hose is 90%.

General Buick Tech / Re: Which Size Rear Tires?

« on: November 09 2023, 09:03:39 PM »

For a car running 20 psi boost or more, the 28" tire will usually out run 26" tires (both with 3.42 gears).  Taller tire is faster out of the hole and generally on the top end as well depending on equivalent cams.  That is my experience.

On the other hand, 255 tires often run just as quickly as 275's on launch as the length of the patch is more important than the width.  Of course, if one has enuf more horsepower than usual, the width may contribute a little more.

The speedometer issue easy to resolve as a switch to a yellow gear brings it back in line.

Modern chips are not bothered by tire diameter as many of the factory functions have been disabled or ignored.

The problem comes with simply finding a tire in the desired size as 15s and 16s are basically obsolete in our tire ranges.

I went to 255s on my GN.  Went back to stock speedo gear.  It has 16" wheels.  My T has 15" rims and I am tired of the tire scuff.  I guess rolling the lips would fix that.  A lot of cars seem to have the axle offset a bit to one side or the other.  My GN did not scuff but it was really close.

Ok, I don't see anything. May need some 17" wheels. SMH

The 255-50s are a bit short I think. Getting hard to find 15s.  If they make a 255-55, that would be closer to a 26" diameter, I think

The original paints varied a lot in color and quality.  Most seemed to have brown in them.

This was very popular at one time.  I don't know if it has been replaced or not but it was gorgeous in my eyes.  Dupont code G9900S Super Jet Black

That's what I would do

I believe you could do that, but there should be a spring that prevents the plunger from moving until the back pressure gets to about 20 psi.  As I recall, the metal part is staked to keep it in position to hold the assembly in place.

I don't recognize those pieces.  You say that they fell out of the filter?

How long is that black piece?  I don't think I have ever seen anything like that in a filter being used as an anti drainback or bypass valve. 

It looks like the head of the black piece would fit into the metal piece which would close off "flow". But it would have had a spring that kept it closed normally

One other thing I thought about.  The plastic rod that goes down the shifter under the handle can be screwed in or out to change the height as I recall.  This might cause a bind in the button push if too long, I think. 

Of course, I may be thinking of another car LOL

Thinking about it, I would think the button should push in at any time so start by pulling the handle off and check the plunger and spring, etc.

My advice was aimed at the floor shifter.  The Park lever can bind up the shifter if not adjusted properly

« on: October 12 2023, 11:18:32 AM »

I have found it is a good idea to replace these on the lever that sticks out of the lower steering column where the rod from the transmission connects.  They wear out and get loose and then fall out with age.  Makes it hard to get the back up lights in sync with the shifter when it is in reverse.

NOTE:  It does not matter if your car is floor shifter or a column shifter, this bushing is still in use every time you move the shifter and it can make it hard to put the shifter into park as it can bind the linkage if missing or out of adjustment as well as get the back up lights to come on at the right time.

Assuming that you bought a cable that is an actual replacement (most aftermarket sellers are selling a cable meant for the 3 speed transmission-but a few of the Buick places are claiming their cables are the right length for the 4 speed transmission), then I guess it would not hurt disconnect it and see if the button on the transmission presses in and out as it should.

I am guessing that neutral on the column is not lined up with neutral on the shifter properly.  That is assuming the shifter cable is of the correct length.  Seems like this is one of the areas that not all of the aftermarket cables are the correct length?

Normally, you put the shift lever on the side of the transmission in to Neutral and then rotate the hub on the column to Neutral.  Then you adjust the rod from the transmission to the lever sticking out of the column at the firewall end under the hood until it fits without having to move the  shifter or the hub on the column to get it installed without moving the shifter or the hub any.   The hub is the piece that a column shifter would be mounted to if it was a column shifter was in the car.

With the rod adjusted correctly, the car should shift into park without resistance at one end of the throw and into Low gear at the other end.

Now if the new cable has an adjustment at the end that hooks to the floor shifter, I cannot remember.  I don't think I ever had to change a cable.  Maybe Jeremy or someone else knows that answer.  I just know that some have had a problem with the cables being the wrong length.

A side note is that it is usually after all these years to replace the bushing and sleeve at the bottom of the column as shown in the attached pic.  With wear or disintergratio n of these two parts, it gets more difficult to adjust the "Park" rod when adjusting the linkage.
