OK, this headgasket repair is getting expensive!! And I am finding that most parts house employees are idiots. Even with the computer and their 20 questions, they couldn't figure their way out of a paper bag!! Of course my very knowledgeable parts guy has been out dealing with family stuff, until today. I ended up buying more gaskets than I needed! But now I have spares.
My experience with the 22RE exhaust manifold:Had an exhaust leak, tried tightening rear studs, they pulled out of head.Took off manifold, it was warped, so I needed to get it surfaced so it would seal.Then because I'd lost 2 studs holes, I drilled out all the holes and put in threaded inserts so there was no way they'd pull out again.And because I'm thrifty, I used SAE instead of metric ( 3/8 vs 10mm) and cut to length a stainless steel threaded rod instead of studs. (and stainless nuts). This is a low torque application, so you don't need grade 5 or 8, and stainless is stronger than grade 2 (close to 5) and it won't corrode.
Secrets to No problems with Manifold to head leaks.#1 Have your exhaust manifold or header surfaced. (Makes a huge difference having a flat surface to seal)#2 use the Factory exhaust manifold gasket. (Its expensive, Good things always are)#3 Replace all the exhaust studs and nuts with new and the correct length. (Use the factory stuff, Its not that expensive and they are unique lengths)#4 Use a torque wrench to tighten the exhaust manifold lock nuts. (Every one of them should tighten to spec, If not it was going to leak)#5 Warm everything to operating Temp, Full hot. Then While its hot, Jump back in there and retorque everything. (WHILE ITS HOT!, NOT AFTER)#6 (optional) I use the copper Headgasket spray/exhaust spray on both sides of the gasket.If you do this You will never have a problem with the exhaust manifold leaking. Do it right, Do it once, and never think about it again.
If you can, get REMFLEX exhaust gaskets! Hands down the best I've experienced! I haven't had to retorque once, and it's been 3 years since the rebuild! They're based out of WASent from my LG-H830 using Tapatalk
That's what I have and I agree with you statement! At the dealership the oem exhaust gasket was 228$, I have tried many different ones that always ended up leaking (yes torques to spec, exhaust side resufaced, bolted from the inside out, lock tite etc) and I have no issues since I instaled the remflex gasket and it cost me around 50$, a good quality piece, it will seal even if the head or header is slightly warped.
Wow,Your local dealer really marks there parts up. $228 ?
Is this it?http://www.ebay.com/itm/1717335120-Genuine-Toyota-GASKET-EXHAUST-17173-35120/182382081964?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D2%26asc%3D20131003132420%26meid%3Da9a1f1096207446093ad991ff4c14246%26pid%3D100005%26rk%3D2%26rkt%3D4%26sd%3D221640303424http://www.ebay.com/itm/TOYOTA-1717335120-GENUINE-OEM-MANIFOLD-GASKET-/221640303424?fits=Make%3AToyota%7CModel%3APickup&hash=item339acaa340:g:LUMAAOSw3mpXHy3w&vxp=mtrGnarls.
That's good stuff.Just do all the other steps and you should be golden.
This is the exact model I orderedhttps://www.yotashop.com/remflex-hi-crush-exhaust-manifold-header-gasket-20r-22r/It is very thick and re-usable, just don't bend it at all! I bent it slightly when unpackaging and I cracked it, it doesn't leak though but they are easy to break if you bend them.
Ummm.. not reusable.. unless you meant on the exact same head and header.. Sent from my LG-H830 using Tapatalk
... I take the whole retorqing with a grain of salt. I doubt it was done from the factory. You think they seriously went over every vehicle starting it and tightening bolts for weeks before they where shipped out?
Downside of Stainless is it galls easily. ...
