Hi, some of these engine cylinder heads were manufactured with a machining flaw that will leak coolant on the right side of the cylinder head. A coolant pressure test of the head will need to be done to verify the...

When the engine is cold, the viscosity of the oil is higher along with the internal bearing clearances in the engine. As the engine warms both the viscosity of the oil lowers and the engine bearing clearances can increase dropping...

Hello. It sounds like the transmission isn’t shifting gears properly. A problem with the first, second, and/or third gear can cause difficulty with acceleration. Another possibility is that the catalytic converters are clogged (https://www.yourmechanic.com/services/catalytic-converter-replacement) causing poor acceleration. When this happens...
