After searching for a PCV grommet w/a1.5 ID,finally figured a way to do it.I used a breather grommet then got a Ford pcv w/a 3/4"od,put it in a short piece of 3/4"heater hose which sized up the OD to about an inch,then stuck that into the breather grommet.It fits real tight and will get me by until,if ever, I find the right grommet.The valve covers come with a grommet that had a pentstar stamped on it but fell apart when I pulled it out .
