The Day The BobD Died Again

Post by Amskeptic » Sat Apr 14, 2018 11:01 pm

( we'll take this from Itinerary Preparations and stick it in Type 2 04/20/18 )

So yes, the BobD princess puff punishes me haughtily. Our relationship has changed because of this affair I've been having with the slightly older heavier sloppier NaranjaWesty who at least still gets up in the morning without complaining*.

I tried to make amends to the BobD.
Shortened the exhaust pipe that got bent April 22, 2014, visiting cheesehead in the Washington metro area.
Remember how it jutted out?

OLD (June 2014)
Image


Not any more . . . me and Dremel did a very tricky multiple plane exhaust pipe truncatin' so it would discretely follow the horizontal contour of the bumper curve and follow the vertical tuck-in of the right rear quarter panel:

Image


Image


Replaced all the old plastic window chrome, yes, I did. Here's the ripped-out sliding door trim:

Image


Here is the "roll of chrome" waiting in a sink of hot soapy water:

Image

OLD
Image

Marked all chrome retainers so they wouldn't vary from the factory positions:

Image


NEW
Image


Got rid of that hated short windshield trim with the splice I have had to humiliatedly use since March 2014 when I got gypped by that Bug Haus guy from Connecticut. 2014:

(has done been continuing)
(today, I wasted more time to index the windshield's lower chrome trim cap to the exact center of the vehicle . . . this may be the only place in my life ever where anyone would almost have a passing interest in such arcana)

The chrome trim replacement may look better from ten feet or so, but any closer and you can tell it is "disturbed", and that:
a) makes me sad for this deteriorating world that inexorably tears things down and oxidizes them and corrodes them and breaks them down in countless ways, and the BobD now looks less than immaculate-though-shiny.
b) triggers my catastrophizing, the car is ruined! it looks like hell! F it! I don't care any more!

( I have subsequently fixed that pulled radius in the lower corner closest to the camera)

Image


This is a good distance to enjoy the view without little niggling critiques:

Image

But look at this! Look at this! There is nothing to be done! The trim cap doesn't know how to lay down on the new chrome profile! This is the sliding door window. One more moment where I have to retire not only my own standards, but lose the example of how beautifully these cars were originally put together:

Image


Now, the poor BobD has informed me that the honeymoon is indeed over. I have had a clacky hydraulic lifter begin to plague me at too many start-ups. So, at my first valve adjustment in three years, I decided to remove said lifter once I discovered which one was "soggy". Here is the 110,760 mile engine under the lower tin:

Image


Here is the heater valve dump tube, painted in 2011 outside of Fort Worth TX.

viewtopic.php?f=65&t=10045#p179583

That is primer plus clearcoat. Looks like the factory paint and is cheap and easy to execute, and heck, it has held up fine:

Image


110,000 miles of some pretty hot driving and all, and the head areas looked fine. This picture was taken minutes before my ten-year-long honeymoon was over:

Image



Yeah, party's over, right here:

Image


The above slightly blurry photograph shows #1 intake valve stem mushrooming. It means that the valve adjusting screw was not properly offset from dead-on center. The rocker arm needs a thrust washer to move it barely a half-millimeter to either side, but I fear that it is too late. THEN I thought to check the torques of the head nuts while the rockers were off. Dang again. One was at 12, another was 15 then 17 and a 20. Torque value is supposed to be 23. With torque values this low, there is a risk of distorting the heads by tightening only the lower ones. So, I decided to just do an easy zip up to 20 for all of them. Better than before, but not so much as to distort the heads too much. The engine needs to be torn down when I get a chance.

