I have had the front tubes out 6 times now trying to get it to stop leaking and no luck so far, still leaks (leaks out around front exhaust tube). The rear billet bases are ok!, no leaks. I followed step by step what said Pkforbes87 for the seals install and that is what I do every time and it still leaks. It built up so much pressure that it shot oil all the way up to the head. I was wondering could to be a problem with the oil pump that it is building up too much pressure?...or perhaps the bronze Oil Pump Drive Gear?..... I wonder if with the originals bases it would solve the leak issue. I'm tired of pulling this motor apart Help, I can not anymore and I'm running out of ideas. Anyone have a good idea of what the problem could be?. Thanks very much in advance |

Man I feel for you. I know how frustrating this can be. Maybe you should post where you are located and a second pair of experienced eyes and hands will offer to help you. |

You might be on to something there with that pressure. Oil is pumped up to the heads to lube and cool everything off and then is allowed to dribble down the tubes. I don't think it should be under pressure at that point. Check your breather! Perhaps the umbrella valves are in wrong and it's building up pressure in the crank case. Make sure the breather is putting out air and not sucking it in. |

The umbrella valves go on the intake side where the breather bolt is. Just it leaks when I going on up 2500 rpm, but not at idle, Thanks for the input. |

More RPM = more blow-by into the crank case. If you have a hose partially blocked or kinked, the pressure would build up. If you remove the timing plug, it will spatter oil all over from there but will it still leak from the push rod tube? |

This maybe the main problem. I'll take a look to breather hoses. Thanks for the tip. I am very grateful |

I have checked my breather system and it's ok. The breather system does have air coming out so I know it isn't plugged. I'm running out of ideas, this is driving me crazy. I have missed many trips with friends. Perhaps with Pushrod Cover Conversion Kit from Zippers it doesn't leaks or with originals retainers?...I don't know. I am still unclear as to what is going on here. Someone has had this problem? What´s going on?. (Message edited by buellisticx1 on July 04, 2009) |

No matter. You Just looked for some ideas on what it might be. Thanks for your help Natexlh1000. Regards. |

That squirt of oil is timed with the lifter traveling up in its bore. Using the NRHS billet part. Sometimes you get lucky and the rest..... Doing the install with the heads on. Use the super glue trick. One needs to be careful even then. The trick is to keep even pressure on the base as you lower it. Keep the pressure on it while you get the bolts started and finger tight. If you let up on the pressure the gasket will pop out. The gasket will catch on the lifter bore if you move it around to line it up. It will roll and drop into the bore or get cut. When you set the base up on the tubes. Set it at no higher than the lowest fin on the jugs. That way you will only need to just tap it back towards the jug to align the bolt holes. My bases sit just under the lowest cooling fin. Just enuff to not allow them to drop straight down on install. |

I slide the bases over the top of the covers till set it at no higher than the lowest fin on the jugs. (But never I did keep even pressure on the base as I lower it, I MISSED THAT TRICK! and it's possible that the gasket did pop out and drop off into the lifter bore while I moved it to align the bolt holes over and over again. Next weekend I will get back to try again for the seventh time. Thanks a million for the info. It certainly makes sense. I really appreciate it. I will take into account...... |

Today I have unbolt the front push rod base for lift it and take a glance to the seals and both front seals are completely glued into the base and flat (not pop out) so I don't think is an issue of seals or on install). I wondering if could to be an issue of the angle tube, because I just realized that after done the rocker box, the push rod tube is slightly inclined to the rear side, it doesn't completely straight into the base, it's and for this reason leaks. Could this be the main issue?......First bolt down the base and then the rocker box, is it the way to go? I had the rockers on and off several times and ever since I reassembled it I have had oil coming out around the front pushrod tube base(which didn't leak before reassembled and I'm using the same NRHS billet bases from three years ago and never leaks,weird right?) I think going to try it one more time with new stockers seals ((black in color), new originals retainers and a new push rod tube before buying collapsable tubes. any suggestions?........... |

Could this be the main issue? Don't worry about that - I noticed the exact same thing on mine when installing billet bases, and mine don't have any hint of a leak. First bolt down the base and then the rocker box, is it the way to go? The only reason to remove a rocker box is to get pressure off of the pushrod, not the pushrod tubes. If you're having that hard of a time getting the bases to seal though, you might try removing the heads first.. then you could have a lot of room to get the bases seated perfectly before reinstalling the head on top of the pushrod tubes. Not really the ideal way to do the job, but if I was doing it for the 7th time I'd be looking for alternative methods. |

If I were through this type of hell, I would be installing collapsing tubes like on my old ironhead. Those things used CORK washers and didn't leak! |

Thanks for the response. I'll provide findings. |

No leaks!!! Yes! Ok. Changing from blue Jeams seals to stock seals fixed it. It would appear that NRHS bases combined with stock (black) seals is key here no doubt. Stock seals seem a harder rubber compound and they endure better the heat than blue Jeams seals. I went on a test ride 35 miles and when I get home NO LEAKS!!!. I am thrilled that I fixed my leaking. Thanks to whoever had responded on here for any info that they tried to help me with I appreciate it. Regards. |
