98 Hilux 5L flywheel orientation

[Krankieone]

We have rebuilt the engine some time ago and for a variety of reasons the project stalled.
Today we went to bolt the flywheel back on only to find the alignment marks we made on the crank have been erased and are now wondering if it is an externally balanced engine (if so, how do we know which way to orientate the flywheel) or internally balanced and it doesn't matter how we orientate the flywheel.

I would be grateful for any assistance

I'm pretty certain there is no reference to matchmarking the flywheel to the crank position, and with the marks you have made gone, no specified orientation for installation relative to the crank.

I didn't make matchmarks when I rebuilt my 3L. Had the original flywheel resurfaced and threw it back on.

Pretty sure you are good.
