Is this normal? If not, any ideas where it would be coming from.

Thank you goduars (get it)(I kinda like that one)

 

normal, make sure youre using the new style green orings. They seal much better, we at the shop are also now working on different ideas to reduce this since I believe its the number 1 cause for misfires on cylinders 1,3,5 which are fed by the lower intake. When the oil vapor which comes from the crankcase goes through the intake it settles out in the lower plenum as your pics show, when it becomes heavy enough, it cause misfires on these cylinders. The things Ive been working on with a couple customers is switching to a 40w oil, cleaning the intake passages, and as of yesturday 1 customer is going to start using engine restore to increase ring seal and reduce blowby. All are much cheaper and better fixes so far than thowing in 3 coils, plugs and shipping..especially since it always involves removal of the intake and subsequent labor fees

 

Thank you Brutal !!!!
