Blue Smoke

[tjvap]

88 PT 40 8V92 Coach has been parked since July,Wife and I Have been
deployed w/FEMA in Oct I was home and started it,no problem.Recently I
was home for a couple of days,started it,started right up, white smoke
as normal after sitting.But then Blue smoke, that didn't stop,after
ten/ fifteen minutes or so.It's never had Blue smoke.Now I'm deployed
again and it's eating at me what could be the cause.can someone relieve
my concerns.Like maybe it needs a good hot run or some thing Thanks
