99 E-150 hard start

[kevbo240zz]

I was helping my friend work on his 99 E-150 4.2L v6 with 105,000 miles. he turned the key one day and it only clicked, so he put a new battery in it, then the same thing it only clicked. I came out and put a starter in, it turned over slowly and stopped. I pulled the plugs, they were original and bad! i decided to change the oil too, when i pulled the drain plug, about a quart of water came out first, then the oil. I refilled it with new oil and filter, cranked it a few times with the sparkplugs out and it turned over fine. then i put in the new plugs and wires, it turned over attemped to start, and when i tried again it turn over slowly once and stopped. I would assume the coolant maybe be original as well. any ideas?

You can do a search here, many threads over the years, but I can pretty much bet you have a leaking lower intake manifold gasket and possibly a leaking timing chain cover gasket.

I strongly suggest you do not try to start the engine again until you get the problem checked and corrected.
Further attempts can result in severe engine damage.
