I was given a complete intake/exhaust manifold for a 78 FJ40. The only problem I see,is the front part of the exhaust is loose.I need to get numbers 15 and 16 from sor.It says it's a spring(15). I can't find anything in the service book or Haynes. This is suppose to bolt up to my 74 F engine. Anybody ever done this? Thanks!
I saw the same thing.The front side comes out easy,and it does look like 2 rings.
I'm going to order from sor and see what happens.Didn't have a chance to order today.I gotta check to make sure the manifold will fit before I order.I'm also wondering how easy it is to put on. I'm also thinking about calling cruiserdan about the parts.
Still don't know where #15 Spring (circled in red) should go? I ended up placing #15 inside the bore of the manifold - there is a lip inside the center section that accepts the elbow - can someone confirm if this is correct?
Noomis - so you bought one ring and one spring, put the ring in one of the two grooves in the elbow, put the spring into the bore of the main section of the manifold until it snugged up to the lip inside, and then slid the elbow in after it?
that would seem to make sense but then why are there two grooves in the elbow? Not asking you as much as everyone else out there. Doesn't anyone know exactly how this is supposed to go together?
In the 3-4 I've had apart there have been what appear to be two rings in two groves on the elbow and I've never seen a spring.
You need 4 springs and 4 rings to do the entire manifold.
In each of the 4 grooves (2 grooves on each side), put in one spring, then place a ring over the spring. The springs are underneath the rings, that's why they can't be seen. I'd stagger the ring gaps too. The spring is supposed to hold the ring snug against the inside of the center section of the manifold.
The ring itself barely fit in the groove - and had its own "spring tension" - i.e. I had to compress it to get it to fit in the bore. If anyone is successful in getting the spring in under the ring - let us know.

The first groove had a ring in it that appeared to be to be unremoveable - no gap anywhere in the ring - so I placed ring in the remaining groove and called it a day.
**Edit - this is incorrect, both rings have a gap in them - the first ring was so compressed that it appeared to be one continuous ring**
My main leak was caused by the sealing surface between the manifolds and the head being out of alignment. I had them milled flat and it should seal fine. As for the elbows sealing - the ring is actually behind where the exhuast gases exit - not sure how much back pressure actually comes back out there - we'll see.
Okay, pulled the elbows off and it is exactly as Toad described it - the #15 "spring" goes in the groove, followed by the #16 "ring" on top of it. It actually went together much easier than I though it would - as the recieving end on the manifold is tapered so the ring on the elbow compresses as you slide it into the bore.
This weekend I finally replaced a badly leaking collector (donut) gasket, when fixed, made it much easier to realize that I have a leak coming from my rear elbow seam. It is actually a pretty bad leak, so Nomis, there is quite a bit of pressure on those seams.
My question is, my manifold seems to be tight everywhere else, as does my intake; can I unbold the EGR hardline from that piece of the manifold, unbolt it from the block, and then remove it without taking off the entire manifold? How is it to remove the elbows from the center section of the manifold. If they just slide out, if you can get it unbolted, it looks like it can be repaired without a full manifold removal and rebuild? Oh, and I'm talking about a 60 here, so the 40s and 55s may not have the EGR BS in their rigs. If so, ignore that part. This seems to be the best discussion in the forums regarding these elbows, so I'm asking here rather than start a new thread in the 60 series (just a note for the thread mongers!) So, can I take it off separately, in your experiences?
Matador, the front elbow on my '76 was held in by a stud - If yours is the same, I don't see any way to rotate it out. The rear elbow was held in by a bolt so it could slide out in theory- but there was very little room back there with the firewall. Removing the manifold isn't as bad as it sounds - it may be your only option.
