The early M103 engines had bad valve stem oil seals. If it is using a lot of oil, it is time to change them. With this many miles, you would be better served to do a valve job, replace valve guides and use the updated seals.

I would not do this without first doing a compression analysis to ensure that the cylinder/piston integrity warrants it.

Good luck,
