#2657: Getting to Yes

High viscosity oil is thicker oil that flows less easily, especially when it’s cold. That’s why the speaker argues it can be “a bad thing” for cold starts—thicker oil can increase engine wear until it warms and circulates properly.

Overdrive is a higher gear (or gear mode) in an automatic transmission that reduces engine RPM at cruising speeds. The speaker says the car “kicks into overdrive” around 40–50 mph, which is why it can then go faster without the engine spinning as hard.

The Prizm (often spelled “Geo Prizm”) is a compact car known for being practical and straightforward transportation. In the podcast context, it’s being referenced as another car in the same household or comparison, with a 1995 Geo Prizm mentioned alongside a Ford Explorer. It comes up because the conversation is about how these cars behave day to day—especially what happens while driving.

Fuel injection is a system that meters fuel into the engine using electronic controls rather than relying on a carburetor. The speaker contrasts modern fuel-injected cars with older carbureted setups, noting that fuel injection reduces the risk of over-fueling during warm-up.

A choke is a carburetor cold-start device that enriches the air-fuel mixture so a cold engine can start and idle. The speaker explains that with a choke, the engine can rev high (around 4,000 RPM), which wastes gasoline and can stress the engine if left uncontrolled.

A carburetor mixes air and fuel mechanically, and it often needs a choke for cold starts. The speaker uses it to explain why older cars could waste fuel and potentially cause engine damage if you keep the choke on and let the engine rev too high.

The “Beetle” refers to Volkswagen’s iconic rear-engine compact, the Volkswagen Beetle. In the early 2000s and beyond, “new Beetle” commonly meant the modernized Beetle that revived the original’s styling cues.

The “micro bus” is a reference to Volkswagen’s classic Type 2 “Bus” (often called the Microbus in enthusiast talk). It’s known for its boxy shape and passenger-carrying heritage, and later “new” versions revived that identity for modern buyers.

A backfire is an ignition event that happens in the exhaust system rather than inside the engine cylinders. In this case, the host ties it to missing ignition spark, so unburned fuel/air ignites in the muffler and exits through the tailpipe as flames.

Ignition refers to the system that creates the spark to ignite the air/fuel mixture in the engine. The host says the ignition is missing in all likelihood, meaning not every cylinder is getting a spark when it should.

Ignition points are mechanical contacts used in older ignition systems to control when the ignition coil charges and fires. The host suggests the most likely cause is that the points are burned up, which would lead to weak or missing spark and misfire/backfire.

A condenser (in classic ignition systems) is a capacitor that helps control the electrical behavior of the ignition points and coil. The host indicates the condenser may be the missing replacement, implying it could be failing and causing poor spark.

A distributor is an ignition-system component used on many older engines to route high voltage from the ignition coil to the correct spark plug. The speaker describes removing it because a plastic piece is supposed to go into a hole at the bottom of the distributor, and if it breaks or falls in, it can cause an electrical short.

“Shorts out” means an unintended electrical connection creates a low-resistance path, causing current to flow where it shouldn’t. In ignition systems, a short can prevent the engine from running by disrupting proper high-voltage operation.

The Volkswagen Karmann Ghia is a classic Volkswagen sports coupe known for its distinctive, stylish body shape. It’s often discussed in enthusiast circles because it represents a simpler, more design-focused era of small cars. In the podcast, it’s mentioned in a playful way around “making” a new version, which highlights how memorable the name and design are to fans.

The Isuzu Impulse is a compact Japanese coupe from Isuzu, known for its unusual styling and for being a bit of an enthusiast oddball. In this call, Sarah mentions it specifically because sourcing parts has been difficult for her model.

An “impulse purchase” is a buying decision made quickly, without much planning or research. In the segment, the host uses the phrase as a pun because the caller’s car is an Isuzu Impulse.

A “two-seater, two-door” describes a body style with seating for two people and two doors for entry. It’s a quick way to communicate the car’s layout and packaging, which matters for things like interior space and parts availability.

Weather stripping is the rubber or foam seal that lines the perimeter of a car door to keep water, wind, and noise out. When it freezes, it can make the door harder to open or keep it from closing properly.

Silicone spray is a lubricant/protectant used on rubber seals and weather stripping to reduce sticking and help them resist moisture. In cold conditions, it can help prevent seals from freezing to the body or door frame.

The door latch is the mechanism that engages when you close the door, holding it shut and allowing it to be opened with the handle. If the latch is frozen or gummed up by water, it may not “latch” again after being forced open.

A latch mechanism is the set of linkages and parts that physically hold a door closed and release it when you pull the handle. When moisture gets in and freezes, the latch can bind, preventing the door or window from operating normally.

Power windows are door windows that move using electric motors and a switch instead of manual cranks. If the window regulator or related hardware is exposed to freezing moisture, the window may not operate even though the motor is working.

White lithium grease is a thick, tacky lubricant commonly used on metal-to-metal moving parts. In this context, it’s meant to coat the latch mechanism so water can’t reach the surfaces that would otherwise freeze and bind.

The Ford Explorer is a body-on-road SUV known for being used as a daily driver and family hauler, so unusual noises under the hood are a big deal. In this segment, the 1995 Ford Explorer is described as making a loud “French horn”-like tone at idle, which points to an engine-bay issue that only shows up when the engine isn’t revving.

A “93 Civic” refers to a 1993 Honda Civic, a compact car known for being practical and easy to live with. In this story, it’s the specific car Jane is describing when she hears a loud knocking noise from the back/trunk area.

The trunk is the rear storage compartment of a car, typically accessed from inside the cabin or via an exterior latch. In this story, the knocking seems to come from the trunk area, which is why the owner suspects something is loose or trapped back there.

A shock absorber (often shortened to “shock”) controls how quickly the suspension moves after hitting bumps or changing road load. A “loose shock theory” suggests the noise could come from a shock mount, bushing, or fastener that’s not secure, allowing the shock to move and knock.

A sway bar (also called an anti-roll bar) helps reduce body roll when the car turns or when weight shifts. The “sway bar theory” here means the noise could be caused by a worn bushing, link, or bar-related suspension movement rather than the exhaust.

A coil spring is the suspension spring that supports the car’s weight and controls ride height and movement. A “broken coil spring” can cause sudden clunks or booms because the suspension can’t compress and rebound smoothly, and the spring may shift or contact other parts.
