1998 ford F150: Check Engine light..Engine light came..1 qt low..drove

Customer Question

Yesterday my 1998 ford F150 Check Engine light came on. I pulled into a gas station and check the oil it was 1 qt low but is due for a 3000 mile change and that is about normal. I noticed the positive battery cable had a lot of corosion so figured that must be the problem and drove it 10 miles home. This AM when I went to start it there is a loud tapping noise like a lifter or rocker. It doesn't run rough and idles where it should its just noisy.

Hi thereCustomer The truck being one quart low and the terminal being corroded will not turn the " check engine" light on. The light is being turned on because of an emission concern. You could go to a local Auto Zone or place like that that would retrieve the codes for you and then you would atleast have an idea of what system is at fault. Unfortunetly I cannot hear the noise that you hear, but I can tell you that these trucks had ALOT of exhaust manifold troubles. And when they started to leak they do produce a noise similiar to a tapping like a lifter. But there are so many things that would turn that check engine light on, if the truck is running ok it could just be a sensor at fault. But getting the codes checked has to be the first step. Thanks Steve

Thanks . that is a plausible answer. I had'n thought about a manifold leak. It was not making that noise as I drove it home so I was suprised this morning. Mostly I wanted to feel safe to drive it to the mechanics shop about 3 miles tomorrow. Run by a bunch of ex ford dealer mechanics and Service Manager. I love this truck it has never given me any major problems and at 144,000 miles I want to drive it 100,000 more!
