386000 R.I.P. TIME FOR REBUILD
Bought new in august 1997 for $25000, thought it was a lot of money but for a gasoline truck to go this far I am happy with it.
Was hoping to get it to 400,000 but started getting a clicking/knocking noise like maybe a rod bearing, also, loss of power and oil leaks so, I decided to pull it and rebuild. i just removed the intake manifold and saw how clean the heads look which means to me that I kept the antifreeze up to date. Anyway, I will pull it monday, disassemble it and take the block to machine shop for inspection.
Hopefully, I can do a .010 over, no more. Removing all of the secondary components out of the way is a pain and saw where some bolts/nuts were difficult to remove. Wish there was more space to remove the flex plate nuts. That drivers side erg tube to manifold is hard to break loose as well.
Has anyone else gone this far on their f150 4.6?

Yea, mr dirt, but I would get lost in that, I want to "one up" everyone. How many others have gone 386000 miles???? Not many I would bet.
Here's an eye opener:
Tore the motor apart, looks perfect, no wear....NO WEAR, if you can believe that.
Just got word today that the heads are perfect and they are waiting on new seals. Getting the crank polished, cylinder walls have no ridge ring at all and still has a good crosshatch. All bearings perfect with no scratches/uneven wear patterns. Shocked to say the least. No wonder they stopped making this engine.

I'm not an expert but I did not see anything that would cause the clicking noise. Machine shop said the heads were perfect, no problems found. Bearings looked great. To me, clicking means, metal on metal somewhere, but I could not find it. Did notice lots of carbon buildup on the "OIL RINGS" and the oil rings were completely stuck in the compressed position, which is probably why I was using oil and maybe loosing some power.

That is truly AMAZING!!! I am glad I bought a 4.6 now. Since mine has just tripped 100K and I change the oil every 3-4K she will probably out live me. .
My long lasting Ford story was my 63 Galaxie 390. In 2009 I took the oil pan off to replace the oil pump. At that time I pulled the main bearing caps to replace the Main bearings. Much to my surprise the original FoMoCo bearings dated Aug 11 1962 were still silvery babet colored and were still well within specs so I just put them right back in. I am fairly sure she had tripped at least once at that time. The old girl is still running strong to this day

My 2000 4.6 just blew a plug a few weeks ago. Looks like they fixed the problem in 2001.
Check out my thread about about what I found on the problem:

Excellent info in your other thread. I had a relatives Corolla blow a plug out and I feared the worst. The threads were fine, it just backed out over time till it blew out. Screwed in back in, the car is till running today with 280k on it. I plan on re torquing
all my plugs this weekend. Thanks!
