"Dremel" is a cheap homeowners die grinder. |

I think the link probably showed a cutoff wheel. Get the reinforced ones, the cheap ones shatter very easily (wear eye protection, of course).
BTW Pete, my Dremel may be a cheap homeowners tool, but it is 30 years old, still running on the original brushes & has been run hard many times. It has been a great tool. |

So just take a cutting wheel and cut an x in the head,and then whack it with a cold chisel?

Chris, You are correct. I should have used the term "inexpensive" rather than "cheap". I too have enjoyed having a Dremel. I used to think of them as a gimmick until I bought one for a project and found out how handy they are. I've never had issues with brushes but rather bearings. The bearings went out on my first one so I just went out and bought a second Dremel kit. |

So, the Dremel works great. I actually had to cut the bolt sideways against the manifold, because I could not cut an x because the bolt was so far gone. Anyhoo, the larger reinforced wheel was able to cut right up to the manifold and then I followed it up with a number of shaped stones, and it popped right off. I soaked it with PB Blaster, let it sit, and when I hooked up the vise grips, they slid right out.
Thanks Guys. Tom |

Good to hear Tom. Damn, I forgot all about telling you that the reinforced wheel would probably work best but I'm glad you figured it out.
I have an air compressor with a cutting tool but that thing just wouldn't get in that tight space at all so no reason to mention it. It's always available if you need one though. Again, let me know if you need any help. I'll do whatever I can. |

Hey Eddie, I actually used this as an excuse to go to Harbor Freight and buy a small die grinder and some diamond grinders, but the Dremel actually worked better! Thanks again for the advice. Tom |

I ran into this issue when replacing the manifolds on my 1970 ski nautique. I used a grinder to take off the head of the bolt and the with the manifold removed used vice grips to unscrew the base. This probably wasn't the correct way to go about it but it worked well for me

I did much the same but drilled 3/16 hole in center of head as pilot then 3/8 till the head popped off then vice grips to remove what was left after removing manifold.

I realize the thread revolved more around stuck bolts (which is a good topic) but, the OP was doing this to change valve cover gaskets.
For others reading, you may want to try a swivel socket to access valve cover bolts. Not a socket with a swivel attached but a socket with the swivel built in. http://www.amazon.com/TEKTON-4963-Impact-Universal-3-Piece/dp/B000NPT6IE/ref=sr_1_1/189-9134765-7127868?ie=UTF8&qid=1402400783&sr=8-1&keywords=swivel+socket The U-Joint type are narrower than the ball/cup type like sears has. I was able to easily access the valve cover bolts to snug them up last year (87 nautique). I believe you could get them off without removing the manifolds...but, I could be wrong. YMMV -Chow |

You are correct. I've done it before too using standard 1/4" drive tools. I slid the socket in from the front, it won't drop down from the top.
