At 202K and having picked her up in the dark, the boots were a concern.
Looks like other than a rubber renewing my concerns were unfounded.

Heading out to do some linkage lube now.

TnBob · #18 02-28-2012, 04:48 PM

The hose in this picture looks like the overflow from the fuel filler recess that also acts like a water drain - so make sure there aren't any of those bloody pine needles in there too

As for the rubber boots - I'd clean them up first - just make sure they've still got oil in them.

Ive run a wire down from the filler cap and that line is clear.

There are a couple of missing exhaust hangers which will be replaced soon. Nicely enough as far as I could see from the rear bumper forward its all nice an dry under her.

With the help of a buddy got her running again today. Did a full diesel purge and was amazed that no bleeding was necessary after swapping the lines back to the fuel tank.

A couple vacuum leaks and linkage adjustments were pretty obvious. Also was the fact that the PO was not into adjusting valves. At least 2 act as if they have no gap left.

A lot more just general cleaning done, probably up to about 3 lbs of pine needles.

Dome and rear courtesy light now work. Sticky switches there. Most of the console switches are gonna have to be pulled and either fixed or replaced. How can someone screw up repairing such a simple switch ? PO got at least 3 of them.

All four windows roll up and down but several reeeally need a lube.

Brakes feel very good and are quiet while working. Rotors and pads all look like they have lots of miles to go.

TnBob · #24 03-12-2012, 02:22 AM

Valves adjusted well but #5 compression is still way down. Not gonna worry about that until Ive got some miles on her.

From the maintenance book it appears that up thru ~130k Castrol 20/50 was the only oil used. Probably take 2 gallons of kerosene to get all the munge out of the crankcase. At least none of the oil changes went more than 12k.

Got up close with the rear axles ... all boots look good. No doubt they will look much better once my rubber cleaner/protector gets here.

Some one actually lubed the accelerator linkages as Ive found no dry ones.

Both my 3/2 vacuum switches work.

Even the fog lights work.

TnBob · #26 03-13-2012, 09:32 PM

Ohh curses... the door locks dont work automatically !

I included a couple of under the hood shots.
Vacuum at the 'white' line was ~23 inches.

Shutting down is no issue so the 'brown' vacuum circuit is fine.

Neither yellow line would hold vacuum.

In front of the drivers seat with the carpet up and the plastic line cover up the lines are all easy to see. I just used a hammer to prop the carpet up.

Green is supply, red is return.

Both gauge reading pics were taken after holding for a couple minutes.
They both were from the drivers side circuit. The resize pretty well wiped out the readings but both are right at 25" after being pumped up with my Mityvac, an invaluable tool for chasing vacuum issues.

The issue is on the passenger side. Neither supply nor return will hold vacuum.

If you don't want to replace the weatherstripping just yet, there is a trick I got years ago from Hot Rod ........ find where the leaks are - probably some chunks missing - get a Windex - type spray bottle with water in it, some kitchen plastic wrap, and a tube of automotive black silicone sealer. Clean any crumbly rubber from the weatherstrip, apply an adequate amount amount of black silicone, spray both sides of the plastic wrap with water, drape it over the blob of silicone, and close the door. Allow to set overnight - trim if necessary. I got rid of a couple of whistles on a 79 Pontiac wagon this way, and the repair lasted the 4 years I drove the car.

So what's your next step going to be then?

TnBob · #29 03-14-2012, 11:26 PM

estod... thats a good one. Not sure yet but Im thinking resetting and replacing the door strikers may have done that.

Army. Probably gonna pop the trunk fuel tank cover and silicon or epoxy that vacuum accumulator inlet. Fuel gauge is fubar so ya know whats gotta be done there.

TnBob · #30 03-26-2012, 11:04 PM

More and more works as I add miles. Actually had my 1st and hopefully last breakdown in my driveway. The tranny control shift rod popped out free and I had no ability to shift.

Pulled and measured the bracket to find it takes a 5/8's OD bushing. Trip to the auto store got one with tax for bout $2 with several others. Much better than the $5 per part plus $5 for shipping on line.

As long as life doesnt get in the way the console switches will get rebuilt tomorrow. I do plan on pics as the switches are a piece of cake to get working right.

The 12 year vacation is over and she is responding nicely. A pedal to the floor start on a long clear stretch netted me maybe 30 feet of black smoke that you could actually see thru. The first couple were like a tin can laying down a smoke screen.

Another cute one ... the PO had the primary fuel filter in backwards. Grrrr

Coming up on a full fluid change. Added MM oil and ATF to the crankcase, Startron to the fuel tank. Trans from a fresh start at times simply doesnt want to do anything for about 2 minutes. Going down to low has gotten it working and as it shifts very smoothly thru the full range its not something Im gonna be concerned with until after a full fluid change which includes the torque converter.

Got a buddy helping me who has years of diesel experience which sure helps my learning curve too !!
