Bad machining that took 30 years to happen? Rich
-
I want to update everyone on the problem with Z. (1971 240Z 250K miles 150K since engine rebuild.) The problem ws that I was throwing the #3 intake cylinder rocker arm off the engines every so often. I had to take the head off to find the root cause. The valve seat on #3 was loose, drop down out of it location and would stick somtimes, jamming the valve and kicking the rocker off. Go figure, it takes 150K and 30 years for a valve seat to come loose. The solution was easy new seats and a valve job (the seats were all origional). It runs good now. Any opinions on why the seat came loose now? Rich Nedinsky San Jose, CA
