Re: Header Bolt Battle
Yes, its D/S and right in the center, decent access from the side of the car.

Re: Header Bolt Battle
This is probably too late in your case but one trick I learned from My Military days is try to tighten first before trying to loosen. The theory here is that the best flats on the bolt are on the tighten side and all you need to do is break the bolt loose which is what you are trying to do prior to loosing it. I have also seen a brass drift used to tap on the top of the bolt head to break the siezure. Not hard but a firm tap.
Good luck! |

If it's the screw next to the center stud, worst case just don't cut it flush for now and don't put a screw there. I only do criss/cross pattern on my headers 2 screws on each header tube one the center stud tubes i don't even put screws the stud does just fine on the inner side and just put one screw on the outside of the center tubes. I can explain a little beter on the phone Pete

O____X_O____X___X____O_X_____O X____O_X____X_S_X____X_O_____X I have also used this way with no issues. This is the way i was trying to explain to Lee. The reason i do it like my previous post is visaul all top screws are in and people stop telling me i'm missing screws, my reply "my wife thinks the same" LOL Pete

Re: Header Bolt Battle
So....this is a bolt installed in a header, not the original exhaust manifold.
Then this bolt must be only about 3/8 inch showing after you grind off the head (maybe a bit more with the gasket). Pete's idea of just grind it off sounds like something I would do After I applied a little heat and vice grips but not too much heat I did not fill every header fastener position with a bolt either Last edited by Dynomite; 03-01-2010 at 07:12 PM. |
