I'm not the best person to answer this, but since you're so anxious I'll throw in my $.02.
The exhaust manfold on a 22R uses 4 studs in the head on top and 4 at the bottom (top and bottom studs are different Toyota part numbers). The only bolts used hold on the EGR air tube and the aluminum heat shield. RE manifolds should be the same or very similar.

Yeah, they're all studs. I just replaced all of mine (1994 22RE) a month ago as three of the eight were loose and their holes would not grip the threads. Got new set from Toyota and a Helicoil set on ebay, and redid them all. I used high temp thread lock for install (also brand new manifold gasket) and anti-seize for nuts (bought new nuts through Toyota - about $2.25 each!). After installing and driving about sixty miles I re-torqued them all.
Before I tackled this I read every post on YT I could find on doing this. Apparently, according to a few posters, some good hardware stores carry the same size studs and they worked just fine. Yes it's getting cold outside and you might try fitting the one hole with a stud it will grip, maybe setting it in with threadlock (which has to heated about 500 degrees when you go about re-doing it correctly when spring rolls around...).

I just fixed my manifold leak a couple months ago. Leaking at the #4 exhaust. My manifold was warped so i got it resurfaced before putting a new gasket on.
If yours is leaking there is a good chance your manifold is warped. You can put a new stud and bolt on to see if the leak stops but be very careful not to strip the threads in the head. The stock studs are short and don't engage enough threads to hold a lot of torque. |

Look up part numbers at http://www.toyodiy.com/parts/q.html, which thankfully is now back online after being down for several days. Quote:
My exhaust manifold didn't leak, but the shop said it was .008" out, so they trued it. IIRC, the book says .003" is the max warpage allowed.

Ahh, okay so it is a stud.
I will go order (or perhaps they will have it in stock) a stud and nut tomorrow. Im hoping that it just loosened off and fell out. I recently fixed the bellhousing clamp. One bolt was busted and one was missing, so I had to find a new bolt. Heres hoping the threads are fine and I dont have to do anything else. If we had the $$ I would be buying a header!

"How are these studs supposed to be installed in good, fresh holes? I'm using a new head. What approximate torque? Use thread locker or not?" - Flyingbrass
I was referring to half-a$$ing the repair if one wants to avoid working with cold metal on a cold day. But even then, and even using threadlock, you'd need some good threads to work with. For FRESH holes, for a NEW head, from what I found out, I would only install exact matching studs. I got mine from the dealer because i was real antsy to get her done and didn't want any problems. (I'm still learning never to rush ANY of this kind of work, even on a warm comfy day or in a totally equiped garage...). And get someone to measure the surface of the manifold regarding warpage. Approximate torque is 33 ft/lb, and thread lock is highly recommended. Re-torquing after a hundred miles is also recommended. Over tightening is not. Good wishes to anyone doing this. I hope this helps.

I had a few stripped holes in my head, and was missing a stud in the same place. I drilles the holes out, taped them to 7/16 and bough all bolts in grade 2 and reinstalled manifold with new gasket and bolts. Worked like a charm!

I would "poop-can" the stock locking nuts and go with a split lock washer and grade 5 or grade 8 header hex nut. The crimp style factory nuts are not good because they tend to clamp up on the stud while scoring the threads, and twisting the stud in the head. You will need to check and recheck the hex nuts and lock washer option until you are satisified they are holding tight. That's just my worthless opinion. gNARLs.

Oh that place is so common! One of the bolts there was missing and the other was crossthreaded. Had to drill it out and heli-coil it! It sucked pretty bad. I think its time for a damn header... Quote:
Just threaded it in and snugged it down. It really felt like it was starting to let go so I didnt want to really get any torque on it. I have a feeling the lost stud was like this for the 3 years that my girlfriend has had this truck. In anycase, I got the stud+nut in, not that tight but it stopped the leak. The real test is when she drives it back home tonight. An hour drive! fingers crossed!!

Mine went out driving home one evening. I had to drive around sounding like a most sunfire's and cavaliers for a couple days.
Mine had been leaking for over a year (since I bought the truck), I knew about it when I bought my truck. Finally lost another stud and it sounded like a whoopy cushion going down the road. I got a new gasket and new studs/nuts. Remember, longer studs go up top for the egr tube. I found this one out the hard way. It was a pain since I didn't had a stud remover/installer, I was doing the double nut trick. Plus I figured it out on the last stud. D'oh!!!

I checked it again this morning after the 100km drive back last night. I snugged it a little more, but it felt just as tight as it was yesterday.
I have a feeling this has been like this for awhile.. Perhaps when they did the motor on it just before we got it. They didnt do the best job!

The inner tie rod ends are pooched, the grease fittings got smashed into the frame and it punched out the threads. The outers got ripped and are toast. Sucks I replaced both tie rod assemblys when I did my BJ spacers.. I need to repack my wheel bearings and lube the spindle bearings. Oh and the control arm bushings are starting to show their age, I wont do those for awhile tho! I also need to install my Soneran steel IFS brace.. Haha, sweet, sfa is fun! Quote:

crap lol tons of stuff to do. sounds like me a year ago lol. just get a sfa and get rid of that ifs lol. SAS might be a better route than fixing all that stuff then wanting sas later on? you should have seen my knuckle, the cv shaft could move side to side inside the spindle like 1/4 inch each way lmao. so worn out. i was driving and i would get a big whine and vibration and would have to jerk the steering to the right to get it to stop for anothrr km haha.
weird stuff happens at stave when it gets dark lol, cars burn, people get drunk and high and do some weird stuff lol
