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?

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

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.

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 :D

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.

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

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

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.

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.

there were lots of people who doesnt know was saying to dont install the exhaust manifold heat shield well the company install this part for some reason and now i know this control the vacium,carbrator,accleration and auto choke.and onething more this is good for the cold country like canada montreal.and ddude2uc my car is in great condition i dont want my car look like trash made like u said wrap some aluminum foil aroud it...lol anyway thanks for other idea i did drill and removed the bolts.

I'd put money on it being a problem with the choke. More specifically the choke puller not operating.

Well mr. I replyed to you way back last month and offerred you the whole manifold with heat sheild , go back and look. whollly donkey wood man
Yep if your carbed, you have an experience to go thru with choke problems that everybody here who has carbed cars must have experienced as well SO LOOK SEARCH FORUMS, the kind folks here at 3geez have spent a lot of time and effort to provide this information textbook style for your convienience. There really is not a quick answer, but wait, last time I said that guess who chimed in with help, are we paying attention? Im very sorry you had to pay so much for that part, and true I have one in my carport going to throw away most likely, I figured you had a solution, I would have given it to you if yo paid shipping.. ouch....I also I dont understand exactly why you HAVE to have one, unless you live in extreme hot temps, it serves to keep heat away from your electronics and and upper engine, for cold temps you can get hot air from just leaving the hot air duct by the manifold with a wire hangar of some sort.

I can't remember the exact temp drop but I believe it's up to 30 degrees cooler then the outside air. it depends on air velocity etc. this can cause ice crystals to form on the surfaces inside of the venturi. this can block the jets and cause the car to stall. this will often happen after having been at cruise for a while then going to idle. the surfaces in the carb are so cold ice instantly forms. in addition to the heated air,our cars use a heated carb base plate,coolant through the carb itself,and a heated intake manifold. in case anyone asks it's the same thing as carb ice in airplanes. and fuel injected cars don't have venturies so don't suffer from the same thing

The fuel that is changing phase from a liquid to a gas in the venturi is responsible for the temperature drop. This is the principle behind refrigeration, right? Ever spill gas on your hands and it feels cold as it evaporates? When carbs freeze, the ambient air is usually above 0 C, and very moist, however the evaporating fuel drops the temperature of the jets and venturies to far below 0. The water in the air precipitates out as ice, blocking the air flow around/through the jet/venturi and chokes out the engine.

In this guy's case, I think his choke is staying on too long/much.
