Replacing a 5.2

Replacing a 5.2
I have a 99 Ram 1500 4x4, ext cab, 5.2. It has 213,000 miles n its starting to leak oil. Oil is all over the starter when I look underneath, and all over the oil pan. It seems like theres oil higher then the oil pan gasket, im not sure if it would spray out of a bad oil pan gasket or if its leaking higher do to a rear engine seal. The valve cover gaskets aren't leaking. With such high mileage, im contemplating whether I should just buy a lowet mileage motor n swap them out.. Any input regarding what I wrote to this point would be appreciated. But my two questions are this. One, how much would it cost to swap out a motor like this, reasonably, or how many hours labor should I expect to be charged. And second, if I was to replace the motor, is it possible to insert a 5.9 in place or the 5.2?

With you doing the work yourself, you'd have to find an engine via craigslist. Looking online, there are 5.9 engines with 125,000 miles for $425 (in my area). You can for sure put a 5.9 in place a a 5.2, it's the same engine block and everything, just a bigger bore and bigger stroke, externally, they are the same. Before you put the motor in, you'll want to fix the plenum and I'd recommend that you do a double roller timing set and a water pump. You're probably looking at $250-$300 depending on where you shop (that's with an aluminum plate to fix the plenum). You'll also want new distributor cap, rotor, wires and plugs. Time wise, you can get the motor out in a day (it's electrical connections, the exhaust, fan/shroud, drain fluids, 2 motor mount bolts, 6 holding the engine to the tranny, 2 engine to tranny struts, remove the starter, flexplate cover, 4 torque converter bolts, and be sure to remove the crankshaft position sensor. You can probably get it out in a day. Fix the new motor another day (or before you even pull yours, so it's ready), and drop the new motor in a day or a little more.

Around 8 hours labor for shop time, at whatever the labor rate is in your area.
If you go with a 360, you MUST use the 360 flexplate. Also wouldn't hurt to have the PCM flashed for the 360 when you are done. Or, buy a tuner, that knows about the 360. (this is actually the better option, albeit, more expensive. Dealer will give you the death flash.)

Go to rockauto.com for all the parts to do the rear main and pan, pretty inexpensive parts wise and if you have some mechanical ability you can do this job yourself and really save some money!
