I was changing the PCV in my 90 ls (b18A1) and when I pulled the valve up it broke in half, flush with the intake manifold. Me and my friend tried getting it out and broke a few more smaller pieces off of the remaining valve but the bottom part of the valve is still in there. Now I have run out of ideas as to how to get this last part out...if any of you have run into this problem or have any ideas please let me know...Thanks
