olddirtyrake Posted November 5, 2009 Share Posted November 5, 2009 I have a snapped exhaust header bolt on the passenger side all the way in the back. I'm wondering If a machine shop can drill and tap the header while on the vehicle. I Just finished the head gasket on this thing about a week ago and I really, really don't want to take it off again. If they cant what are the downsides of leaving it snapped, can it harm anything? If they cant is there anything else that can be done, as I said I really don't have the time to go through all that again(Its getting colder every day and my garage is unheated). Funny thing is that I had it drilled and tapped on the exact same bolt while I had it off.(Probably snapped due to expansion and contraction from heat). Though this time I think it was a cheap bolt or over tightening(Kicking myself for not just doing it right the first time). Link to comment Share on other sites More sharing options...
Simon Posted November 5, 2009 Share Posted November 5, 2009 With a snapped exhaust bolt/stud, your exhaust will most likely leak. Mine went from the cold weather tick, which went away as the truck warmed up, to a full on tick, at all times. I can see where the gasket has given way, and there's carbon all over the head where the exhaust is leaking out. Header install is planned for this weekend, if all goes well. One tip I was given to remove those bolts is to weld a nut to the top of it, then try to break it loose with a wrench, or ratchet. That, of course, is if you have access to a welder.

nismothunder Posted November 5, 2009 Share Posted November 5, 2009 Truthly there wont be any harm done to the engine,just the ticking,witch you can muffle if you put sound mate under the hood.I'd be more afraid of the frame rotting off before the stud give you any problems...

edicer2 Posted November 5, 2009 Share Posted November 5, 2009 Only thingi noticed from the tick was it made everything around the leak black and also i noticed a slight power loss and worse mpg. other than that it wont matter at all Link to comment Share on other sites More sharing options...

I've heard that if you take two nuts, and tighten them against each other on the end of the bolt (loosen one that is further on, tighten one that is closer to end) then that gives you plenty of turnable power to break it free, then you can just loosen them from eachother...

As I am sinking a bunch of time and money into this np do you think I should seriously grind frame down to steel and spray it with a protector? I really would be sad if frame snapped. I'm not doing any offroading with this thing yet but plan to in the distant future. Link to comment Share on other sites More sharing options...
