Had oil, air filter, spark plugs, wires and fuel filter changed. After first time drove over 10 miles. Was driving around 60 miles an hour when suddenly white smoke came from under hood leaking fluid from under engine around bolts. That wasn't there before. Once engine cooled the smoking stopped oil level reads normal still dripping slightly. Can you please tell me possible reasons?

Even with the leak the oil pressure is perfect. Pulled over as soon as it happened sat there for about 15 minutes then drove home no noise from the engine no more smoke and didn't over heat the rest of 30 minutes back to my home.

Hi,

Looking at the picture, I can't tell where the leak is. Everything looks wet. Since the oil was just changed, confirm the drain plug on the oil pan is tight. Also, check around the oil filter for evidence of a leak. They may have double gasketed the filter which will cause a leak

On the 4wd models, there is a remote location for the oil filter. If you look under the center bottom of the truck, you will see a plastic access panel. Open that and see if that is where the leak is coming from.

See pic 1 below for the location. Note that the remote location requires high-pressure lines to run to the adapter for the filter. Inspect them as well.

Let me know what you find or if you have other questions.

Take care,

Joe
