Should the lifters just be soaked in oil first or should I run the oil pump to get oil pressure in everything, and keep it "pressurized" while adjusting rocker arms??

Just did mine a few weeks ago and asked the very same questons. Got different answers.
I went with the not soaking them in oil while installing them and adjusting them. Just dip them in oil prior to putting them in, but not long enough for them to get saturated internally. Adjusted them 1/4 turn, before locking them down. Since they were all new and not "charged" with oil, all of them felt the same and made the adjustment very easy.
Do the adjustment on the rockers. And then when you are done, pour oil into the valley over the lifters. You'll have to change the oil anyways snce you had the manifold off.
Then you need to spin the motor using the starter with all the plug wires off and plugs out, and you'll see oil up in and dripping off the rockers in a very very short period of time. I actually handcranked it at first using a wrench on the crankshaft pulley, and was beginning to see oil up top. At the advice of a friend, I just let the starter do all the work for me. Not long bursts either. Just a short burst, and then get out and look for oil.
The big worry you'll have, is if you change the oil pump. That's when getting in there and actually priming the system it is a necessity. But just changing the lifters, it is already primed.

You only need to coat them with oil. Soaking them does jack s***, the plunger is pressurized by an internal spring, oil pressure is what keeps them pumped up and you can't pressurize them prior to priming the oil pump. Slather 'em up and install them. And it doesn't matter which way the hole points.

Good point. Took me a while to figure that one out, too.  |

I primed the system before I did i just to see if it made any difference, didn't notice any.
I had that split second of anxienty the first time I put lifters back in too, because I then realized I didn't notice what direction the hole was when I took them out.

I primed the system before I did i just to see if it made any difference, didn't notice any. Just as an FYI in case you're ever there sometime; When I was researching rocker adjustment methods, some of the references I found online made mention of backing them off and letting them stay backed off for a minute or two to let the plunger extend all the way up. But that would only apply to adjusting rockers with old lifters already in place. Wouldn't apply to new lifters. When I adjusted my old ones before actually changing them, I did notice a difference from rocker to rocker. Like some had more pressure or spring to them than some of the others. On some, it took a slightly larger degree of force to crank them in. Some had literally no resistance at all. They were relatively new as it was, since the motor only had about 6k on it, so I just attributed it to the bleeding off, or lack there-of, from lifter to lifter. |

What kind of lifters did you have then? I've noticed that same thing before too with stock and ford motorsport lifters. Jay was pretty adamant about using comp lifters and they were all the same when I adjusted them. |

If you adjusted the Comp lifters new out of the box, then they would have probably been the same while doing the adjustment. I found the same thing with my new (last set of) Ford Racing lifters. The ones that I mentioned felt differently were the original Ford Racing lifters. Kieth Craft installed them when they built the motor. And I went ahead and put a new set of Ford Racing lifters back in their place. The general consensus here amongst the racing community was that Ford Racing lifters were plenty good enough of a lifter to do the job. |

It's running, valvetrain is noisy but Jay said with those ramps and lift numbers the noise sort of comes with the territory. Now if my fan controller would get here I can take it out to do some datalogging to make some minor corrections to the tune I'll be set.

My Scorpions are noisy as hell. Sounds like a Sears and Roebuck sewing machine.  |

I hotwired the fan this morning so I could run it. It's either a little quieter or I'm getting used to it. I've got crane stud mounts, and yep an old sewing machine is a fitting comparison. |

Engine now has a vicious knocking sound coming from DS rear of engine, mostly noticeable during acceleration, cruise and idle not so bad, and not noticeable during deceleration. Have I said f*** lately!?!?

Rockers sound more like a typewriter noise... not so much a 'knocking' noise.
Did you figure out anything?

I agree. Knocking usually means bottom end. That sucks.  |

Yeah, it was three rod bearings and a main that were bad, looks as if something was wrong with the crankshaft. Look here> http://www.badassmustangs.com/forums/index.php/topic,20157.0.html |
