Q: so if it is a manifold problem whats the procedure pull the manifold and look for the leak. thats what id do. fix the plenum gasket while you have the manifold apart remove the plenum pan and replace the factory gasket with a bead of rtv - theyre known to leak oil into the intake as well. id replace the bypass hose at this time since more often than not you wind up destroying it to get the manifold off. ... i am going to ask a stupid question -- as far as i know a plenum pan / gasket is inside or behind the intake manifold -- would you know if an ol 86ish d150 would have one dont know much about this and i think a cracked manifold is a lot more common on an sl6 rach .
