L series Exhaust Manifolds

[Logical1]

Hey all, I just searched through 8 pages of results looking for a picture of the stock L16 exhaust Manifold. There is a bunch of posting of them but everybody's flicr/photobucket links don't work anymore. It would be awesome to get pictures of all the L series Stock Manifolds for comparison. If people post up some images or email them to me, I would be happy to host them so they stick around ;) Thx

your in luck! Im about to pull my exhaust mani

[hang_510]

your in luck!

:rofl:

 

i was putting this together too!

 

 

i have found 2 different castings for the non-smog manifolds.

 

different center sections ribbed vs. not.

 

1 has an untapped port resembling where an O2 sensor might go.

no ribbing.

Rofl, I doubt it's for 'her pleasure' :P

Ill get some pics up later today. I believe its a stock L16 mani :P

Look at my build thread in my sig, I'm pretty sure there is pics of my exh manifold, I can't see photobucket pix when I'm at work so I'm not sure

:rofl: glad to see your working hard Ed :lol:

Yeah, I need a media hyped recall like Toyota for some business, friends at Yota are flagging hrs like mad.

N69

 

N22

Go to franks house Im sure there is a pile of them before he throws them away

hang_510 beat me to it...

[Gensaiken]

there's one more variation which is for a round exhaust port head. I have pics some where.

[datzenmike]

Correct Richard, for the W58 on the L20B, '78 and up. All I have is a partial but it has a single large round outlet and round ports.

 

Early L16:

 

 

EGR was used starting around '74 IIRC. So L18s had the small tube:

i only considered NON-smog ported manifolds.

what are the casting number on those^^^?

the ribbing extends furthur down as well...

 

 

looks like they had already planned for this in the casting change. mine is untapped.

Frank doesn't have ANY L motor shit anymore. He makes fun of me (and you :P ) every time I go over there... 'OH its L motor guy!' & calls me Jesse (My name is Jacob) :lol:

 

Thanks for all the awesome pics everyone extra thanks to Hang-510 for the uber sweet comparison pics I'm really hoping to get a true 'reference' for all manifolds and the exact year/engine they are off of. Hang_510 your has the manifold models numbers but not the actual engines they are off of. I'm guessing its the L16 I was looking for...

:rofl:

 

the ribbed came off the L20b that was swapped into my g00n, ~15 years ago (supposedly from a 620???)

the other???

 

my friend pulled the same N69 cast from his stock 69 L16

heres the one from my goon.

This pic shows the back side of the 4-2-1 manifold vs. the standard one.

 

 

here is one with smog fittings blocked off.

 

 

[datzenmike]

Very interesting. Good to know what to look out for.

add the casting numbers off the 2 non-smog. :)

[bonvo]

aha!!! everyone keeps saying that the stock manifold flows as well as a header but i just discovered that a stock mani weighs about double what a header weighs
