KA24DE mystery part - dowel pins for? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

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.

Dowel pins look like the bellhousing alignment dowels and the other is a head alignment dowel

I see a dowel pin in the block above the flywheel side freeze plug. It's a bit smaller than these two. There is a hole near the crankshaft on the flywheel side where the pins fit. There is only one hole. I don't have a transmission/housing so I can't compare the pins that way.

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

Looks like a DOWEL-BLOCK TO HEAD. This 2 is used on the block surface (head gasket side) to align or mate when installing the head.
