TTAC Commentator Nate writes:I’m working on a 1979 Dodge D200 with 360CID V8 4BBL carbureted engine, automatic trans, A.I.R. pump, EGR valve, and charcoal canister for the fuel tank hydrocarbons. The underhood factory decal says “California Medium Duty Emissions” and it has no catalytic converter from new. So here’s my situation:

• All hoses, pipes etc. are there and all valves etc. are working .
• The A.I.R. pump works but the diverter valve has failed (vacuum diaphragm leaks) and is in the open position so it’s always blowing fresh air into the exhaust manifolds.

Is it likely to pass the emissions test like this? I took my Ca. smog tester license training in 1984 and honestly only remember bits and pieces. So far I’ve not been able to find a new or good used diverter valve. Please advise!

Chrysler’s flathead (aka “L-head”) straight-six engine is one of the forgotten heroes of prewar and postwar Detroit, being produced from 1929 through some undefined year in the early 1970s (for stationary use, e.g., in generators and irrigation pumps). There was even a five-bank, 30-cylinder version made for tanks. It appears that it was possible to buy a new Dodge truck with the flathead six through the 1968 model year, though some say that Uncle Sam was the only buyer for the last few years of flathead Dodges. Most buyers opted for futuristic overhead-valve engines by the 1960s, anyway, but here’s a D-series pickup in a California wrecking yard that still has its L-head.

Since many Dodge D-series pickup parts fit my ’66 A100 van I’m always on the lookout for members of the species while visiting the junkyard. Today’s D100, which I found in a Denver self-service wrecking yard a couple of weeks back, is a little too new to offer many bits for my Dodge, but it’s still interesting enough for this series.

The Dodge Tradesman cargo van of the 1970s was quite popular among customizers back in the days of 20% annual inflation and talk-box guitar solos, as we saw with this ’72 Tradesman Junkyard Find last year. In the very same San Francisco Bay Area wrecking yard, here’s a Slant-6 Tradesman that doesn’t quite qualify as a custom van— not with just tinted glass and aftermarket wheels— but is still a nice time capsule.

After yesterday’s 1972 Dodge Tradesman van, we might as well stick with Dodge trucks of the Nixon Era for another day. Big simple pickups remain relevant long after their car counterparts get discarded, but sooner or later every 11-miles-per-gallon old work truck develops some expensive problem and becomes worth more as scrap than as a vehicle. This Dodge held on for 41 years before washing up in this San Francisco Bay Area self-service wrecking yard.

I’ve been finding quite a few vintage D-Series Dodge pickups in Denver-area self-service junkyards lately, which reminds me that I’ve spent too long ignoring Detroit pickups of the 1960s and 1970s in this series. I see them, but (unless an old truck has a GMC V6 and a bunch of ancient Deadhead stickers) I usually don’t photograph them. So, the Dodges: I shared this ’74 D-200 Club Cab and this ’73 D-100 Adventurer last week, and now we’ve got a ’68 Adventurer that shares quite a few components with my ’66 A-100 van.

Dodge’s D-Series trucks of the 1970s are still on the roads in large numbers, since there’s always someone who needs a simple work truck and doesn’t care if that truck is 10 or 40 years old. Still, you can always find another sturdy (if thirsty) Detroit pickup if something expensive breaks, so this Adventurer is now Crusher-bound.

You find some interesting historical documents in junked cars, and sometimes they’re glued to an engine’s valve cover.

The street-parked old cars I photograph in my Denver neighborhood live at one mile elevation, give or take a few feet. Drive about 100 miles southwest from here, however, and you’ll end up in Leadville, which stands at two miles above sea level. Last weekend, I ventured out to Leadville and found this painfully original 1947 Dodge brush fire truck parked downtown.

After the Fourmile Canyon Fire in September, charred vehicle carcasses began showing up in quantity in Denver wrecking yards. Completely burned-to-hell-and-gone vehicles don’t seem to offer any usable components for junkyard shoppers, but they still show up.
