Klitch, thanks for the bearing info but I am not going to remove the heads to repair the cam journals because of cost and the fact that who knows what other piece of cheap metal or plastic is gonna fail and muck up the rebuild.
JMC, thanks for the tip on Romeo build having bolt on cam gears and I also heard that the 4.6 Mustang cams should work. So it's back to the junk yards next week. For some reason the 20+ Ford modular heads I saw here in San Diego had all pressed on cam gears, aren't we special!
RacingJake, you might be right about the low oil pressure thing but I saw a lot of 5.4 heads with scored cam journals all 2000-2002 PI heads so maybe it's just normal like piston slap and torque converter shudder?
Here is a little food for thought....I wonder if the reason some 5.4's get great gas mileage is because they are Romeo build and the bolt on keyed timing gears do not turn just a little and screw up the performance just a little??????
How about a gas mileage poll based on engine build and tell us how to determine the build?
