Q how to paint engine block without removing engine

While it’s always best to remove the engine from the car to paint it, if that isn’t a reasonable option for you, follow these steps: 1. Prepare the Area: Cover the car parts around the engine with plastic sheet or cloth to protect them from the paint. 2. Clean the Engine: Using an engine cleaner or a degreaser, clean the engine block thoroughly. Get rid of all the oil, grease and dirt. After this, clean it again with soap and water if needed. 3. Abrade the Surface: Use sandpaper to slightly abrade the block. This will help the paint adhere to the surface better. Only expose the metal; be careful not to cause any significant damage. 4. Apply Primer: Once the engine is dry, apply a primer. Use a primer that is resistant to high temperatures, as the engine block gets hot when the car is running. Follow the instructions in regard to drying times. 5. Paint the Engine: After the primer is fully dry, apply high-temperature engine paint. You can use a brush or a spray can, but spr...

Q how many engine hours is too much

The question of “how many engine hours is too much” isn’t straightforward, as it hinges on several variables including engine type, maintenance history, and usage patterns. Typically, for gas engines, exceeding 2,000 hours can be a caution zone, whereas diesel engines, which are built for durability, may run well beyond 3,000 hours without major issues, assuming diligent maintenance. Proper care—regular oil changes, timely replacements of filters, and addressing minor problems before they escalate—is key to extending engine life. Also, a well-documented maintenance history increases confidence in older, high-hour engines. Usage type matters too; engines running at consistent RPMs, like those in marine or generator applications, often fare better over time compared to those subjected to variable loads, such as in cars and trucks. Ultimately, while high hours signal caution, they’re not an automatic deal-breaker. Evaluating each engine on its maintenance, usage, a...

Q can a transmission lock up an engine
JenniferJames

Yes, a transmission can lock up an engine. This scenario typically occurs when the transmission experiences a catastrophic failure, resulting in the transmission components seizing or locking together. Given the transmission’s direct mechanical connection to the engine through the clutch (in manual transmissions) or the torque converter (in automatic transmissions), a lockup can subsequently stall or severely impede the engine’s ability to turn. In worst-case scenarios, this could result in complete engine shutdown or significant damage. Common causes for such failures include severe overheating, lack of lubrication, or internal component breakage within the transmission. Preventative maintenance, such as regular fluid checks and changes, can mitigate the risk of transmission lock-up and protect the engine’s integrity.
