1987 Pathfinder Hoses

[August59]

Just wondering if anyone had any good ideas as to how they went about replacing hoses that appear to have been long discontinued?

Ex; PCV hose from valve cover. ID dia. on each end is different as well the hose from other valve cover to air breather has different id dia. ends

Unless anyone still knows of a source for these because I'm batting zero.

In past I've went with smaller diameter hose and use heat gun to stretch the small end. This works, but it thins and stresses the hose pretty be, but it was cheap hose may try again with higher quality if possible.

Thanks ahead of time for any feedback
