looks like my riser gaskets are leaking |

JP, you heat the exterior first in hopes that that metal will expand first before the heat soaks into the bolt and allow you to break it free.
Pete, I ship ups too haha. Hey, check your PM, got a buddy with an Atom skier question. |

JP - A propane torch isn't hot enough. I agree heat is the best way to get the shanks out. You might want to pull the manifold off & take it to a muffler shop that has a oxy/fuel torch. They do this all the time.
The way it was taught to me is that the heat expands the threads so much it breaks the rust bond. |

Great idea Chris then he can pull the heads to get the broken manifold to head bolts too . I look at my 95's bolts and would like to change them but I don't need a big project this year

I've drilled my fair share of 351 hex bolt heads off from them being rusted so much they are round instead of hex ha.

I pulled the manifolds off my '87 (Motors an '88) this fall, as far as I know they were original with about 600 hours, the manifolds rusted through and hydrolocked the motor. Three days in a row of applying home made 50/50 acetone/trans fluid and the manifold bolts spun out easy with a allen socket and a standard socket wrench. No heat, no impact. Same for the riser bolts. All of the bolts could have been re-used. You just never know until you try. I seem to have lucked out on everything else too. We put several hours on with the new manifolds and no apparent ill effects from the hydrolock.

Yes you never know. Removed the port manifold from my 74 351 to repair a crack and the bolts came out with no trouble. No idea if they had ever been removed in the past 40 years, but if they had been there was no evidence of it.

I guess I could try to remove the manifold bolts, but if one of those breaks, I'm pretty screwed. I don't have any other heat source aside from the propane torch. I guess I could always get some MAP gas. Would that be hot enough?
Boat has over 1750 hours on her, snapping bolts is something I expect although the header bolts don't seem too bad, but definitely rusted. |

JP,
The MAP is hotter but with a small torch you won't get enough of the needed heat. If you do try the MAP, make sure the torch is rated for it. |

So another $60 just to "maybe" remove the bolts? I think it may be easier to remove the manifold and take it to a shop for removal. |

Chris, I bought one of them for my daughter for glass art. She never used it so I ended up with it. I used it one day for bending some 3/16" x 1 & 1/2" stainless and trust me, it is hotter but just like a single gas torch, it won't provide enough heat. Plus, I went through 3 tanks of oxygen to bend 4 pieces of the stainless 45 degrees. Oxygen goes real quick with any oxy acetylene rig. |

I would make step 3a: acetone/atf soaking for a few days and then a bit of MAP gas heat with the channel lock or vise grip.
If that doesn't work and a real torch is necessary tow the boat there instead of trying to remove the manifolds from the heads. |

Are we still stuck on the riser bolts? Seriously a lot of over thinking here, 50% of the time those bolts will snap but soak them, heat(map would be better but I've used propane), a rap on top with a steel hammer and vise grips they have always come out for me. Your gonna kick yourself when they just turn right out. The suspense is killing me.

Gonna soak them once a day until Friday, Then I'll try my bolt extractor/vice grips and some elbow grease. If they don't pop out, then I guess I'll have to try something else. I tried a manual impact driver before I broke them and that beating didn't loosen a damn thing. Lol. |

I have the best wife.
She's been hearing me bitch about this issue for the past week or so. Each day I've been coming home from work, uncovering the boat, and applying PB Blaster to the broken bolts sticking out of the manifold. We spoke on the phone yesterday as I was leaving the gym. She asked what I was going to do when I got home. I explained, the same thing I've been doing the past week, lubing up those bolts hoping they come out easily Friday. She giggles and say OK, see you in a few. I pull in the driveway to see the cover is already off and the doghouse is up. I was like WTH?? Up pops my wife and she's wearing gloves and has a hammer in one hand and the PB Blaster in the other. She had removed the cover that morning and had been wiring brushing around the broken bolts and soaking them in oil, and beating them with a hammer 3 times that day. She said she felt like helping out. She even went so far as to Google ways to remove broken bolts. Needless to say the help was greatly appreciated. I must say I have an amazing wife. Tomorrow is the day I make another attempt to remove those bolts. Fingers crossed and I'll keep you guys posted on how it goes. |

Lol. I explained that to wifey and she laughed at me and said tough S#!T. She wasn't all done up, so no pics. Certainly wasn't going to piss off my helper. |

I certanly agree. JP, I see you're still stuck on that over rated Madison av. advertised PB blaster! Your first post you said you were going to use the 50/50 mix. |

Yeah, I've heard good things about it and figured I'd give it a whirl. I'm sure the 50/50 mix is better, but at this point it is what it is. It seemed to work well at loosening up the other 5 bolts. IF for some reason I wind up having to remove the entire manifold, I'll be sure to try the 50/50 mix out on the manifold bolts. |

Geez Pete, PB is not bad stuff, IIRC it is typically rated at the top of most of the over the counter type penetrant.
I would say though at this point personally would probably be trying some fitty/fitty on that bitty. Good Luck JP, and when it works give wifey all the credit!! |

Success!....... but not without some collateral damage.
I used my new drill and craftsman bolt extractor and they came right out. Had to cut the hoses from the risers to the muffler. We tried heat and lube with no luck. Local dealer has new ones for $42. Risers and manifold flanges look great. Still have to chase threads and get replacement bolts. Also looks like there are several leaks in my muffler. The sides have movement all the way around the edge of the flat face, and theres another crack on the down tube. Oh yeah, when I turn the muffler I hear something flopping around. Is this a baffle of some sort? Heading up to dealer for new hoses and gaskets tomorrow. May rip the carpet out as well depending on how much I get done. Here are some pics: |

Man, this rig sounds like a headache. Time to wash your hands and upgrade. I'll take it off your hands.
And time for a Y pipe. |
