OK can't figure this out. When the pcv port on the throttlebody clogs up, oil pressure drops and I start blowing oil onto plug 1. Clean the tb and it works great. Done this for years, now all of a sudden the tb IS clean and I'm still losing pressure and it's blowing clean out through the tb. changed the pcv several times, still no go. any ideas?

 

Have you pulled a valve cover to see if the oil drainback holes are clogged?

That's a very good idea. I'll check that tomorrow.
