I'm not sure I'm buying it...

If you had that much pressure in the crankcase, enough to start blowing seals, I don't think the PCV valve or the dipstick would stay in place...

When you pull the PCV out, do you have massive amounts of blowby coming out the hole ? Is oil running up and out yer dipstick tube ?

Have you done a compression check ?
