crankcase vent and oil seperator are the same part? confused

Justin - I totally agree with primetime. The valve cover change is not that bad. Sounds like you have the same symptons. As far as, the leak on the radiator. Are you seeing a huge radiator coolant on the ground after you park? Since, you mentioned that you just changed your water pump. I would check to make sure all the bolts are tight...isnt' there a gasket on the water pump? Can't remember...GL

I changed the pump around 10,000 miles ago. thats fine. once i changed the radiator, the following week I had to replace the hose that connects under the water pump(3/4" hose). I believe those problems are solved but i checked the coolant around two weeks later which is today and my coolant was low again. whats up with that.

Yeah, crankcase vent valve is the same thing as the oil seperator apparently..

Thanks for the insight. Now its time to start shopping for parts.
