Well my headers are in but i have 8 bolts that broke into the heads i am going to get put aluminum gaskets on it so i get a better seal for now will that work until i get the funds to take it to a muffler shop and get the holes fixed.

 

also i think the ahole put the wrong port type gaskets on there to begin with would a 94 5.8 have oval or rectangle ports on the heads? and would gaskets for a 5.0 work on a 5.8 Arent the bolt patterns the same.

 

I'm still a newb to the F150 and this site, but if I were you I wouldn't drive the truck unless I had to. I think you would be running the chance of warping your header flanges.

 

the truck doesnt move that much anyway it sits at home unless the wife needs it to run an errand (which doesnt happen very often). Anyone have the answer to the gasket questions. The only header gaskets i am finding are for 302 last time i checked they had the same mounting surface as the 351 i just want to make sure.

 

8 bolts , there going to leak , the 5.0 & 5.8 gaskets should be the same , they share the same heads ....Lew

 

is a 94 oval or rectangle exhaust ports or does it matter?

 

more of a rectangle

 

Ok cool i am going to try to get the bolts out this weekend the one i will have a problem with is the one that broke on the back pass side of the engine but i am pretty sure i can get the rest of them out. soak them for 2 days with pb blaster then ez out them VERY SLOWLY so i dont break the ez out i am trying to avoid having to take it to a machine shop to get them out.

 

with 8 bolts out you won't get even pressure along the headers... thus you'll end up blowing out the side of your exhaust gaskets and they will leak terrible. If that happens you'll also start pulling exhaust fumes into the cab from the engine bay. did you break them off putting in or taking out?

If you broke them off taking out the old ones (ie rusted in old bolts) soak them with pb blaster for a couple days get some new new nuts and weld them onto the old bolts... after a couple days sitting with pb blaster heat the heads carefully with torch to expand metal around bolts and then take the rachet to them... (make sure not to melt other gaskets or start a engine fire from and oily engine...

If they are new bolts that you over torqued and broke off you can weld nuts to them and take them out... (of course this is all if you have a mig and the header bolts aren't broken off flush with with the heads surface) then you have to use an easy out... or have to pull the heads, drill out the bolt and re-thread with tap and die set. Put up pics if you can...

OH!!! Don't forget antiseeze on the new header bolts when you put the new ones on!

Header bolts are a pain in the ****! especially if they are the old/origional ones that don't have an anti-seeze compound on them.

 

Remember that the more you fool with it and the more difficult you make the fix, the more the shop is going to charge you for fixing it. They'd much rather you come in with a snapped off bolt head than come in with 8 broken bolts flush to the head with easy (never easy) outs broken off in them.

 

yeah they broke coming out i figured soak them with pb blaster for 2 or 3 days and then either use the "pain in the ****" out to get it out or weld a nut to the end of it and pull it that way some of them i may be able to get vice grips on them but others i know i will have to use the above tactics.

 

Good luck. Let us know how it goes.

 

Yea im gonna need it i think i will try the welding thing first because if i do have to take it to a machine shop i dont want a broken easy out stuck in the bolt.

 

get nuts that will slip over the bolt shafts completely... That way when you weld them on the weld will penetrate further down the shaft for a better weld. also try to tightening and loosening them... sometimes that helps to break the bolt free... if you go all the same way you'll end up breaking them. also don't forget that the welder will create heat and tighten the bolt into the heads... let them cool and hit them with pb blaster after your done welding the nuts on.

just remember... idealy you want the heads hot and the bolt cold...

 

so would letting my engine run a little after the bolts cool heat the heads enough to loosen the bolts a bit and after welding the nuts i heard that spraying the bolts while hot not only will cool the bolt but will draw the pb blaster down in the threads and give it better penetration.
