Hello everyone.
This will be a fairly long post about what happened to my motor due to what I believe to be an oiling problem. If you can offer any advice, please do so. If you can learn anything from my mistake, then it will be worth the trouble to me.
OK, over the summer my father and myself tore the 460 out of my F250 and decided to completely rebuild it. We started by having the local machine shop bore it .030" over and turning the stock crank .010" over on the mains and rods. We used Clevite bearings for both with part numbers MS1039P-10 and CB818P-10(8 ). We also used a Melling high-volume oil pump part number MEL-M84BHVS. We got the oil galley plugs and the freeze plugs in a set together and had the same machine shop install them. We got the Federal Mogul rings part number SLP-E-296K030 and installed them according to the Ford factory manual. That should be all the information pertaining to the issues with my motor. Now, we finished the rest of the motor and got it in the truck. Next came break in time. Well, the first time we tried to break it in at 2,000 RPM, it was very loud and sounded nice, but the headers started to glow red. That wasn't that big a deal at first because we figured that it was probably just the timing needing adjustment and we would do it after the motor was broken in and we could idle it. Wrong! We noticed some smoke arising from the passenger side toward the rear of the header and saw that oil was dripping out the filter on the valve cover breather. The oil started to ignite when it dropped so we shut it off and decided to make a baffle inside the valve cover since the tall Moroso's that we bought didn't come with any. The baffle came out very nicely, but it didn't solve our problem. We then figured that it must be the high volume oil pump and that we should just extend the hole a little with some tube that we threaded into it. It ran like that at 2,000 RPM without any oil coming out the tube for about ten minutes and then shut off. Oh well, just turn it back on and finish the break in. Nope. It won't even turn over now. Not even with a breaker bar on the big bolt in the front of the motor. So now it's time to take it apart again. We pulled the motor and found a great deal of metal chips and chunks throughout the motor. It turns out that the only real damage is two of the rod bearings. Of course it chewed up the crank and warped two rod caps in the process, but it's better than it could have been. Well, we still suspected the high volume oil pump of sucking the bottom end dry and putting it all up high and we were going to just replace it with a stock one and call it a day, but a very knowledgeable and respected "Ford guy" who has built his fair share of 460's including a 700+ HP pulling truck said that it is definitely not the oil pump. He said that we either missed an oil galley plug and it's pumping the oil up top or we put the rings on wrong. He said that the rings should go on across from eachother with ones 90 degrees to those. I'm not sure whether to do it that way or the way the Ford factory manual says. That is all the information that I can think of to tell you so that you can help me figure out what happened to my poor motor. If you need any more information, just let me know and I will tell you. Sorry for such a long post, but I wanted it to be as precise as possible so that the correct solution can be found.
Thank you very much, Austynn.
