So I have a bad intake valve as discovered by comression testing (you can hear and feel the air coming through the intake with the valves shut when I put compressed air into #2 cylinder.) Can I repair and or replace the 1 head or do I have to do both heads at the same time? I was looking at getting a rebuilt head for 300$ but I don't know if 1 rebuilt head and 1 original will cause any problems.With 220K miles on the engine, for under 400$ I could get another 150K miles or more from the rest of the engine but I don't know if 1 new head will cause a problem. Also, it is odd to me that the same cylinder on 2 different 01 Siennas have developed a bad intake valve. Is there a known issue that would cause this? Any other owners have a bad #2 cylinder intake valve?
