Re: What did you do to your truck today.The 3rd chapter
I got my '71 GMC Jimmy back on the road in the wee small hours...
Had to call Roadside Rescue Monday night to get a guy with a jumper box. Got home at midnight. Back at work at 8:30 in the '68 Orange Stepside. I had left my lights on, parked Downtown on Monday, while I was at work nearby from 12:30 to 10:30 PM. Four 5.5'' sealed beams at full blast. After work, I tried the key. Nothing. Dead flat. Wednesday I got off early enough to drop off the Batt, a 4-y.-o. Deka at O'RAP. A DVM reading w/o load was 12.63 vdc. Parts store found no faults, and charged it overnight. [For free]. Stopped by Thursday and picked it up. Charged full. While I was down, I checked the oil. It was low 1 Qt. Added one. Good catch. Reinstalled and it cranked up good. Ran to grocery store today. Nominal operations resume. :gmc2: |

Re: What did you do to your truck today.The 3rd chapter
Started last night and will continue for a few days to come. Pulled the intake last night to fix a nagging and worsening oil leak on the front.
Decided to check the timing chain play before I pulled the distributor. Found that to be more than I like but not a total surprise. So, today I will drop the oil pan slightly to get the timing set out. New water pump and timing set should be here Monday. Meantime I will clean up the heads and intake for re-install. The little mouse motor (283) runs fine and I hope to get another year or so out of it while I save my penny’s for something else. |

Took the '68 C/10 Stepside [292 L6/SM465/3.73 REAR] into AZ ADEQ [emissions]
today. It passed. Readings: HC ] Hydrocarbons/PPM.....093 OF 450 allowed CO] Carbon Monoxide %......1.82 of 5.00 maximun |
Re: What did you do to your truck today.The 3rd chapter
Pretty much any vehicle engine in decent shape will pass the emissions test. I worked as a state-licensed SMOG tech for years. People used to come in all concerned that they wouldn't pass. If they didn't, it was generally timing or carb adjustments, and I'd make those adjustments as required for the $25 test fee. I generally didn't even tell them I did it, just handed them the cert. Didn't take that long, and I didn't feel like charging an extra $50 (or whatever it was) for the amount of time those adjustments took. Missing equipment was a bigger deal, but those I bucked up the food chain to the BAR as required. Very seldom did a vehicle fail, really.

For $12.25 you get a second retest free. My Buddy/Mechanic, Dennis would open up the Edelbrock 1404, and we'd trade out the normal running jets and metering rods, for a special set in a ziplock bag marked ''Economy'' and I 'd run thru the retest. After passing, we'd reinstall the Normal set. I would usually do as much of a tune up as needed -- Dist Cap, Plugs, Wires, Air Cleaner, whatever else... V8s were the worst to get thru. The '67 K/10 Suburban w/454 has been sitting for years. The '71 Jimmy's 350 was often a Bad Boy too, but since I got YOM plates and collector car insurance, it's exempt. L6s generally are ''Nice Kids'' to the ADEQ guys, but my 292 is bored .030-over, has a 4-bbl Edelbrock [500 CFM] Offy intake, and Clifford headers. Anyway, year before last, I left the Economy jets and metering rods in the carb, and didn't change them out. Last year, I passed on the first try. Just like this year. But while I was at the emission station, I noticed my water temp get really hot. It was up past 225*F -- didn't boil over due to a 50/50 coolant mix. [Boil-over is an immediate 'Flunk'] but I had to gradually raise my RPMs after the probes were pulled but before I got my paperwork cert. Pulling out of the facility, I cut on the Heater Air fan and Defroster to bring the engine temps down. It was in the high 90s today in Tucson. As soon as the temp gauge came back to 195* I saved the Heater etc. Engine cooled down on the way home. I asked Dennis about this, and he said I'm set too lean, and to back off the A/F mixture screws til I get a nominal 17.5''Hg on the Manifold Vacuum gauge. :chevy: |
Re: What did you do to your truck today.The 3rd chapter
There's plenty of money to be made in the mechanic business without stealing it. When I worked as a mechanic, the BAR's newsletters claimed that half of all repairs in California were not necessary- not just emission controls. That's probably still true. I didn't tell the boss what I did, though. He'd have gotten all soggy and hard to light. But by the time all the equipment is hooked up for the test, 3 more minutes tops for needed adjustments didn't justify the extra charge, to me.

Lots of crap on the 72 . First redid all the rubber lines they were real bad ended up buying them from Brake Hoses unlimited . Fit was perfect as apposed to the two other sets I bought and returned to other venders . New power vac and master only thing I had to modify the combo valve bracket to fit the original lines didn’t line up at all I had to straighten and then re-bend it I wasn’t going to change perfectly good originals . Brakes all done and bled next was the Flexplate the old one had a a few missing teeth . I took out the driveshaft and removed the crossmember bolts to the frame and replaced 4 bolts with 10 inchers and slide the trans back . Tomorrow I hope to have it buttoned up and drivable again .

Re: What did you do to your truck today.The 3rd chapter
72c20customcamper longer bolts is how I use to do it in the garage thru the years I wrenched for a livin. I used the long bolts to make installs easier as well.

Re: What did you do to your truck today.The 3rd chapter
Finally got the steering gear back together. Shiny new idler arm, Pitman arm, and some 90* Zerks on the inner tie rods(cuz that's a really crappy spot for straight Zerks).
I got close Tuesday, but was fighting nausea(vertigo?) and had to give up early. Far more pleasant all around today |
