KA24DE mystery part - dowel pins for?

[xSeraphin]

I bought a torn down KA24DE and am slowly putting it back together. I've come across 2 solid metal pins that I have no idea what they go to. Any help would be greatly appreciated.

In this picture they are next to the hollow alignment dowel pin for the cylinder head.

Helps you align your headgasket during install.

looks like block to trans pins not sure though..

I appreciate the response, unfortunately I can't find a place for them between the cylinder head and block. The 2 hollow dowel pins go in 2 of the cylinder head bolt holes like they should.

Where do the solid pins go?
Do they even go between the head and block?

I took a look at the block and I do see a similar pin above the flywheel side freeze plug. It's thinner though and, well, it's already there!

I'm still clueless :/

not really sure what the solid ones are for.

It's been a while since I've taken the head off my KA, haha.

So far the closest thing I can find to fitting these pins is the hole near the flywheel for the transmission bell housing but that's still only 1 hole. I think what I'll need to do is visit a junkyard and strip down and old KA DOHC until I figure out where they go.

After many hours searching the web and service manuals and pictures and forums and everything else I could think of I came across a single clue to what these could be. Part 11021A at nissanpartszone. There is a channel that goes straight through the block. Originally I found a hole the exact size where one of these would fit. Since the oil pump was installed I didn't notice that on the other side of the block was another hole. With the timing cover off I can look straight through the block and see out the other side. This seems to be either a coolant channel and these are freeze plugs or an oil channel. Either way, this is the only place I can figure they go and in every other picture I can find of a KA24DE - the holes are plugged!

Here is the part : 11021A 240SX PLUG-TAPER

Good info!

Thank you!

NOOOOOO!!! if I'm not mistaken that is the passage that goes from the oil pump to the filter!! If you plug that , oil can't get to the filter housing from the oil pump. I can't see the last 4 pics thou. There is a special open dowel with a built in o-ring that goes there.

I'm sorry upon further review , I was wrong and I think you are spot on. It's late here hehe.
