My 2001 ford f150 Supercrew with the 5.4 triton v8 has a loss of power and the engine is running rough I believe both catalytic converters are plugged.
Answer: Any check engine lights? If the check engine light is on and has a code p0420 it is possible that the cats. are plugged. One sure way to check is to check the temperature using a laser temperature gun at the beginning of each converter and at the end. It should be reading as much as the same. If the lower end of the cat is reading lower temperature possible clogging has occurred.
Other ways to check for plugged catalytic converters is to connect a vacuum gauge to a vacuum line and rev the engine at about 2500 rpm. A normal reading is anywhere between 16-21 psi of vacuum. Also you can take out the oxygen sensor on each bank before the converter, one at a time, and install a backpressure gauge. With the engine running and revved up to 2k RPM there should be no more than 2 PSI of backpressure.
There are other things that can cause the condition you have. The mass airflow sensor (MAF) could be faulty, low fuel pressure, multiple engine misfires, etc. The multiple misfire can also cause the converters to be plugged up if running this way for a long period of time because a misfire means that unburned fuel is entering the exhaust and igniting inside the converter, which will melt it. This will usually also have a flashing check engine light.
Ford F-150 Oil Milky
Had the pushrods and hydraulic lifters replaced within the last 5 miles, was told to do an oil change. Drained oil today and it was milky and mixed with coolant. Checked coolant reservoir and drained radiator, no mixing inside the radiator. Not sure what the problem is or where to start looking. Any ideas would help. Heads are not warped or cracked. Truck has 81,245 miles, and ran great before this. Never overheats.
ANSWER: If coolant is in the oil, but no oil in the coolant then you have a head gasket problem or a cracked head. Pressure from compression pushes coolant into the oil. The engine does not need to overheat to have a head gasket or cracked cylinder head problem.

1991 Honda accord wagon. Right front strut or spring is squeaking when turning the wheel. Also I pushed on the hood and the right side moves up and down really easy but the left side doesn’t. Does it sound like strut
