My engine is a 91 and both i/h and heads look like B and D in Jerry's photos. There was no signs the oil entered the intake passageways, it appeared to come out of the i/h pvc areas. I am having problems passing CA's smog test, high NOx and lean burn indicated from the tests. One of the possible causes is malfunctioning pvc system. I'm thinking the pvc system may not be able to cope with the amount of oil coming through the system. Possible solution, catch cans?
