anyone know what size the bolts holding the header/cat together? the larger side of the bolt is 14mm...the smaller end (on the header side) is smaller than 12mm, but larger than 11mm.

even with pb blaster this chit wont come off

looks like i'll be heading to the dealership to get these seized bolts off to replace a damn gasket unless someone has a better idea

 

12mm has always worked for me. Maybe yours are stripped...? Try to hammer the 11mm wrench on there enough to where you can work with it.

 

Smoke wrench?

Sawzall?

BFH & a chizzle?

Dremal?

 

good idea craiq. or a dremel

 

Smoke wrench? never heard of that one.

BFH and chissle was tried.

Dremel...that might be in order.... dremel with metal attachment

this pos exhaust system....

How about



or

 

How about you grow some friggin arms and torque the head off the bolts!

Worked for me last week, for better or worse. Of course I used a breaker bar, or some random piece of pipe.. or a jack under the breaker bar and wrench.... can't remember

i tried the jack thing too... no dice.

 

no no no

there is an easy way to do this

get a blow torch and heat them up real good, burn off any rust or build up as well

once they are real hot, like a few mins of blow torch action...

you should be able to turn them

goodluck

and yes im serious and i HAVE done this before

That's funny.

I assumed you used WD-40 and let it soak for awhile before you went at it. It has worked a number of times for me.*Shrug*

I know what Tom means, and I don't think WD40 has a snowballs chance in Hell of doing anything to them.

[shrug] Mine just rusted/fused into one piece so we used the whizzer wheel and cut it off, then we retapped the holes for standard and used some standard bolts, springs and nuts that were laying around.

 

tran got the bolts off, so im assuming they are still in OK condition, but then again, that was a year ago

this time i'll insist on anti seize.

High temp nickel-based antiseize.

Isn't that what the Permatex brand is? I presume this is the most common anti-seize available......

 

You need the screw out things that craftsman sells. They are like a socket with teeth inside of it. They sit inside of a socket more or less, but they also have a drill version. Whenever I did my exhaust I stripped the head completely on the same spring bolt, but these still were able to break the bolt loose with no lubrication.

Their definitely worth the investment



" Craftsman 10 pc. Damaged Bolt/Nut Remover Set, Low Profile Bolt-Out

10 low profile removers, fits sizes from 3/8 to 3/4 in. and 10 to 19mm. Used for removing damaged, stripped, rusted or painted fasteners (screws/nuts/bolts) of all types."

 

And when you brake the bolt off in it just hang a wrench on the welded on nut and break it off two and weld a new on on..

Don't build a honda with out it...........

 

Dear lord....

bring it in, they replace the gasket, and break the o2 sensor. (error code 65).

tommorow they'll look at the issue

 

See you should of just broke the bolt off and then broke off the welded on nut. Every salt belt car we get down here i have to do the same thing to it..

There's your problem

Next time, cut the bolt, cut off the nut and use a longer bolt and double nut it on the other side.
