header install problems

[bigbird]

welp i finally got a chance to really dig in and try to get thes headers on but just dug my self a hole. i started with the bolts on the cat and they were literaly fused with the flanges. i tried hacking the nuts off but the damn things are so rusted that i cant even knock them out of the flange even with the nut gone. what should i do?

another problem i found is i really have no clue what how to get the rear bank exhaust manifold off. i really want to avoid having to take this to a shop to get it done cuz i know they will charge me out the ass and im not even gonna gain that much from it. any advice from the pros would really help. thanks guys.

Penitrating oil & an impact driver.
Penitrating oil & a breaker bar.
run it back & forth until the rust breaks free.
Or add a minute, or few of torching to both - or if you must, go drive it till it's hot, but careful with burns!




The rear bank you access from under the car. Tho it can somewhat be done from the top if you lay over the bay & have good reach. And don't mind the cuts on your arm (long-sleeve shirt is a must!)

torch em ... or cut them off with a grinder/cutoff saw

PB blaster works wonders. It didnt get my stuck rear wheel off, but it work on lots of other things. Give it a shot!

its lookin like im gonna have to torch it. both the wrench and breaker bar just rounded off the nut and bolt head. i apreciate the help guys.

Did you use the PB Blaster and let it soak for 10-15 minutes?

[bigbird]

what is "PB Blaster"? i was thinkin that was some other term for plasma cutter, which is another option im considering

The plasma cutter would be fun, and scary. Try using the PB Blaster or Liquid Wrench, they will help with the rust.

Best of luck

Its a penetrating oil. Sprays on like WD40

Couple of sprays and soak for 15 minutes and it should get them off.

you can get it for like 4-5 bucks a can from autozone or any other auto place.

oh . im way past penitrating oil, the nuts of the bols have been sheared off and they still wont come out, stupid old cars .

[Curry]

Damn that sucks. I used some to get mine off, went pretty smooth. I had to install a sandwhich adapter and it was a bitch to do with the header on.

I had the mae problem as you with my 95 camry 4 cyl, and I just cut the exhaust and ran it striaght pipe to a canister muffler with back pressure support (silencer).

[Eye8Pussies]

a grinder would do wonders as well
