After I removed the Fenton headers , stainless exhaust, Duel intake manifold, Rochester, water lines to the manifold and water pumps. The engine ran for only about 30 minutes to break the cam in about 10 years ago. The Engine builder said that heads were magna-fluxed, new valves, guides, springs, new seats the works. It looks like something maybe leaking? C**p I hope not. Trying to put the engine back to stock as close as I can get. Please help with some thoughts.
Did the builder use some sort of sealer on the head gasket? Was the head retorqued after the initial run-in? Chances are that a good cleanup of the "leak" and another warmup and a hot retorque will stop any seepage. Following the recommended tightening sequence in the service manual, loosen each head bolt one at a time about 1/4 turn, and retighten them to the proper torque specification. Loosening and retorquing a single bolt at a time will keep the head from shifting position. Jerry

It was either Indian Head or Permatex. And no the head was never retorqued. Okay, I will give it a good cleanup, run and retorque. Thanks Jerry! Heck, old Harley's leaked and they ran Fine.
Harleys don't leak- - - - -they just "mark their territory"! LOL! Jerry

And I disagree about Detroits. When I got back from the run Amtrakjoe and I made to Kansas City (was that 2013?) in the GMC 9500 with the 6-71 Jimmy, it wasn't leaking a drop. I topped off the engine oil before leaving KC and when we stopped two days later in Racine, VA (White's Truck Stop) it wasn't leaking a drop and it hadn't used one bit of oil. It didn't start leaking again for about a month. Never ran hot, either -- even going through the mountains of Western Maryland -- just drop a gear, hit the slow lane and keep the revs up against the governor (and have your hearing protection in)-- happy happy, joy joy.
I don't know a thing about Harley's, but my Green Screamer was happiest when you had the hammer to the floor all day, all week. Your mileage may vary.

I worked 32 years for a ocean going tug and barge co., at there maintenance facility. we had a guy that rebuilt our engines, 4-71, 6-71 8v-71's they never leaked. these were generator engines and ran for weeks at a time.
There was a specific pre-trip procedure we observed when I was driving a Detroit 8V71 in a 64 Freightliner cabover- - - - -
1. Get in a big argument with the wife before heading to work- - - - - 2. Kick a tire and bruise a couple of toes- - - - - 3. Slip on the cab step and skin up a shinbone- - - - 4. Slam the door on a couple of fingers- - - 5. Pour a cup of scalding hot coffee from a thermos bottle- - - -and spill it in your lap- - - -
The above process assures that you stay whizzed off all day and you drive the thing wide open! The Detroit loves it! Abusing a Detroit engine is like wrestling with a pig in a mudhole- - - -you both get filthy- - - - -and the pig enjoys it!
LOL! Jerry
