22 re exhaust manifold
Hi
I'm new here
I'm looking for instructions to replace an exhaust manifold on a 22re engine fro my 95 dx short bed?
any help?
the head gasket was recently replaced so it has been "off" recently
Thanks!

first soak all the bolts with pb blaster for a few hours then take the 2 14mm bolts of the cat then with some really long extensions take the 3 14mm bolts off the down pipe then take the heat sheild off the manifold then take the 2 bolts off the air injection pipe then take all the bolts of then manifold wich are 14mm also sand down the gasket area .... your going to need new bolts from toyota

I would just take a grinder to the CAT bolts and replace them with stainless. If yours look like mine, a wrench wont even grab the spereical rust balls that the bolt heads have become.

i do it this way...
unbolt the exhaust clamp on the bellhousing, then remove the 3 nuts from the downpipe flange(often times the factory lock nuts will be siezed to the studs and pull the studs out with them). after that, you can remove the heat shield and unbolt the 8 manifold bolts, and the 2 for the air injection pipe.
most napa/other parts stores that sell dorman hardware in the orange bins will have m10x1.25 studs available. better to get ones that are too long vs too short if necessary. then for each stud, i get a flat washer, a hardened lock washer, and a regular nut. seems to hold things on there quite well. i bet an all metal lock nut(stover nut) would work even better, but they're hard to find in metric, much less in a wierd 10x1.25 thread size.

I've had an ongoing situation where the rear cylinder can be heard firing when the engine is cold. The exhaust manifold gasket is leaking. I tightened the bolts on the back of the exhaust manifold, and it went away for a while, but it's back. I think the head got a little stripped when the engine was overhauled. I don't think it will help me to tighten. I think it will probably take a helicoil to fix it.

I put the same header and their complete exhaust system on my 2wd. Let me know if you need other info...

our manifold had a 1/8" warp. Always leaked at rear cyl.
We replaced the manifold (napa new). Also had to helicoil (2 stripped, did all while we were there and had the tools) and new studs.
