Does anyone have experience with oil leaking around the coil packs on a 2006 2.7L 4 cylinder engine? I have 40K miles. It seems PCV related. It gets worse with a new PCV valve installed. The PCV intake hose path is clear when I blow into the crankcase, and the PCV vacuum is strong when I take it off of the PCV valve. Right now I am running a drilled out PCV valve with a hose venting the crankcase to the outside, with the PCV Vacuum line plugged. This gives me the minimum oil leak. When I open the oil filler cap while the engine is running, there is lots of air coming out there. My other car (Buick V6) has no air coming out when I do this test. I don't think my Tacoma air out the filler is normal but it runs great, especially with the PCV vacuum line plugged. Any insight would be appreciated.
Thanks all. Gordon