In the good news department, the hydraulic lifter "overhaul" was quick and it works like a charm now, that engine quieted down in seconds at first start. Lifter bottom (110,760 miles) looked pretty OK sort-of, if you ignore the caved-in bevel from outside to inside:

Image


Image


(put a towel over the lifter as you pry the circlip out, so it does not launch into low Earth orbit)
Image


Circlip, pushrod follower, lifter piston, lifter body:

Image


There is the spring that your screwdriver pushes against as you preload the lifter to 1 1/2 or 2 turns:

Image


THIS, this little ball was why my lifter was clacky. It wasn't sealing well under oil pressure. I filled the chamber with GumOut and pressed the ball against its little seat spring and let the GumOut drain through a few times:

Image


Cleaned everything very clean, filled the clean lifter body with some oil and stuck the clean spring in it:

Image

Image


The piston has a little chamber with a spring for that ball I was writing about. That chamber also serves to index the lifter spring. There are drain slots under the spring/ball and it all has to be clean:

Image


Oiled over the piston, pressed the ball under the oil with a well, test light probe, watched it drain down, and presto, the lifter has enough oil in it to pump up readily:

Image


Image


Pressed the ball with the electrical tester, pushed down on the piston, crammed a 2.5 mm allen wrench end in the lubrication hole to hold the piston down artificially against the spring. Stuck the lifter follower on the piston and snapped the circlip into its groove to hold it all together. Had to wrestle the allen wrench out of the hole.

Image


Stuck the lifter in, reassembled the rockers, adjusted the valves, and cleaned both valve covers shiny so I can keep an eye on any future broiling oil-come-coke deposits:

Image


After all of this, I thought the BobD was going to be "grateful" for a little love. And it was, all the way to WalMart and back and until the next morning.

Commiserations for your mushrooming. Were you able to get a look at the cam the the lifter bore?

1) Did you transcend space and time and install the trim without removing the windows? Or is that lubricant I see on the sliding door for reinstalling the windows into the car?

2) Can one use lash caps with hydraulic lifters to extend the stem life? (and maybe rocker pedestal spacers with them?)

3) I really enjoyed seeing the hydraulic lifter teardown! But your Kodak Easy Share isn't doing your pushrods any favors… :pirate:

Yes, I did not remove the windows. I could not have beared bore borne (something) the thought. I used the supplied little tool which worked like a charm so long as there was plenty of dishwashing liquid. Now the car foams up like a rabid dog in the presence of any water/rain/rinse:

Well, that is a great suggestion, Robbie.

I know, can you believe it? That Kodak EZ Share612 bent the damn push rod just by staring at it.
(and many many minds will be very very confused by this assertion, but there it is. :joker: )

Yay! An opportunity to chastise your incomplete understanding! *(phew!)

a) one badly behaved lifter cannot/does not indict an entire lubrication system.

b) the "increasing bleed down" should be read as "increasing number of instances" of clacky start-up.
This means that the lifter is bleeding down with the engine shut off. "bearing clearance oil pressure loss" Naw.

c) the actual cause of a clacky lifter upon start-up is just those occasions where the engine shuts off and stops rotating with that particular valve in an open state. All night, the 135-160# valve spring is trying to close the valve. The merest bit of varnish/speck o' crap at the ball/seat will allow the oil to leave the lifter. By morning, it is clack city.

d) NOW your question about "bearing clearance oil pressure loss" would come into play as the engine starts and builds oil pressure. Unfortunately, a cold engine has plenty of pressure and the viscosity of cold oil is hardly a obstacle in filling the lifter.

e) in conclusion, there are NO global engine lubrication/viscosity influences on any single lifter having a bad day. I go forth with a new understanding that anyone complaining of clacky lifters merely needs to remove and clean said lifters.

Re: The Day The BobD Died Again

So, as the title of this thread states, the BobD did die again, and here we are almost at Page 2.
My earlier post had stated that I tried to mollify my prissy little princess with tender ministrations like painting the wheels, yet it died in an intersection on its maiden trip.

