Just picked up a '02 4.6 one week ago today. Has 133k on it. Was an impulse buy, but looks to be very well taken care of inside and out. Have only driven it the 20 miles home to my garage that night. Got it up to about 130 mph on the interstate, drive the heck of it on the back roads to my house, and it seemed very tight and solid. Has not moved since, lol!
I'm replacing all the fluids (engine, transmission, diffs, coolant) and filters (engine oil, engine air, cabin, transmission), and cylinder head gaskets (evidence of oil leaks) and plugs.
So far from tearing it down, the only thing I have noticed is that one coil has been replaced, but all 8 are bone dry (no oil on them). Everything else appears original. Some pixels are dead in the DSP head unit, but I'm replacing that anyway with aftermarket.
No service records, met the seller in a high school parking lot and did a cash transaction. Almost got him down to 4 figures. It seems some of you guys have spent that on maintenance in a single year! Wish me luck! I'll probably need it!
