hi everybody...new member tom aller. i have been the proud owner of a 94 cherokee 4.0 for 10 years. it became a gp in california, so, i pulled the head, rebuilt reinstalled, not my first. started right up...then the oil stays in the valve area and wont drain. oil pressure goes down..eventually white smoke pours from pipe, filling entire neighborhood. oil disappears from oil pan, only to slowly drain back much later !!!
