[QUOTE="railroad, post: 16837901, member: 13485"] [B]Pressurized them up with intake valves fully closed and sprayed oil over the valve stem seal/guide areas of each corresponding cylinder looking for bubbles. Nothing... [/B] Valve seats and faces would seal pressure from getting to stem and guide. Once the valve is unseated, stems can cant, allowing vacuum to pull oil?? Highest vacuum at idle, low rpm and low load, seem to be pulling oil. Higher rpm and engine load, low vacuum. I think diagnosis is right. [/QUOTE]
