Pass or driver?
Either way, you can just pull that sides head and check the gasket, head for cracks, and check the cylinders for cracks.
Cracked cylinders aren't as likely in a 95 w/ 929, 141, or 599 block. Mostly a 97-00 506 issue. Also a cracked cylinder or block usually drains coolant onto the oil pretty fast
Get a full set of head studs or new bolts and both head gaskets. Change the other when convenient
