Well i dont know i just copied the title from the Thai Fb. but they posted this pic maybe to see the inner parts?? or will this help for some?

[Daox]

Great pics! I think I'll add them to the 3A92 thread we have. Thanks!

[Eggman]

Yes. I can pick out where the engine block heater fits quite plainly, without all the other stuff getting in the way.

Muchos gracias.

Great pic of the 3A92 long block! I LOVE how there is nothing on the firewall side of this motor but the exhaust. Thoughtful design.

Hey Mitsumi, mind if we change the title to something like "3A92 long block photos" or some such description?

[Mitz]

For me I would prefer the title "3A92 Engine Block Photos"

1st pic, just to left of intake port...

Is that the cam actuator valve? (whatever it's called, high/low lift actuator)

[Mitz]

Oil feeder control valve?

Oil feeder control valve?

Yes that's it!

Looks really easy to tinker with. Just an open or closed spool valve.

One might wonder what power gains could be had by opening it sooner, using a rpm-window switch or something similar.

Granted it wouldnt be "smooth" anymore, and you would need a wideband/reset tool to play.. But would be neat experiment for those looking for (probably quite a bit) more low-mid range power

Evo / eclipse owners would know more#!

Oil feeder control valve?

What's it's purpose?
