    never used the stuff. the reason your leaking is the jugs/cases are not mating properly. one or the other is warped. a big reason that warpage occurs is improper warm up. the metals are expanding at different rates. the engine should be ridden about 8/10 miles to warm up properly.....trying to keep it under 2500 rpm.......60mph or so........
    when ya remove the cylinders, use a straight edge to determen which is warped, and have a machine shop repair it. you may try some type of silicone sealer...................hope this helps a bit.......:)

    one other thing.....i would not use any type of "oil sealer" in an engine.....it will stop oil flow at leaks, and other small galleys.....such as lifters, rockers.....ect...............:)

    or if the machine surfaces are good you may have

    1) cut o-ring gasket (twin cam) or cut gasket on evo
    2) O ring on oil passage not in place
    3) loose head bolts

    I would remove the top end and check all of those areas

    No other way..

    The Hayden is fix is NOT a goop at all. It is a machined brass fitting the aligns the oil return hole on the jug to case. The EVO is notorious for piss poor alignment of the jug and the dowels leave too much twist. I used a ton of these myself and never had a leak, weep or seep at a base gasket joint again. Every top end refresh, base gasket leaks etc got a thorough laping with the Trock lapping tool and the case mating surface checked. I used Honda-bond on problem bikes along with the oil fix. It is used as gaskets on Acuras and does not creep and properly used will flat seal a base gasket.

    Honda-Bond is of the Hylomar family of gasket compound / sealers. It is different than Yamaha-Bond which we used heavily in MX years ago. I was turned on to it by an Acura mechanic / custom builder. It is used on Acura's as a gasket in quite a few places.

    I used to go to the local Honda dealer (auto) and ask for it. Also, I highly recommend lapping the base of the cylinders to get them squared up. I use plain old paper gaskets since the metal / RTV gaskets would defeat the purpose of the Honda-Bond.

    I had written a long article about the procedure but I cannot locate it now... Make sure that you do the torque procedure just as it is in the service manual as it is how you get an even tension on the cylinders / heads. The torque method is different than usual in that it uses the Newton method. Use a light oil such as 3-1 on the threads. Do not use anti-seize or heavy oil as the torque values will not be accurate. WD-40 will not provide sufficient lube either. After torquing let it set for 24 hours for the Hylomar to set up properly. You can finish the assembly but don't light her off until it sets up for 24 hours. I always heat cycled the engine several times before riding it. This allows the engine to settle in and time to spot any small issues.
