I'd rather be hiking, but the nice thing about the Cruiser is going out in those breaks between hazardous weather events and keeping close to the cab. The wipers work, and the sandy washboard was recently graded smooth. I had this site entirely to myself when I got there - El Camino Real de...

My understanding is that when the intake stroke compresses a smaller mass of air due to a barely open throttle plate, it burns slower than when the throttle is open and the compression stroke in squeezing a larger mass/volume of intake-charge. Increases in air pressure have a direct effect on...

My concern is corrosion. My original carbs drank mouse pee, and chased it with rain, melted snow, and some arid Southwest dew. Although you can blow these passages with compressed air, soak them in chemical dip, or run them with varnish removal that is in fuel injector cleaner, the...

A vulnerable part of the vacuum advance system are those tiny ball bearings in the sandwich that composes the breaker plate. I've seen them sooo rusted on my distributors, and the grease was caked with rust. If it is stuck the diaphragm can't perform vacuum advance. To rebuild it takes...

There is a torsion spring that maintains a closed-position on the secondary. Can it be unwrapped one turn, and will that change how much vacuum is needed to open the secondary butterfly?

That is the vacuum switching valve.

The wiring diagram has the starter's solenoid energized by the ACC-circuit. And the radio is wired thru the starter circuit.

So, are OEM Welch-plugs not like the core plug, which have a flare on the OD? I'd easily see myself getting confused by the subtle differences, particularly with the orientation or style of replacement parts. I put stuff on wrong all the time, and have to fix things. There is a Welch plug on...

We wove a wager into a tech-thread. Pump your fist with the 'like' button.

I just saw a guy run a smoke-machine thru an engine's oiling system to get a visual on any oil leaks, before any other work commences. So connect the 2F PVC system from the pcv valve to the valve cover. The smoke can also be applied in the cooling system. It was a real shop, with a dedicated...

Isn't there a dedicated plug installation tool somewhere? The video I found suggests that you drive it in from the circumference, not exactly a ball-peen on the center? Whatever.

My rocker assemblies on all my collection are shedding their brass, and it collects at the bottom of the catch-pan when I change the oil. These already worn-out parts have to last, because currently, this set of valve-train parts aren't available new. Iirc, Mark Jennings described rotating the...

I agree in a way. But, I don't recommend any oil to anyone. I'm only suggesting an oil. But, the flat-tappet cam issues went away a few years ago - this is because they changed their detergent to deal with low-speed-pre-ignition in turbo and modern engines. You don't literally need zddp in...

Because you just can't trust Toyota's factory literature? They are absolutely certain that above-spec. viscosity won't contribute to engine wear. From the supplier - Oil Viscosity Explained: 5w20 vs. 5w30 vs. 10w30 -...

The starter doesn't create enough manifold vacuum to risk exhaust-backfire?
