I'm installing my header and I'd like to know how much lbs per nut should I torque?

I've heard 20lbs per bolt. Is that about what I should do?

heres a newbie question..

how do u determine how much lbs u r torquing?
like example when u are tightening the nuts for ur wheel

Slightly off-topic... Where's a cheap turstworthy place that'll do a good job rebuilding a whole exhaust? (from headers to muffer).
And how much for a decent catback system? Soft bends, non-chromed... roughly?

im installing my performace header and I'd like to know how much torgue should I put on the nuts. That all I need to know and tomorrow im taking it to get a custom bent mandrel exhaust.

not much...those nuts snap off like butter! Believe me, when I started working at Honda in service, I broke quite a few! And ask anyone, those nuts are generally a bitch to take out if they break off in the block....Im not sure of the exact rating, but the way I judge when they're tight is I thighten them till they're snug and then tighten them down 1/4-1/2 a turn...no more or youll snap the bolt.....

I snapped one of the 4 bolts holding my valve cover.
I have no clue on how to replace it, whether I should even bother, and if I do, where to get a replacement bolt.

mourad:take the valve cover off and determine if the bolt is snapped off insed the hole or not...if the end is exposed, youve got no problems....if it isnt, get out the drill and tap set cause youve got work to do

Id replace it with another honda bolt cause if you leave it like that, oil will eventually seep out

Thanks for the advice civic_fan. Upon closer examination today, I did notice disturbing amounts of oil oozing its way out (it's the bolt closest to the oil filler cap).
Unfortunately, I think it will be impossible to remove it without drilling it out.

Word of advice to n00bs: Follow torquing specs!! Don't go insane on the wrench like I did, "the tighter the better" is a fallacy.

i broke a header bolt. Its still broken, its a really ugly sound. Dont do it.


Now I gotta fix it somehow.

Its a special wrench, called a Torque wrench.. Its bacically a ratchet with a guage on the head that tells you when you hit a specific number (lb),

there are a few diff designs, mines a SnapOn wrench, bacically you dial in the setting on the handle then you use it like a normal ratchet untill the head makes a click sound... that when its hit the proper torque... others are more simple, with a needle that points to a number on a scale... if u need one, im sure Canadian Tire will have one to lend you... Otherwise they are generally expensive tools, but very usefull, if you want to do things the right way...

They serve a few purposes..

A: prevents over torquing engine parts to prevent brakage..

B: Prevents over torqueing of suspention parts to assure they come off again next time somone works on it

C: safety, makes sure nothing is under torqued so much that bolts wont rattle loose...
