Today while an eclipse occurred, I took my driveline apart.

I replaced the diff pinion oil seal.

Now, dirty but dry. It has a pending date with the pressure washer.

Through my welding hat

[PhilA]

Cleaned up underneath a bit.

Need to wipe that all down and put some paint on.

[PhilA]

There, that's a little better. Will be able to see better if it's leaking now.

[PhilA]

Cleaned up the governor receiver, drilled out the pin for the reverse lockout. Both pistons were stuck with age. 

Replaced the pin and crimped it down.

Changed the piece out and... No, it's still doing the same. I need to recheck the ports in the case for blockage or leaks.

Patience of a.saint (y'all)

[PhilA]

Cleaned up. Tomorrow it's an exhibit at the Rougarou Festival in town.

Went full up the tank, so I don't have to bother in the morning.

Still looks good all clean.

Milkshakes obtained on the way home.

A misty Louisiana morning turned into quite the scorcher.

In spite of that the turnout was good.

Just a little more rake than I would like, to be honest.

GASSSSSSERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR

They ain't Oreos, so don't be eating them.

$62 later and I've got new tires put on. That'll do.

They ride nicely too. Much better.

It's that season again. Big fart of cold air come in from up north, we've gone from a balmy 27° to 6°. Belt would screech briefly pulling away from a standstill so a bit of this gunk on it shut it up nicely.

Heater has been pressed into service, works well. Just did a 40 mile round trip to collect the kids and friends and drop them all to their respective houses. Toasty warm.

Had some errands to run. So the car visited one of its favorite places.

Went check on a few things at the building site. 

Then, stopped to pick up dinner at a little local place to grab dinner.

Pleasant evening for a drive!

Two Pontiac cars, both daily drivers, in one photo.

Rare sight!

Oh no you bought a fiero

[Madman Of The People]

 

Aftermarket spoiler fail on that Fiero!

Hard to believe there's still a daily-driven Fiero in the wild.  I thought they had all either burst into flames or been turned into bad Ferrari replicas decades ago!

 

[PhilA]

Day off today, the whim took me and I drove old highway 1 to where the road stops.

That's desolate now. That road used to be 24/7 busy traffic, the town was a busy little place. Now it looks like a Mad Max movie set.

For reasons beyond my control, I ended up in town today and braved Christmas traffic.

That was potentially a good thing because the gearbox did something weird it's never done before, which shed light on the fault of the 1-3.......4 shift thing it does when it gets hot.

The drive home was pleasant. The car was running perfectly. Quiet, smooth, luxury. That gave me chance to think so when I got home I broke out the gearbox service manual, then went take apart the spare valve block.

Turns out the 1-2 throttle valve appears to be a bit of a kludge and as such has a bit of bad engineering occuring. A sharp 90 degree edge was machined on the edge of the idle drain plug, which should be sitting in a bore with a port, but instead sits between two sections of the casting with holes drilled in.

As the spring that pushes against heats up it seems to compress in an arc rather than straight down, applying a small radial force to the plug, pushing it off center because it's worn (we're talking maybe a thousandth of an inch) and causes it to jam solid halfway down it's travel, which blocks the 1-2 shuttle valve from moving fully.

So, I machined a chamfer to overcome their faux pas. Applying a side load to that now isn't a problem, it self centers and moves properly.

 

If circumstances allow I'll fit it tomorrow.

Fortunately, unlike Archimedes, PhilA was not in the bath when he had his "eureka !" moment.

(Hope it fixes the issue).

phil 1 car 0 maybe

 

[PhilA]

Swapped valve blocks. Back on the original with the revised piston.

 

So far, it works. But I'll have to see how it behaves once it's hot in traffic.

[hairnet]

stop taking it into town

 

[PhilA]

It's a car, it gets driven wherever.

 

Took it for a drive and got it warm. Result, under very light throttle it still hangs up, but under moderate (average away from the lights) acceleration it changes perfectly.

I think that chamfer needs to be reprofiled to be a gentler curve rather than a 45°, polished. It should then slip in easily with the miniscule forces it would appear are present at light throttle.
