ZZ4 maintenance - problem found!
Well, I found the rocker arm causing all the noise. Boy was it loose!! Checkout this short video.
http://www.youtube.com/user/Silverad.../3/HY6it2e-U7c I've loaded three other short videos. While adusting the passengerside, the engine ran on four cylinders! Only the driverside cylinders were firing. Video after the first adjustment. http://www.youtube.com/user/Silverad.../1/sDOiHokViZk Video after third adjustment: http://www.youtube.com/user/Silverad.../0/O1bCGZ5VpAs Notice the idle change from the second adjustment to the third. The ZZ4 cam lope is noticable with only four cylinders firing. I'll finishing it tomorrow. I can't wait to take it out for a spin. No more rocker arm noise! You can hear the exhaust now while standing near the engine bay. I should have made these adjustments a long time ago!! Last edited by gchemist; 03-11-2010 at 09:47 AM. |
