I recently did head gaskets on my 87 gl wagon because i was getting oil in the coolant. I bought a regasket kit for the top and bottom end and have been replacing lots of things. Although, i noticed in my hanes there is a "crankshaft o ring" and "backup ring" right where the block splits. I read a service manual online and it called it a coolant passage o ring. I was wondering if anyone knew if these go out very often and if they do can it cause oil in the coolant? I really don't want to redo my head gaskets :(

They don't fail - don't worry about it.

Hey cool, thanks for the quick response! I figured something so hard to get too would be fairly reliable. I won't worry about it, time to put my engine back in

I could see it leaking coolant into the oil, but not the other way around.

There is no oil at the top of the block.:rolleyes:

And they don't fail really. If it did, you'd have to remove the heads and redo the headgaskets to split the case to get at it anyhow.
