JoeR Posted January 27, 2012 Report Share Posted January 27, 2012 So I'm pretty sure there is a leak somewhere in my manifold, either where it meets the block or a crack somewhere. I went to a wrecking yard to see if I could get another and noticed that both manifolds I found were cracked in the same spot. Has anyone had this same problem? I will post a picture when I figure out how to do that. Quote Link to comment
danfiveten Posted January 27, 2012 Report Share Posted January 27, 2012 My manifold is ceramachromed to prevent that shit from happening. My lz2.2 gets really hot, and my car went through 2 of them. Quote Link to comment
nismo dr Posted January 27, 2012 Report Share Posted January 27, 2012 Nissan's (most cars really) are prone to cracked manifolds, you put 100k+ miles of extreme heat and cool cycles on cast and well..... Quote Link to comment
nissanprerunnerdavid Posted February 22, 2012 Report Share Posted February 22, 2012 i have had the same problem. where would i find a new manifold online?? i have only been able to find the gasket package but not the actual manifold? any help?? Quote Link to comment
datzenmike Posted February 22, 2012 Report Share Posted February 22, 2012 You won't find new ones, they haven't been made since '74? Get a used one from a wrecking yard or ask on here. Quote Link to comment
nissanprerunnerdavid Posted February 22, 2012 Report Share Posted February 22, 2012 really?? i had no idea. well if anybody has an exhaust manifold they want to sell let me know:) Quote Link to comment
ggzilla Posted February 22, 2012 Report Share Posted February 22, 2012 The Z-series manifolds are still listed by nissan. For example, the 1985 720 manifold for Z22 is listed at $245. Give them a try. Or on Saturday go to some wreckers and spend $39.98 and a little work. Pick-n-Pull richmond lists 5 720s, and oakland lists one. Quote Link to comment
nissanprerunnerdavid Posted February 22, 2012 Report Share Posted February 22, 2012 thank you!! i will give them a call and find some time to get up there!! Quote Link to comment
ggzilla Posted February 22, 2012 Report Share Posted February 22, 2012 Take your old manifold so you can compare. Z20/Z22/Z24 look a lot alike, buy may not connect up the same. Quote Link to comment
datsunaholic Posted February 22, 2012 Report Share Posted February 22, 2012 Z20 and Z22 exhaust manifolds will bolt onto a Z24 but may not have the same EGR/air injection tubing placement. Quote Link to comment
JoeR Posted February 22, 2012 Author Report Share Posted February 22, 2012 There seem to be a lot of sellers on ebay selling manifolds that supposedly fit the Z24. They run anywhere from $80-$100 shipped. Anyone have any experience with these? Quote Link to comment

nissanprerunnerdavid Posted February 28, 2012 Report Share Posted February 28, 2012 Is there low end torque that is lost when you put a header on?? Quote Link to comment
