    Bad valve guides?

    I replaced the valve stem seals ony 1991 Chevrolet K1500; 4.3 V6. The mechanic stated that the valve guides are bad. I am no mechanic and don't know all of the ins and outs of engine mechanics. The engine seems to be smoking as bad as before or worse. What should I expect if I replaced the...

    Blending #1 & #2 diesel

    A friend has a son that runs semis. He said that his son was told by the fuel supplier that #1 & #2 diesel fuel separates and doesn't blend. So his son just runs #2 with additives. Anyone else heard this in regards to recent diesel fuel products?

    Replaced the valve stem seals.

    1991 Chevrolet K1500, 4.3 V6, approximately 130k miles. I've owned this truck for about 6 years. The seals have been bad since I got the truck. Finally decided to have them replaced. Compression was good in all cylinders (140-170). Valve guides are a little worn. Other than no more blue smoke...

    Oil capacity???

    How do automobile manufacturers determine how many quarts of oil are necessary for a given engine? I have a 1991 Chevrolet K1500 with 4.3 V6. Capacity is 5 quarts. My daughter has a 2002 Blazer with 4.3 V6. Capacity is 4.5 quarts.

    Switch back to OEM tire size?

    My 1991 Chevrolet K1500 pickup originally had 225/75/16 tires. The previous owner, my employer, put 245/75/16 tires on the vehicle. I will probably replace them this summer or fall. I'm guessing that the 225 tires will be cheaper than the 245. Other than price, is there any reason not to switch...

    2016 Dodge Grand Caravan TPMS question

    I have a 2016 Dodge Grand Caravan. Finally, after 3 years, I have purchased a second set of rims for my snow tires, along with TPMS sensors. The sensors on my vehicle don't tell you the tire pressure nor which tire is low. A low tire light comes on and you have to check the tire pressure in all...

    Tire and alignment question

    If I am going to get tires and an alignment, probably at different locations and within a week or two apart, does it matter in which order I do that? Does having new tires on the vehicle before hand make the alignment easier or more accurate?

    Domestic passenger car production?

    If a product isn't selling or is otherwise unprofitable, why build it/sell it? It looks like domestic passenger car production is pretty much going to be a thing of the past. I live in a pretty rural town in south central South Dakota. Population less than 2500. The next town of any size...

    Warming the oil for oil change

    I know many, self included, will take a short drive or idle the engine prior to an oil change so that the oil will drain more quickly. I have a magnetic heater that goes on the oil pan to warm the oil during the winter. Wondering if I can use this to warm the oil prior to changing it? Only...

    Thoughts on CAFE standards

    Ford is virtually stopping production of passenger cars. Dodge and Chevrolet are trimming down their passenger car offerings. Passenger cars add greatly to a manufacturer's overall corporate fuel economy. As CAFE standards tighten, how will manufacturers meet CAFE standards without passenger...

    The heater is "clicking" on my 1994 GMC Sierra. Sounds like a blend door motor. Mechanic friend stated that some of the newer ones have a reset procedure when you disconnect the battery. I just put a new battery in this vehicle. Is there a blend door motor reset procedure for this vehicle? Where...
