Replacing Timing Cover - How long?
Hi all,
My 2001 Dakota with the 4.7L and 198,000 miles started to overheat on warm days last summer. so I figured it was the water pump, and yesterday took off the pump to change it, and found that the timing cover was pitted around and behind the pump impeller.
A few questions:
1) At the top of the picture (in the water pump cavity) there appears to be a small hole forming. Could this lead into the timing chain space?
2) In the center of the picture is a threaded hole. Is that normal, or is there supposed to be something in there?
3) If I were to change out the timing cover, what else should I plan to do - crankshaft sleeve, timing chain, new sprockets?
4) What kind of job am I in for if I do this myself?
Thanks for looking...And also, if anyone has a good parts site to purchase the timing cover from, I'd be interested. RockAuto doesn't seem to have one.