This time, I was punished for replacing the window chrome trim, adjusting the valves, cleaning a lifter, re-torquing the lower head nuts, trimming the exhaust pipe, and replacing the finally failed EEC diaphragm that I had repaired on August 14, 2011(13,181) :

viewtopic.php?f=50&t=9952


Image

(easy repair second time through with a nice new diaphragm that has been waiting for about five years to have its moment):

Image


Trying to get a riot of Volkswagen reflections:

Image


Noted that the engine barely started. My fifteen year-old Optima Spiral Technology Battery that had refused to start the car up at the storage unit in Atlanta is clearly in the process of saying "ciao". Pulled it out, "thank-you Optima Spiral Technology Battery, but I hear that your offspring actually suck now."

Image


Installed NaranjaWesty's original never-been-used Die Hard battery that I had swapped out the day I first worked on it:

Image


See how the cars are pointing downhill? Me too. I installed the Die Hard with the notion that it would charge right up after a jump start. But, not even the idiot lights would glow, and I needed some electricity to get the alternator going. So, I used the Optima Spiral Technology Battery to juice up the Die Hard just enough to get the alternator excited. On my way to AutoZone to get some new Duralast battery for the BobD, I realize that the engine is dying as I approach stops and I have no tools, no tools.

Uh oh . . . the dead Die Hard battery is really really dead, and I have to keep the engine at a minimum of 2,500 rpm just to stay running. My little mtcamper commemorative Silty, The Autocrossed Alternator, is not putting out with a battery too dead to excite its windings. See a pretty good story here (7695):

viewtopic.php?f=68&t=12212&start=30

I had written, after that little emergency,
"Ridiculously, the utterly mangled pulley, the yanked and bent and beaten and viciously filed pulley, just spins away imperturbably back there, it has given the belt no grief in the past two thousand miles."

That pulley has gone an additional 7,260 miles and I had forgotten all about how utterly mangled that pulley was. Just checked the belt. It is fine.

Barely made it into the driveway at AutoZone. A dumb parking lot "after you- no, after you - no really, I insist" dropped my revs below even running the coil. Told the counter-person, "I'll make you deal. Give me a 13mm and 10mm wrench, and I will buy a battery." Thankfully, the engine started right up, alternator is belting it out, and I step on the clutch to engage reverse and get on with the day.
KaTONK! and the clutch pedal sags halfway to the floor.

Now, I am wizened with VW bus experience. I KNOW I have maybe two threads of clutch cable to work with to get home. I have maybe two emergency clutch dips before that cable lets go entirely . . . choose wisely.
Well, thank goodness I have a new battery, poor thing. Engine off, select 1st gear. Start in 1st and lunge out of the parking lot, grab 2nd by ear, grab 3rd by ear, release accelerator a bit and bunt into neutral to the first red light. Shut off the engine. Select 1st. Engage starter, lunge off to the next red light. Poor transaxle at least has good synchros. I had a lovely chance to blow through a triangular intersection with two sets of lights still on green, but alas, at the next intersection, some Zombie Cellphone Denizen just sat there and ruined my momentum. The trip up the steep driveway was the assigned emergency clutch dip as I killed the engine and entered the garage at six mph. Quick stop. Phew:

I could show you horror up close if you like. Have you ever watched the droplight with the spring-loaded electrical cord reel disengage from the roof gutter and rake its hook across the left quarter panel? Apparently, I have a real talent for rue.

Hello glasseye,

We've been missing you too. I and my Kodak EZ Share soldier on. We have both been losing function buttons. The Kodak no longer allows access to the menu, so I am on some unknown default. That applies to me too. We both can't see in the dark. We both have problems focusing. When I need a quick candid shot, it says, " . . . . what? Oh. You want a shot? Here?"

Amazing that it's still working and still viable. That's gotta be ten years old, right?

I must confess to forensically inspecting one image that has a reflection of you and the camera, just to see if you were persevering with that Kodak. Inconclusive results.

Still. Nothing wrong with any of your images. "Drive it 'til the floorboards rust through"

I'll be watching the dates on your Idaho Transit (which usually follows the Missoula Transit). Frito's always looking for an excuse.

Peter
