Re: Itinerant Air-Cooled Greetings From Seattle

Hit the road hard towards Seattle from the FAIL rear window repair/repaint.
This was my 3,000 mile oil change spot. Bored people had shot up all the trash in this abandoned semi-quarry many many times over. The child's bicycle with tassles on the handlebars was particularly fraught with an unsettling energy as I looked at the bullet holes in the chain guard and the seat. Old oil looked fine, exhaust studs were mostly OK, valves were a little tighter than I wanted:

Image


This remarkable view caught me by surprise again. It just rushes up in the middle of Interstate 90's traverse of this expansive dry landscape:

Image

Image


Saw this through an unexpectedly moisture-laden atmosphere. That is Mount Ranier from the inland side. Seattle is yonder past the volcano:

Image


Image


I photographed these two big concrete barrels straddling the interstate a few years ago.
"What are they," I had asked at the time, "new friggen toll booths?"
"A wildlife crossing," I had been told, "see, moose and mountain lions and deer and field mice will all traipse over the bustling interstate."
It did not seem likely to me. Still doesn't:

You know Seattle is coming up when you see these craggy-azz mountains pop up. Snowqualmie Pass. At least this year was tolerably warm:

Image


Image


It is a more serious descent into the metro-Seattle area than you might expect, because you are also coming off the continental plateau at around 2,500 feet across the heart of Washington from the western Rockies to the Cascades ... (save me, Mitch, I think I'm slipping):

Image


Anyways, I found Ronin10 the next morning after camping next to a dead homeless man behind a Korean accounting firm next to the demolished apartment building on the hill (just before I placed a call to the coroner, the dead man roused unhappily to greet the overpowering sun).

We were to investigate an oil leak at the bell housing. The bell housing was definitely wet, but the flywheel and pressure plate looked pretty dry. Thus, Ronin10 and I made an executive decision to remove the threaded gallery plugs. Good thing:

Image


We carefully cleaned the threads and JB Welded those suckers back in, then carefully reassembled the main seal (wood chips, Andrew, wood chips) and flywheel/clutch.

Image


I await a report with bated breath. Found a failed helicoil on the transaxle where the Bowden Tube bracket bolts up. This is a heavily worked bracket, lots of twisting force when you step on the clutch pedal. We made it a priority to do a good job taking out the helicoil strand, drilling the transaxle for a big bolt .. .. .. :

Image

.. .. .. drilling the Bowden Tube bracket for a new big 12mm short bolt (it was a pleasure to see Ronin10 approach this task with an engineer's sensitivity to the physics of torque and an artist's sensitivity to finishing the hole smooth):

Image

.. .. .. and trying to face the transaxle for a flat washer to shim between it and the bracket (which I did a damn fine terrible job of)(not to mention my mangled grammar), then foraging for a flat washer to shim between it and the bracket:

Image


Somewhere around the end of the day, we had the engine and transaxle back in, and I uncharacteristically bailed out of there! before the engine start! leaving Ronin10 stranded! to complete the job! so he could go to work in the morning!

Image


What is up with that? Well, I am old now. I get exhausted more easily. The sun was unexpectedly strong. And my priority this year was to sit and have a beer with my customer while we looked at the uncompleted Volkswagen task in the evening light:

I know nothing about these wood chips you speak of. Really. Not a thing. Nope.

I finally got the engine back together and out for a test drive around 1am. My muffler with its too long studs gave me fits and sucked up about an hour all on its own. Everything ran great! One of the things Colin didn't mention was replacing the bushings on my shift rod after he talked me out of making the VW recommended modification to add an additional bushing to the shift rod. I didn't have either a witty or thoughtful retort to fall on so I went along with his recommendation. Once I got my shifter adjusted, everything is running great.

The leaks between the bell housing and engine are non existent, but it has highlighted another source. I can't say for certain, but it looks like either the seal around my oil pressure relief valve isn't doing its job or it may be higher up from the oil cooler mounting itself or perhaps the filter bracket. Either way, fewer leaks is better. I'll claim victory with the progress and try to eliminate the other source before Colin arrives next year.

The bowden tube bracket dremel job was indeed a little less than stellar, but functional nonetheless and that's most important when your bus is your daily driver. However, I think that can be remedied down the line with a jig and better tooling.

As always, it's a great to have a second set of hands, particularly when they're as knowledgeable as Colin.

Well, I feel sort of better, glad you prevailed. Wood chips? I must have been dreaming ...

Check distributor o-ring (oil pooling at base of distributor) and breather cork gasket!
