Title: Blown headgasket? Post by swedishbiker on 07/17/13 at 02:58:10 I have drive few km with my bike now. It ticks on the left side somewhere to the head. Now it comes oil between the head and cylinder. The engine was clean washed from the dealer :) My thought is that the gasket is blown and the noise is from that. A blown gasket can sound terribly :) I can feel some wind from that area. Is it possible to remove the head without removing the engine from the frame? I can get Athena S.p.A gasket set, is that good enough? |

Title: Re: Blown headgasket? Post by rodeoclown on 07/17/13 at 03:15:42 I would try torquing down the head bolts first,they may have became loose. |

Title: Re: Blown headgasket? Post by swedishbiker on 07/17/13 at 06:36:36 Aha, thats the leak over the exhaust. Guess that the oil spills to the left side when bike stands on the side-stand. But that should not make ticking noise. Could it be the chain anyway? Sometimes the noise disappears but I can't tell yet under what circumstances. And I believe I can feel some drag from the side, no fan in a air-cooler. The piston bolt? Rocker-shaft? Or what? My ear locate the ticking to left side, at hight were head goes on. |

Title: Re: Blown headgasket? Post by Dave on 07/17/13 at 08:01:24 I would suggest you give the engine a good scrubbing.....then try to find the source of the leak. If you have a blown head gasket.....I believe you may be the first one on this forum. Engines with 8.5:1 compression aren't too hard on head gaskets. The source of the ticking could be the valve train or some piston noise, not sure about the air movement you feel. |

could it be the convection from the fins or maybe oscillation from fin vibration? I get that sometimes too, where I am at a stop and I feel puffs of air against my left leg as I stand on the ground. Also, when was the last valve adjustment? It sounds like you just got it from the dealer recently. |

Title: Re: Blown headgasket? Post by swedishbiker on 07/17/13 at 09:21:06 I did the valves with an indicator clock. Difficult as valves has the same rocker but it can be done :) I got them 0.1 +/- 0.01 mm |

Title: Re: Blown headgasket? Post by justin_o_guy2 on 07/17/13 at 09:24:08 There is a minimum lash,, you dont want them too tight. It should be ticking like a sewing machine up there.. I cant remember the specs but I think one of them is around .004", I dont know what your .1 mm is. |

Title: Re: Blown headgasket? Post by swedishbiker on 07/17/13 at 09:51:37 Manuals say, 0.08 - 0.13 mm. I took my camera and went out to record the noise. And there was no noise :( It did tick this morning when I ride to the mailbox. I don't believe in the blown gasket any more. I have a feeling that the engine has never been opened, looks like factory built except for the cam cover. Do you open the head bolt a little first and then torque or torque without that? |

The proper way to torque the head is labor intensive, and usuallly occurs when the head plug leak is fixed. Two of the head studs are not accessible with the head cover attached, and it takes a lot of work to get the head cover off, cleaned up, resealed and bolted back on. The cylinder nuts get stuck with the heat cycles and washing and drying and corroding and they can only be torqued properly if you take them off, clean them and apply new anti-sieze....then put them back on and torque them. |

Title: Re: Blown headgasket? Post by justin_o_guy2 on 07/17/13 at 12:06:04 I have 20,000 miles on mine. Head has never been retorqued, no leak. |

So for me it makes sens to loosen them up first. Have read posts of broken bolts :) here. |

Title: Re: Blown headgasket? Post by justin_o_guy2 on 07/17/13 at 12:34:10 Id fix the oil leak & leave it alone, |

Have read posts of broken bolts :) here.[/quote] The problem with our head bolts....is they are studs with nuts and 3 of them are out in the environment and they corrode. They get incredibly stuck together and getting any kind of accurate torque reading from them is not likely if they are not cleaned and lubed. (It might be better to just leave them alone). When I took the nuts off my bike I could feel the studs twisting when I pulled on the wrench....then they snapped loose as the corrosion let go. The previous owner had always stored the bike indoors and it only had 1,200 miles on it when I took the head off.....I can't imagine how stuck they would be on an older and more used bike. |

Title: Re: Blown headgasket? Post by swedishbiker on 07/17/13 at 13:29:07 The nut should come of easy, if not heat it. The studs may may be harder. But I have not work with this engine yet. Have done few VW air cooled engines, similary :) |

The broken bolts on these engines are usually the exhaust header bolts, which should be snug....but not really tight. And these bolts should also receive anti-sieze when they are installed. The other prolblem area is the head cover bolts that people tend to overtighten and strip the threads out of the head or cylinder. These bolts are only 6mm and require a low torque. |

I was hoping that someone with better hearing than mine would chime in, but since no one did. . . I don't hear anything in that clip that I'd be concerned about - sounds normal to me. Cam chain is on the other side BTW. If you are close to 10,00 miles - 16,000KM - You might want to take a look at the adjuster though. |

Title: Re: Blown headgasket? Post by justin_o_guy2 on 07/19/13 at 08:47:31 now would be a great time to see how its doing,, |

Title: Re: Blown headgasket? Post by swedishbiker on 07/19/13 at 10:40:12 Well, the noise is louder then what it is on the movie. I got the gasket today so I will remove the cover tomorrow and have a look. |
|
Title: solved Post by swedishbiker on 07/20/13 at 05:41:47 Done :) and it sounds as a new one. Thanks to verslagen1 for it. To do, sew a cover for driver seat, put on a new drive belt. And fix the oil leak :( from cam cover. |

If that's idle on a warmed-up engine, then it sounds a little fast to me.... |
