need little help :)

[accord89carb]

i want to install new exhaust manifold heat shield but the bolts in my manifold are gone fully rusted i like to know what is the way to open the bolts or if i cant open is there anyway to brake the bolt myself without light.is it easy to drill?or the bolts are very solid?

[MessyHonda]

use some penetrating oil...like PB blaster..they should sell it at any autoparts store.

[ghettogeddy]

if that dosent work craftsman make a good bolt out set i had to do the same thing when doing the oil pan one of the exaust pipe bolts was frozen

[Listen2myBASS]

or just heat or cut em off

[shepherd79]

you can heat them and try to remove it very easy.

[accord89carb]

thing is i dont have gas system to open the bolts is there anyway to open the same bolt or if i break is it easy to drill and make new thrad?

[Jasonf860]

To drill and tap new threads you'd probably have to remove the manifold. Not much room in there to get a drill in. Mine were rusty too and they came out very easily. I'd say try some PB Blaster, Deep Creep, K'nocker Loose, or some other penetrating oil. Soak them good and let them sit for 1/2 hour or more to let the oil penetrate. Just remember that once you get it all back together, all that penetrating oil will smoke like crazy when your manifold starts heating up.

[smufguy]

i don't know why you would like to use the heat shield, but if you like you can just unbolt it, if they break, drill and re-tap the holes if you would like.

PS: If nothing works, metal hose clamps always do the job right

[accord89carb]

Thanks guys for giving idea i will try

[shepherd79]

you can always take the car on a high rpm drive.
let the manifold get really hot and try removing when they are hot.

[lostforawhile]

those dam bolts are almost impossible to get out,tried everything,finally got another manifold from a JY I needed those to hold up my purple aluminum brackets for the AC and PS hoses. I still have a manifold here with busted off bolts in it. really the best way to get those out is to clamp it to a bridgeport mill and drill them straight out,then helicoil or just tap for a bigger bolt and drill the holes in the heat shied bigger. if you have them drilled out,let a shop replace the lower three studs too. they have a habit of stripping out. if they do the manifold will have to be removed to fix them. studs and bolts in cast iron manifolds should have their own designated cuss words. oh,if you get them out,put in studs,if you use a nut with a lockwasher and a little antisieze they will never give you a problem again.

EDIT-6 point socket, PB Laster, maybe small butane torch.

[accord89carb]

Thanks alot guys i will try.thanks for info

[2oodoor]

Thanks alot guys i will try.thanks for info

I have one in great shape how much you give me for it?
For all the trouble, your better off taking your pb blaster and 12 mm gearwrench and socket with one inch extension and 4 inch extension and go to local pull it yourself junkyard.
I will sell you mine for ten buck plus you pay shippping, that sucker is heavy so it would be better for you to get on from the jy.
Any of you guys who responded live near accord89carb, and have header on your car, and dont need the manifold or heat shield, hook the man up yaw...

the only fasteners I had trouble with on mine was one of the 14mm on the downpipe wrung off the head so I tryed hammering on a el cheapo socket one size smalller and tryed it , usually that works but not on this one ,it just rolled off. To get it off I cut it with the death grinder. 5inch sidegrinder with guard taken off and a 8 inch stone cuttoff wheel mounted on it. It works good on exhaust pipes, but keep your face away from it and wear gloves...if anybody is crazy enough to make one up like that one I did. always check the condition of the wheel before you turn it on, if it has been damaged 20,000 rpm will shoot it off like grenade shrapnel

Thats what I'd do.

Have a set of extractor sockets handy just cause of the rusty heads though.

[accord89carb]

hello guys i bought the extractor socket i maked hot the engine and i sprayed the bolts with wd 40 when i tryed to open the bolt broke so tell me what should i do know?

[Jasonf860]

get a new heat shield, if you can get both bolts out, broken or not, Put the new shield in, use hose clamps to secure it. Just my .o2

[88Accord-DX]

Without pulling the header off, it would take a 90 degree drill to drill the bolt out & re-tapp the threads or heli-coil it. The bolt preperation is critical, hitting the middle with a punch with the bolt squared off. New drill bits while using PB Laster on it makes the process faster & bits last longer. Good luck...


If it is too much trouble, the hell with the heat shield.

[AccordB20A]

good good your problems solved. as i said in another thread... the angle grinder is your friend. shields suck face and should be chopped out and never re-installed

[smufguy]

Amen, Amen and Amen.

PS: Like i mentioned above, why the struggle to get the heat shield back up?

[accord89carb]

do you mean you paid 50 bucks for the little tin heat shield,or the manifold? if you paid 50 bucks for the heat shield itself you got screwed big time. I could see that for a manifold. why would you need to replace the heat shield anyway? it just has holes for the bolts,if the bolts break it comes off. If you needed a heat shield I would have given you one,I have a bunch of them around here somewhere. if you have a manifold off the car ready to put on,take it to a machine shop and have the three studs on the downpipe replaced. it's worth the money. they will almost always strip sometime in the future. they will break when you try to remove them, a good automotive machine shop can get them out easy. it'll save you a lot of time and aggrevation later. if you can find them put in stainless studs,or put in metric stainless bolts and cut the heads off. these will be far likely less to freeze on the nut threads later. also use lockwashers on the nuts and use antisieve on the threads. ARP also sells the studs that will fit in there,they are much higher quality then hardware store studs and less likely to break.

[shepherd79]

dude you got owned. I can get heat shilds at junk yard for less than $5.
